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 LATERITES WERE TRANSPORTED AND DEPOSITED BENEATH OR AS BASAL BEDS OF THE EOCENE SWAUK FORMATION. LAMEY(1950, P.1) TENTATIVELY INTERPRETS THE CONGLOMERATIC IRON BEDS AS LANDSLIDE DEBRIS OR MUDFLOW DEPOSITS
Comment (Deposit): IRON DEPOSITS OF THE BLEWETT AREA WERE EVALUATED IN THE 1940'S BY THE WASHINGTON DIVISION OF GEOLOGY. THIS WAS FOLLOWED BY EXTENSIVE DRILLING BY THE U. S. BUREAU OF MINES (10 HOLES, 2395 FT.) AND METALLURGICAL TESTING. (SEE REFERENCES FOR SPECIFIC REPORTS.) THIS EVALUATION SHOWED RESERVES OF 46,000 TONS AT A GRADE OF 0.88% NI, 2.5% CR2 O3, 32% FE, AND 8,000,000 TONS AT A GRADE OF 0.39% NI, 0.85% CR2 O3, AND 11.53% FE (HUNTTING, 1956, P. 194).
Comment (Location): ON A PROMINENT RIDGE NORTH OF SHASER CREEK AT ITS JUNCTION WITH PESHASTIN CREEK
Comment (Development): ECON.COM: THE BLEWETT IRON DEPOSIT HAS NOT PRODUCED BUT HAS BEEN EXTENSIVELY EVALUATED AS AN IRON RESOURCE (HUNTTING, 1956, P. 194).
