Dokwe Project Exploration Upside

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 provide an update on its internal exploration data review for the 100% held 1.8Moz Dokwe Gold Project in Zimbabwe, focusing on the near-term potential exploration upside at Dokwe North and Dokwe Central.

Highlights:

• The resources at both Dokwe North and Central remain open along strike and at depth, and there are excellent prospects of increasing the resource with further drilling in the following areas, specifically:

o Several moderately angled southwest plunging higher-grade shoots at the Dokwe North deposit remain untested at depth and demonstrate that the deposit remains open to the south.

o Northwest flank of the Dokwe North deposit shows potential for further mineralisation to be identified at depth within an area of repeated prospective stratigraphy.

o The Dokwe Central deposit remains open to the west and historical intercepts (notably 7.3m @ 6.63g/t gold intercept from 32.2m) to the east indicate that the prospectivity of the Dokwe Central fault zone extends for at least 1km.

• Step-out and infill drilling are being planned to enable appropriate testing of the exploration potential defined to date, with a view to increasing the resource to 2Moz of gold.
• Kerim Sener, Managing Director, commented:

"Our review of the exploration data and geology of the Dokwe North and Central areas has led to the identification of several zones showing potential for significant resource upside. Based on our current assessments, we are targeting potential enhancement of the resource to at least 2Moz of gold.

"At Dokwe North, a detailed reassessment of the geology and the structural controls on mineralisation is yielding a refined understanding of the upside opportunities. In particular, several high-grade zones are noted which display good strike continuity through the deposit, trending northeast-southwest and plunging at a moderate angle to the southwest. This opens up the southern end of the deposit for further exploration. In addition, deeper holes on the deposit in the northwest, suggest the potential for repeated prospective stratigraphy, notably dacite and tuff, indicating that there is an opportunity to encounter good mineralisation on the northern flanks of the deposit.

"At Dokwe Central, we have now demonstrated an opportunity to define further mineralisation along strike over a distance of approximately 1km along a faulted contact between volcanic and sedimentary units. Several historic drill hole intercepts along this structure suggest that a well-defined mineralised zone developed in the immediate vicinity of the fault zone and trends broadly east-west. Notably, a historic 7.3m @ 6.63g/t gold intercept from 32.2m identified gold mineralisation within the Archaean units just beneath the cover sequence and has not yet been followed up with further drilling.

"In summary, there is excellent potential at Dokwe North and Central to continue growing the resource base in a material way and we are designing new drilling programmes accordingly. We look forward to updating the market on this work in due course."

Background

The prospective Archaean rocks at the Dokwe Project were buried, deformed, metamorphosed, and mineralised, before being uplifted and partially eroded to form a basin into which the post-Permian Karoo sedimentary and volcanic rocks were deposited. The Karoo-aged rocks and the later Kalahari sediments form a cover layer over the Archaean rocks, ranging in thickness from a few metres at Dokwe South, gradually thickening northwards to approximately 40 metres at Dokwe North (Figure 1).

In 2001, a regional soil sampling programme commenced, and over the following few years, several areas of gold anomalism were highlighted as targets for drilling. In 2004, Dokwe North and Dokwe Central were discovered by drilling beneath two of these targets (Figure 2). An intriguing aspect of the geochemical targets is the apparent regular spacing of approximately 2.5km between each anomaly area (Figure 2).

Ariana is currently undertaking a review of historical exploration data across the Dokwe Project and a range of opportunities are identified. These include potential expansions to the Dokwe North Deposit; strike and depth continuations to the Dokwe Central deposit, with exploration potential over a strike length of at least 1km.

Future Exploration Methodology

The deepening cover northwards across the project area means that different exploration methods will need to be applied to different sub-areas. In the south, where the cover is relatively shallow, mapping, testing of sub-crop and portable XRF soil sampling are likely to produce results, whereas further north, testing the greenstones will require techniques capable of testing greater depths, such as drilling and geophysics.

Following an assessment of the cover rocks and uppermost greenstones, it is apparent that the area is ideal for Rotary Air Blast drilling ("RAB"), a rapid, relatively inexpensive and widely employed drilling technique that has been successful in discovering numerous gold deposits in similar terranes across Western Australia, which has not been used at Dokwe previously. It is expected that the degree of weathering of the greenstones beneath the cover will enable at least 20m of greenstones to be tested in each hole before blade refusal. As part of a comprehensive new exploration programme, the Company is designing an RAB drilling grid to test the project area in more detail, intending to penetrate the underlying Archaean units throughout a large part of the project.

Dokwe North Extensions

The collection and interrogation of new geological information acquired by the Ariana team over the past year has improved the understanding of the geology, geometry, and exploration upside of Dokwe North. The current interpretation is that gold mineralisation is primarily hosted within a folded sequence of felsic-to-intermediate volcaniclastic rocks. Almost all mineralisation discovered at Dokwe North occurs within the eastern limb of this fold, which is partly intruded by a quartz-feldspar porphyry and later dolerite sills (potentially masking any geochemical response at surface). The primary host rocks are a felsic tuff and dacite, with some peripheral mineralisation within the overlying quartz-feldspar porphyry, and underlying agglomerate and andesitic rocks. The geometry of all these units, based on litho-geochemical modelling of over 28,000 pXRF samples, is now well understood and provides excellent insight for down dip and plunge exploration.

Almost all drilling within Dokwe North is constrained to the eastern limb of the Dokwe North fold structure, with only two holes drilled into the western limb. One of these, DPD7, ended in a moderately mineralised western tuff unit (26m @ 0.73g/t Au, including 2m @ 4.62g/t Au), which has not been followed up.

The apex of the Dokwe North fold was exposed and eroded from at least the Permian Period, before the deposition of the Karoo-aged rocks. Furthermore, the eastern and western limbs are separated by a major NE-SW fault intruded by later dolerite dykes. The mineralisation in the western limb is interpreted to have been down-faulted, making it a significant exploration target for the next phase of work (Figure 3).

In addition, Dokwe North has at least three south plunging higher-grade zones, which form part of the Indicated and Inferred components of the Resource (Figure 3) and remain open down plunge. A better understanding of the geology has provided significant confidence to the understanding of the distribution of higher-grade mineralisation and how it should be extrapolated within the model. To date and based on the June 2024 Mineral Resource Estimate (AIM: 13 June 2024), there is potential for 390,000 ounces of gold, currently classified as Inferred, to be reclassified following further drilling. This will be a primary target for future resource development, and eventual addition to future Reserves, subject to the appropriate studies and modifying factors.

Dokwe Central Extensions

Gold mineralisation along the Dokwe Central fault zone has already been demonstrated with the definition of the 165,000oz Au Dokwe Central deposit. The deepest intercept to date is in DPD73 with 17m @ 5.91g/t Au from 411.7m, such that the mineralisation remains open at depth.

Western Extension:

After reviewing the historical drilling data at Dokwe Central, the Company understands that the deposit is not adequately tested to close off mineralisation to the west (Figure 4). The two most westerly mineralised drill holes define a broad mineralised envelope containing two high-grade mineralised zones. DPD67 intercepted 8m @ 18.34g/t Au from 83.3m and 17m @ 3.21g/t Au from 106.4m, whilst DPD72 intercepted 2m @ 16.01g/t Au from 141.1m and 6m @ 9.74 g/t Au from 153.1m. Only two holes, DPD65 and DPD66 have been drilled further west to close off this broad zone of mineralisation.

Both holes, DPD65 and DPD66, intercepted the footwall sedimentary rocks approximately 90m south of where they would be predicted to be, implying a faulted displacement. If that is the correct interpretation, then the mineralisation is likely to have been faulted southwards too, and remains untested, presenting a highly significant exploration target adjacent to the Dokwe Central resource.

Eastern Extension:

In 2003, two 'scissor' holes were drilled approximately 750m west of the Dokwe Central deposit. One, DPD4, was drilled from south to north, intercepting 7.3m @ 6.63g/t gold from 32.2m, just beneath the cover sequence. Ariana has confirmed that the rock type hosting the mineralisation is similar to the veined felsic schist hosting the main zone of mineralisation at Dokwe Central. The second hole, DPD5, was drilled from north to south but did not go far enough south to intercept the depth projection of the intercept in DPD4.

These holes were two of the earliest drilled at the Dokwe Project, and at about the same time they were drilled, Dokwe North was discovered (DPD7). Soon after, Dokwe Central and the intercept in DPD4 became a lesser exploration priority. Many years later a hole was drilled northwards stepping back from the intercept in DPD4 (DPD106), although the northwest orientation of the hole indicates it was not an adequate test of the DPD4 mineralisation. Ariana is of the view that the target remains open and follow-up drilling is required.

Furthermore, DPD102 intercepted a metre at 13.65g/t Au from 189.61m, approximately 80m east of the mineralisation at Dokwe Central, along with two further metre-wide intercepts greater than 2.0g/t Au, further confirming the significance and potential of this fault zone. Confirmation that the Dokwe Central deposit remains open to the west, in conjunction with intercepts 80m and 750m to the east of the deposit, highlights a highly significant exploration target along the Dokwe fault zone, which extends more than 1km in strike and has seen only very sparse drill testing.
