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 (Reserve-Resource): NATURE OF ORE BODY AND LOCATION PRECLUDES POSSIBILITY OF SIZEABLE POTENTIAL RESOURCES. SOME LOW-GRADE ROCK MAY BE FOUND ON PERIPHYRY. REED STATES THAT INFERRED RESERVES MAY AMOUNT TO MORE THAN 300,000 ST. AS OF 1947. 1948-52 PRODUCTION WAS ABOUT 160,000 ST.
Comment (Development): BEAR CREEK MINING CO. PURCHASED MINE IN 1962 FROM MCLAREN GOLD MINES AND CONDUCTED DIAMOND DRILLING AND OTHER EXPLORATION THROUGH 1967
Comment (Workings): DEPOSIT EXPOSED BY OPEN-CUTS FOR ABOUT 500 FT. IN 1948. ORE TREATED BY 185 TON FLOATION & GRAVITY MILL.
Comment (Geology): ORE BODY IS IN A XENOLITH OF GROS VENTRE BEDS ENCLOSED BY MONZONITE PORPHYRY. IN GENERAL MINERALIZATION IN DISTRICT APPEARS TO BE CONCENTRATED ALONG CONTACT OF INTRUSIVE BRECCIA AND CARBONATE ROCKS.
