Solaris Provides Warintza Operations Update, 2024 Drilling to Exceed 75,000m and Early Works Infrastructure Development Underway

QUITO, Ecuador, Nov. 12, 2024 (GLOBE NEWSWIRE) -- Solaris Resources Inc. (TSX: SLS; NYSE: SLSR) (“Solaris” or the “Company”) is pleased to provide a Warintza Project (“Warintza” or “the Project”) update, including the latest assay results from its ongoing 2024 drilling program, now set to exceed 75,000m, and report on technical programs and early works infrastructure development.

Project Update

Drilling

• Solaris achieved the 60,000m of planned meterage for its 2024 drilling program by the end of October, and is now set to exceed 75,000m by the end of the year
• Drilling continues with nine rigs primarily focused on extension and infill of the 2024 Mineral Resource Estimateˆ (“MRE”), while also testing its connection to the Warintza West deposit, which lies outside the MRE and could deliver significant growth in an expanded pit shell

Infrastructure Development

• The Company has advanced early works infrastructure development, including the improvement of 25km of road access connecting the Project to the highway grid and recent construction of 8km of new roads to support drilling activities, logistics, and mobilization (refer to Figure 1)
• Construction continues on a further 7km of roads strategically located to support future mining operations and access to the anticipated pre-stripping and drilling areas, process plant, Waste Rock Facility (“WRF”) and Tailings Management Facility (“TMF”)

Technical Programs

• Geotechnical and hydrogeological drilling, field testing, sampling and instrumentation programs have been completed for the anticipated TMF, and are underway for the anticipated open pit, WRF, process plant and internal infrastructure and expected to be completed by year-end
• Knight Piésold Consulting is in the process of completing engineering studies for the anticipated TMF and Water Permit, with the final reports expected to be completed in the coming weeks to support the Environmental Impact Assessment review period

Metallurgical and Processing Studies

• The metallurgical drilling program to supplement prior test work (refer to press release dated January 23, 2023) has been completed
• Comminution testing has been completed and has returned a more detailed profile with reduced hardness in the upper part of the deposit than prior test work had suggested
• Next steps are additional flotation tests with a focus on reagent optimization for recovery improvement which is expected to be completed by year-end
• Ausenco Engineering is working on the process plant design and a preliminary flowsheet has been established, with prior test work returning high quality concentrates for copper (gold) and molybdenum

Assay Results

Drill results continue to build on the MRE, with holes SLS-111 and SLS-107 improving upon the modelled grade in its vicinity, while holes SLS 110, SLS 113-116 and SLSE-64 encountered mineralization partially outside of the MRE in the southern and northeastern sectors.

• SLS-111 (drilled southeast): 90m of 1.12% CuEq² within 475m of 0.46% CuEq² from surface
• SLS-107 (drilled northeast): 96m of 0.82% CuEq² within 543m of 0.51% CuEq² from surface

Step-out exploration drilling to the northwest of the MRE testing its connection to the Warintza West deposit has been completed with assays expected in the coming weeks, representing an opportunity for expansion of the MRE in an enlarged pit.

Notes to Table 1: True widths are interpreted to be very close to drilled widths due to the bulk-porphyry style mineralized zones at Warintza.

Endnotes

1. Refer to the technical report entitled “Mineral Resource Estimate Update - NI 43-101 Technical Report, Warintza Project, Ecuador” with an effective date of July 1, 2024 and available on SEDAR+ under the Company’s profile at www.sedarplus.ca and on the Company’s website.
2. Copper-equivalence grade calculation for reporting assumes metal prices of US$4.00/lb Cu, US$20.00/lb Mo, and US$1,850/oz Au, and recoveries of 90% Cu, 85% Mo, and 70% Au based on preliminary metallurgical testwork. CuEq formula: CuEq (%) = Cu (%) + 5.604 × Mo (%) + 0.623 × Au (g/t).

Technical Information and Quality Control & Quality Assurance
Sample assay results have been independently monitored through a quality control/quality assurance (“QA/QC”) program that includes the insertion of blind certified reference materials (standards), blanks and field duplicate samples. Logging and sampling are completed at a secure Company facility located on site. Drill core is cut in half on site and samples are securely transported to ALS Labs in Quito. Sample pulps are sent to ALS Labs in Lima, Peru and Vancouver, Canada for analysis. Total copper and molybdenum contents are determined by four-acid digestion with AAS finish. Gold is determined by fire assay of a 30-gram charge. In addition, selected pulp check samples are sent to Bureau Veritas lab in Lima, Peru. Both ALS Labs and Bureau Veritas lab are independent of Solaris. Solaris is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein. Heliborne magnetic, LIDAR and other layers of data quality for Warintza district exploration were validated by a qualified external professional using data validation procedures under high industry standards and the Company therefore did not require such data to be further verified by a “Qualified Person” as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects. The remaining scientific and technical information, including the drillhole data, has been verified by Jorge Fierro, M.Sc., DIC, PG, using data validation and quality assurance procedures under high industry standards. The verification activities included a search for factual errors, completeness of the lithological and assay data, and suitability of the primary data. As part of the database verification activities, the assay information and certificates obtained directly from the analytical laboratory have been examined as well.

Qualified Person

The scientific and technical content of this press release has been reviewed and approved by Jorge Fierro, M.Sc., DIC, PG, Vice President Exploration of Solaris who is a “Qualified Person” as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects. Jorge Fierro is a Registered Professional Geologist through the SME (registered member #4279075).
