DERYA VEIN DRILLING RESULTS

Substantial set of new drilling results from the Kiziltepe Mine programme

Ariana Resources plc ("Ariana" or "the Company"), the AIM-listed exploration and development company operating in Europe, is pleased to announce recent and substantial resource drilling results obtained from the Derya area of the Kiziltepe Mine ("Kiziltepe" or "the Project").  Kiziltepe 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:

· Drilling programme testing the central and south-eastern extents of the Derya vein system over 670m of strike to depths of c. 130m below surface.

· New significant intercepts within the vein system include:

o  4.2m @ 6.07g/t Au + 98.2g/t Ag

o  7.1m @ 2.23g/t Au + 11.3g/t Ag

o  2.5m @ 6.07g/t Au + 71.8g/t Ag

· Confirmation of high-grade continuity to depths exceeding 100m from surface within the central part of the Derya vein.

· High-grade potential at Derya includes the previously reported "Bonanza Zone" intercept of 12.1m @ 13.1g/t Au + 187.6g/t Ag.

· Further pit optimisation will be undertaken in the coming months to determine the next stage of open-pit development in this area. 

Dr. Kerim Sener, Managing Director, commented:

"This is yet another substantial set of new drilling results from the Kiziltepe Mine exploration programme.  Derya is continuing to yield higher gold grades, particularly in the central part of the vein system and in an area within about 50m vertical depth below the current pit bottom. 

"As the Derya pit continues to be developed, specifically towards the northwest, the pit is likely to be deepened to enable access to these higher-grade areas.  Further pit optimisation will be undertaken in the coming months to determine the next stage of open-pit development in this area. 

"It is also apparent that the Derya vein system links up with the Arzu structure, suggesting further potential to extend the limits of known gold and silver mineralisation between the Arzu and Derya open pits, the pit rims of which are only about 300m apart based on the current mine plan.  In addition, it is now apparent that the vein system, like Arzu North, comprises several sub-parallel vein structures and the gold mineralisation is not confined to a single structure."

Drilling Programme

Since late December 2020, the Ariana and Zenit exploration teams have drilled 10,052 metres of diamond drill core for over 70 holes.  The programme is the Company's most significant drilling campaign to date, which aims to expand on the open-pittable and potential underground resources, in addition to systematically testing several significant exploration targets within the Kiziltepe area.  This announcement is the third in a series of updates following the release of further assay results from the Kiziltepe mine laboratory.  Earlier announcements include those encompassing the Arzu North (29 April 2021) and Banu (17 May 2021) areas.  This release focuses on the Derya area of the Kiziltepe Mine. 

Drilling Results

Drilling completed at Derya during the summer of 2019 (as announced 17 October 2019) focused on resource infill drilling of the Derya vein structure to provide further confidence to optimisation studies.  At the time, the overall width of the Derya vein system was not known.  Newly acquired grade control data (as announced 18 February 2021), highlighted two additional parallel structures to the Derya main vein exceeding 1m in true width.  These structures were historically poorly tested and insufficient data existed to create any robust geological models of them.  This latest drilling programme was designed to test a wider section of the Derya vein system, intercepting these parallel structures near surface, as well as targeting the Derya main vein at untested depths, or in areas where the drill spacing could be improved (Table 1).

Significant intercepts from the latest drilling programme include:

· KTP-D02-21 (73.7m to 77.9m) 4.2m @ 6.07g/t Au + 98.2g/t Ag

· KTP-D05-21 (44.7m to 51.8m) 7.1m @ 2.23g/t Au + 11.3g/t Ag

· KTP-D04-21 (68.5m to 71m) 2.5m @ 6.07g/t Au + 71.8g/t Ag.

Drill holes KTP-D02-21, KTP-D03A-21, KTP-D04-21 and KTP-D05-21 represent resource infill along the Derya main vein, and specifically target depths exceeding the current design pit limits (approximately 60-70m).  The results show that there is significant scope for a deeper pit to be developed in the longer term (Figure 1 & 2).

Holes KTP-D51-21, KTP-D53-21, KTP-D56-21 and KTP-D58-21 all target the Derya main vein at a vertical depth exceeding 100m.  The area targeted is specifically testing approximately 50m below the KTP-D18-11 "Bonanza" zone - 12.1m @ 13.1g/t Au + 187.6g/t Ag (as announced on 21 May 2012), and will add significant information to the next iteration of the resource estimation and pit optimisation at Derya.  The results of KTP-D53-21 (1.1m @ 4.27g/t Au + 3g/t Ag) from a downhole depth of about 160m, demonstrate higher grades in the central and deeper parts (130 vertical metres) of the Derya vein, with the mineralisation remaining open at depth (Figure 2).  Other holes, drilled during previous campaigns in the vicinity (17 to 39m away from) the "Bonanza" zone, notably KTP-RC14-10: 11m @ 2.46g/t Au + 47.1g/t Ag; KTP-RC12-10: 2m @ 8.23g/t Au + 223.2g/t Ag; KTP-RC11-19: 14m @ 2.22 g/t Au + 15.1g/t Ag, confirm the presence of a significant zone of mineralisation in this area.

Finally, drill holes KTP-D08-21, KTP-D14-21, KTP-D17-21 and KTP-D20-21 were designed to provide additional confidence to existing drilling, testing the zone linking the Derya, Arzu Central and Arzu South structures.  Here, several structures have been intercepted at various depths.  Most significantly, several new intercepts of the Arzu South Parallel structure (as announced on 19 October 2016) show the structure continuing a further 170m northwest towards Derya.  The additional drilling in this area has further highlighted the potential for an extension of the Arzu South pit towards Derya, and perhaps the future merging of the Derya, Arzu South and Arzu North pits, which remains a significant focus for future drilling in the immediate area (Figure 1 & 2).

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 Kiziltepe 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 Derya drilling, a total of 1,818 samples (including 287 QA/QC samples) were submitted to the Kiziltepe Mine Laboratory.  Core recovery for all drilling conducted at Derya during this campaign was 87%, for a total of 942 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.
