AIM: AAU
ADDITIONAL KEPEZ NORTH DRILLING RESULTS
Ariana Resources plc ("Ariana" or "the Company"), the AIM-listed mineral exploration and development company with joint-venture gold mining operations in Europe, is pleased to announce recent resource drilling results obtained from the Kepez North ("Kepez" or "the Project") area of the Kiziltepe Sector. Kepez North is part of the Zenit Madencilik San. ve Tic. A.S. ("Zenit") Joint Venture ("JV") with Proccea Construction Co. and Ozaltin Holding A.S. and is 23.5% owned by Ariana.
Highlights:
· New intercepts from surface for the Kepez North scree returned:
o 3.2m @ 11.53g/t Au + 168.7g/t Ag
o 5.3m @ 3.06g/t Au + 62.0g/t Ag
· Infill resource drilling results from the Kepez North vein include:
o 8.8m @ 6.23g/t Au + 26.0g/t Ag
o 6.4m @ 6.23g/t Au + 57.8g/t Ag
Dr. Kerim Sener, Managing Director, commented:
"These additional drilling results from the Kepez North area have further reinforced our understanding of this unusually high-grade zone of gold and silver mineralisation. Following the results of the drilling announced in late June, the joint venture returned the drilling rig to Kepez to complete a drill-out to enable total conversion of the resource to a JORC Measured classification and hence enable the mining team to complete the required work to translate this area to a JORC Proven Reserve status ready for mining to commence. The mining team has been progressing the required planning to allow for the establishment of a small waste-rock dump to the west of Kepez and the associated permitting requirements. The joint venture is looking to expedite the addition of this mining area into the production schedule.
"With a current total JORC Measured and Indicated Resource of 36,400 ounces of gold at a grade of 7.15 g/t Au, Kepez North will provide Kiziltepe with a source of high-grade ore for blending with our current processing plant feedstock. Further exploration will continue in the vicinity, to determine the potential for this vein system to host other spatially restricted but high-grade zones of mineralisation which could add to the mine production schedule in the future."
Drilling Programme
Infill resource drilling was completed on a 25m x 25m grid, down to 10m spacing in the area currently defined as the initial pit to provide confirmation to the final mine design. A total of 18 holes were drilled at Kepez North following the announcement of 30 June 2021, for which results of 5 drill holes were reported. The Kepez North prospect is situated 14km haulage distance from the Kiziltepe processing plant and the area is being advanced through further permitting, with the optimisation study completed as announced on 21 July 2021.
Kepez North
This phase of drilling at Kepez North consisted of 18 inclined diamond drill holes (60 degree dip, 45 degree azimuth) totalling 872.3m (min. depth 34.1m, max. depth 79.7m). Unlike prior drilling programmes which utilised vertical or due east inclined holes, this programme was designed to better test the potential for the high-grade mineralisation along steeply dipping northwest oriented structures which appear to cut the main vein trend (Figure 1).
The Kepez North drilling programme is summarised in Table 1, returning the following results:
· KPZ-D17-21 (19.2m-28.0m) 8.8m @ 6.23g/t Au + 26.0g/t Ag
· KPZ-D18-21 (22.8m-29.2m) 6.4m @ 6.23g/t Au + 57.8g/t Ag
· KPZ-D11-21 (0.0m-8.0m) 8.0m @ 4.62g/t Au + 96.8g/t Ag
· KPZ-D17-21 (0.0m-3.2m) 3.2m @ 11.53g/t Au + 168.7g/t Ag
These additional holes have confirmed and further de-risked the mineral resource estimate announced on 21 July 2021. As before, the results highlight and confirm the significant grade demonstrated near surface within the Kepez North vein and its suitability for near complete extraction via open-pit mining. The currently designed pit captures 81% of the total resource by volume and over 87% of the resource by gold ounces. The joint venture mining team are in the process of expediting mining activities at Kepez North. This phase of drilling also added confidence to the parameters of the highly mineralised scree located above the western flank (hanging-wall) of the main vein.
Optimisation Study
As announced on 21 July 2021, the optimisation found that the resource is not sensitive to changes to the overall pit wall angle between 40-45o. At a pit wall angle of 40o, the pit encompasses 128,300t @ 7.69g/t Au + 69.98g/t Ag, totalling 31,700 oz Au, with a strip-ratio of 2.7. The next stage of development will involve the establishment of a trial pit to confirm the choice of pit wall angles and determine the best method of grade control sampling to be used when mining begins.

Sampling and Assaying Procedures
All diamond drill core is currently being processed at the Kiziltepe mine site and analysed at the Kiziltepe Mine Laboratory. Results are being assessed systematically and are being grouped according to individual vein systems at the Kiziltepe Sector.
HQ size drill-core samples from the drilling programme at the Kepez deposit were cut in half by a diamond saw and sent for analysis in batches in line with the Company's quality control procedures. For all the Kepez North drilling, a total of 908 samples (including 186 QA/QC samples) were submitted to the Kiziltepe Mine Laboratory. Core recovery for all drilling conducted at Kepez North during this phase of the campaign was 82%, for a total of 503 measurements.
All samples were assayed for gold using a 30g fire assay. Reviews of the assay results have determined that all Quality Control and Quality Assurance samples (blanks, standards and duplicates) passed the quality control checks established by the company, with duplicate samples showing excellent correlation. Laboratory sample preparation, assaying procedures and chain of custody are appropriately controlled. The Company maintains an archive of half core samples and a photographic record of all cores for future reference.
