As of 2013, 169 drill holes (>57,800 m) delineating near surface porphyry copper targets at 4 of 14 known areas (90% of intercepts >0.3% Cu Eq.). Near-surface zones ( within 0.550 m of the surface) of variable chalcocite enrichment grading into chalcopyrite-rich and into chalcopyrite-bornite-magnetite mineralization.
