Comments on development

  • AERIAL AND GROUND MAGNETICS, GRAVITY, SEISMIC, AND IP STUDIES WERE DONE IN 1963 AND 1964. DRILLING BEGAN IN 1965. MARTEL DRILLED 19,887 FT. IN 7 HOLES. A TOTAL OF 27,987 FT. WERE DRILLED IN 11 HOLES BETWEEN 1965 AND 1969. SEISMIC SURVEYS WERE NOT USEFUL IN DELINEATING POTENTIAL ECONOMIC TARGETS. THE LAST KNOWN EXPLORATION WAS IN 1978. AFTER 1978, LEASE NEGOTIATIONS BETWEEN THE COMPANIES AND THE WALKER RIVER TRIBAL COUNCIL BROKE DOWN. ; ECON.COM: ASSAYS FROM 1,760 FT. - 2,286 FT. RAN 46.8% FE, 3.08% S, 0.5% CU, 0.03% P, ADDITIONAL METALLURGICAL TESTING RESULTS IN LAWRENCE, 1967, P. 8. SATKOSKI DESCRIBES "DISSAPPOINTING" ANALYSES (P. 58-59).

Subject category Comment text
Deposit THE IP AND DRILLING "DISCLOSED EXTENSIVE MINERALIZATION AT DEPTHS OF 400 FT. ON THE NORTHWEST END AND OVER 1,000 FT. TO THE SOUTHEAST," (LAWRENCE). DRILL HOLE CA-1 CUT THE PRE-TERTIARY/VOLCANIC CONTACT AT 1,308 FT. SKARN AND HORNFELS WERE FOUND IN ALL MARTEL DRILL HOLES. SKARN WAS ALSO REPORTED ON SURFACE IN SEC. 31 (LAWRENCE). CALCITE-GTZ-PY-CHALCOPYRITE/VEINLETS CUT THE SKARN. POSSIBLY 2 MINERALIZING EVENTS, AN EARLIER FE-MN EVENT, AND LATER CU+PB+ZN, ETC. EVENT.
Deposit THE DEPOSIT WAS INITIALLY IDENTIFIED BY GEOPHYSICAL SURVEYS. 10 MILES OF STRIKE-SLIP FAULTING MAY HAVE SEPARATED THE CALICO AND HOTTENTOT DEPOSITS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
