Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite
Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!

Unpublished data cited is available for viewing by contacting Grayd Resources Inc. in Vancouver, B. C., Canada (www.grayd.com), or Northern Associates Inc. in Fairbanks, Alaska.
Location: The Lo Goat occurrence is at an elevation of about 7,300 feet, 3.5 miles northwest of Mount Kimball and 0.3 mile southwest of the Zygoat occurrence (MH247). It is in the SW1/4SW1/4 section 17, T. 19 S., R. 16 E., Fairbanks Meridian. The location is accurate.
Geology: The 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rocks or at the contact of the metavolcanic rocks with graphitic schist or limestone (R.A. Blakestad and others, unpublished Resource Associates of Alaska Inc. report, 1978; E. Hunter, unpublished data, 1998).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 Lo Goat 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 Lo Goat 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).
