Mineralization occurs mainly in and at the periphery of dikes and stocks of early Tertiary-age quartz monzonite and hornblende diorite; silicification, propylitic and argillic alteration, hornfelsing near the intrusion. First located in 1972; considerable geochemical surveys, trenching, and sampling; 22 diamond-drill holes. From 19771996, 27 diamond-drill and 21 reverse-circulation holes, mostly for gold. Drilled for molybdenum in 2007; best intercepts in 4 drill holes included 250 ft of 0.048 percent molybdenum, 750 ft of 0.044 percent molybdenum, 250 ft of 0.0361 percent molybdenum, and 352 ft of 0.0434 percent molybdenum. Drilled another 10 holes in 2008; best hole cut quartz-pyrite-molybdenite mineralization for 536 ft that averaged 0.048 percent molybdenum. No reserves.
