Magnetic

The Magnetic is a iron, gold, copper, and silver mine located in Okanogan county, Washington at an elevation of 5,000 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.

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.

Comments

Comment (Geology): MAGNETITE BODIES ARE LOCATED IN NORTHWEST-TRENDING CONTACT-METAMORPHIC ZONES IN LIMESTONES OF PERMIAN AGE ADJACENT TO BIOTITE-HORNBLENDE GRANODIORITE OF THE JURASSIC-CRETACEOUS BUCKHORN MOUNTAIN PLUTON (MOEN, 1980, P. 47; STOFFEL, 1990, GEOL. MAP).

Comment (Deposit): DEVELOPMENT WORK CONSISTED OF THREE OPEN PITS, TWO ADITS, AND NUMEROUS OPEN CUTS AND PROSPECT PITS. THE MAIN PIT IS 280 FT LONG AND 65-130 FT WIDE AND HAS A MAXIMUM VERTICAL FACE OF 50 FT (MOEN, 1980, P. 49). THE MAGNETIC MINE IS PART OF THE BUCKHORN MOUNTAIN PROJECT DRILLED BY CROWN RESOURCES CORP. IN 1988-89. OTHER THAN IRON THE ORE BODIES CONTAIN TRACES TO 0.02% CU, TRACES TO 0.15 OZ/TON AU, AND 0.05-0.40 OZ/TON AG (MOEN, 1980, P. 49). BROUGHTON (1943, P. 17) ESTIMATED RESERVES OF 4,826,000 TONS OF IRON ORE AVERAGING 47.3% FE, 1.57% S, 0.03% P, AND 0.03% TI. ; INFO.SRC : 1 PUB LIT

Comment (Production): SMALL SHIPMENTS OF COPPER ORE WERE MADE FROM THE NEUTRAL CLAIM TO A SMELTER IN BRITISH COLUMBIA. A TOTAL OF 80,000 TONS OF MAGNETITE WERE SHIPPED FROM THE NEUTRAL CLAIM BETWEEN 1918 AND 1950 (MOEN, 1980, P. 47).
