Comments on development

  • ORIGINALLY PROSPECTED FOR SILVER AND COPPER (EARLY 1900'). OWNED BY A MR. SAUNDERS OF WINNEMUCCA, THE PROPERTY WAS LEASED TO HAROLD'S CLUB MINING CO OF RENO IN 1943 AND 19-44, AND TO MR. DON BERGNER IN 1945. ABOUT 1530 TONS ORE AVERAG-ING 0.95 % WO3 WERE SHIPPED TO THE METALS RESERVE CO FOR STOCK-PILING IN 1943-1944. THE PROPERTY, OWNED BY THE VALLEY VIEW MI-NING CO. AND BY R. B. SPITZER WAS AGAIN ACTIVE 1951-1956 DURIN-G WHICH TIME 72000 TONS ORE (0.55 % WO3) WERE MINED AND SHIPPE-D TO GETCHELL MILL.

General comments

Subject category Comment text
Deposit MINE IS ON THE EAST SIDE OF THE GRANODIORITE STOCK ALONG THE NEARLY-CONCORDANT, EAST-DIPPING CONTACT BETWEEN GRANO-DIORITE AND LIMESTONE. THE EAST WALL OF THE TACTITE LAYER EXPO-SED IN THE NORTH ADIT, IS GOUGE AND SHEARED ROCK OF THE LARGE -GETCHELL FAULT ZONE ALONG THE EAST SIDE OF THE RANGE. THE TACT-ITE IS TIGHTLY SEALED AGAINST THE GRANODIORITE, AND THE TWO RO-CK TYPES SERVE LOCALLY AS A FOOTWALL FOR THE WIDE FAULT ZONE. -ELSEWHERE THE FAULT MAY CUT THROUGH PROJECTIONS OF TACTITE AND- GRANODIORITE, AND IT PROBABLY CUTS ACROSS GENTLY DIPPING PORT-IONS OF THE CONTACT ZONE AT DEPTH, THUS LIMITING THE DOWNWARD -EXTENT OF PART OF THE ORE ZONE.
Deposit AREA WAS ORIGINALLY PROSPECTED FOR SILVER AND COPPER. MINED FROM 1943-1944 AND 1951-1955 IN SURFACE OPERATIONS. NORTH OF THE MINE A FEW HUNDRED FEET IS A THIN (3-10 FT WIDE) DISCONTINUOUS TACTITE BODY WHICH OUTCROPS FOR 200-250 FT., CONTAINING 0.3 TO 0.4% WO3. IN 1945, WORKINGS CNSISTED OF A 255-FT. ADIT, A 315-FT. ADIT AS WELL AS MANY PITS, TRENCHES AND SHORT ADITS ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
