Economic information

Controls for ore emplacement

  • Mineralization Is Contained In Several Undulating Shear Zones In Hydrothermally Altered Alaskite, Aplite, And Monzonite (Purdy, 1954, P. 34-44). Shear Zones Do Not Appear To Continue For More Than 30 Feet. Sericite, Kaolinite, And Disseminated Ore Minerals Are Present In The Shear Zones. Ore Minerals Are Localized In Small Ore Shoots.

Comments on the geologic information

  • THE DEPOSIT IS WITHIN THE ALKALIC COMPLEX OF BIMETALLIC MOUNTAIN, WHICH IS OF CRETACEOUS OR TERTIARY AGE. THE MONZONITE, WHICH IS BRECCIATED AND LOCALLY INCLUDES SKONKINITE, IS INTRUDED BY HYDROTHERMALLY ALTERED, FINE-GRAINED, ALASKITE DIKES. THE ROCKS INTRUDE METASEDIMENTARY ROCKS OF THE SPECTACLE FORMATION OF THE PERMIAN ANARCHIST GROUP, WHICH ARE LOCALLY HORNFELSED (STOFFEL, 1990).

Deposit DEVELOPMENT CONSISTS OF SEVERAL SHAFTS AND TWO ADITS. A TOTAL OF 2200 FEET OF LINEAR TRENCHING WAS DONE BY THE U.S. BUREAU OF MINES (USBM) IN 1945 TO DETERMINE THE EXTENT OF MINERALIZATION; NO SIGNIFICANT MINERALIZATION WAS FOUND. ASSAYS OF SAMPLES FROM THE ADIT BY THE USBM RANGED FROM 2.20 TO 3.87% MO AND 0.03 TO 0.32% CU AND SHOWED TRACES OF AU AND AG. SAMPLES TAKEN FROM THE TRENCH AVERAGED 0.32% CU; TRACE AMOUNTS OF AU AND AG WERE FOUND IN SOME SAMPLES. SAMPLING SUGGESTS THAT THE BETTER COPPER VALUES ARE FOUND IN SAMPLES FROM NEAR THE SURFACE, WHEREAS THE HIGHER MOLYBDENUM VALUES ARE FROM SAMPLES COLLECTED AT DEEPER LEVELS IN THE MINERALIZED SYSTEM (MOEN, 1980, P. 57). ; INFO.SRC : 1 PUB LIT
