Xtra Energy Corp. announced the successfully completed 20 acre expansion to gain full ownership rights of the historical antimony producing Drumm Mine. The Drumm Mine is directly adjacent and west of American Antimony #59 lode claim that holds Far South Marguerite Prospect.

This brings total ownership rights to fourteen historically documented antimony mines over 1425 acres in the Bernice Mining District of Churchill County, Nevada. As described in LAWRENCE, E.F., 1963, ANTIMONY DEPOSITS of NEVADA; NBMG BULL.61; "The Drumm mine is on the west side of a southeast-trending side canyon, which meets Bernice Canyon 3.8 miles from the mouth of the canyon, 500 feet above the canyon floor. The mine is developed by a 22-foot adit, 40-foot crosscut, and a 95-foot inclined winze.

In 1940, 28 tons of ore averaging 52% antimony were produced. During 1941 and 1942, 57 tons of ore containing 48.2% antimony were produced. The country rock is brown shale dipping 80deg E. A dense, brown sill crops out below the portal of the adit.

It is highly sericitized, but apparently was composed of at least 10% feldspar phenocrysts in a groundmass of feldspar and quartz. A 6-inch quartz vein containing numerous pods of stibnite up to 10 by 24 inches in size is exposed in the adit. One limb of the vein strikes N. 25deg E. and dips 15deg E.; the other limb dips 35deg to the west.

The winze was sunk in the westward-dipping limb of the vein. A 6-inch wide sample of the easterly dipping limb assayed a trace of gold and 0.04 ounce of silver per ton, and 16.37% antimony. The width of the vein varies greatly in the winze, but at the bottom a brecciated zone up to 48 inches wide has been recemented by quartz containing pods and veinlets of stibnite.

In both the adit and crosscut, small pods of stibnite are disseminated through the wall rock. The stibnite has been oxidized slightly to yellow antimony oxides.
