Towers, Dalal Street, Mumbai. (BSE Scrip Code: 512068) Dear Sir, Sub: First gold doré at Altyn Tor Project, Kyrgyzstan Ref: Disclosure under Regulation 30 of SEBI (Listing Obligations & Disclosure Requirements) Regulations, 2015. Deccan Gold Mines Limited (“Deccan Gold”) is delighted to inform Shareholders that your Company has successfully taken the next step in its transition from explorer to producer with the production of our first gold doré at Altyn Tor today. For the first time, a batch of gravity circuit concentrate was processed through the newly installed Intensive Leach System (ILS) tanks for a proof-of-concept run (Figure 1). Gold was recovered from the pregnant leach solution via the Merrill-Crowe process then smelted to produce doré. The aim of the first batch was to evaluate the integrated process design and to validate parameters under active field conditions. The outcome confirms the metallurgical leachability of the material, successfully translating the high recovery rates established in earlier laboratory test work into the production environment. This milestone represents a critical de-risking step for the processing flowsheet and demonstrates operational viability as we advance toward full-scale commercialisation.

Forward looking statement Dr. Hanuma Prasad Modali, Managing Director, Deccan Gold Mines Ltd., said: “The successful production of our first gold doré at Altyn Tor marks a defining milestone in Deccan Gold's journey as we transition from an explorer to a gold producer. Successfully validating the complete processing flowsheet—from gravity concentration and intensive leaching through to gold recovery and doré production—under live operating conditions significantly de-risks the project and provides confidence in its commercial potential.

It reinforces our confidence in the upgraded processing plant and our strategy of building a globally diversified portfolio of producing gold and critical mineral assets. As we continue to advance Altyn Tor towards full-scale production, we remain focused on unlocking additional resource potential and creating long-term value for our shareholders”. About Altyn Tor Deccan Golds 60% holding in Avelum Partners LLC, developer and operator of the Altyn Tor Gold Project, marks the first investment by an Indian mining and exploration company in Kyrgyzstan and is expected to enhance economic ties between the 2 countries. Altyn Tor is in the Naryn region of central Kyrgyzstan, approximately six hours by road from the capital Bishkek. The deposit forms part of the highly mineralized Soltan Sary mineralization zone, which extends over 300km length and is part of the major Tien Shen Shear Zone, host to numerous world-class gold deposits. Gold mineralization is hosted in quartz, quartz- carbonate veins and stockworks. Current mineral resources at the Project are estimated to contain 180 koz (5.6t) of gold. Mining at Altyn Tor commenced in 1993 by the State-owned, Kyrgyzaltyn OJSC. The mine produced approximately 2,200 kg of gold before its temporary closure in 2022. In that year, Avelum entered into a simple agreement with Kyrgyzaltyn to develop and operate the mine. A 2023 feasibility study demonstrated the viability of increasing gold recovery through the addition of a leaching circuit and expanding the existing open pit mine. Currently, Avelum is upgrading and expanding the processing plant capacity to include a gravity and leaching circuit. Concurrently, drilling programmes have demonstrated that the current mineral resource understates the true size of the deposit significantly. Recent drilling has shown extensions of the deposit to the west and below the current pit design. The high-grade intersections below the pit design could support a future underground mining, subject to further drilling planned in 2026 onwards. Deccan Gold will update the mineral resources and develop a revised life-of-mine plan. The results of this work will be presented to the Kyrgyzstan Committee of State Reserves for authorisation to increase the life of the operation.
