Towers, Dalal Street, Mumbai. (BSE Scrip Code: 512068) Dear Sir, Sub: Preliminary modelling of Tungsten and Tin mineralisation in the 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 that we have received all results and geological data from the maiden drilling programme at our Logrosan Tungsten Project in Spain. As preciously informed, our maiden drilling focussed on the Dehesa Tungsten-Tin target - one of several priority targets within the Logrosán multi-commodity project. The drilling programme commenced in mid-March 2026, and eight holes were drilled for a total of 3522m. The holes have an average depth of approximately 430 m, with the deepest hole reaching 626 m. Every drill hole completed intersected potentially economic tungsten or tungsten–tin mineralisation that might support future underground mining. Preliminary geological modelling (Figure 1) suggests the deposit might contain more than 2.3Mt containing more than 2,000 t WO and 500 t SnO at economic cut-off grades. Mineralised intersections are indicative of second-order structures off a primary intrusive system. Over the coming weeks, we will be closely interrogating the data and model to select the location and orientation of future drillholes aimed to intersect the primary mineralisation structures feed the Dehesa deposit.

To date, 3 holes have intersected antimony mineralisation (>820m). Assay results are pending.  Our partners in the Logrosan Project recently applied for funding under an exploration incentive scheme run by the Spanish Government. We are please to report that the Government will provide up to 250,000 Euro in deductions for specific administration and exploration costs related to the La Brujas exploration, the second significant WO3 target at Logrosan (Figure 3). Our exploration programme at La Brujas will commence in November / December once the first phase of drilling at Maria Prospect has finished. Forward looking statement Dr. Hanuma Prasad Modali, Managing Director, Deccan Gold Mines Ltd., said: “The maiden drilling results from Logrosán are encouraging, particularly because every completed hole has intersected tungsten or tungsten–tin mineralisation. The preliminary geological model gives us a stronger basis to understand the scale and architecture of the mineralised system and to plan the next phase of exploration.” “However, there is still significant technical work ahead to establish the extent, continuity and economic potential of the deposit. Our focus now is on using the data to guide the next drilling programme and systematically evaluate the opportunity. At a time when critical minerals are becoming increasingly important to industrial competitiveness and supply-chain resilience, Logrosán represents a promising component of Deccan Gold’s growing international portfolio,” added Dr. Hanuma About Logrosán Tungsten Project Shareholders will recall that the Company (through its wholly owned Dubai subsidiary, DGFZCO) has entered a definitive Earn‑In / Option and Shareholders Agreement to acquire a 51% stake in Logrosan Minera S.L. (“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 2), with near-surface mineralisation representing only the upper part of a larger system that should intensify toward the intrusion cupola at depth.

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 3). 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 3) 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 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. Tungsten and tin grades are expected to increase with depth as the system approaches the inferred granitic source, although this interpretation will require confirmation through deeper drilling. The depth to the blind intrusion is currently estimated at approximately 1,500–2,000 m.
