BANU VEIN DRILLING RESULTS

 

Ariana Resources plc ("Ariana" or "the Company"), the AIM-listed exploration and development company operating in Europe, is pleased to announce recent resource drilling results obtained from the Banu 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 south-eastern half of the Banu vein system over 200m of strike to depths of c. 100m below surface.

 

·    New significant intercepts within the vein system include:

 

o  4.1m @ 3.58g/t Au + 78.9g/t Ag

o  7.0m @ 2.01g/t Au + 70.6g/t Ag

o  2.6m @ 5.08g/t Au + 102.5g/t Ag

 

·    Zone of higher-grade mineralisation confirmed at the south-eastern end of the vein system.

 

·    Potential remains to expand the open-pittable strike continuity of the vein system from 300m to c. 700m, and in drilling certain other vein systems in the vicinity.

 

Dr. Kerim Sener, Managing Director, commented:

 

"These results confirm the presence of higher-grade mineralisation towards the south-eastern end of the Banu vein and improve confidence in the mineral resource and reserve estimation.  The results also demonstrate the continuity of the vein system to at least 100m below surface over more than 200m of strike.  The higher-grade zone at Banu, like those on Arzu South, appears to plunge moderately towards the south-east.  This finding, in particular, highlights the opportunity to identify other plunging shoots containing high-grade mineralisation elsewhere along strike.  As with other vein systems at Kiziltepe, additional drilling has proven the potential to add to the resource base, which could lead to further increases to the life of mine."

Drilling Programme

 

Since late December 2020, the Ariana and Zenit exploration teams have been working continuously on the most significant drilling programme to date at Kiziltepe.  The programme aims to significantly expand on the open-pittable and potential underground resources, in addition to systematically testing several significant exploration targets within the Kiziltepe area.  To date, over 8,600 meters of diamond drilling has successfully been completed for 63 holes.  This announcement is the second in a series of updates following the release of further assay results from the Kiziltepe mine laboratory.  On the 29 April 2021, Ariana released the first update of this programme, which focused on results from the Arzu North area.  This release focuses on the Banu area of the Kiziltepe Mine. 

 

In January 2017 (see announcement dated 30 January 2017), a 125m strike extension to Banu was announced based on drilling results completed during late 2016.  These results highlighted the significance of the Banu area, which to date remains one of the least explored vein systems at Kiziltepe.  The current 2021 drilling at Banu focuses on increasing the confidence of the resource within the 125m strike extension, in addition to providing infill between historic surface rock-saw channel samples, to further increase data density in the main resource area and to enable an update of the resources to higher confidence JORC categories. 

 

Drilling Results

 

The latest drilling completed at Banu comprises eleven diamond drill holes for a total of 790.6m.  Assays returned several robust results which provide significant additional data for a further resource update, which will be completed when all results have returned for the wider Kiziltepe area.  Banu remains one of the most consistently mineralised veins at Kiziltepe both along strike and at depth, with new results including:

 

·    KTP-D38-21 (98.9m-103m) 4.1m @ 3.58g/t Au + 78.9g/t Ag

·    KTP-D26-21 (42.9-49.9m) 7m @ 2.01g/t Au + 70.6g/t Ag

·    KTP-D28-21 (20.5-23.1m) 2.6m @ 5.08g/t Au + 102.5g/t Ag

 

Hole KTP-D38-21 represents the second deepest hole drilled into the Banu structure to date, testing a vertical depth of 90m.  The deepest hole at Banu (KTP-RC32-07, 7m @ 1.4 g/t Au + 57.7g/t Ag), intercepts the Banu vein at a vertical depth of 105m.  These holes are separated by approximately 200m and both holes demonstrate that the mineralisation remains well developed to these depths and maintains the potential for high grades.

Pit Optimisation

 

To date, the Banu vein has been tested by drilling to a strike length of 540m and to a vertical depth of 105m.  The mineralisation remains open at depth and along strike to the northwest.  Drilling completed in 2016 defined the south-eastern limit of the Banu vein system, where the host structure eventually narrows (0.2 - 0.5 metres) and shows lower grades (<1g/t Au).  The average thickness of the Banu vein throughout is c. 2 metres with localised blows of up to 5 metres in thickness.

 

Optimisation work completed between 2017 and 2020 identifies the potential for a c. 300m long x 60m wide and 40m deep open-pit at Banu.  The latest drilling provides sufficient additional data to: 1) add confidence to allow a deeper open-pit to be considered, capturing a larger proportion of the current resource, 2) reduces the reliance of historic surface rock-saw channel sampling on the resource estimation, allowing a more robust optimisation study to be completed, and 3) potentially increase the overall resource by expanding the data into more sparsely explored areas of the vein.

 

Future Exploration

 

The Banu and surrounding area will continue to remain a focus for future exploration at Kiziltepe.  To date, only 25% (840 meters) of known veins in the Banu area have been sufficiently tested for resource definition.  The remaining 75% (2,500m) of less tested veins (primarily the Fidan-Gamze and Vein 7 structures), will remain the subject to future drilling plans, subject to approval and expansion of new exploration permits.

Sampling and Assaying Procedures

 

All diamond drill core is currently being processed at the Kiziltepe mine site and analysed at the Zenit 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 Banu drilling, a total of 625 samples (including 98 QA/QC samples) were submitted to the Kiziltepe Mine Laboratory.  Core recovery for all drilling conducted at Banu during this campaign was 94%, for a total of 292 measurements.

 

All samples were assayed for gold using a 30g fire assay. Quality control checks have determined that all blanks and all standards passed and duplicate samples showed excellent correlations. 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.
