Comments

Comment (Development): 5 DRILL HOLES TOTALLING 5549 FT (1981)

Comment (Geology): 2 CENTERS OF INTRUSION AND MINERALIZATION. MO-RICH AREA ASSOCIATED WITH MORE SILICIC ROCKS.

Comment (Location): HEADWATERS OF BOBCAT GULCH ; INFO FROM LAND.ST :1978

Comment (Exploration): Drilling 1979-1981 indicated two distinct porphyry copper stocks The majority of work centered on a the eastern stock, on which a resource of 60,000,000 tons of .5% Cu was reported. Exploration of the western stock has identified a chalcocite enrichment zone that encompasses an area of at least 2,500 by 4,500 ft. BHP Minerals was exploring the property in 1994 an believed it has potential mostly for gold. The property adjoins on the northeast the Beartrack deposit with reserves of 36.9 million tons averaging .055 opt gold
