|Location and accuracy||The Sure Shot prospect is at an elevation of about 3,900 feet, 1.5 miles south of VABM 5896 (Way). The map site is in the NW1/4 of sec. 18, T. 22 S., R. 1 E., of the Fairbanks Meridian. The location is accurate to within 1,000 feet. This is location 39 of Clark and Cobb (1972), location B-14 of Balen (1990: OFR 34-90).|
Geologic descriptionThe country rocks in the area of the Sure Shot prospect consist of a 2,000-meter-thick sequence of Lower Permian? and Pennsylvanian, volcanic rocks, massive volcanic flows, breccias, and subordinate volcaniclastic rocks, all largely andesitic in composition (Wilson and others, 1998). The prospect consists of pyrite and chalcopyrite disseminated in the volcanic rocks. Samples contain 4 ppb gold and 153 ppm copper (Balen, 1990 OFR 34-90).
|Geologic map unit||(-147.641253073637, 63.0105473542673)|
|Mineral deposit model||Cyprus massive sulfide (Cox and Singer, 1986; model 24a)|
|Mineral deposit model number||24a|
|Age of mineralization||The sulfide minerals probably are syngenetic with their Lower Permian - Pennsylvanian host rocks.|
|Workings or exploration||Surface samples only. Samples contain 4 ppb gold and 153 ppm copper (Balen, 1990 OFR 34-90).|
|Indication of production||None|
