Location: The EEK occurrence is at an elevation of about 8,700 feet, 2.1 miles northwest of Mount Kimball and west of the Kimball Glacier. The occurrence is in rugged mountains south of a glacier at the head of the West Fork Robertson River. It is in the SE1/4NW1/4 section 21, T. 19 S., R. 16 E., Fairbanks Meridian. The location is accurate.
Geology: The EEK occurrence is part of a trend of distinctive, generally barren, massive and semimassive pyrite-rich mineralization in the upper portion of the Hayes Glacier belt of rocks. This mineralized trend was traced discontinuously from south of the Tok Glacier to the head of the Gakona Glacier. The massive sulfides occur in pyrite-rich felsic metavolcanic rocks or at the contact of the metavolcanic rocks with graphitic schist or limestone (R.A. Blakestad and others, unpublished Resource Associates of Alaska Inc. report, 1978; E. Hunter, unpublished data, 1998). The EEK occurrence is in rocks that consist mainly of metamorphosed quartz keratophyre and meta-andesite and sparse metadacite and metabasalt. These metavolcanic and subordinate metasedimentary rocks are included in the Hayes Glacier subterrane, which is Devonian and older (Nokleberg and others, 1992).
Workings: The EEK occurrence has only had limited surface examination.
Age: Devonian and older, on the basis of the age of the host rock, which is in the Hayes Glacier subterrane (Nokleberg and others, 1992).
