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.

Materials
Ore: Malachite
Comments
Comment (Development): WORKED IN EARLY 1900'S, WITH OLD TAILINGS FROM THIS ERA IN A SMALL WASH EAST OF THE SHAFT. NO ACTIVITY IN 1984.
Comment (Workings): SEVERAL PITS AND SHALLOW SHAFTS, ONE OF WHICH IS SHOWN ON THE TOPO MAP. BULLDOZING IN THE LAST FEW YEARS AND A VER-Y SMALL-SCALE ATTEMPT TO BATCH LEACH SOME ORE, PROBABLY FOR PR-ECIOUS METALS.
Comment (Deposit): MALACHITE AND AZURITE ALONG FAULTS THAT STRIKE NW AND N-S IN CHERT AND GREENSTONE ASSOCIATED WITH QUARTZ MONZONITE PORPHYRY INTRUSIVES ; INFO.SRC : 1 PUB LIT; 3 FIELD OBSERV
Comment (Deposit): OXIDE COPPER MINERALS AND IRON AND MN OXIDES OCCUR ALONG A PROBABLE SHEAR ZONE IN GREENSTONE AND CHERT OF THE PUMP-ERNICKEL OR HAVALLAH FMS. SIMILAR MINERALIZATION IS PRESENT IN- A POSSIBLE LOW-ANGLE NORTH-TRENDING FAULT ZONE IN A SMALL PIT- SW OF THE MAIN SHAFT. LITTLE OBVIOUS HYDROTHERMAL ALTERATION;- THE GREENSTONE MAY BE LOCALLY ARGILLIZED.
