| Location and accuracy | Prospect is on the north-facing slope above the eastern tributary of Miners River, about 1.1 miles west of Kadin Lake. Accurate within 1 mile. Locality A-8 of Jansons and others (1984) and locality 72 of Hoekzema (1984). |
Geologic descriptionTwo mineralized shear zones in conglomerate of the Early Tertiary Orca Group range from 5 to 100 ft wide and contain sulfide veinlets and pods of chalcopyrite and pyrite. Five chip samples contained from 20 ppm to 3 percent Cu and 2.6 to 46 ppm Ag. Four grab samples contained from 195 ppm to 0.94 percent Cu, 2.7 to 8.8 ppm Ag, and 9 ppm to 0.18 percent Ni (Jansons and others, 1984). | |

| Age of mineralization | Paleocene or younger based on the age of the bedrock. |
| Workings or exploration | According to Jansons and others (1984), a 60 ft adit and open pits were present. The U.S. Bureau of Mines (Jansons and others, 1984) reported five chip samples contained from 20 ppm to 3 percent Cu and 2.6 to 46 ppm Ag. Four grab samples contained from 195 ppm to 0.94 percent Cu, 2.7 to 8.8 ppm Ag, and 9 ppm to 0.18 percent Ni. The potential for mineral development is low. |

| Reserve estimates | Hoekzema (1984) reported that the inferred reserves are 33,500 tons at 0.22 percent Cu and 21.2 ppm Ag. The potential for mineral development is low. |
