AIM: AAU
HIZARLIYAYLA DISCOVERY DRILLING
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 the initial drilling results from the Hizarliyayla area of the Salinbas Project. The project is operated via 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:
· Initial exploration drilling results from Hizarliyayla have returned anomalous gold, silver and zinc including:
o 23.1m @ 0.34g/t Au + 2.83g/t Ag and 0.13% Zn
o 18.6m @ 0.22g/t Au + 1.18g/t Ag and 0.15% Zn
o 3m @ 0.88g/t Au + 37.97g/t Ag and 2.00% Zn
· Grade of precious metals broadly increases with the depth of penetration into the system, suggesting the potential for Hot Maden-type mineralisation at depths below 600m from surface.
· 2,548m of drilling completed to date with another c.3,000m of drilling planned.

"These are an impressive set of initial drilling results from the Hizarliyayla prospect. We have long suspected the potential of the Hizarliyayla area, since it was first systematically mapped by our team in 2017. Surface sampling undertaken since that time, including some of the brilliant new geological work by our team in 2022, continued to reaffirm our view that the mineralisation and alteration encountered at surface represented a high-level expression of a substantial hydrothermal system. Consequently, we recognised the requirement to undertake deep drilling of this prospect and these initial results continue to underpin this understanding.
Notably, Hizarliyayla is at an elevation of approximately 1,500m, whereas the high-grade gold zone of the Hot Maden deposit occurs 8km to the south at an elevation of about 900m. Interestingly, the grade of both gold and silver intercepted in the current drilling has a tendency to increase with depth, suggesting that the deeper we drill, the better the grade and perhaps increasing proximity to a high-grade gold zone akin to Hot Maden. The elevation difference noted here indicates that we may need to drill holes well over 600m deep in order to encounter a potential Hot Maden-type discovery. Despite the mineralised intercepts being typically fairly narrow and deep, these broader observations regarding the prospectivity make these some of the most exciting exploration drilling results that we have ever announced."

Drilling Programme
The Hizarliyayla Project is located 9km southwest of the Salinbas Project and about 8.5km north of the Hot Maden Au-Cu deposit. The area is defined by an area of approximately 1,500m by 800m of argillic to advanced-argillic alteration zone with pervasive disseminated pyrite, silica and minor gold from surface.
In 2017 (LSE announcement: 5 September 2017), the Ariana exploration team completed extensive surface mapping to 1:10,000 scale, pXRF soil, clay, and rock-chip sampling over the Hizarliyayla Project. This work was followed up in the Autumn of 2022 with further infill soil sampling, rock sampling for geochemistry, petrography and multi-sensor sample scanning, detailed geological, alteration and structural mapping supported by remote sensing studies; collectively leading to define the type of mineralisation and alteration zonation at Hizarliyayla. The collective results were used in late 2022 to plan Zenit's maiden diamond drilling programme at Hizarliyayla.
The original Hizarliyayla drilling programme consisted of up to 19 planned holes for approximately 4,000m (Figure 1), however, this is the subject of ongoing review based on results. Drilling commenced on the project in late December 2022, and to date, 5 drill holes have been completed for a total of 2,548m. Drilling is expected to continue at Hizarliyayla until mid-2023.
Figure 1: Map showing the drilling planned at Hizarliyayla, including the recently completed holes. Not all planned locations will be possible to drill during the current programme due to logistical aspects involving the steep topography.
Drill holes HZR001 to HZR005 have now been reviewed and sampled by the onsite geological team. The drill core observations have provided very encouraging results (Figure 2). Results of the geochemical analysis of the first three drill holes completed include (Table 1):
· HZR003 23.1m @ 0.34g/t Au + 2.83g/t Ag + 0.13% Zn from 182.3 metres
· HZR002 18.6m @ 0.22g/t Au + 1.18g/t Ag + 0.15% Zn from 187.9 metres
· HZR001 2.6m @ 0.21g/t Au + 4.45g/t Ag + 0.19% Zn from 253.6 metres
The mineralisation intercepted within the first two Hizarliyayla drill holes appears to represent the intermediate zone (Ag-Pb-Zn±Au) of an intermediate sulphidation epithermal system. These may be developed peripherally to a buried porphyry system (Figure 3). Further work is ongoing to better understand the wide mineralised system, and to ultimately target potential feeder zones, possibly akin to the Hot Maden copper-gold system (Figure 3).

The potentially most well-preserved system occurs at Hizarliyayla and future drilling will need to be planned accordingly.
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 the project.
HQ size drill-core samples from the drilling programme at Hizarliyayla 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 Hizarliyayla during this campaign was 91%, for a total of 1,122 measurements. A total of 2,938 samples (including 556 QA/QC samples) were submitted to KML, of which results for 1,596 samples have been received. The results for 70 samples (including 6 QA/QC samples) have been received from ALS Global, Izmir (further samples pending) as an external laboratory check to add confidence to KML results, particularly during laboratory expansion works.
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 including 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 the 2021-2023 drilling, Zenit QA/QC protocol required 1 blank, 1 CRM and 1 field duplicate and over 10% of samples were analysed at an external laboratory. The Zenit QA/QC protocol is under review by both Ariana and Zenit teams following the laboratory upgrade.
Between 2020 and 2021, KML underwent 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 greater 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, with c.9% of the Salinbas samples also analysed at ALS. 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. Multi-element ICP was used for copper, lead, molybdenum and zinc analyses. 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.
