Q2 2024 Highlights
Second quarter financial results showcase solid operating performance amid stronger copper and gold prices
•The Caraíba Operations produced 8,867 tonnes of copper in concentrate during the quarter at C1 cash costs(1) of $2.16 per pound of copper produced
◦Mill throughput volumes at Caraíba continued to benefit from the successful completion of the mill expansion in late 2023 with tonnes processed up 12.2% quarter-on-quarter and 17.9% compared to Q4 2023
◦Higher processed tonnage contributed to a 9.6% increase in copper production quarter-on-quarter
•The Xavantina Operations produced 16,555 ounces of gold during the quarter, resulting in C1 cash costs(1) and AISC(1) of $428 and $842, respectively, per ounce of gold produced
◦Tonnes processed increased 6.9% quarter-on-quarter while mined and processed gold grades remained elevated at 14.00 grams per tonne ("gpt")
•Second quarter financial results were bolstered by stronger metal prices and a favorable exchange rate environment, which also contributed to another quarter of record gross profit at the Xavantina Operations. While a stronger USD relative to the BRL benefited operating costs and capital expenditures during the quarter, it resulted in non-cash, unrealized foreign exchange losses primarily related to the translation of USD-denominated intercompany debt in Brazil for which the functional currency is BRL
◦Net loss attributable to the owners of the Company of $53.2 million ($0.52 per share on a diluted basis)
◦Adjusted net income attributable to the owners of the Company(1) of $18.6 million ($0.18 per share on a diluted basis)
◦Adjusted EBITDA(1) of $51.5 million
•During the quarter and subsequent to quarter-end, the Company achieved several important milestones at the Tucumã Project, where ramp-up to commercial production is now underway
◦Completed mine pre-strip and commenced full mine operations in late-April 2024
◦Operational License awarded by the Pará State environmental agency, Secretaria de Estado de Meio Ambiente e Sustentabilidade ("SEMAS") in mid-June 2024
◦First batch of copper concentrate produced on June 24, 2024
◦First 24-hour shift of continuous mill operations completed on July 7, 2024
◦First saleable copper concentrate, which exceeded process design concentrate grade targets, produced on July 18, 2024
•At quarter-end, available liquidity was $169.8 million, including $44.8 million in cash and cash equivalents, $100.0 million of undrawn availability under the Company's senior secured revolving credit facility, and $25.0 million of undrawn availability under the copper prepayment facility. In May 2024, to support the commencement of production and associated working capital needs at the Tucumã Project, the Company entered into a $50.0 million non-priced copper prepayment facility. Through the end of 2024, the Company has the option to increase the size of this facility to $75.0 million

Reaffirming full-year production and copper cash cost guidance; updating other 2024 guidance ranges to reflect H1 2024 performance, including exceptional year-to-date unit costs at the Xavantina Operations driven by elevated gold grades
•The Company is reaffirming its consolidated copper production guidance of 59,000 to 72,000 tonnes in concentrate, with production expected to be weighted towards H2 2024 largely due to the projected ramp-up of production at the Tucumã Project
•Contributions from the Tucumã Project, combined with significantly lower concentrate treatment and refining charges, as well as a more favorable USD to BRL exchange rate, are expected to result in lower consolidated copper C1 cash costs in H2 2024 compared to H1 2024. As a result, the Company is reaffirming its full-year consolidated copper C1 cash cost guidance range of $1.50 to $1.75 per pound of copper produced
•The Company is also reaffirming its increased 2024 gold production guidance range of 60,000 to 65,000 ounces for the Xavantina Operations, and is lowering its full-year gold cost guidance to reflect exceptional year-to-date cost performance
◦C1 cash cost guidance is being reduced to $450 to $550 (from $550 to $650) per ounce of gold produced
◦AISC guidance is being lowered to $900 to $1,000 (from $1,050 to $1,150) per ounce of gold produced
•The Company is narrowing its full-year capital expenditure guidance range to $303 to $348 million (from $299 to $349 million)

Consolidated copper production on track to more than double over the next year as the Tucumã Project ramps up to commercial production
•The Company projects that production levels of 80% of design mill capacity and 80% of design recovery rates will be achieved at the Tucumã Project by the end of Q3 2024
•At the Caraíba Operations, main shaft sinking at the Pilar Mine's new external shaft is progressing on schedule, with a projected depth of approximately 600 meters expected to be reached by year-end

The Caraíba Operations delivered quarterly copper production of 8,867 tonnes in concentrate at a C1 cash cost of $2.16 per pound of copper produced. During the quarter, mill throughput volumes continued to benefit from the successful completion of the mill expansion in late 2023 with tonnes processed up 12.2% quarter-on-quarter, contributing to a 9.6% increase in copper production compared to Q1 2024.

Tonnes of ore mined in Q2 2024 included:
•Pilar: 466,991 tonnes grading 1.25% copper (vs. 454,610 tonnes at 1.23% copper in Q1 2024)
•Vermelhos: 228,626 tonnes grading 1.00% copper (vs. 227,166 tonnes at 1.21% copper in Q1 2024)
•Surubim: 201,544 tonnes at 0.63% copper (vs. 106,556 tonnes at 0.65% copper in Q1 2024)

Contributions from the three mines resulted in total ore mined during the quarter of 897,161 tonnes grading 1.05% copper (vs. 788,332 tonnes at 1.15% copper in Q1 2024).

The Caraíba Operations are projected to produce 42,000 to 47,000 tonnes of copper in concentrate for the year. While copper grades and production are expected to increase in H2 2024, the Company is guiding to the low-end of its full-year production guidance range.

The Company is maintaining its full-year C1 cash cost guidance range for the Caraíba Operations of $1.80 to $2.00. Unit operating costs are expected to be meaningfully lower in H2 2024 compared to
Ero Copper Corp. June 30, 2024 MD&A | Page 5

H1 2024 due to higher anticipated copper production, improved concentrate treatment and refining charges, and a more favorable USD to BRL exchange rate.

Exploration activities during Q2 2024 at the Caraíba Operations continued to focus on advancing the Company's full-year exploration objectives of (i) extending high-grade mineralization within the upper levels of the Pilar Mine and near underground infrastructure in the Vermelhos Mine, (ii) delineating extensions of regional targets with known copper mineralization located near the Caraíba mill, and (iii) drill testing regional nickel and copper targets in the Curaçá Valley

The Xavantina Operations achieved quarterly gold production of 16,555 ounces at a C1 cash cost of $428 and an AISC of $842 per ounce of gold produced. Tonnes processed increased 6.9% quarter-on-quarter while mined and processed gold grades remained elevated at 14.00 gpt.

The Company is reaffirming its increased 2024 gold production guidance range of 60,000 to 65,000 ounces. While mined and processed gold grades are projected to remain above long-term block model grades in H2 2024, they are expected to decrease relative to Q2 2024, leading to slightly lower production and higher unit costs in H2 2024 compared to H1 2024. However, due to exceptional year-to-date operating and cost performance, full-year unit operating costs are now projected to be lower than originally budgeted. As a result, the Company is reducing its 2024 gold C1 cash cost guidance to $450 to $550 (from $550 to $650) per ounce of gold produced and its AISC guidance to $900 to $1,000 (from $1,050 to $1,150) per ounce of gold produced.

Exploration activities at the Xavantina Operations during the quarter continued to focus on testing the down plunge extension of the Santo Antônio vein as well as drill testing the Santo Antonio/Brás joining extension. Regional surface exploration efforts focused on identifying additional gold systems parallel to Xavantina mine system.

2024 GUIDANCE

The Company is reaffirming its consolidated copper production guidance of 59,000 to 72,000 tonnes in concentrate, with production expected to be weighted towards H2 2024 largely due to the projected ramp-up of production at the Tucumã Project. Contributions from the Tucumã Project, combined with significantly lower concentrate treatment and refining charges, as well as a more favorable USD to BRL exchange rate, are expected to result in lower consolidated copper C1 cash costs in H2 2024 compared to H1 2024. As a result, the Company is reaffirming its full-year consolidated copper C1 cash cost guidance range of $1.50 to $1.75 per pound of copper produced.

The Company is reaffirming its increased full-year gold production guidance range of 60,000 to 65,000 ounces. While slightly lower production is projected to result in higher unit costs in H2 2024 compared to H1 2024, the Company is lowering its 2024 gold cost guidance to reflect exceptional year-to-date unit cost performance. Full-year gold C1 cash cost guidance is now $450 to $550 (originally $550 to $650) per ounce of gold produced, and AISC guidance has been reduced to $900 to $1,000 (from $1,050 to $1,150) per ounce of gold produced.

2024 Production and Cost Guidance

The Company's cost guidance for 2024 assumes a foreign exchange rate of 5.00 BRL per USD, a gold price of $1,900 per ounce and a silver price of $23.00 per ounce.

Notes:

1.    Revenues from copper sales in Q2 2024 was $78.9 million (Q2 2023 - $83.9 million) on sale of 19.2 million lbs of copper (Q2 2023 - 25.6 million lbs) at an average realized price of $4.22 (Q2 2023 - $3.51) per lb. The decrease in copper revenues was primarily attributed to lower quantity sold as a result of lower grades mined, partially offset by higher average realized price.

Revenues from gold sales in Q2 2024 was $38.1 million (Q2 2023 - $21.0 million) on sale of 17,621 ounces of gold (Q2 2023 - 10,916 ounces) at an average realized price of $2,193 per ounce (Q2 2023 - $1,945 per ounce). The increase in gold revenues was attributable to both higher realized gold price and an increase in sales volume, as production and head grades both increased significantly compared to the same quarter of the prior year.

2.    Cost of sales for Q2 2024 from copper sales was $59.6 million (Q2 2023 - $56.2 million) which primarily comprised of $15.8 million (Q2 2023 - $16.1 million) in depreciation and depletion, $13.1 million (Q2 2023 - $12.7 million) in salaries and benefits, $10.1 million (Q2 2023 - $9.8 million) in materials and consumables, $7.8 million (Q2 2023 - $7.0 million) in contracted services, $7.7 million (Q2 2023 - $6.7 million) in maintenance costs, $2.6 million (Q2 2023 - $2.9 million) in utilities, $1.9 million (Q2 2023 - $2.3 million) in sales expenses, and $0.5 million increase (Q2 2023 - $1.6 million decrease) in changes in inventories. The increase in cost of sales in Q2 2024 as compared to Q2 2023 was primarily attributable to a 14% increase in tonnes processed and higher labour costs from wage and other benefit increases. Lower grades of ore processed also resulted in an increase in the cost per pound sold.

Cost of sales for Q2 2024 from gold sales was $14.2 million (Q2 2023 - $9.3 million) which primarily comprised of $6.0 million (Q2 2023 - $3.5 million) in depreciation and depletion, $2.5 million (Q2 2023 - $2.2 million) in salaries and benefits, $1.8 million (Q2 2023 - $1.5 million) in materials and consumables, $1.7 million (Q2 2023 - $1.5 million) in contracted services, $0.6 million (Q2 2023 - $0.5 million) in maintenance costs, and $0.6 million (Q2 2023 - $0.6 million) in utilities. The increase in cost of sales as compared to Q2 2023 was primarily due to a 61% increase in gold ounces sold, attributable to higher gold production as well as the sale of finished goods inventories from the previous quarter, resulting in higher depreciation and depletion and changes in inventories. These increases were more than offset by the increase on grades of ore mined which reduced the cost per ounce sold.

3.    General and administrative expenses for Q2 2024 was primarily comprised of $7.0 million (Q2 2023 - $8.3 million) in salaries and consulting fees, $2.2 million (Q2 2023 - $2.0 million) in office and administration expenses, $1.0 million (Q2 2023 - $1.4 million) in incentive payments, $0.7 million (Q2 2023 - $0.4 million) in accounting and legal costs, and $0.5 million (Q2 2023 - $1.0 million) in other costs. The decrease in general and administrative expenses was mainly attributed to reduction in consulting fees.

4.    In Q2 2024, the Company terminated the Fides option agreement, resulting in a write-down in exploration and evaluation assets of $10.7 million (Q2 2023 - nil).

5.    Finance expense for Q2 2024 was $4.6 million (Q2 2023 - $6.0 million) and is primarily comprised of other finance expense of $2.9 million (Q2 2023 - $0.4 million), accretion of deferred revenue of $0.6 million (Q2 2023 - $0.8 million), accretion of asset retirement obligations of $0.6 million (Q2 2023 - $0.7 million), lease interest of $0.5 million (Q2 2023 - $0.3 million), and interest on loans and borrowings of $— million (Q2 2023 - $3.9 million). Interest on loans and borrowings were net of $9.1 million (Q2 2023 - $3.2 million) in borrowing costs which were capitalized to projects in progress. The overall decrease in finance expense was attributable to an increase in capitalization of borrowing costs as a result of higher capital expenditures on construction projects as compared to the same quarter in the prior year, partially offset by a credit loss provision of $2.6 million recognized on a note receivable.

6.    Foreign exchange loss for Q2 2024 was $70.5 million (Q2 2023 - $15.1 million gain). This amount is primarily comprised of $54.9 million (Q2 2023 - $12.1 million gain) in foreign exchange loss on USD denominated debt at MCSA for which the functional currency is the BRL, $16.1 million (Q2 2023 - $2.1 million gain) of unrealized foreign exchange loss on derivative contracts, and $1.0 million (Q2 2023 - $2.8 million gain) realized foreign exchange loss on derivative contracts, partially offset by other foreign exchange gains of $1.5 million (Q2 2023 - $1.9 million losses). The unrealized foreign exchange loss on USD denominated debt and on derivative contracts was a result of the 10.14% weakening of the BRL against the USD during the period.

7.    In Q2 2024, the Company recognized $8.3 million in income tax recovery (Q2 2023 - tax expense of $5.8 million). The change in income tax was primarily a result of a loss before taxes due to unrealized foreign exchange losses as compared to income before taxes in the same quarter of the prior year.

Ero Copper Corp. June 30, 2024 MD&A | Page 10

8.    The foreign currency translation loss is a result of a fluctuation of the BRL against the USD during Q2 2024, which weakened from approximately 5.00 BRL per US dollar at the beginning of Q2 2024 to approximately 5.56 BRL per US dollar by the end of the quarter, when translating the net assets of the Company’s Brazilian subsidiaries to USD for presentation in the Company’s condensed consolidated interim financial statements.

Notes:

1.    Revenues from copper sales in YTD 2024 amounted to $152.8 million (YTD 2023 - $161.2 million), reflecting the sale of 40.1 million lbs of copper compared to 46.5 million lbs of copper for YTD 2023. The decrease in revenues was primarily due to 14% lower copper sales resulting from lower copper grades, partially offset by a 7% higher realized copper price.

Revenues from gold sales in YTD 2024 amounted to $70.1 million (YTD 2023 - $44.7 million), reflecting the sale of 34,474 ounces of gold at a realized price of $2,060 per ounce, compared to 24,013 ounces of gold sold at a realized price of $1,881 per ounce in YTD 2023. The increase in revenues was driven by higher sales volume and improved gold prices compared to the prior year.

2.    Cost of sales for YTD 2024 from copper sales was $121.2 million (YTD 2023 - $106.8 million) which primarily consisted of $33.4 million (YTD 2023 - $28.6 million) in depreciation and depletion, $26.3 million (YTD 2023 - $23.9 million) in salaries and benefits, $18.8 million (YTD 2023 - $18.3 million) in materials and consumables, $14.3 million (YTD 2023 - $13.0 million) in contracted services, $14.4 million (YTD 2023 - $13.2 million) in maintenance costs, $5.7 million (YTD 2023 - $5.6 million) in utilities, and $3.7 million (YTD 2023 - $4.2 million) in sales expenses. The increase in cost of sales was primarily attributed to a 12% increase in tonnes processed, higher depreciation and depletion from an expanded depletable asset base, and increased labour costs from wage and other benefit increases.

Cost of sales for YTD 2024 from gold sales was $27.2 million (YTD 2023- $19.5 million) which primarily comprised of $11.3 million (YTD 2023 - $7.4 million) in depreciation and depletion, $5.1 million (YTD 2023 - $4.3 million) in salaries and benefits, $3.5 million (YTD 2023 - $3.0 million) in materials and consumables, $3.7 million (YTD 2023 - $2.8 million) in contracted services, $1.2 million (YTD 2023 - $1.1 million) in utilities, and $1.2 million (YTD 2023 - $0.9 million) in maintenance costs. The increase in cost of sales was mainly attributed to 44% increase in gold sales, accompanied with higher depreciation and depletion from increased sales and an expanded depreciable asset base.

3.    General and administrative expenses for YTD 2024 was primarily comprised of $13.0 million (YTD 2023 - $15.4 million) with respect to salaries and consulting fees, $4.5 million (YTD 2023 - $4.2 million) in office and administrative expenses, $2.7 million (YTD 2023 - $2.8 million) in incentive payments, $1.1 million (YTD 2023 - $1.9 million) in other general and administrative expenses, and $1.1 million (YTD 2023 - $1.0 million) in accounting and legal fees. The decrease in general and administrative expenses in YTD 2024 was primarily attributable to reduction in consulting fees.

4.    In YTD 2024, the Company terminated the Fides option agreement, resulting in a write-down in exploration and evaluation assets of $10.7 million (YTD 2023 - nil).

5.    Finance expense for YTD 2024 was $9.2 million (YTD 2023 - $12.5 million) and was primarily comprised of other finance expense of $5.7 million (YTD 2023 - $0.6 million), accretion of deferred revenue of $1.3 million (YTD 2023 - $1.6 million), accretion of the asset retirement obligations of $1.2 million (YTD 2023 - $1.3 million), lease interest of $0.9 million (YTD 2023 - $0.6 million), , and $— million (YTD 2023 - $8.4 million) from interest on loans and borrowings (net of capitalization of borrowing costs). During YTD 2024, $16.5 million (YTD 2023 - $5.6 million) in interest was capitalized to projects in progress. The overall decrease in finance expense was primarily attributable to higher interest capitalized as a result of capital expenditures incurred on various qualifying projects, partially offset by an increased interest on new loans and borrowings.

6.    Foreign exchange loss for YTD 2024 was $89.5 million (YTD 2023 - $23.7 million gain). This amount was primarily comprised of a foreign exchange loss of $67.7 million (YTD 2023 - $17.5 million gain) on USD denominated debt in MCSA, for which the functional currency is the BRL. In addition, the Company recognized a foreign exchange loss on unrealized derivative contracts of $25.4 million (YTD 2023 - $5.3 million gain), partially offset by realized foreign exchange gain on derivative contracts of $1.1 million (YTD 2023 - $3.8 million gain) and other foreign exchange gains of $2.5 million (YTD 2023 - $2.8 million losses). The fluctuation in foreign exchange gains/losses were primarily a result of increased volatility of the USD/BRL foreign exchange rates, which weakened 12.9% during YTD 2024.

7.    In YTD 2024, the Company recognized an $10.1 million income tax recovery (YTD 2023 - $10.4 million expense), The change was primarily a result of a loss in income before income taxes due to unrealized foreign exchange.

8.    The foreign currency translation loss is a result of fluctuations of the BRL against the USD during YTD 2024 when translating the net assets of the Company’s Brazilian subsidiaries to USD for presentation in the Company’s condensed consolidated interim financial statements.

Notes:

1.During Q2 2024, the Company recognized net loss of $53.4 million compared to net loss of $6.8 million in the preceding quarter. The increase in loss was primarily attributable to foreign exchange losses of $70.5 million compared to $19.0 million in the preceding quarter. The change in foreign exchange gain or loss was primarily driven by volatility of the Brazilian Real against the US Dollar during the respective periods. In addition, during the quarter, the Company terminated the Fides option agreement, resulting in a write-down in exploration and evaluation assets of $10.7 million.

2.During Q1 2024, the Company recognized net loss of $6.8 million compared to net income of $37.1 million in the preceding quarter. The decrease in income was primarily attributable to foreign exchange losses of $19.0 million compared to foreign exchange gains of $24.9 million in the preceding quarter. The change in foreign exchange gain or loss was primarily driven by volatility of the Brazilian Real against the US Dollar during the respective periods.

3.During Q4 2023, the Company recognized net income of $37.1 million compared to $2.8 million in the preceding quarter. The increase was primarily attributable to foreign exchange gains of $24.9 million compared to foreign exchange losses of $13.9 million in the preceding quarter. The change in foreign exchange gain or loss was primarily driven by volatility of the Brazilian Real against the US Dollar during the respective periods.

4.During Q3 2023, the Company recognized net income of $2.8 million compared to $29.9 million in the preceding quarter. The decrease was primarily attributable to foreign exchange losses of $13.9 million compared to foreign exchange gain of $15.1 million in the preceding quarter.

5.During Q2 2023, the Company recognized net income of $29.9 million compared to $24.5 million in the preceding quarter. The increase was primarily attributable to an increase in foreign exchange gain and the recognition of an unrealized gain in copper derivative contracts.

6.During Q1 2023, the Company recognized net income of $24.5 million compared to $22.5 million in the preceding quarter. The increase was primarily attributable to an increase in foreign exchange gain, a reduction in general and
Ero Copper Corp. June 30, 2024 MD&A | Page 13

administrative expenses, and a reduction in finance expense. In the prior quarter, the Company recognized a $3.3 million expected credit loss provision.

7.During Q4 2022, the Company recognized net income of $22.5 million compared to $4.0 million in the preceding quarter. The increase was primarily attributable to a $29.9 million increase in gross profit as a result of 13% increase in copper production, partially offset by higher share-based payment expenses and a $3.3 million expected credit loss provision recognized in relation to payment arrangement with PMA.

8.During Q3 2022, the Company recognized net income of $4.0 million compared to $24.1 million in the preceding quarter. The decrease was primarily attributable to a $27.9 million decrease in gross profit as a result of 12% lower production, reduced copper and gold realized prices, and provisional pricing adjustments on copper concentrate sold in the prior quarter.

LIQUIDITY, CAPITAL RESOURCES, AND CONTRACTUAL OBLIGATIONS

Liquidity

As at June 30, 2024, the Company had cash and cash equivalents of $44.8 million and available liquidity of $169.8 million.

Ero Copper Corp. June 30, 2024 MD&A | Page 14


As at June 30, 2024, the Company had working capital deficit of $57.6 million.


Capital Resources

At June 30, 2024, the Company had available liquidity of $169.8 million, including $44.8 million in cash and cash equivalents, $100.0 million of undrawn availability under its senior secured revolving credit facility and $25.0 million of undrawn availability under its copper repayment facility.

In May 2024, to support the commencement of production and associated working capital needs at the Tucumã Project, the Company entered into a $50.0 million non-priced copper prepayment facility, structured by the Bank of Montreal and with participation by CIBC Capital Markets. This facility will be repaid over 27 equal monthly installments, beginning in October 2024, through the delivery of 272 tonnes of copper each month. Each monthly delivery's value will be determined based on prevailing market copper prices at the time of delivery. Should the value of any delivery exceed the amount of the monthly installment payment of $2.1 million, the excess value will be repaid to the Company. The copper to be delivered by the Company will be in the form of LME Copper Warrants. Through the end of 2024, the Company has the option to increase the size of the non-priced copper prepayment facility from $50.0 million to $75.0 million.

The Company’s primary sources of capital are comprised of cash from operations, and cash and cash equivalents on hand. The Company continuously monitors its liquidity position and capital structure and, based on changes in operations and economic conditions, may adjust such structure by issuing new common shares or new debt as necessary. Taking into consideration expected cash flow from existing operations and available liquidity, management believes that the Company has sufficient capital to fund its planned operations and activities, including the capital expenditures to complete the Tucumã Project, and other initiatives, for the foreseeable future.

In 2023, the senior credit facility was amended to increase its limit from $75.0 million to $150.0 million with maturity extended from March 2025 to December 2026 ("Amended Senior Credit Facility"). The Amended Senior Credit Facility bears interest on a sliding scale of SOFR plus an applicable margin of 2.00% to 4.50% depending on the Company's consolidated leverage ratio. Commitment fees for the undrawn portion of the Amended Senior Credit Facility is also based on a sliding scale ranging from 0.45% to 1.01%.

In relation to its loans and borrowings, the Company is required to comply with certain financial covenants. As of the date of the condensed consolidated interim financial statements, the Company is in compliance with these covenants. The loan agreements also contain covenants that could restrict the ability of the Company and its subsidiaries, MCSA, Ero Gold, and NX Gold, to, among other things, incur additional indebtedness needed to fund its respective operations, pay dividends or make other distributions, make investments, create liens, sell or transfer assets or enter into transactions with affiliates. There are no other restrictions or externally imposed capital requirements of the Company.

Contractual Obligations and Commitments

The Company has a precious metals purchase agreement with RGLD Gold AG ("Royal Gold"), a wholly-owned subsidiary of Royal Gold, Inc., whereby the Company is obligated to sell a portion of its gold production from the Xavantina Operations at contract prices.

Refer to the "Liquidity Risk" section for further information on the Company's contractual obligations and commitments.

MANAGEMENT OF RISKS AND UNCERTAINTIES

The Company thoroughly examines the various financial instruments and risks to which it is exposed and assesses the impact and likelihood of those risks. These risks may include credit risk, liquidity risk, currency risk, commodity price risk and interest rate risk. Where material, these risks are reviewed and monitored by the Board.

Credit risk

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations and arises principally from the Company’s receivables from customers. The carrying amount of the financial assets below represents the maximum credit risk exposure as at June 30, 2024 and December 31, 2023:

June 30, 2024December 31, 2023
Cash and cash equivalents44,773 $111,738 
Accounts receivable16,422 5,710 
Derivatives— 11,254 
Note receivable11,590 17,413 
Deposits and other assets10,123 9,484 
$82,908 $155,599 

The Company invests cash and cash equivalents and short-term investments with financial institutions that are financially sound based on their credit rating.

The Company’s exposure to credit risk associated with accounts receivable is influenced mainly by the individual characteristics of each customer.

In November 30, 2022, Paranapanema S/A ("PMA"), one of the Company's customers in Brazil, filed for bankruptcy protection. According to PMA, the action was attributed to working capital challenges following an operational halt at one of their facilities. Progress was noted in August 2023 when PMA and its creditors agreed on a judicial recovery plan, which subsequently received approval from the judicial recovery court in November 2023. As a preferred supplier to PMA, the Company has entered into a note receivable arrangement with PMA. The arrangement is excluded from the judicial recovery process and provides the Company with certain judicial guarantees. According to the note receivable arrangement, repayment was structured over 24 monthly installments beginning in March 2024, with an annual interest rate equivalent to Brazil's CDI rate of approximately 11.65%.
Ero Copper Corp. June 30, 2024 MD&A | Page 16


At June 30, 2024, the gross amount of accounts and note receivable from PMA was $23.0 million (December 31, 2023 - $25.2 million). PMA continued to miss its installment due in 2024, and is currently in default of the agreement. Accordingly, the note receivable is considered credit impaired, and the Company increased the expected credit loss provision by $2.6 million and $4.5 million in the three and six months ended June 30, 2024, respectively. After adjusting for credit loss provision and present value discount of $10.9 million (December 31, 2023 - $7.7 million), the amortized cost of the note receivable at June 30, 2024 was $11.6 million (December 31, 2023 - $17.4 million), of which $5.5 million (December 31, 2023 - $8.3 million) was classified as current and $6.1 million (December 31, 2023 - $9.1 million) as non-current.


Liquidity risk

Liquidity risk is the risk associated with the difficulties that the Company may have meeting the obligations associated with financial liabilities that are settled with cash payments or with another financial asset. The Company's approach to liquidity management is to ensure as much as possible that sufficient liquidity exists to meet their maturity obligations on the expiration dates, under normal and stressful conditions, without causing unacceptable losses or with risk of undermining the normal operation of the Company.

The table below shows the Company's maturity of non-derivative financial liabilities on June 30, 2024:

Total$654,357 $843,005 $172,236 $190,318 $480,008 $443 

As at June 30, 2024, the Company has capital commitments, which is net of advances to suppliers, of $76.3 million through contracts and purchase orders which are expected to be incurred over a six-year period. In the normal course of operations, the Company may also enter into long-term contracts which can be cancelled with certain agreed customary notice periods without material penalties.

The Company also has a derivative financial liability for foreign exchange collar contracts whose notional amounts and maturity information are disclosed below under foreign exchange currency risk.

Foreign exchange currency risk

The Company’s subsidiaries in Brazil are exposed to exchange risks primarily related to the US dollar. In order to minimize currency mismatches, the Company monitors its cash flow projections considering future sales expectations indexed to US dollar variation in relation to the cash requirement to settle the existing financings.
Ero Copper Corp. June 30, 2024 MD&A | Page 17


The Company's exposure to foreign exchange currency risk at June 30, 2024 relates to $67.9 million (December 31, 2023 – $17.2 million) in loans and borrowings of MCSA denominated in US dollars and Euros. In addition, the Company is also exposed to foreign exchange currency risk at June 30, 2024 on $463.7 million of intercompany loan balances (December 31, 2023 - $342.2 million) which have contractual repayment terms. Strengthening (weakening) in the Brazilian Real against the US dollar at June 30, 2024 by 10% and 20%, would have decreased (increased) pre-tax net loss by $53.1 million and $106.2 million, respectively. This analysis is based on the foreign currency exchange variation rate that the Company considered to be reasonably possible at the end of the period and excluding the impact of the derivatives below. The analysis assumes that all other variables, especially interest rates, are held constant.

The Company may use certain foreign exchange derivatives, including collars and forward contracts, to manage its foreign exchange risks. A summary of the Company's foreign exchange derivatives at June 30, 2024 is summarized as follows:


PurposeNotional AmountDenominationWeighted average floorWeighted average cap / forward priceMaturities
Operational costs$247.5 millionUSD/BRL5.085.64Jul 2024 - Dec 2025
Capital expenditures$39.0 millionUSD/BRL5.115.22Jul 2024 - Dec 2024
Total$286.5 millionUSD/BRL5.035.38Jul 2024 - Dec 2025

The aggregate fair value of the Company's foreign exchange derivatives was a net asset of $13.8 million (December 31, 2023 - asset of $11.3 million). The fair values of foreign exchange contracts were determined based on option pricing models, forward foreign exchange rates, and information provided by the counter party.

The change in fair value of foreign exchange derivatives was a loss of $16.1 million and a loss of $25.4 million for the three and six months ended June 30, 2024 (a gain of $2.1 million and a $5.3 million for the three and six months ended June 30, 2023), respectively, which have been recognized in foreign exchange (loss) gain.

In addition, during the three and six months ended June 30, 2024, the Company recognized a realized gain of $1.0 million and a $1.1 million (realized gain of $2.8 million and $3.8 million for the three and six months ended June 30, 2023), respectively, related to the settlement of foreign exchange derivatives.

Interest rate risk

The Company is principally exposed to the variation in interest rates on loans and borrowings with variable rates of interest. Management reduces interest rate risk exposure by entering into loans and borrowings with fixed rates of interest or by entering into derivative instruments that fix the ultimate interest rate paid.

The Company is principally exposed to interest rate risk through its Senior Credit Facility and Brazilian Real denominated bank loans. Based on the Company’s net exposure at June 30, 2024, a 1% change in the variable rates would not materially impact its pre-tax annual net income.
Ero Copper Corp. June 30, 2024 MD&A | Page 18


Price risk

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage commodity price risks.

At June 30, 2024, the Company had provisionally priced sales that are exposed to commodity price changes. Based on the Company’s net exposure at June 30, 2024, a 10% change in the price of copper would have changed $2.0 million.

During the three and six months ended June 30, 2024, the Company recognized an unrealized loss of $0.4 million and an unrealized loss of $0.4 million (unrealized gain of $2.4 million and unrealized gain of $2.7 million for the three and six months ended June 30, 2023), respectively, on its copper collar contract. At June 30, 2024, the Company does not have any outstanding copper collar contracts.

During the three and six months ended June 30, 2024, the Company also recognized a realized loss of $1.8 million and a realized loss of $1.8 million, respectively, in relation to its copper collar contract in other income or loss (nil and $1.8 million realized loss for three and six months ended June 30, 2023).

ACCOUNTING POLICIES, JUDGMENTS AND ESTIMATES

Critical Accounting Judgments and Estimates

The preparation of condensed consolidated interim financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions about future events that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Although these estimates are based on management’s best knowledge of the amount, events or actions, actual results may differ from these estimates.

The Company’s material accounting policies and accounting estimates are contained in the Company’s consolidated financial statements for the year ended December 31, 2023 and condensed consolidated interim financial statements for the three and six months ended June 30, 2024. Judgements have been made in the determination of the functional currency of the Company and its subsidiaries and in the assessment of the probability of cash outflow related to legal claims and contingent liabilities. Certain of accounting policies, such as derivative instruments, deferred revenue, carrying amounts of mineral properties and associated mine closure and reclamation costs, provision for mine closure and reclamation costs, income tax including tax uncertainties, and expected credit losses involve critical accounting estimates. Certain of these estimates are dependent on mineral reserves and resource estimates. Changes in estimates of mineral reserves and resources could impact depreciation and depletion rates, asset carrying amounts and the provisions for mine closure and reclamation costs. The Company estimates its mineral reserves and resources based on information compiled by competent individuals. Estimates of mineral reserves and resources are used in the calculation of depreciation, depletion and determination, when applicable, of the recoverable amount of CGUs, and for forecasting the timing of reclamation and closure cost expenditures. There are numerous uncertainties inherent in estimating mineral reserves, and assumptions that are valid at the time of estimation may change significantly when new information becomes available. Changes in the estimation methodology, forecasted prices of commodities, exchange rates, production costs or recovery rates may change the economic status of mineral reserves and may, ultimately, result in changes in the mineral reserves.

Management continuously reviews its estimates, judgments and assumptions on an ongoing basis using the most current information available. Revisions to estimates are recognized prospectively.

ALTERNATIVE PERFORMANCE (NON-IFRS) MEASURES

The Company utilizes certain alternative performance (non-IFRS) measures to monitor its performance, including copper C1 cash cost, copper C1 cash cost including foreign exchange hedges, realized copper price, gold C1 cash cost, gold AISC, realized gold price, EBITDA, adjusted EBITDA, adjusted net income attributable to owners of the Company, adjusted net income per share, net (cash) debt, working capital and available liquidity. These performance measures have no standardized meaning prescribed within generally accepted accounting principles under IFRS and, therefore, amounts presented may not be comparable to similar measures presented by other mining companies. These non-IFRS measures are intended to provide supplemental information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The tables below provide reconciliations of these non-IFRS measures to the most directly comparable IFRS measures as contained in the Company’s financial statements.

Unless otherwise noted, the non-IFRS measures presented below have been calculated on a consistent basis for the periods presented.

Copper C1 Cash Cost and Copper C1 Cash Cost including Foreign Exchange Hedges

Copper C1 cash cost and copper C1 cash cost including foreign exchange hedges are non-IFRS performance measures used by the Company to manage and evaluate the performance of its copper mining operations.

Copper C1 cash cost is calculated as C1 cash costs divided by total pounds of copper produced during the period. C1 cash costs comprise the total cost of production, including expenses related to transportation, and treatment and refining charges. These costs are net of by-product credits, incentive payments and certain tax credits associated with sales invoiced to the Company's Brazilian customer.

Copper C1 cash cost including foreign exchange hedges is calculated as C1 cash costs, adjusted for realized gains or losses from its operational foreign exchange hedges, divided by total pounds of copper produced during the period. Although the Company does not apply hedge accounting in its consolidated financial statements and recognizes these contracts at fair value through profit or loss,
Ero Copper Corp. June 30, 2024 MD&A | Page 22

the Company believes it appropriate to present cash costs including the impact of realized gains and losses as these contracts were entered into to mitigate the impact of changes in exchange rates.

While copper C1 cash cost is widely reported in the mining industry as a performance benchmark, it does not have a standardized meaning and is disclosed as a supplement to IFRS measures.

The following table provides a reconciliation of copper C1 cash cost to cost of production, its most directly comparable IFRS measure.

Gold C1 Cash Cost and Gold AISC

Gold C1 cash cost is a non-IFRS performance measure used by the Company to manage and evaluate the operating performance of its gold mining segment and is calculated as C1 cash costs divided by total ounces of gold produced during the period. C1 cash cost includes total cost of production, net of by-product credits and incentive payments. Gold C1 cash cost is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in supplemental to IFRS measures.

Gold AISC is an extension of gold C1 cash cost discussed above and is also a key performance measure used by management to evaluate operating performance of its gold mining segment. Gold AISC is calculated as AISC divided by total ounces of gold produced during the period. AISC includes C1 cash costs, site general and administrative costs, accretion of mine closure and rehabilitation provision, sustaining capital expenditures, sustaining leases, and royalties and production taxes. Gold AISC is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in supplement to IFRS measures.

Earnings before interest, taxes, depreciation, and amortization (“EBITDA”) and Adjusted EBITDA

EBITDA and adjusted EBITDA are non-IFRS performance measures used by management to evaluate its debt service capacity and performance of its operations. EBITDA represents earnings before finance expense, finance income, income taxes, depreciation and amortization. Adjusted EBITDA is EBITDA before the pre-tax effect of adjustments for non-cash and/or non-recurring items required in determination of EBITDA for covenant calculation purposes.

Adjusted net income attributable to owners of the Company and Adjusted net income per share attributable to owners of the Company

“Adjusted net income attributable to owners of the Company” is net income attributed to shareholders as reported, adjusted for certain types of transactions that, in management's judgment, are not indicative of our normal operating activities or do not necessarily occur on a recurring basis. “Adjusted net income per share attributable to owners of the Company” (“Adjusted EPS”) is calculated as "adjusted net income attributable to owners of the Company" divided by weighted average number of outstanding common shares in the period. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, the Company and certain investor and analysts use these supplemental non-IFRS performance measures to evaluate the normalized performance of the Company. The presentation of Adjusted EPS is not meant to substitute the net income (loss) per share attributable to owners of the Company (“EPS”) presented in accordance with IFRS, but rather it should be evaluated in conjunction with such IFRS measures.
The following table provides a reconciliation of Adjusted net income attributable to owners of the Company and Adjusted EPS to net income attributable to the owners of the Company, its most directly comparable IFRS measure.

Net Debt

Net debt is a performance measure used by the Company to assess its financial position and ability to pay down its debt. Net debt is determined based on cash and cash equivalents, short-term investments, net of loans and borrowings as reported in the Company’s condensed consolidated interim financial statements. The following table provides a calculation of net (cash) debt based on amounts presented in the Company’s condensed consolidated interim financial statements as at the periods presented.

Working Capital and Available Liquidity

Working capital is calculated as current assets less current liabilities as reported in the Company’s condensed consolidated interim financial statements. The Company uses working capital as a measure of the Company’s short-term financial health and ability to meet its current obligations using its current assets. Available liquidity is calculated as the sum of cash and cash equivalents, short-term investments and the undrawn amount available on its revolving credit facilities. The Company uses this information to evaluate the liquid assets available. The following table provides a calculation for these based on amounts presented in the Company’s condensed consolidated interim financial statements as at the periods presented.

DISCLOSURE CONTROLS AND PROCEDURES AND INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company’s management, with the participation of the CEO and CFO, is responsible for establishing and maintaining adequate disclosure controls and procedures (“DC&P”) and internal control over financial reporting (“ICFR”) using Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") as its internal control framework.

The Company’s DC&P are designed to provide reasonable assurance that material information related to the Company is identified and communicated on a timely basis.

The Company’s ICFR is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS. Any system of ICFR, no matter how well designed, has inherent limitations and cannot provide absolute assurance that all misstatements and instances of fraud, if any, within the Company have been prevented or detected. The Company’s ICFR is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS.

Ero Copper Corp. June 30, 2024 MD&A | Page 30

There were no changes in the Company’s DC&P and ICFR that materially affected, or are reasonably likely to materially affect, ICFR during the three and six months ended June 30, 2024.

Cautionary Note Regarding Forward-Looking Statements

This MD&A contains “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 and “forward-looking information” within the meaning of applicable Canadian securities legislation (collectively, “forward-looking statements”). Forward-looking statements include statements that use forward-looking terminology such as “may”, “could”, “would”, “will”, “should”, “intend”, “target”, “plan”, “expect”, “budget”, “estimate”, “forecast”, “schedule”, “anticipate”, “believe”, “continue”, “potential”, “view” or the negative or grammatical variation thereof or other variations thereof or comparable terminology. Forward-looking statements may include, but are not limited to, statements with respect to the Company’s production, operating cost and capital expenditure guidance; targeting additional mineral resources and expansion of deposits; capital and operating cost estimates and economic analyses (including cash flow projections), including those from the Caraíba Operations Technical Report, the Xavantina Operations Technical Report and the Tucumã Project Technical Report; the Company’s expectations, strategies and plans for the Caraíba Operations, the Xavantina Operations and the Tucumã Project, including the Company’s planned exploration, development, construction and production activities; the results of future exploration and drilling; estimated completion dates for certain milestones; successfully adding or upgrading mineral resources and successfully developing new deposits; the costs and timing of future exploration, development and construction including but not limited to the Deepening Extension Project at the Caraíba Operations and the Tucumã Project; the timing and amount of future production at the Caraíba Operations, the Xavantina Operations and the Tucumã Project; the Company's expectations regarding planned capital expenditures for the Tucumã Project, the Deepening Extension Project and/or the Caraíba Mill expansion project falling within contingency levels; expectations regarding the Company's ability to manage risks related to future copper price fluctuations and volatility; future financial or operating performance and condition of the Company and its business, operations and properties, including expectations regarding liquidity, capital structure, competitive position and payment of dividends; expectations regarding future currency exchange rates; and any other statement that may predict, forecast, indicate or imply future plans, intentions, levels of activity, results, performance or achievements.

Forward-looking statements are subject to a variety of known and unknown risks, uncertainties and other factors that could cause actual results, actions, events, conditions, performance or achievements to materially differ from those expressed or implied by the forward-looking statements, including, without limitation, risks discussed in this MD&A and in the AIF under the heading “Risk Factors”. The risks discussed in this MD&A and in the AIF are not exhaustive of the factors that may affect any of the Company’s forward-looking statements. Although the Company has attempted to identify important factors that could cause actual results, actions, events, conditions, performance or achievements to differ materially from those contained in forward-looking statements, there may be other factors that cause results, actions, events, conditions, performance or achievements to differ from those anticipated, estimated or intended.

Forward-looking statements are not a guarantee of future performance. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Forward-looking statements involve statements about the future and are inherently uncertain, and the Company’s actual results, achievements or other future events or conditions may differ materially from those reflected in the forward-looking statements due to a variety of risks, uncertainties and other factors, including, without limitation, those referred to herein and in the AIF under the heading “Risk Factors”.

Ero Copper Corp. June 30, 2024 MD&A | Page 32

The Company’s forward-looking statements are based on the assumptions, beliefs, expectations and opinions of management on the date the statements are made, many of which may be difficult to predict and beyond the Company’s control. In connection with the forward-looking statements contained in this MD&A and in the AIF, the Company has made certain assumptions about, among other things: favourable equity and debt capital markets; the ability to raise any necessary additional capital on reasonable terms to advance the production, development and exploration of the Company’s properties and assets; future prices of copper, gold and other metal prices; the timing and results of exploration and drilling programs; the accuracy of any mineral reserve and mineral resource estimates; the geology of the Caraíba Operations, the Xavantina Operations and the Tucumã Project being as described in the respective technical report for each property; production costs; the accuracy of budgeted exploration, development and construction costs and expenditures; the price of other commodities such as fuel; future currency exchange rates and interest rates; operating conditions being favourable such that the Company is able to operate in a safe, efficient and effective manner; work force continuing to remain healthy in the face of prevailing epidemics, pandemics or other health risks (including COVID-19), political and regulatory stability; the receipt of governmental, regulatory and third party approvals, licenses and permits on favourable terms; obtaining required renewals for existing approvals, licenses and permits on favourable terms; requirements under applicable laws; sustained labour stability; stability in financial and capital goods markets; availability of equipment; positive relations with local groups and the Company’s ability to meet its obligations under its agreements with such groups; and satisfying the terms and conditions of the Company’s current loan arrangements. Although the Company believes that the assumptions inherent in forward-looking statements are reasonable as of the date of this MD&A, these assumptions are subject to significant business, social, economic, political, regulatory, competitive and other risks and uncertainties, contingencies and other factors that could cause actual actions, events, conditions, results, performance or achievements to be materially different from those projected in the forward-looking statements. The Company cautions that the foregoing list of assumptions is not exhaustive. Other events or circumstances could cause actual results to differ materially from those estimated or projected and expressed in, or implied by, the forward-looking statements contained in this MD&A.

Forward-looking statements contained herein are made as of the date of this MD&A and the Company disclaims any obligation to update or revise any forward-looking statement, whether as a result of new information, future events or results or otherwise, except as and to the extent required by applicable securities laws.

Cautionary Notes Regarding Mineral Resource and Reserve Estimates

Unless otherwise indicated, all reserve and resource estimates included in this MD&A and the documents incorporated by reference herein have been prepared in accordance with Canadian NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission (the “SEC”), and reserve and resource information included herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, this MD&A and the documents incorporated by reference herein use the terms “measured resources,” “indicated resources” and “inferred resources” as defined in accordance with NI 43-101 and the CIM Standards.

Ero Copper Corp. June 30, 2024 MD&A | Page 33

Further to recent amendments, mineral property disclosure requirements in the United States (the “U.S. Rules”) are governed by subpart 1300 of Regulation S-K of the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”) which differ from the CIM Standards. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system (the “MJDS”), Ero is not required to provide disclosure on its mineral properties under the U.S. Rules and will continue to provide disclosure under NI 43-101 and the CIM Standards. If Ero ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the MJDS, then Ero will be subject to the U.S. Rules, which differ from the requirements of NI 43-101 and the CIM Standards.

Pursuant to the new U.S. Rules, the SEC recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources.” In addition, the definitions of “proven mineral reserves” and “probable mineral reserves” under the U.S. Rules are now “substantially similar” to the corresponding standards under NI 43-101. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that Ero reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms under the U.S. Rules are “substantially similar” to the standards under NI 43-101 and CIM Standards, there are differences in the definitions under the U.S. Rules and CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that Ero may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had Ero prepared the reserve or resource estimates under the standards adopted under the U.S. Rules.

1.    Nature of Operations

Ero Copper Corp. (“Ero" or the "Company") was incorporated on May 16, 2016 under the Business Corporations Act (British Columbia) and maintains its head office at Suite 1050, 625 Howe Street, Vancouver, British Columbia, Canada, V6C 2T6. The Company’s shares are publicly traded on the Toronto Stock Exchange and the New York Stock Exchange under the symbol “ERO”.

The Company’s primary asset is its 99.6% ownership interest in Mineração Caraíba S.A. (“MCSA”), held indirectly through its wholly-owned subsidiary, Ero Brasil Participaçoes Ltda. The Company also currently owns a 97.6% ownership interest in NX Gold S.A. (“NX Gold”) indirectly through its wholly-owned subsidiary, Ero Gold Corp. (“Ero Gold”).

MCSA is a Brazilian copper company which holds a 100% interest in the Caraíba Operations and the Tucumã Project. MCSA’s predominant activity is the production and sale of copper concentrate from the Caraíba Operations, located in Bahia, Brazil, with gold and silver produced and sold as by-products. The Tucumã Project, which is currently under construction with production of copper concentrate scheduled to commence in the second half of 2024, is located within the municipality of Tucumã in the southeastern part of the state of Pará, Brazil.

NX Gold is a Brazilian gold mining company which holds a 100% interest in the Xavantina Operations and is focused on the production and sale of gold as its main product and silver as its by-product. The Xavantina Operations are located approximately 18 kilometers west of the town of Nova Xavantina, in southeastern Mato Grosso State, Brazil.

2.    Basis of Preparation

(a)     Statement of Compliance

These condensed consolidated interim financial statements have been prepared in accordance with International Accounting Standards (“IAS”) 34, Interim Financial Reporting and follow the same accounting policies and methods of application as the Company’s most recent annual consolidated financial statements for the year ended December 31, 2023.

These condensed consolidated interim financial statements do not include all of the information required for full consolidated annual financial statements and should be read in conjunction with the consolidated financial statements of the Company as at and for the year ended December 31, 2023, prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).

These condensed consolidated interim financial statements were authorized for issue by the Board of Directors of the Company (the “Board”) on August 1, 2024.

(b)     Use of Estimates and Judgments

In preparing these condensed consolidated interim financial statements, management has made judgments, estimates and assumptions that affect the application of the Company’s accounting policies and the reported amounts of assets, liabilities, income and expense. Actual results may differ. Significant judgments made by management in applying the Company’s accounting policies and key sources of estimation uncertainty were the same as those applied in the most recent annual audited consolidated financial statements for the year ended December 31, 2023.

(c) New Accounting Policies, Standards and Interpretations

On January 1, 2024, the Company adopted the following amendments to accounting standards:

•In January 2020, the IASB issued Classification of Liabilities as Current or Non-current (Amendments to IAS 1) which amended IAS 1, Presentation of Financial Statements (“IAS 1”), to clarify the requirements for presenting liabilities in the statement of financial position. The amendments specify that the Company must have the right to defer settlement of a liability for at least 12 months after the reporting period for the liability to be classified as non-current. In addition, the amendments clarify that: (a) the Company’s right to defer settlement must exist at the end of the reporting period; (b) classification is unaffected by management’s intentions or expectations about whether the Company will exercise its right to defer settlement; (c) if the Company’s right to defer settlement is subject to the Company complying with specified conditions, the right exists at the end of the reporting period only if the Company complies with those conditions at the end of the reporting period, even if the lender does not test compliance until a later date; and (d) the term settlement includes the transfer of the Company’s own equity instruments to the counterparty that results in the extinguishment of the liability, except when the settlement of the liability with the Company transferring its own equity instruments is at the option of the counterparty and such option has been classified as an equity instrument, separate from the host liability.

•In October 2022, the IASB issued amendment Non-current Liabilities with Covenants to IAS 1 to clarify that covenants of loan arrangements which the Company must comply with only after the reporting date would not affect classification of a liability as current or non-current at the reporting date. The amendment also introduces additional disclosure requirements related to such covenants to include: (i) the nature of the covenants and the date by which the Company must comply with the covenants; (ii) the carrying amount of the related liabilities; and (iii) facts and circumstances, if any, that indicate that the Company may have difficulty complying with covenants.

The adoption of these amendments did not have a material impact on the Company's condensed consolidated interim financial statements.


(d)    Future Changes in Accounting Policies Not Yet Effective as of June 30, 2024

In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements ("IFRS 18") to replace IAS 1. IFRS 18 introduces two newly required subtotals on the face of the income statement, which includes operating profit and profit or loss before financing and income tax, and three new income statement classifications, which are operating, investing, and financing. In addition, IFRS 18 requires non-IFRS management performance measures that are subtotals of income and expenses to be disclosed on financial statement. IFRS 18 also provides additional guidance on principles of aggregation and disaggregation which apply to the primary financial statements and the notes. IFRS 18 will not affect the recognition and measurement of items in the financial statements, nor will it affect which items are classified in other comprehensive income and how these items are classified The standard is effective for reporting periods beginning on or after January 1, 2027, including for interim financial statements. Retrospective application is required and early application is permitted. The Company is currently assessing the effect of this new standard on our financial statements.


3.    Segment Disclosure

Operating segments are determined by the way information is reported and used by the Company's Chief Operating Decision Maker ("CODM") to review operating performance. The Company monitors the operating

    Notes to Financial Statements | Page 6

results of its operating segments independently for the purpose of making decisions about resource allocation and performance assessment.

For the three and six months ended June 30, 2024, the Company’s reporting segments include its two operating mines in Brazil, the Caraíba Operations and the Xavantina Operations, its development project, the Tucumã Project in Brazil, and its corporate head office in Canada. Significant information relating to the Company's reportable segments is summarized in the tables below:

7.    Exploration and Evaluation Assets

As at June 30, 2024, the Company had $16.7 million (2023 - $29.9 million) in exploration and evaluation assets, which include several property option agreements.

In June 2024, the Company terminated the Fides option agreement, resulting in a write-down of $10.7 million in exploration and evaluation assets for the three and six months ended June 30, 2024.

Additionally, in June 2024, the Company exercised the Edem option agreement to acquire a 399-hectare mineral concession in Mato Grosso State. This concession is located immediately east of and contiguous with the Xavantina Operations mining concession. Consequently, $2.2 million was reclassified from exploration and evaluation assets to mineral properties during the period.

(a)     Senior Notes

In February 2022, the Company issued $400 million aggregate principal amount of senior unsecured notes (the “Senior Notes”). The Company received net proceeds of $392.0 million after transaction costs of $8.0 million. The Senior Notes mature on February 15, 2030 and bear annual interest at 6.5%, payable semi-annually in February and August of each year.


    Notes to Financial Statements | Page 14

Notes to Condensed Consolidated Interim Financial Statements
(Unaudited, Tabular amounts in thousands of US Dollars, except share and per share amounts)
MCSA has provided a guarantee of the Senior Notes on a senior unsecured basis. The Senior Notes are direct, senior obligations of the Company and MCSA, and are not secured by any mortgage, pledge or charge.

The Senior Notes are subject to the following early redemption options by the Company:
•On or after February 15, 2025, the Company has the option, in whole or in part, to redeem the Senior Notes at a price ranging from 103.25% to 100% of the principal amount together with accrued and unpaid interest, if any, to the date of redemption, with the rate decreasing based on the length of time the Senior Notes are outstanding;
•Before February 15, 2025, the Company may redeem some or all of the Senior Notes at 100% of the principal amount plus a “make whole” premium, plus accrued and unpaid interest, if any, to the date of redemption; and
•At any time before February 15, 2025, the Company may redeem up to 40% of the original principal amount of the Senior Notes with the proceeds of certain equity offerings at a redemption price of 106.50% of the principal amount of the Senior Notes, together with accrued and unpaid interest, if any, to the date of redemption.

Upon the occurrence of specific kinds of changes of control triggering events, each holder of the Senior Notes will have the right to cause the Company to repurchase some or all of its Senior Notes at 101% of their principal amount, plus accrued and unpaid interest to, but not including, the repurchase date.

The Senior Notes are recognized as financial liabilities, net of unamortized transaction costs, and measured at amortized cost using an effective interest rate of 6.7%.

(b)    Senior Credit Facility

The Company has a Senior Revolving Credit Facility ("Senior Credit Facility") with a borrowing limit of $150.0 million which matures on December 2026. Amounts drawn on the Senior Credit Facility bear interest on a sliding scale at a rate of SOFR plus 2.00% to 4.50% depending on the Company’s consolidated leverage ratio. Commitment fees for any undrawn portion of the Senior Credit Facility are based on a sliding scale between 0.45% to 1.01%. As at June 30, 2024, the Senior Credit Facility bears an average interest rate of 8.97% on its drawn balance and a commitment fee of 0.79% on its undrawn balance.

During the six months ended June 30, 2024, the Company drew down a total of $70.0 million from its Senior Credit Facility, which included $45.0 million in the three months ended March 31, 2024 and $25.0 million in the three months ended June 30, 2024. Over the same period, the Company repaid $20.0 million of the principal amount of the facility. As a result, the net drawdown on the Senior Credit Facility for the six months ended June 30, 2024 was $50.0 million.

The Senior Credit Facility is secured by the shares of MCSA, NX Gold and Ero Gold. The Company is required to comply with certain financial covenants, which are required to be tested at each quarter end. These covenants include (a) a leverage ratio based on total indebtedness to rolling four quarters adjusted earnings before interest, taxes, depreciation and amortization ("Rolling EBITDA"); (b) a leverage ratio based on senior indebtedness to Rolling EBITDA; and (c) an interest coverage ratio based on Rolling EBITDA. The Senior Credit Facility provides for negative covenants customary for this type of facilities and permits additional equipment debt and finance leases of up to $50.0 million. As at June 30, 2024, the Company is in compliance with these financial covenants.

(c)    Copper Prepayment Facility

In May 2024, the Company entered into a non-priced copper prepayment facility with a bank syndicate. Under this facility, the Company received net proceeds of $49.6 million, representing gross proceeds of $50.0 million less transaction costs of $0.4 million. Through the end of 2024, the Company has the option to increase the size of the non-priced copper prepayment facility from $50.0 million to $75.0 million.

    Notes to Financial Statements | Page 15
Ero Copper Corp.
Notes to Condensed Consolidated Interim Financial Statements
(Unaudited, Tabular amounts in thousands of US Dollars, except share and per share amounts)

In exchange, the Company is obligated to repay the $50.0 million facility over 27 equal monthly installments, beginning in October 2024, through the delivery of a minimum of 272 tonnes of copper each month. Each monthly delivery's value will be determined based on prevailing market copper prices at the time of delivery. Should the value of any delivery exceed the amount of the monthly installment payment of $2.1 million, the excess value will be repaid to the Company. The copper to be delivered by the Company will be in the form of LME Copper Warrants.

As the contractual obligation of the facility will be settled in the form of financial assets, the facility is accounted for as a financial liability measured at amortized cost using the effective interest rate method. Transaction costs are included in the initial measurement of the liability and amortized over the term of the facility.

The facility is secured by the shares of MCSA, NX Gold and Ero Gold.


11. Deferred Revenue

In August 2021, the Company entered into a precious metals purchase agreement (the “NX Gold PMPA”) with RGLD Gold AG ("Royal Gold"), a wholly-owned subsidiary of Royal Gold, Inc., in relation to gold production from the Xavantina Operations. The Company received upfront cash consideration of $100.0 million for the purchase of 25% of an equivalent amount of gold to be produced from the Xavantina mine until 93,000 ounces of gold have been delivered and thereafter decreasing to 10% of gold produced over the remaining life of the mine. The contract will be settled by the Company delivering gold to Royal Gold. Royal Gold will make ongoing payments equal to 20% of the then prevailing spot gold price for each ounce of gold delivered until 49,000 ounces of gold have been delivered and 40% of the prevailing spot gold price for each ounce of gold delivered thereafter. Additional advances may be made by Royal Gold based on the Company achieving certain milestones as set out in the NX Gold PMPA.

The movements in deferred revenue during the six months ended June 30, 2024 are comprised of the following:

At June 30, 2024, a cumulative 37,651 ounces (December 31, 2023 - 29,260 ounces) of gold have been delivered under the NX Gold PMPA.
(2) Amortization of deferred revenue during the year ended December 31, 2023 was net of $2.5 million related to change in estimate attributed to advances received and change in life-of-mine production estimates.

As part of the NX Gold PMPA, the Company pledged its equity interest in Ero Gold and NX Gold to Royal Gold as collateral and provided unsecured limited recourse guarantees from Ero and NX Gold.

(b)     Performance Share Unit Plan

The Company has a performance share unit ("PSU") plan pursuant to which the Compensation Committee may grant PSUs to Eligible Persons of the Company or its subsidiaries. Each PSU entitles the holder thereof to receive one common share, its equivalent cash value, or a combination of both, on the redemption date at the discretion of the Compensation Committee.

The continuity of PSUs issued and outstanding is as follows:

Six Months Ended June 30,
20242023
Outstanding balance, beginning of period
967,921 881,788 
Issued 7,224 — 
Forfeited— (33,424)
Outstanding balance, end of period
975,145 848,364 

These PSUs will vest three years from the date of grant by the Compensation Committee and the number of PSUs that will vest may range from 0% to 200% of the number granted, subject to the satisfaction of certain market and non-market performance conditions. Each vested PSU entitles the holder thereof to receive on or about the applicable date of vesting of such share unit (i) one common share; (ii) a cash amount equal to the fair market value of one common share as at the applicable date of vesting; or (iii) a combination of (i) and (ii), as determined by the Compensation Committee in its sole discretion. The Company has elected to settle its PSUs using a combination of cash and common shares in the past. As such, based on its history of past settlements, PSUs are classified as liabilities.

For PSUs with non-market performance conditions, the fair value of the share units granted was initially recognized at the fair value using the share price at the date of grant, and subsequently remeasured at fair value on each balance sheet date. For PSUs with market performance conditions, the fair value was determined using a Geometric Brownian Motion model. As at June 30, 2024, the fair value of the PSU liability was $14.3 million (December 31, 2023 - $6.5 million) of which $7.3 million (December 31, 2023 - $3.9 million) was recognized in accounts payable and accrued liabilities and the remainder in other non-current liabilities.

(c) Deferred Share Unit Plan

The Deferred Share Unit ("DSU") plan was established by the Board as a component of compensation for the Company's independent directors. Pursuant to the DSU Plan, DSUs may only be settled by way of cash payment. A participant is not entitled to payment in respect of the DSUs until his or her death, retirement or removal from the Board.  The settlement amount of each DSU is based on the fair market value of a common share on the DSU redemption date multiplied by the number of DSUs being redeemed.

The continuity of DSUs issued and outstanding is as follows:

Six months ended June 30,
20242023
Outstanding balance, beginning of period
307,312 219,961
Issued 9,207 8,867 
Outstanding balance, end of period
316,519 228,828 

At June 30, 2024, DSU liabilities had a fair value of $6.8 million (December 31, 2023 - $4.9 million) which has been recognized in accounts payable and accrued liabilities.


(d) Restricted Share Unit Plan

The Company has a restricted share unit ("RSU") plan pursuant to which the Compensation Committee may grant share units to Eligible Persons of the Company or its subsidiaries. The fair value of these restricted share units is determined on the date of grant using the market price of the Company’s shares. Each RSU entitles the holder thereof to receive one common share, its equivalent cash value, or a combination of both, on the redemption date at the discretion of the Compensation Committee. The RSUs are equity classified based on the history of past settlements.

The continuity of RSUs issued and outstanding is as follows:

(1)    Adjustments on provisional sales include both pricing and quantity adjustments. Under the terms of the Company’s contract with its Brazilian domestic customer, sales are provisionally priced on the date of sale based on the previous month’s average copper price and subsequently settled based on the average copper price in the month of shipment. Provisionally priced sales to the Company's international customers are settled with a final sales price between zero to one month after shipment takes place and, therefore, are exposed to commodity price changes.
(2)    During the three and six months ended June 30, 2024, the Company delivered 3,836 and 8,391 ounces of gold, respectively (three and six months ended June 30, 2023 - 2,958 and 6,268 ounces of gold), under a precious metals purchase agreement with Royal Gold (note 11) for average cash consideration of $466 and $440 per ounce (three and six months ended June 30, 2023 - $400 and $385).

19.    Financial Instruments

Fair value

Fair values of financial assets and liabilities are determined based on available market information and valuation methodologies appropriate to each situation.


    Notes to Financial Statements | Page 23

(Unaudited, Tabular amounts in thousands of US Dollars, except share and per share amounts)

As at June 30, 2024, derivatives were measured at fair value based on Level 2 inputs.

The carrying values of cash and cash equivalents, short-term investments, accounts receivable, deposits, and accounts payable and accrued liabilities approximate their fair values due to their short terms to maturity or the discount rate used approximates to the contractual interest rate. At June 30, 2024, the carrying value of loans and borrowings, including accrued interest, was $526.8 million while the fair value is approximately $511.4 million. At June 30, 2024, the carrying value of notes receivable, including accrued interest, was $11.6 million which approximates its fair value.


Credit risk
    
Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations and arises principally from the Company’s receivables from customers. The carrying amount of the financial assets below represents the maximum credit risk exposure as at June 30, 2024 and December 31, 2023:

June 30, 2024December 31, 2023
Cash and cash equivalents$44,773 $111,738 
Accounts receivable16,422 5,710 
Derivatives— 11,254 
Note receivable11,590 17,413 
Deposits and other assets10,123 9,484 
$82,908 $155,599 

The Company invests cash and cash equivalents and short-term investments with financial institutions that are financially sound based on their credit rating.

The Company’s exposure to credit risk associated with accounts receivable is influenced mainly by the individual characteristics of each customer.

In November 2022, Paranapanema S/A ("PMA"), one of the Company's customers in Brazil, filed for bankruptcy protection. According to PMA, the action was attributed to working capital challenges following an operational halt at one of their facilities. Progress was noted in August 2023 when PMA and its creditors agreed on a judicial recovery plan, which subsequently received approval from the judicial recovery court in November 2023. As a preferred supplier to PMA, the Company has entered into a note receivable arrangement with PMA. The arrangement is excluded from the judicial recovery process and provides the Company with certain judicial guarantees. According to the note receivable arrangement, repayment was structured over 24 monthly installments beginning in March 2024, with an annual interest rate equivalent to Brazil's CDI rate of approximately 11.65%.

At June 30, 2024, the gross amount of accounts and note receivable from PMA was $23.0 million (December 31, 2023 - $25.2 million). PMA continued to miss its installment due in 2024, and is currently in default of the agreement. Accordingly, the note receivable is considered credit impaired, and the Company increased the expected credit loss provision by $2.6 million and $4.5 million in the three and six months ended June 30, 2024, respectively. After adjusting for credit loss provision and present value discount of $10.9 million (December 31, 2023 - $7.7 million), the amortized cost of the note receivable at June 30, 2024 was $11.6 million (December

(Unaudited, Tabular amounts in thousands of US Dollars, except share and per share amounts)
31, 2023 - $17.4 million), of which $5.5 million (December 31, 2023 - $8.3 million) was classified as current and $6.1 million (December 31, 2023 - $9.1 million) as non-current.

Liquidity risk

Liquidity risk is the risk associated with the difficulties that the Company may have meeting the obligations associated with financial liabilities that are settled with cash payments or with another financial asset. The Company's approach to liquidity management is to ensure as much as possible that sufficient liquidity exists to meet their maturity obligations on the expiration dates, under normal and stressful conditions, without causing unacceptable losses or with risk of undermining the normal operation of the Company.

The table below shows the Company's maturity of non-derivative financial liabilities on June 30, 2024:

The Company also has a derivative financial liability for foreign exchange collar contracts whose notional amounts and maturity information are disclosed below under foreign exchange currency risk.

Market risk

Market risk is the risk of loss that may arise from changes in market factors such as interest rates, foreign exchange rates, and commodity prices. The purpose of market risk management is to manage and control exposures to market risks, within acceptable parameters, while optimizing return.

The Company may use derivatives, including options, forwards and swap contracts, to manage market risks.

The Company's outstanding derivative instruments as of June 30, 2024 are as follows:

(i) Foreign exchange currency risk


    Notes to Financial Statements | Page 25

Notes to Condensed Consolidated Interim Financial Statements
(Unaudited, Tabular amounts in thousands of US Dollars, except share and per share amounts)
The Company’s subsidiaries in Brazil are exposed to exchange risks primarily related to the US dollar. In order to minimize currency mismatches, the Company monitors its cash flow projections considering future sales expectations indexed to US dollar variation in relation to the cash requirement to settle the existing financings.

The Company's exposure to foreign exchange currency risk at June 30, 2024 relates to $67.9 million (December 31, 2023 – $17.2 million) in loans and borrowings of MCSA denominated in US dollars and Euros. In addition, the Company is also exposed to foreign exchange currency risk at June 30, 2024 on $463.7 million of intercompany loan balances (December 31, 2023 - $342.2 million) which have contractual repayment terms. Strengthening (weakening) in the Brazilian Real against the US dollar at June 30, 2024 by 10% and 20%, would have decreased (increased) pre-tax net loss by $53.1 million and $106.2 million, respectively. This analysis is based on the foreign currency exchange variation rate that the Company considered to be reasonably possible at the end of the period and excluding the impact of the derivatives below. The analysis assumes that all other variables, especially interest rates, are held constant.

The Company may use certain foreign exchange derivatives, including collars and forward contracts, to manage its foreign exchange risks. At June 30, 2024, the aggregate fair value of the Company's foreign exchange derivatives was a net liability of $13.8 million (December 31, 2023 - asset of $11.3 million) of which $0.9 million is included in other non-current liabilities and the remainder in current portion of derivatives liabilities. The fair values of foreign exchange contracts were determined based on option pricing models, forward foreign exchange rates, and information provided by the counter party.

The change in fair value of foreign exchange derivatives was a loss of $16.1 million and a loss of $25.4 million for the three and six months ended June 30, 2024 (a gain of $2.1 million and a gain of $5.3 million for the three and six months ended June 30, 2023), respectively, which have been recognized in foreign exchange (loss) gain.

In addition, during the three and six months ended June 30, 2024, the Company recognized a realized loss of $1.0 million and a gain of $1.1 million (realized gain of $2.8 million and $3.8 million for the three and six months ended June 30, 2023), respectively, related to the settlement of foreign exchange derivatives.

(ii) Interest rate risk

The Company is principally exposed to the variation in interest rates on loans and borrowings with variable rates of interest. Management reduces interest rate risk exposure by entering into loans and borrowings with fixed rates of interest or by entering into derivative instruments that fix the ultimate interest rate paid.

The Company is principally exposed to interest rate risk through its Senior Credit Facility and Brazilian Real denominated bank loans. Based on the Company’s net exposure at June 30, 2024, a 1% change in the variable rates would not materially impact its pre-tax annual net income.

(iii) Price risk

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage commodity price risks.

At June 30, 2024, the Company had provisionally priced sales that are exposed to commodity price changes (note 14). Based on the Company’s net exposure at June 30, 2024, a 10% change in the price of copper would have changed pre-tax net loss by $2.0 million.

During the three and six months ended June 30, 2024, the Company recognized an unrealized loss of $0.4 million and an unrealized loss of $0.4 million (unrealized gain of $2.4 million and unrealized gain of $2.7 million for the three and six months ended June 30, 2023), respectively, on its copper collar contract. At June 30, 2024, the Company does not have any outstanding copper collar contracts.

(Unaudited, Tabular amounts in thousands of US Dollars, except share and per share amounts)
During the three and six months ended June 30, 2024, the Company also recognized a realized loss of $1.8 million and a realized loss of $1.8 million, respectively, in relation to its copper collar contract in other income or loss (nil and $1.8 million realized loss for three and six months ended June 30, 2023).

As at June 30, 2024, the Company has capital commitments, which is net of advances to suppliers, of $76.3 million through contracts and purchase orders which are expected to be incurred over a six-year period. In the normal course of operations, the Company may also enter into long-term contracts which can be cancelled with certain agreed customary notice periods without material penalties.


22.     Subsequent Events

In July 2024, the Company signed a definitive earn-in agreement ("Agreement") with Salobo Metais S.A, a subsidiary of Vale Base Metals ("VBM"), for the Furnas copper project ("Furnas" or the "Project") located in the Carajás Mineral Province in Pará State, Brazil. The Agreement contemplates the Company earning a 60% interest in the Project upon completion of several exploration, engineering and development milestones over a period of five years from the execution of a definitive earn-in agreement. In exchange for its 60% interest, the Company will solely fund a phased exploration and engineering work program during the earn-in period and grant VBM up to an 11.0% free carry on future Project construction capital expenditures.

2024 PRODUCTION AND COST GUIDANCE(*)

The Company is reaffirming its consolidated copper production guidance of 59,000 to 72,000 tonnes in concentrate, with production expected to be weighted towards H2 2024 largely due to the projected ramp-up of production at the Tucumã Project. Contributions from the Tucumã Project, combined with significantly lower concentrate treatment and refining charges, as well as a more favorable USD to BRL exchange rate, are expected to result in lower consolidated copper C1 cash costs in H2 2024 compared to H1 2024. As a result, the Company is reaffirming its full-year consolidated copper C1 cash cost guidance range of $1.50 to $1.75 per pound of copper produced.

The Company is reaffirming its increased full-year gold production guidance range of 60,000 to 65,000 ounces. While slightly lower production is projected to result in higher unit costs in H2 2024 compared to H1 2024, the Company is lowering its 2024 gold cost guidance to reflect exceptional year-to-date unit cost performance. Full-year gold C1 cash cost guidance is now $450 to $550 (originally $550 to $650) per ounce of gold produced, and AISC guidance has been reduced to $900 to $1,000 (from $1,050 to $1,150) per ounce of gold produced.

The Company's cost guidance for 2024 assumes a foreign exchange rate of 5.00 BRL per USD, a gold price of $1,900 per ounce and a silver price of $23.00 per ounce.

Reconciliation of Non-IFRS Measures

Financial results of the Company are presented in accordance with IFRS. The Company utilizes certain alternative performance (non-IFRS) measures to monitor its performance, including copper C1 cash cost, copper C1 cash cost including foreign exchange hedges, gold C1 cash cost, gold AISC, EBITDA, adjusted EBITDA, adjusted net income attributable to owners of the Company, adjusted net income per share, net (cash) debt, working capital and available liquidity. These performance measures have no standardized meaning prescribed within generally accepted accounting principles under IFRS and, therefore, amounts presented may not be comparable to similar measures presented by other mining companies. These non-IFRS measures are intended to provide supplemental information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

For additional details please refer to the Company’s discussion of non-IFRS and other performance measures in its Management’s Discussion and Analysis for the three and six months ended June 30, 2024 which is available on SEDAR+ at www.sedarplus.ca, and on EDGAR at www.sec.gov.

This press release contains “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 and “forward-looking information” within the meaning of applicable Canadian securities legislation (collectively, “forward-looking statements”). Forward-looking statements include statements that use forward-looking terminology such as “may”, “could”, “would”, “will”, “should”, “intend”, “target”, “plan”, “expect”, “budget”, “estimate”, “forecast”, “schedule”, “anticipate”, “believe”, “continue”, “potential”, “view” or the negative or grammatical variation thereof or other variations thereof or comparable terminology. Forward-looking statements may include, but are not limited to, statements with respect to the Company's expected production, operating costs and capital expenditures at the Caraíba Operations, the Tucumã Project and the Xavantina Operations; estimated timing for certain milestones, including ramp-up of production levels, at the Tucumã Project; expected progress at the new external shaft at the Caraíba Operations; expectations related to foreign exchange rates as well as copper concentrate treatment and refining charges; and any other statement that may predict, forecast, indicate or imply future plans, intentions, levels of activity, results, performance or achievements.

Forward-looking statements are subject to a variety of known and unknown risks, uncertainties and other factors that could cause actual results, actions, events, conditions, performance or achievements to materially differ from those expressed or implied by the forward-looking statements, including, without limitation, risks discussed in this press release and in the Company’s Annual Information Form for the year ended December 31, 2023 (“AIF”) under the heading “Risk Factors”. The risks discussed in this press release and in the AIF are not exhaustive of the factors that may affect any of the Company’s forward-looking statements. Although the Company has attempted to identify important factors that could cause actual results, actions, events, conditions, performance or achievements to differ materially from those contained in forward-looking statements, there may be other factors that cause results, actions, events, conditions, performance or achievements to differ from those anticipated, estimated or intended.

Forward-looking statements are not a guarantee of future performance. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Forward-looking statements involve statements about the future and are inherently uncertain, and the Company’s actual results, achievements or other future events or conditions may differ materially from those reflected in the forward-looking statements due to a variety of risks, uncertainties and other factors, including, without limitation, those referred to herein and in the AIF under the heading “Risk Factors”.

The Company’s forward-looking statements are based on the assumptions, beliefs, expectations and opinions of management on the date the statements are made, many of which may be difficult to predict and beyond the Company’s control. In connection with the forward-looking statements contained in this press release and in the AIF, the Company has made certain assumptions about, among other things: favourable equity and debt capital markets; the ability to raise any necessary additional capital on reasonable terms to advance the production, development and exploration of the Company’s properties and assets; future prices of copper, gold and other metal prices; the timing and results of exploration and drilling programs; the accuracy of any mineral reserve and mineral resource estimates; the geology of the Caraíba Operations, the Xavantina Operations and the Tucumã Project being as described in the respective technical report for each property; production costs; the accuracy of budgeted exploration, development and construction costs and expenditures; the price of other commodities such as fuel; future currency exchange rates and interest rates; operating conditions being favourable such that the Company is able to operate in a safe, efficient and effective manner; work force continuing to remain healthy in the face of prevailing epidemics, pandemics or other health risks, political and regulatory stability; the receipt of governmental, regulatory and third party approvals, licenses and permits on favourable terms; obtaining required renewals for existing approvals, licenses and permits on favourable terms; requirements under applicable laws; sustained labour stability; stability in financial and capital goods markets; availability of equipment; positive relations with local groups and the Company’s ability to meet its obligations under its agreements with such groups; and satisfying the terms and conditions of the Company’s current loan arrangements. Although the Company believes that the assumptions inherent in forward-looking statements are reasonable as of the date of this press release, these assumptions are subject to significant business, social, economic, political, regulatory, competitive and other risks and uncertainties, contingencies and other factors that could cause actual actions, events, conditions, results, performance or achievements to be materially different from those projected in the forward-looking statements. The Company cautions that the foregoing list of assumptions is not exhaustive. Other events or circumstances could cause actual results to differ materially from those estimated or projected and expressed in, or implied by, the forward-looking statements contained in this press release. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.

Forward-looking statements contained herein are made as of the date of this press release and the Company disclaims any obligation to update or revise any forward-looking statement, whether as a result of new information, future events or results or otherwise, except as and to the extent required by applicable securities laws.

CAUTIONARY NOTES REGARDING MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

Unless otherwise indicated, all reserve and resource estimates included in this press release and the documents incorporated by reference herein have been prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects (“NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission (the “SEC”), and reserve and resource information included herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, this press release and the documents incorporated by reference herein use the terms “measured resources,” “indicated resources” and “inferred resources” as defined in accordance with NI 43-101 and the CIM Standards.

Further to recent amendments, mineral property disclosure requirements in the United States (the “U.S. Rules”) are governed by subpart 1300 of Regulation S-K of the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”) which differ from the CIM Standards. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system (the “MJDS”), Ero is not required to provide disclosure on its mineral properties under the U.S. Rules and will continue to provide disclosure under NI 43-101 and the CIM Standards. If Ero ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the MJDS, then Ero will be subject to the U.S. Rules, which differ from the requirements of NI 43-101 and the CIM Standards.

Pursuant to the new U.S. Rules, the SEC recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”. In addition, the definitions of “proven mineral reserves” and “probable mineral reserves” under the U.S. Rules are now “substantially similar” to the corresponding standards under NI 43-101. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that Ero reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms under the U.S. Rules are “substantially similar” to the standards under NI 43-101 and CIM Standards, there are differences in the definitions under the U.S. Rules and CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that Ero may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had Ero prepared the reserve or resource estimates under the standards adopted under the U.S. Rules.
