Deccan Gold Mines Ltd, an Indian-listed gold and critical-minerals exploration company, has reported encouraging results from its maiden drilling programme at the Dehesa tungsten-tin target within the Logrosán project in Spain.
All eight completed drill holes intersected tungsten or tungsten-tin mineralisation, providing a basis for further exploration and assessment of the project’s geological potential.
Preliminary model indicates mineralisation
Preliminary geological modelling suggests the deposit could contain more than 2.3 million tonnes of mineralised material, including over 2,000 tonnes of tungsten trioxide (WO₃) and 500 tonnes of tin oxide (SnO₂) at the modelled economic cut-off grades.
The company cautioned that these figures are preliminary exploration-stage interpretations and do not constitute a defined mineral resource or reserve.
Further drilling to assess potential
The drilling programme began in March 2026 and covered 3,522 metres across eight holes. The holes averaged approximately 440 metres in depth, with the deepest reaching 626 metres.
Geological interpretation suggests the mineralisation could be part of a broader hydrothermal system associated with an underlying intrusive body. The company and its technical partners are reviewing the drilling data and geological model to determine the location and orientation of future drill holes.
Management comment
“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,” Deccan Gold Mines Ltd, Managing Director, Hanuma Prasad Modali, said.
He said further technical work was required to establish the deposit’s extent, continuity and economic potential. The next phase will focus on using the data to guide drilling and evaluate the system at greater depth.
Exploration expands to other targets
Drilling is also continuing at the nearby Maria prospect, where all three completed holes have intersected antimony mineralisation over a combined drilled length of more than 820 metres. Assay results are awaited.
The company’s partners have secured Spanish government support through an exploration incentive scheme, offering up to €250,000 in deductions for specified administrative and exploration costs associated with the La Brujas tungsten target.
Exploration at La Brujas is planned to begin after completion of the initial Maria drilling phase. The activities form part of Deccan Gold’s effort to evaluate multiple mineral targets across the Logrosán project.
