Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Reserve-Resource): ADDITIONAL RESERVES AND RESOURCES HAVE BEEN LOCATED IN LATE 1970'S, BUT TONNAGE AND GRADE ARE UNPUBLISHED
Comment (Commodity): LIST OF MINERALS IS PARTIAL
Comment (Location): LOCATION GIVEN IS FOR ROSS-ADAMS MINE, OTHER LOCATIONS ARE TO THE EAST LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Production): ORE WAS AT LEAST AS RICH IN THORIUM, BUT IT WAS NOT RECOVERED
Comment (Development): EXPLORATION HAS CONTINUED AT LEAST THROUGH 1982, BUT URANIUM PRICES ARE TOO LOW FOR MINING
Comment (Deposit): VEINLETS AND DISSEMINATIONS OF ORE ARE IN FUSIFORM SHAPED ZONE WITHIN PERALKALINE INTRUSION. ALSO, SEVERAL INTERESTING PROSPECTS TO THE EAST, (I+L, ETC.) ARE IN VEINS.
Comment (Workings): MINING FROM AN OPEN PIT AT FIRST. UNDERGROUND WORKINGS MAY HAVE BEEN DEVELOPED LATER
