Mine Info

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: Private
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.

Comments

Comment (Deposit): THIS DEPOSIT WAS EVALUATED AT EFOC. A COLUMBITE-TANTALITE ENRICHED ZONE OCCURS SUBJACENT TO THE SPODUMENE-QUARTZ ORE BODY. THIS ZONE IS LOW GRADE AND NEEDS FURTHER EXPLORATION TO DEVELOP A RESOURCE TONNAGE.

Comment (Names): OTHER NAMES:TANTALUM HILL PEGMATITE, GIANT PEGMATITE.

Comment (Workings): WORKING SEASON ASSUMED TO BE FOR 9 MONTHS; MINE SHUT DOWN DURING WINTER MONTHS.

Comment (Geology): THE EXTENT OF THE PEGMATITE DOWN-DIP IS 49 TO 73 METERS.

Comment (Ownership): TOTAL LAND HOLDING IS ESTIMATED TO BE 4 HECTARES.
