Ariana Resources plc Provides Update on Drilling Results from Main and South Zones At Tav San Mine
Ariana Resources plc provideD the following summary of the ongoing drilling programme at Tavsan Mine, western Türkiye (23.5% owned by Ariana). Highlights: Following on from the announcement on13 November 2025of high-grade gold in drilling results from the North at Tavsan Mine, this announcement covers the assay results received from the 85-hole programme at Tavsan Main Zone and South Zone; The drilling on the Main and South Zones identified resource expansion opportunities and completed infill drilling; Results include the following best intercepts: 15.7m @ 1.51g/t Au + 7.82g/t Ag from surface (TAV-D014-25), 7.4m @ 2.76g/t Au + 3.10g/t Ag from 16.9 metres (TAV-D030A-25), 9.7m @ 1.91g/t Au + 3.27g/t Ag from 0.8 metres (TAV-D079-25); Drilling is continuing in other areas across the West and East Zones of the Tavsan Mine; The latest drilling highlights significant potential for growth at the South Zone, with a significant area remaining untested; A JORC Resource update will be completed at the end of the 15,000m programme at Tavsan, expected in Second Quarter 2026. Tavsan Main and South Zone Drilling: Since the start of drilling at Tavsan in early 2025, over 9,991m of HQ diamond drilling had been completed by November 2025. Of this, 3,887m was drilled across 85 holes in the Main and South Zones, the assay results for which are reported herein. A further 5,345m was completed across 71 holes at the North Zone as announced on 13 November 2025. Drilling continues, with results pending for other areas of the Tavsan Mine. Drilling has included infill holes to aid mine planning, and also holes around the periphery of the currently defined resources, with mineralisation now confirmed to extend beyond the current resource outlines, both at depth and along strike. Tavsan contains a JORC 2012 Measured, Indicated and Inferred Resource of 7.65Mt at 1.26g/t Au for 311,000oz Au and 1.1Moz Ag. A resource update will be completed at the end of the drilling programme, currently expected in Second Quarter 2026. An area of particular interest within South Zone is drill hole TAV-D096-25, which, from a depth of 26 metres, intercepted 12.1m @ 1.45g/t Au. This hole was drilled on the southernmost edge of modelled mineralisation, and indicates significant potential to extend mineralisation and expand the Resource. Furthermore, drilling on the easternmost extents of Main Zone intercepted the primary mineralised horizon from surface as expected (TAV-D14-25 15.7m @ 1.51g/t Au + 7.82g/t Ag); but more importantly, a deeper zone of mineralisation was also intercepted from 26 metres. This second zone is interestingly rich in both gold and high silver (TAV-D14-25 7.5m @ 1.51g/t Au + 485g/t Ag), and presents a new exploration opportunity for future drilling. Key intercepts to date include: 15.7m @ 1.51g/t Au + 7.82g/t Ag in TAV-D014-25 from surface (Main Zone); 7.4m @ 2.76g/t Au + 3.10g/t Ag in TAV-D030A-25 from 16.9m (Main Zone); 9.7m @ 1.91g/t Au + 3.27g/t Ag in TAV-D079-25 from 0.8m (South Zone); 10.6m @ 1.71g/t Au + 3.62g/t Ag in TAV-D101-25 from 3.0m (South Zone); 12.1m @1.45g/t Au + 2.86g/t Ag in TAV-D096-25 from 26.0m (South Zone); 5.9m @ 2.84g/t Au + 4.04g/t Ag in TAV-D073-25 from 18.9m (South Zone). The infill drilling in Main Zone has confirmed the continuity of the high-grade domain, as previously modelled. Gaps in the previous model have also been drilled and have intercepted mineralisation at the expected depths. Significant gold intercepts were calculated for the 2025 Tavsan drilling using a 0.5g/t Au minimum cut-off and allowing for up to 1m internal dilution. Intercepts were calculated using Kiziltepe Mine Laboratory ("KML") data. Sampling and Assaying Procedures: All diamond drill core from Tavsan has been logged and sampled at the Tavsan Mine site and analysed at the Kiziltepe Mine Laboratory ("KML"), where results are assessed systematically. HQ-size drill-core samples from the drilling programme at Tavsan 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 Tavsan during this 2025 campaign was 88%. From this part of the programme, a total of 2,593 sample results for 2,036 metres of sampled drill core have been returned from the KML (including 545 QA/QC samples). Samples are also being analysed by ALS Global in Izmir as an external laboratory check as part of the QA/QC procedures used for the project, with a minimum 10% check rate to be achieved by the end of the drilling programme. QA/QC sample insertion rates vary depending on the batch size accepted by the laboratory. During the 2021-2025 drilling, Zenit QA/QC protocol required 1 blank, 1 CRM, 1 field duplicate, 1 pulp duplicate and over 10% samples analysed at an external laboratory. 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 analyses of other elements. Reviews of the assay results have determined that all Quality Control and Quality Assurance samples (blanks, standards, field duplicates and pulp 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.
