The Hall Mountain is a thorium mine located in Boundary county, Idaho at an elevation of 3,399 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

Land Status
Land ownership: BLM Administrative Area
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 (Geology): Nelson Batholith May Be Distant Magma Source For Thorium Bearing Fluids
Comment (Reserve-Resource): Yttrium
Comment (Deposit): Property Is Made Up Of Four Individual Deposits, All Located On The West Slope Of Hall Mountain. Included Are The Golden Sceptre, Wawa, Old Outcrop And Pyrite Zone. The Tmu Prospect Was Not Included In Evaluation. Minor Uranium Is Noted In Thorium Area. Also Located In Section 13.
Comment (Reserve-Resource): The Group Consists Of Golden Sceptre, Wawa, Old Outcrop, Pyrite Zone, And Tmu. Ore Mined Ug And Op From 1939 To 1949. Second Owner Is Hall Mountain Thorite (Bruce Berringer)
Comment (Geology): Thorium Content Varies From Trace To Over 40 Percent Copper, Lead, Silver And Gold Values Were Noted In A Company Report Now In U.S. Bureau Of Mines Wfoc Files. (Reliability Unknown)
Comment (Production): Significant Development Has Occurred At The Golden Sceptre Mine For Copper And Silver; However, No Production Has Been Recorded Exploratory Mine Work At The Golden Sceptre Mine Exceeds 1500 Meters But Followed A Prospective Gold/Quartz Vein Rather Then The Thorium Rich Quartz/Calcite Vein.
