Comments on the geologic information

  • Geologic Description = The property is near a thrust fault in lower Paleozoic metamorphic rocks between two masses of the Devonian(?) granitic Baby Creek batholith (DeYoung, 1978). No description of the occurrence is available. DeYoung (1978) noted that six claims were located in 1975 and listed the commodities of interest as Au and As. The U.S. Bureau of Mines, however, lists the commodities of interest as unspecified Cu and Mo sulfides and by-product As (Maas, 1987). As a Cu-Mo occurrence, the property is interesting because it is near the Geroe Creek porphyry prospect (CH053).
  • Ore Material = Unspecified copper
  • Ore Material = an unspecified arsenic mineral
