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): THE MINE IS LOCATED NEAR THE S END OF A NARROW, NS TRENDING ULTRAMAFIC MASS, THAT IS EXPOSED FOR ALMOST 6 MILES.
Comment (Production): WILLIAMSON BROTHERS AND COLE REPORTED PRODUCTION OF 402 LONG TONS OF ORE IN 1916, 384 TONS IN 1917, 230 TONS IN 1918 AND 359 TONS IN 1919, TOTAL OF 1,375 LONG TONS; OF THIS TOTAL 1,250 TONS APPROX. CAME FROM THIS LOCATION, REMAINDER FROM OTHER DEPOSITS OPERATED BY THE PARTNERSHIP. 5 TONS WERE MINED FROM A STRINGER AND A POD IN 1943.
Comment (Deposit): DEPOSIT CONSISTS OF A NUMBER OF PODS OF VARYING SIZES AND ORIENTATIONS. THE MINERALIZED ZONE HAS THE ABOVE STRIKE AND DIP.
Comment (Workings): WORKINGS CONSISTED OF TWO OPEN CUTS UNDERNEATH WHICHSEVERAL DRIFTS AND STOPES HAD BEEN CUT.
Comment (Location): LOCATED AT THE HEAD OF A NW FACING GULLY.
Comment (Deposit): COMPRISES CLAIMS AGGREGATING 150 ACRES (MAY INCLUDE THE RAPID FIRE IN SEC. 12). ORE LARGELY OF MASSIVE CHROMITE MUCH OF WHICH WAS SHATTERED AND BROKEN, THE PIECES BEING COATED WITH TALC AND KAMMERERITE AND A LITTLE UVAROVITE. AN UNEXPLORED BLOCK OF GROUND AT LEAST 100 FT. LONG BETWEEN THE TWO PRINCIPAL ORE BODIES COULD EASILY CONTAIN ONE OR MORE ORE BODIES OF APPRECIABLE SIZE.
