BRITISH COLUMBIA Diamond drilling on the southern portion of the Ridge tungsten zone above the Max molybdenum mine has intersected “significant” intervals and grades of tungsten mineralization, according to the owner, ROCA MINES of Vancouver. The Max project near Revelstoke reached commercial rates of production in April 2008. The intersections were cut approximately 650 metres above the Main haulage adit of the mine.
The best assays came from hole No.7: 13.10 metres at 0.400% W (0.504% WO3) and 3.55 metres at 0.330% W (0.0416% WO3). The second intersection included the highest grade recorded, 0.708% W (0.893% WO3) over a 1.18-metre section. Additional assay results from three other successful drill holes are available at www.RocaMines.com.
Roca says the continuity of the mineralized zones indicated by drilling and the sizeable footprint of the mineralization on surface suggests the potential for a large-scale tungsten resource above the Max mine. More diamond drilling to assess the tungsten resource, obtain metallurgical samples, and possible near-term development with an underground raise are currently being planned. Existing infrastructure at the Max mine is well suited to the potential development of a tungsten resource, the company added.
