DRILLING COMPLETED AT KIZILCUKUR

A strong set of results from the Kizilcukur drilling programme

Ariana Resources plc ("Ariana" or "the Company"), the AIM-listed mineral exploration and development company with gold mining interests in Europe, is pleased to announce positive results from a recent drilling programme at the Kizilcukur Project ("Kizilcukur" or "the Project") of the Kiziltepe Sector. Kizilcukur is part of 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:

●     Resource infill and extension drilling programme has been completed, testing all three main zones of mineralisation, identifying potential extension zones.

●     Initial results of drilling include:

6.0m @ 4.75g/t Au + 135.2g/t Ag

7.3m @ 2.43g/t Au + 36.3g/t Ag

4.5m @ 3.76g/t Au + 17.7g/t Ag

●     Process metallurgical testwork of the Kizilcukur mineralisation yields an average gold recovery of 97%, significantly higher than Kiziltepe.

●     A rock-chip sampling programme designed to test the extensions to outcropping zones returned grades up to 15.47g/t Au.

●     Re-analysis of historic core samples confirms the historic gold grades.

Dr. Kerim Sener, Managing Director, commented:

"This is a great set of results from the Kizilcukur drilling programme. The vein system has now been sufficiently well tested for the Zenit mining team and the incoming data is continuing to demonstrate the continuity of gold and silver mineralisation in many of the areas tested. The Zenit team have commenced the detailed work to bring Kizilcukur into the Kiziltepe Sector mining plan. 

"At this stage, we are confident that Kizilcukur will yield a small, high-grade resource capable of being converted to a reserve, which will augment the ongoing operations at Kiziltepe. Metallurgically the ore performs very well with exceptionally high gold recovery, which is in part the result of nuggety free-gold. We expect Kizilcukur will be operated as a satellite mine to Kiziltepe within the next eighteen months."

Drilling Programme

This drilling programme was designed to increase the confidence in the resource, and upgrade the classification, in addition to further testing along known mineralised structures, both at depth and along strike (Figure 1). In particular, the vein systems at Ziya and Zafer were targeted, which had previously received only limited drill testing. In addition, in-fill drilling at depth and along strike was completed at the Zeki main vein system.

From the end of July through to November 2023, Ariana and Zenit exploration teams completed the HQ diamond drilling programme of 56 holes, totalling 3,563.8m. At the peak of the programme, two drill rigs were operating simultaneously. The average depth for all drilling was approximately 63 metres, with a minimum depth of 28.6 meters and a maximum depth of 118.8 metres. The dip angles were planned from 45° to 77° to test the extents of the mineralisation.

The drilling programme also highlighted the complex multi-phase mineralisation characteristic of the Kizilcukur deposit (Figure 2). Three different mineralisation phases have been identified and will be evaluated following the receipt of all assay results. These represent epithermal quartz veins, manganese rich zones, and a deeper sulphidic lead and zinc zone, which are suggestive of a low to intermediate sulphidation type system.

Figure 2: An example of the mineralised zones seen at Kizilcukur.

A total of 90.30m drill core from 5 selected historic drill holes have been re-analysed for gold, silver and multi-elements to check the results, which all returned results within reasonable confidence intervals. The results of the highest grade re-analysed zone are seen below in Table 2. Photon assay is being considered as a check analysis for core samples as a potential nugget effect has been noted.

Metallurgical Testwork

Two HQ diamond holes were drilled to twin the best representative mineralisation intervals of the 2015 RC and 2019 diamond drilling programmes. The whole core representing 2.90m and 3.20m were sampled with average grades of 5.17g/t and 2.20g/t Au, respectively. Both samples were crushed and sieved to -106 micron and subjected to NaCN leach tests. The average recovery of gold was 97%, following 72 hours leach time. Silver showed recoveries of up to 75% after 72 hours.

Rock-chip Sampling

A total of 66 rock-chip samples were collected to sample the untested subparallel and extensional zones of the known Kizilcukur vein system (Figure 3). The highest gold grade from this sampling programme is 15.47g/t, proving that the new zones are potential targets for further gold mineralisation and will be used to define new drill targets. Areas to the NW of Zeki and to the SE of Zafer, in addition to a parallel vein system to Ziya, are of particular interest.

Project Summary

The Kizilcukur Project consists of one operational licence located in Balikesir Province in Western Turkey. The property lies 22km to the northeast (straight line) and 70km by road from the Kiziltepe Mine. The Kizilcukur Project is one of the 3 satellite projects which have been sold to Zenit (see announcement of 2 December 2020).

The Project covers an area containing a series of sub-parallel quartz veins hosted by ophiolitic (dominantly basaltic) units that trend northwest and extend for about two kilometres. The veins exhibit classic low-sulfidation epithermal textures and attain a maximum true width of 8m. The Zeki Vein extends over a strike length of 820m. Composite rock-chip sampling of 80m strike along this quartz vein returned encouraging assay results of 6m at 3.3g/t Au, 2m at 9.6g/t Au and 1m at 7.2g/t Au prior to drill testing. The peak rock-chip assay result in this area was 152g/t Au and 1,320g/t Ag, suggesting the potential for substantial near-surface enrichment.

The Mineral Resource Estimate for Kizilcukur is c. 21,100oz gold (Au) and 0.62Moz silver (Ag) contained metal on three main veins (see announcement of 11 May 2020). 85% of the tonnage is in Measured and Indicated (M+I) categories: 218,317t @ 2.72g/t Au and 77.04g/t Ag. 46% of the M+I tonnage is located within the higher-grade Zeki Main Vein, with a grade of 3.62g/t Au and 82.54g/t Ag, upon which trial mining operations have been undertaken previously.

Trial mining was completed within the central part of the Zeki Pit in 2017. This pit is the largest and highest grade of the three pits defined following Whittle optimisation of the Kizilcukur resource in 2016. The General Directorate of Mining Affairs approved blasting operations on the licence as part of the Mining Permit (see announcement of 18 November 2015).

Sampling and Assaying Procedures

All diamond drill core is currently being processed at the Kiziltepe mine site and analysed at the Kiziltepe Mine Laboratory ("KML"). Results are assessed systematically and are grouped according to project.

HQ-size drill-core samples from the drilling programme at Kizilcukur were cut in half by a diamond saw and sent for analysis in batches in line with the Company's quality control procedures. Core recovery for all drilling conducted at Kizilcukur during this campaign was 90%. A total of 3,621 samples (including 762 QA/QC samples) were submitted to KML, of which results for 1,615 samples have been received. Samples to be sent to ALS Global, Izmir as an external laboratory check to add confidence to KML results, have been selected and are awaiting dispatch.

QA/QC sample insertion rates vary depending on the batch size accepted by the laboratory. Ariana sampling protocol requires insertion of 4 QA/QC samples per batch to include 1 blank, 1 CRM, 1 field duplicate and 1 pulp duplicate to assess the accuracy and precision of all stages of the sampling and analysis. During this drilling programme, Zenit QA/QC protocol required 1 blank, 1 CRM, 1 field duplicate, and 1 pulp duplicate per batch of 19 samples and over 10% samples analysed at external laboratory.

Between 2020 and 2021, KML has undergone an extensive expansion to meet the significant demands for sample assaying, from both the mining and exploration teams. This expansion is complete with the onsite laboratory, now housing seven furnaces, two ICP-OES instruments, two Atomic Absorption spectrometers (AAS), three drying ovens, three crushers and three pulverisers. The laboratory upgrades have allowed for a doubling of sampling throughput (70 samples per day to 135). The two major upgrades for 2021 included the addition of 1) a multi-element ICP-OES (Perkin Elmer Avio 550) analyser, and 2) an Elementrac CS-I sulphur-carbon analyser. The ICP-OES provides the team with a full suite of elements on selected samples (as opposed to just gold and silver).

However, new operating procedures are currently being internally reviewed and calibrations of the new instruments are being assessed. As part of this, the laboratory team are sending in excess of 10% of their crushed rejects from selected drill core samples to ALS Global in Izmir for check assays. Zenit's internal QA/QC data and sample duplicates have been reviewed, and are considered approved for Ariana's reporting purposes. In addition, since October 2022 KML has been accredited by the Turkish Accreditation Agency (TÜRKAK) with 'TS EN ISO/IEC 17025:2017 General Requirements for the Competence of Experimental and Calibration Laboratory.'

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. Zenit maintains an archive of half-core samples and a photographic record of all cores for future reference.
