Abstract

The mineral resource potential of the Blackjack Springs Wilderness in the Nicolet National Forest, Vilas County, Wisc., was evaluated in 1982.  No bedrock exposures are known in or near the wilderness.  Geophysical data and regional geologic relations suggest that the area consists mostly of recrystallized and deformed mafic volcanic rocks and associated mafic intrusives of Early Proterozoic age.  The only identified mineral resources in the Blackjack Springs Wilderness are sand and gravel, but these commodities are abundant regionally.  While the occurrence of stratabound massive-sulfide (cooper-zinc-lead) and (or) magmatic sulfide (copper and (or) nickel)-type deposits are possible in the wilderness, their occurrence is not probable.
