Towers, Dalal Street, Mumbai. (BSE Scrip Code: 512068) Dear Sir, Sub: Encouraging drill results for Tungsten and Tin from Logrosan Project in Spain Ref: Disclosure under Regulation 30 of SEBI (Listing Obligations & Disclosure Requirements) Regulations, 2015. Deccan Gold Mines Limited (“Deccan Gold”) is pleased to inform Shareholders of encouraging results from the Logrosan Tungsten Project in Spain. Drilling of the Dehusa Tungsten-Tin target - one of several priority targets within the Logrosán multi-commodity project - commenced in mid-March 2026. To date, seven drill holes, LDD013 to LDD019, have been completed for a total of 2,984 m, while drill hole LDD020 is currently in progress. The completed holes have an average depth of approximately 430 m, with the deepest hole reaching 626 m. Every drill hole completed so far has intersected potentially economic tungsten or tungsten–tin mineralisation (Figure 1) that could support future underground mining. Laboratory analytical results received for drill holes LDD013, LDD015, LDD016 and LDD017 have confirmed the presence of high-grade tungsten mineralisation. Highest results include assays of 0.88% WO3 at 470 metres in LDD016 and 1.21% at 535 metres in LDD017. The widest intersection is in LDD016 which intersected a zone of 7.5m averaging 0.29% WO3. Significant intersections for all drill holes are listed in Table 1 and shown visually in Figure 2. All drill core is initially examined with a portable XRF device together with detailed visual inspection under ultraviolet light. This approach provides a preliminary assessment of tungsten mineralisation and optimises exploration budget, specifically for analysis costs. Portable XRF results and inspection of the remaining holes also shows multiple veins and mineralised zones. Full assay results for the programme are expected by mid-September. The presence of outcropping tungsten mineralisation, together with its confirmation at depth, suggests that mineralisation may extend along the central axis of the S- shaped Dehusa anomaly for approximately 3 km. This indicates substantial tungsten potential. Dehesa is one of several exploration targets within the wider Logrosán project. Drilling at the Las Brujas and Logrosán North targets is currently planned for October and November 2026. Figure 1: Scheelite (tungsten) mineralisation in Dehusa Deposit.

Forward looking statement Dr. Hanuma Prasad Modali, Managing Director, Deccan Gold Mines Ltd., said: “The results from Logrosan provide strong validation of the project's district-scale potential and reinforce our confidence in its long-term prospects. The fact that every drill hole has intersected potentially economic tungsten or tungsten-tin mineralisation points to a robust mineralised system with significant exploration upside. As the global focus on critical minerals continues to intensify, strategically important resources like tungsten will underpin future industrial growth and supply-chain resilience. Logrosan strengthens Deccan Gold's international critical minerals portfolio and advances our vision of building globally competitive mining assets that support long-term resource security and sustainable value creation”.

(“LMSL”) Spain, with the option to further increase its stake to 75% then potentially up to 95%. Our investment is being deployed towards exploration and development of mineral assets held by LMSL in Spain, including the granted 37km2 Logrosan and 40km2 Maria projects which lie in a highly mineralised region of Spain known for tungsten, tin, rare earth elements, and gold occurrences. An application to extend the Logrosan licence area by a further 30km2 has also been lodged. Logrosán lies within an Iberian metallogenic belt and is best understood as a district-scale, multi-commodity critical mineral cluster rather than a single-commodity prospect. The exploration model is vein- and greisen-style tungsten–tin mineralisation associated with a blind parent intrusion (Figure 3), with near-surface mineralisation representing only the upper part of a larger system that should intensify toward the intrusion cupola at depth. Figure 3: Logrosán exploration model and greenfield exploration results. Our partners in the Project have undertaken considerable greenfield exploration work over the granted 37 km2 licence area including ground magnetic surveys and a comprehensive soil sampling programme. The results of this work identified targets for tungsten(W), tin (Sn), phosphorous (P), REE, and Nb–Ta. Initial sub-surface testing was via a small RAB drilling programme over the areas prospective for tungsten (Figure 4). Promising near surface indications of tungsten mineralisation prompted further drilling, including the current programme, which has intersected multiple veins of potentially economic scheelite (tungsten) mineralisation. The primary Dehesa tungsten target (Figure 4) is defined by a strong, broadly isometric, S-shaped tungsten-in-soil anomaly covering approximately one square kilometre. Tungsten concentrations reach around 700 ppm in the central part of the anomaly. Widespread disseminated scheelite mineralisation and numerous fine scheelite-bearing veinlets are also observed outside the main mineralised zones. This indicates that drilling has intersected a broad tungsten-bearing hydrothermal system rather than a series of isolated veins and is consistent with the upper part of a greisen–vein system developed above a concealed 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 BSE DISCLOSURE granitic source. It supports the potential for additional, locally higher-grade zones within the wider mineralised envelope and at greater depth. Detailed surface investigation along the extension of the southern limb of the S-shaped tungsten-in-soil anomaly led to the discovery of outcropping scheelite mineralisation. Drill hole LDD019, drilled to a depth of approximately 260 m at an inclination of 45 degrees, confirmed the continuation of mineralisation at depth, although laboratory analytical results are still pending.
