The reverse circulation assays are significantly higher than expected, including 29 metres 0.75% WO3 from 48 metres on the north-western flank.
Three of the reported assay results are above 1% and almost 50% of the results are greater than the average grade of the orebody.
"These are exceptional results in the north-western part of the Régua orebody and it is great to receive them in the lead up to the trial mine development,” said chairman Michael Masterman.
“The orebody remains open at depth and in all directions. Specifically, the zones to the northwest are indicating significant width and grade and are highly prospective for mine extension drilling.
Meanwhile, at La Parrilla, W Resources has been running its existing older concentrator for production of tungsten and tin. The plant is currently being modified to allow pilot runs and testing of the upgraded large-scale concentrator plant circuit to greatly assist in commissioning and ramp-up of the new large-scale concentrator plant.
