POSITIVE RESOURCE DRILLING AT TAVSAN
Ariana Resources plc ("Ariana" or the "Company"), an AIM-listed mineral exploration and development company with gold mining interests in Europe, is pleased to announce recent resource and exploration drilling results obtained from the Tavsan Project. The project is operated by Zenit Madencilik San. ve Tic. A.S. ("Zenit") in partnership with Proccea Construction Co. and Ozaltin Holding A.S. and is 23.5% owned by Ariana.
Highlights:
· Infill resource drilling results from Tavsan include:
o 17.8m @ 2.93g/t Au + 5.1g/t Ag
incl. 3.2m @ 6.84g/t Au + 8.3g/t Ag
o 12.0m @ 1.70g/t Au + 2.9g/t Ag
incl. 5.3m @ 2.0g/t Au + 2.6g/t Ag
o 12.9m @ 1.57g/t Au + 1.9g/t Ag
· 96 new holes drilled within the Mineral Resource area, providing data for a revised Mineral Resource Estimate.
· Work on the Mineral Resource Estimate is well underway, with a Feasibility Study to be updated on completion of the new Resource Estimate.
· 12 geotechnical drill-holes were also completed at the proposed Tavsan processing plant site.
Dr. Kerim Sener, Managing Director, commented:
"These drilling results have continued to reinforce our understanding of the Tavsan gold-silver deposit and have largely extended the footprint of known mineralisation, particularly across the North Zone. In fact, some of the highest grades and widest intercepts of mineralisation in the whole project are now located in this zone. Accordingly, we are expecting a significant improvement in the Mineral Resource Estimate in this area in particular.
"Permitting for Tavsan is now nearing conclusion and the construction stage of the project is due to commence in July, once financing arrangements are completed. We will be revising our Feasibility Study for Tavsan on completion of the new Resource Estimate and once finance terms are agreed. This is an exciting time in the development of our second mine in Turkey and further updates to the market will be provided in due course."
Drilling Programme
Between November 2021 and March 2022, a 4,354.8m geotechnical and resource infill drilling programme was completed at Tavsan. Ninety-six drill holes for a total of 3,871.7 metres of HQ diamond drilling was completed specifically for resource infill, covering all four major mineralised zones at Tavsan. At the peak of the programme, three drill rigs were operating simultaneously. The average depth for all drilling was approximately 39 metres, with a minimum depth of 3.8 meters and a maximum depth of 114.30 metres. All holes, except for one hole angled at 45o, were drilled vertically.
The primary objective of the 2021/2022 drilling programme at Tavsan was to provide infill drilling data between historic drill collars to support a reclassification of the Tavsan resources, primarily into the Measured and Indicated categories. To date, all assay results for gold and silver have returned from both the Zenit and ALS laboratories. The majority of the multi-element AAS results have also been returned, with only a few batches of samples remaining.
The results received include 55 holes which intercepted gold mineralisation exceeding 1g/t Au over a sample length of 1 meter, to a maximum intercept of 17.8 meters, these include:
· TAV-D66-21: 17.8m @ 2.93g/t Au + 5.1g/t Ag,
incl. 3.2m @ 6.84g/t Au + 8.3g/t Ag
· TAV-D69-22: 12.0m @ 1.70g/t Au + 2.9g/t Ag
Incl. 5.3m @ 2.0g/t Au + 2.6g/t Ag
· TAV-D90-22: 12.9m @ 1.57g/t Au + 1.9g/t Ag
North Zone
Thirty-seven new drill holes have been drilled within the Tavsan North Zone. These holes have intercepted some of the widest intervals and highest grades of the 2021/2022 programme including holes TAV-D66-21, TAV-D69-22, TAV-D79-22 and TAV-D90-22. Average drill hole spacing within the North Zones is now approximately 48 metres. Step-out drilling from the existing resource holes has expanded the known mineralisation footprint by up to 120 metres.
Main Zone
The Main Zone contains the bulk of the Tavsan Mineral Resource Estimate. Thirty-eight new drill holes were drilled within the Tavsan Main Zone. This drilling shows that the most consistent grades occur within the 0.3km2 Main Zone resource area, with average intercept values ranging from 1g/t Au to 4g/t Au respectively. The average collar spacing within the Main Zone is now 38 meters. Surface grades defined from the 2019/2020 rock saw channel sampling have identified some of the most significant grades peaking at 18.8g/t Au over a 1.4 metre interval (TAV-CH087-19).
West Zone
Twenty-one new holes were drilled at the Tavsan West Zone. Drilling here has confirmed mineralisation where historic drilling was probably terminated too early. However, overall, the mineralisation at Tavsan West Zone is generally lower grade with average intercept values ranging from 0.5g/t Au to 2g/t Au. Average drill collar spacing at Tavsan West Zone is now 48 metres.
Mineral Resource Estimate
In January 2020, an extensive rock-saw channel sampling programme, sampling over 60 outcrop locations within the immediate Tavsan resource area was completed (see RNS 22 January 2020). This contributed to a revised resource estimate corresponding to a 50% increase in the Tavsan Mineral Resource to 4.49Mt at 1.76g/t Au and 5.0g/t Ag for 253,000 oz Au and 723,000 oz Ag, across all classification categories (see RNS 11 June 2020). The next phase of estimation work will involve the integration of the latest drilling data which is expected to add further confidence to the Mineral Resource Estimate. Updates to the Tavsan Mineral Resource are now well underway, and will be reviewed by both the Ariana and Zenit Mineral Resource Estimation teams in the coming weeks.
In parallel with the new assays, extensive drill core density data has been collected to support the Tavsan development programme and revisions to the Mineral Resource Estimate. During the 2021/2022 programme, a total of 896 density measurements have been acquired. From this data, the Tavsan mineralisation has been determined to range from 2.57g/cm3 to 2.64g/cm3, depending on the intensity of brecciation and/or silicification.
Twelve geotechnical diamond drill-holes totalling 374.6m were completed to the North West of the Tavsan North Zone. These holes were designed to supplement the Tavsan Feasibility Study by providing detailed geotechnical data for the foundations of the proposed Tavsan processing plant.http://www.rns-pdf.londonstockexchange.com/rns/1110P_1-2022-6-16.pdf

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 assessed systematically and are grouped according to individual mineralised zones at the Tavsan Sector.
HQ size drill-core samples from the drilling programme at the Tavsan deposit were cut in half by a diamond saw and sent for analysis in batches in line with the Company's quality control procedures. A total of 3,998 samples (including 632 QA/QC samples) were submitted to the Kiziltepe Mine Laboratory. Core recovery for all drilling conducted at Tavsan during this campaign was 83%, for a total of 2,854 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 required 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.
