Discussion

A prospect shaft exposed thin veins of spar. The pit was dug to 70 feet deep along a fault striking N55°W and dipping 80°SE (Weller et al. 1952). Unfortunately, Weller et al. (1952) did not plot this prospect on the geologic map that accompanies their report. We suspect that this prospect is close to the northeast-trending fault at the Knox and Rose Creek Mines, which intersects a northwest-striking fault mapped by Baxter et al. (1967).
