The new licence, Villa Seca, covers the initial mining areas in the Régua deposit over an area of 4.74sq km.
A conceptual mine study on the project was carried out in 2013 and the trial mining licence will allow W to continue with drilling, metallurgy testing and to commence initial mining.
Régua has a JORC compliant resource from 2008 of 4.46mln tonnes grading 0.308% WO3 (tungsten). The deposit has not previously been mined and has good infrastructure and road access, W said.
Michael Masterman, W Resources’ chairman, said: "The Régua trial mining licence grant is a tangible milestone for the project and the company is now well positioned to advance towards the feasibility study and initial mining and tungsten production."
W Resources recently started tailings processing at La Parrilla, where it is also developing a new tungsten mine.
