Towers, Dalal Street, Mumbai. (BSE Scrip Code: 512068) Dear Sir, Sub: Preliminary geological modelling of the Bhalukona Ni-Cu-PGE deposits, Chhattisgarh Ref: Disclosure under Regulation 30 of SEBI (Listing Obligations & Disclosure Requirements) Regulations, 2015. Deccan Gold Mines Limited (“Deccan Gold”) is pleased to inform Shareholders that preliminary modelling of exploration drilling data (Figure 1) suggests the Bhalukona Ni-Cu-PGE deposit contains over 4Mt of potentially economic ore grading around 0.24% of Ni-equivalent grade (i.e. the weighted sum of Ni, Cu, Pt and Pd grades) summing to more 10,000t of nickel- equivalent metal. The estimated tonnes only include the near surface mineralisation and barely cover 25% (300-350m) of the 1.3km mineralised corridor we have identified at Bhalukona. The modelling also does not include potential repetitions of the sequence to the SE as suggested by drone magnetic and IP surveys. It is important to note that these figures are preliminary exploration-stage interpretations and do not constitute a defined mineral resource or reserve, however, they provide valuable information and strategic direction for our exploration team.

Bhalukona is an encouraging milestone in our effort to unlock India's domestic critical-mineral potential. The preliminary modelling points to a promising nickel-copper-PGE system, with the current estimates covering only a fraction of the identified mineralised corridor. India's resource security will depend on our ability to discover and responsibly develop strategic mineral resources at home. Our focus is to advance Bhalukona through science-led exploration, technical rigour, and long-term commitment, contributing to a stronger domestic mining ecosystem and more resilient critical-mineral supply chains.” About Bhalukona Ni-Cu-PGE Composite Licence Deccan Gold was privileged to be one of the very first companies to be granted a nickel licence in India when the Government of Chhattisgarh executed the Bhalukona-Jamnidih Composite Licence in favour of the Company on 01 April 2025. The execution of the Bhalukona nickel licence was an exciting and significant step in Deccan Gold’s mission to make Atmanirbhar Bharat a reality, and secure supply of strategic and critical minerals for India and our ~50,000 Indian Shareholders. The 30 sq. km Bhalukona Nickel Block is in Basana Tehsil, Mahasamund District, Chhattisgarh State (Figure 2) and readily accessed via local roads and forestry tracks. Deccan Gold has acquired the necessary forestry approvals for non-destructive exploration activities up to and including drilling in specific areas. Figure 2: Location of the Bhalukona–Jamnidih Ni–Cr–PGE Composite Licence (CL-51) and corner coordinates In the nineteen months since, DGML has carried out a staged, technically sequenced exploration programme covering the whole 30 sq. km block: a drone magnetic and LiDAR survey, deep IP, 2D electrical resistivity tomography (ERT), 1:5,000 and 1:2,000 geological mapping, rock-chip and channel geochemistry, bulk sampling for beneficiation studies and, since March 2026, a 15 hole, 2773m diamond core drilling (Figure 3). This work has confirmed a layered mafic–ultramafic intrusion hosting Ni–Cu–PGE sulphide mineralisation, from disseminated sulphides up to heavy/massive sulphide lenses (Figure 4). Drillholes have identified a 100+m wide corridor along an DECCAN GOLD MINES LIMITED (CIN: L51900MH1984PLC034662) Registered Office - 501, Ackruti Trade Center, Road No.7, MIDC, Andheri (East), Mumbai – 400 093, Maharashtra www.deccangoldmines.com info@deccangoldmines.com Page | 2 Corporate Office & Correspondence Address No. 77, 16th Cross, Sector-IV, HSR Layout, Bengaluru – 560 102 +918047762900 +918047762901 approximately 1.3 km long zone to depths of over 200m (Figure 5. The corridor contains multiple zones of potentially economic nickel, copper and palladium mineralisation, with localised occurrences of platinum. Most drillholes contain various widths of disseminated and heavy-massive sulphide mineralization. Available results are tabulated in Table 1. Sulphide minerals appear predominantly pyrrhotite (Ni), pentlandite (Ni), and chalcopyrite (Cu). Magnetic surveys also indicated that there may be repetitions of this zone under soil cover in the east of the license.
