Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (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.
Comment (Workings): ONE TUNNEL HEADING GENERALLY N 15 E
Comment (Location): (LAND STATUS AND ADMINISTRATIVE AREA LOCATIONS CALCULATED USING GIS OVERLAY ANALYSIS FOR SAN JUAN N. F.). CLAIM LIES IN TWIN CANYON BASIN SOUTH OF EAST MANCOS RIVER AND NORTH OF CAVINESS MOUNTAIN, 4.95 MILES SW OF LA PLATA TOWNSITE (UNSURVEYED SECTION). ; INFO FROM LAND.ST :1974
Comment (Names): Neubert and others, 1992 (MLA 2-92) p. 87 clears up the name mystery: "The Charlene Mine (recently renamed the Twin Canyon)..." However, the name on the maps and in the literature is Charlene so that is the name used in this database as the current name.
Comment (Deposit): Changed district name from California (La Plata) to La Plata (California) to eliminate confusion with other California districts.
Comment (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.
Comment (Deposit): Twin Canyon and Twin Canyons 1-8 list Silver as an additional commodity. If present, it is minor or trace.
Comment (Production): Record 10191337 (deleted) suggests that the mine may have been operational in 1990, 41 years after PP-219 was published in 1949. This would elevate the Development Status to Past Producer. Record 10239262 (record deleted) seems to verify this: "Fine gold disseminated in Junction Ck. Sandstone. Area was drilled in 1988. Small, unrecorded production in 1990.
Comment (Deposit): From 10239262 (record deleted): "Fine gold disseminated in Junction Ck. Sandstone. Area was drilled in 1988. Small, unrecorded production in 1990.
Comment (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.
