Subject category Comment text
Deposit DOM. REF. INCLUDE THIS WITH PLACER COUNTY MINES, BUT DESCRIPTION OF LOCATION IN 15TH REPT. DOM, SAYING LOC. WEST OF GREENHORN CREEK WOULD PLACE LOCATION IN NEVADA COUNTY; HOWEVER, THIS REFERENCE PROBABLY DERIVED INFORMATION FROM USGS FOLIO 66, P. 7, AND EC. GEOL. SHEET WHICH SHOW A COPPER PROSPECT EAST OF THE GREENHORN CREEK, SOUTH OF POORMAN CREEK, AND ON OR SLIGHTLY WEST OF THE ROAD. THE UNIDENTIFIED SHAFT SHOWN IN NE1/4 NW1/4 OF SEC. 14 ON TOPO MAP MAY BE THIS PROSPECT?
