As announced in the material event disclosures dated July 19, 2024 and June 11, 2025, developments regarding the reserve determination studies were publicly shared.

In this regard, within the scope of the exploration activities conducted by Erdemir Madencilik Sanayi ve Ticaret A.Ş. (Ermaden), a subsidiary of Ereğli Demir ve Çelik Fabrikaları T.A.Ş., in the Alacahan Village area of Kangal District, Sivas Province, an "Inferred Resource" level of gold mineralization has been identified. This estimation has been prepared in compliance with the UMREK (National Resources and Reserves Reporting Committee) and JORC (Australasian Joint Ore Reserves Committee) reporting standards.

The license area covers 5,804.08 hectares, of which 45 hectares have been explored to date. A total of 360 core drillings have been carried out, reaching a cumulative drilling length of 96,649 meters. From these drillings, 96,533 fire assay results have been obtained.

The Inferred Mineral Resource Estimate, obtained as a result of modeling in accordance with UMREK and JORC standards, is presented as follows:

Category
Tonnage (Mt)
Grade (g/t Au)
Contained Metal (oz Au)
Inferred Resource
14.9 0.89 424,000

The calculations were made based on a 0.5 g/t gold cut-off grade, and approximately 424,000 ounces of gold content were identified in 14.9 million tonnes of ore with an average gold grade of 0.89 g/t gold. The average density was determined as 2.53 g/cm³, and quality assurance and quality control (QA/QC) procedures were conducted in accordance with international standards. All assays were performed at the Bureau Veritas Ankara Laboratory.

Exploration activities at the Alacahan site are ongoing both within the currently modeled area and in potential zones where drilling has not yet been conducted. Infill drilling within the defined mineralized zone is continuing, and upon completion of these works, this portion is intended to be upgraded to a higher confidence category suitable for inclusion in future reserve calculations. Concurrently, core drilling programs have been planned and initiated in other areas of the site to support new discoveries and resource expansion. Within this framework , the objective is to determine the overall resource potential of the Alacahan site and, in the longer term, to expand the mineral resource base.

This study has been independently prepared by Competent Persons Ruth Woodcock (UMREK N 252, EurGeol N 1715) and Jörg Pohl (EurGeol N 1728) in accordance with the principles of transparency, accuracy, and reliability outlined in the UMREK 2023 and JORC 2012 codes, and has been approved by Westech International Ltd.

The information presented in this announcement relates to an Inferred Resource and does not constitute an economically mineable reserve. Following infill drilling and ongoing resource expansion activities, it is planned that the resource classification will be updated based on new data, and to proceed with feasibility studies for reserve estimation.

Further developments will be made available to the public.

In contradiction between the Turkish and English versions of this public disclosure, the Turkish version shall prevail.
