| Deposit | PROSPECT LIES BELOW TOP OF JUNCTION CREEK SANDSTONE, WHICH LOCALLY TRENDS N 75 W, 18 SW. SEVERAL MINOR SLIPS CONTAINING LITTLE GOUGE TREND N 50 TO 70 W, 40 TO 45 SW. ALTHOUGH PROSPECT HAS PRODUCED NO ORE, IT ILLUSTRATES UNUSUAL MODE OF AU OCCURRENCE IN DISTRICT. ROCK IS NOT VISIBLY MINERALIZED BUT SOFT, FRIABLE SANDSTONE YIELDS FREE AU WHEN PANNED. |
| Deposit | Changed district name from California (La Plata) to La Plata (California) to eliminate confusion with other California districts. |
| Deposit | From 10191337 (record deleted): "Fine gold disseminated in Junction Ck. Sandstone. BP Minerals drilled this area in 1988, and Wes Potts operated the mine intermittently in 1990." This same record includes Twin Canyon claim as a previous name. Not clear if Twin Canyon is part of Charlene or a separate site. |
| Deposit | From 10239262 (record deleted): "Fine gold disseminated in Junction Ck. Sandstone. Area was drilled in 1988. Small, unrecorded production in 1990. |
| Deposit | Twin Canyon claim, Twin Canyons 1-8 claims, and Charlene tunnel are all part of this site. Add 10191227 and 10090680 to this record and delete those duplicates. |
| Deposit | Twin Canyon and Twin Canyons 1-8 list Silver as an additional commodity. If present, it is minor or trace. |
