The first four holes on the Cuatro Hermanos copper-molybdenum project in Sonora state, Mexico, have intersected significant molybdenum mineralization along with low-grade copper.
Virgin Metals (VGM-V), which is doing 6,000 metres of reverse-circulation drilling on the prospect, put four holes on the Sulphate Zone prospect, near the contact between a volcanic complex and a quartz-diorite porphyry intrusion. The four holes tested an area about 500 metres by 350 metres in size.
Three vertical holes intersected 168 metres grading 0.032% molybdenum and 0.2% copper, 122 metres grading 0.042% molybdenum and 0.26% copper, and 131 metres of 0.11% molybdenum and 0.2% copper. An inclined hole graded 0.114% molybdenum and 0.29% copper over a 56.4-metre drilled length, equivalent to a true thickness of 45.5 metres.
Assay results are pending on a fifth hole in the area.
Three more holes are complete on the Main Zone, about 700 metres to the south of the Sulphate Zone, and drill cuttings are out at the laboratory. Another hole on the Main Zone is in progress.
