Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Geology): THE NORTHWEST-TRENDING AENEAS CREEK PLUTON IS 1 MILE WIDE AND 3 MILES LONG. IT CONSISTS OF A CENTRAL PHASE AND A BORDER PHASE THAT IS IN CONTACT WITH PERMIAN ANARCHIST GROUP METASEDIMENTARY ROCKS. THE DEPOSIT IS IN THE CENTRAL PHASE OF THE PLUTON. THE PLUTON CONSISTS OF MEDIUM CRYSTALLINE BIOTITE-HORNBLENDE QUARTZ MONZONITE AND GRANODIORITE. THE PLUTON HAS YIELDED K-AR BIOTITE AGES OF 92.7 +- 6.6 M.Y. AND 98.3 +- 3.5 M.Y. A CONCORDANT K-AR HORNBLENDE AGE WAS 92.3 +- 4.3 M.Y.
Comment (Production): THREE THOUSAND TONS OF HAND-SORTED ORE, WHICH AVERAGED 1.0% MOS2, WAS SHIPPED IN 1939 (HUNTTING, 1956, P. 271). MATERIAL FROM DUMPS OF THE NO. 1 AND NO. 2 ADITS WAS SHIPPED AFTER 1944.
Comment (Deposit): THE PROPERTY CONSISTS OF UNPATENTED MINING CLAIMS AND IS OWNED (1990) BY WILBUR G. HALLAUER OF OROVILLE.
Comment (Deposit): IN 1928 THE PROPERTY WAS EXPLORED BY MOLYBDENUM CORPORATION OF AMERICA AND IN 1935 AND 1936 BY TITANIUM ALLOY MANUFACTURING CO. CARL LUNDSTROM MINED THE PROPERTY IN 1939. IN TOTAL THERE ARE 2700 FEET OF UNDERGROUND WORKINGS. IN 1959 SIX SHORT DIAMOND DRILL HOLES WERE COMPLETED. FROM 1966 TO 1967 CAMBRI MINING AND DEVELOPMENT CO. LTD. LEASED THE PROPERTY AND DRILLED SIX 200-FT HOLES.
