DOKWE GOLD PROJECT

REVISED PRE-FEASIBILITY STUDY

Ariana Resources plc ("Ariana" or "the Company"), the AIM-listed mineral exploration and development company with gold project interests in Africa and Europe, is pleased to announce an interim revision to the Dokwe Pre-Feasibility Study ("Dokwe" or "the Project") in Zimbabwe. Dokwe is 100% owned by Rockover Holdings Limited ("Rockover") and is subject to outright acquisition by Ariana through the merger announced on AIM: 25 April 2024.

Highlights:

·    Pre-Feasibility Study ("PFS") financial model update on the Reserves at Dokwe North provide a post-tax NPV₁₀ of US$160 million and an IRR of 41% at a gold price of US$2,000/oz.*

·    PFS outlines a mine life of c.13 years producing at a rate of c.60,000 ounces of gold per annum (up to 76,000 ounces p.a.) from a single, staged, open-pit with processing primarily via CIL, at an all-in sustaining cost ("AISC") of US$1,144 per ounce.

·    Peak capital funding requirement is estimated at US$82 million, assuming implementation of the full mining and processing plan from mine start-up, rather than a staged approach to capital investment; the expected payback period for the Project is 2.7 years from the start of production.

·    Further revisions to the PFS will commence following the completion of a revised Mineral Resource Estimate for Dokwe North and Central

·    Several potential exploration opportunities to increase the Resource have been identified at Dokwe North and Dokwe Central, and across the wider area.

* For the purposes of this update, the pits were not re-optimised and quotes for individual CAPEX and OPEX components were not revised, with CPI and exchange rate changes considered.

Dr. Kerim Sener, Managing Director, commented:

"This substantial update to the Dokwe Project PFS further underscores our assessment that the Project represents a major value-accretive opportunity for the proposed enlarged Company once we complete our merger with Rockover. Notably, the revised PFS only includes the Dokwe North area and there is significant scope to enhance the economics further if Dokwe Central is included.

"As it stands, Dokwe represents a significantly de-risked, advanced project development opportunity containing established Reserves, which has been sufficiently well drill-tested to enable its immediate advance to the Feasibility stage. On completion of the merger with Rockover, the project will propel Ariana towards mid-tier company status, as we continue to build on our mine development strategy and gain enhanced market recognition.

"Finally, we anticipate positive developments through further project optimisation studies of the Dokwe Project, which require ongoing assessment, along with similar studies being undertaken across the rest of our project portfolio. Such project developments are communicated to the market via our regulatory announcements at the earliest feasible time. We continue to work hard to expand the opportunity at Dokwe and we will keep the market informed of our progress."

About the Dokwe Project

The Dokwe North and Dokwe Central gold deposits are located 2km apart ("Dokwe" or "Dokwe Project") and are situated in the Tsholotsho Communal Land 110km WNW of Bulawayo, Zimbabwe (Figure 1). Bulawayo is the second largest city in Zimbabwe (population 660,000) with excellent road, rail and air links to the rest of the country and internationally, and represents a significant mining services and educational centre, hosting both the Zimbabwe School of Mines and the National University of Science and Technology.

The Dokwe Project was discovered by Rockover in 2002, utilising innovative soil geochemical exploration methods capable of detecting mineralisation beneath cover, subsequently drill-tested for the first time in 2004. It represents the largest undeveloped gold project in Zimbabwe and is currently 100% owned by Rockover Holdings Limited.

Certain previous drill intercepts are also identified, with details provided in Table 1 below. The 2023-2024 due diligence drilling collars are also shown in magenta.

Tenure

Dokwe is held by Rockover through 81 blocks of gold claims and a further 22 copper base metal claims totalling 4,040 hectares ("Mining Claims", Figure 2). A private Net Smelter Return ("NSR") royalty of 0.5% applies to the aforementioned claims. An application has been made to convert the claims into a single Mining Lease for gold and base metals covering 6,622 hectares (Figure 2). In addition, seven Exclusive Prospecting Orders ("EPOs") have been applied for in the vicinity of the Dokwe Project extending towards Bulawayo.

Summary of Geology

Dokwe is located within a covered Archaean Greenstone Belt, extending from the border with Botswana (Maitengwe greenstone belt) and linking up with the Bulawayo-Bubi Greenstone Belt to the east. The Archaean greenstone units are overlain by Karoo and Kalahari sedimentary units of up to 25-40m in thickness. The east-northeast striking greenstone belt has been complexly folded and thrust-faulted and is dissected by a series of major sub-parallel sinistral shear zones.

At the Dokwe Gold Project area, the barren sedimentary cover is dominated by calcrete, with a few metres of sand at the surface, and mudstone and sandstone located towards the base. The basement Archaean volcanic sequence comprises a series of quartz-rich volcaniclastic units, tuffs, and agglomerates, that grade into felsic irregular rhyolitic flows; intermediate vesicular dacite; agglomerates and andesites. The volcanic sequence has undergone greenschist facies metamorphism and deformation. The sequence appears intruded by near syn-depositional quartz porphyries and later by dolerite. While brittle-ductile deformation occurs throughout the deposit, somewhat more brittle deformation, characterised by fracturing, is common in felsic tuff and porphyry units whilst rather more ductile deformation characterises the dacitic and andesitic units.

Dokwe North is characterised as a large low-grade deposit containing relatively few quartz veins, with several very high-grade zones including visible gold (Table 1). Due diligence drilling is confirming this understanding of the grade distribution within the deposit (Table 2). Dokwe Central is a smaller higher-grade pipe-like deposit containing abundant quartz veins and several steeply plunging high-grade zones. The two deposits appear to be strongly structurally controlled, occupying two distinct structural domains within a broad ENE trending shear zone. Gold mineralisation at Dokwe North is associated with silicified zones containing thin quartz-carbonate pyrite veins and narrow shears. There is also an association with strongly disseminated, fine-grained pyrite in the host rocks. Much of the economic gold mineralisation occurs in the dacitic unit and in the overlying felsic tuff, with lesser mineralisation in the quartz porphyry and andesitic units.

Table 2: Intercepts from 2023-2024 due-diligence drilling, from DPD129, calculated using a 0.2 g/t Au cut-off (representing down-hole widths). Allowing up to 6m of internal dilution provides for a total mineralised intercept of 93.2m @ 1.80 g/t Au (from 86.0m to 179.2m).

Mineral Resources and Reserves

Dokwe North has a JORC (2012) Compliant Measured, Indicated and Inferred Resource of 35.7Mt @ 1.05g/t Au for 1,210,000 oz gold (Table 3). Dokwe Central, which is located approximately 2km to the SSE of Dokwe North, has a JORC (2004) non-AIM compliant Indicated and Inferred Resource of 1.14Mt @ 2.17g/t Au for 80,000 oz gold (Figure 4). The Dokwe Central resource is treated here as a historical estimate as it is not in accordance with an AIM reporting standard and should be treated with caution. From the initial reviews, both project areas have significant scope for further exploration upside. Ore Reserves have only been estimated for Dokwe North as part of the PFS (dated 1 September 2022), with a total of 18.25Mt at 1.36g/t Au for 795,800oz gold (Table 4).

Pre-Feasibility Study

An independent Pre-Feasibility Study was commissioned by Rockover and was completed in 2022 by Minxcon (Pty) Ltd in South Africa ("Minxcon") and then revised as a financial model update in May 2024 to account for a higher gold price forecast (US$1,650/oz to US$2,000/oz), CPI and associated exchange rate (South African Rand to US Dollars) adjustments for CAPEX and OPEX calculated at NPV₁₀ rather than NPV₈. Further revisions to the PFS will be undertaken in due course to accommodate a revised Mineral Resource Estimate, pit optimisations and re-quotes on CAPEX and OPEX, among other refinements.

For the purposes of the May 2024 update, the pits have not been re-optimised and quotes for individual CAPEX and OPEX components were not updated. A cost escalation based on South African CPI was adjusted for US exchange rate, resulting in a slight decrease in CAPEX and OPEX. As a result, the original PFS numbers were used for this update. CAPEX and OPEX will be updated with re-quotes as part of a more detailed revision of the PFS that is in the process of being commissioned. The next PFS revision will also include revised geological models and the expected inclusion of Dokwe Central into the mining plan.

A combined Proven and Probable Ore Reserve Estimate comprising 18.25Mt grading 1.36g/t Au for 795,800 ounces of gold was declared (Table 5) for Dokwe North as part of the 2022 PFS. Both the Mineral Resource Estimate and Ore Reserve calculation have been prepared in compliance with JORC 2012.

The PFS outlined a plan to develop the project as an open pit mining operation producing 1.5Mt of ore per annum from a single pit, at a stripping ratio of 5:1. The mine is envisaged to be contractor operated with an owner's management team. The pit development is staged, prioritising high-grade ore. Ore will be processed at a treatment plant to be constructed on-site with a treatment capacity of 125,000tpm, allowing for production of c.60,000 ounces per annum (up to 76,000 ounces p.a.). Both Carbon in Leach ("CIL") and Heap Leach ("HL") treatment methods were considered viable for the purposes of the PFS, demonstrating similar economics, and both methods will be considered further in a future Feasibility Study.

The revised PFS economic results provide for a mine life of 13 years at a post-tax NPV₁₀ of US$160 million and an IRR of 41% at a gold price of US$2,000/oz. This is based on a CIL processing route. The Project's all-in sustaining cost (AISC) is US$1,144 per ounce with an AISC margin of 42%.

To fund the Project, a capital investment of US$82 million (peak funding requirement) is required, assuming implementation of the full mining and processing plan from mine start up, rather than a potential scaled and staged approach to capital investment. The expected payback period for the Project is 2.7 years from the start of production.

Sensitivity analyses indicate that the Project is most affected by changes in grade and gold price, while it is least sensitive to capital requirements.
