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
