Reference information

Comments Chip samples: 7600 ppm Mo, 5460 ppm Cu; drill hole intersection 10 m at 12 g/t Au, 17 g/t Ag, 2.0% Cu. Rhenium in molybdenite 0.12 to 4.12%. The prospect is hosted in Tertiary porphyritic microgranite. Three hydrothermal alteration zones have been recognized in the porphyritic microgranite: argillic, phyllic, and propylitic.
