Comments
Comment (Development): ECON.COM: PRODUCED $40,000 WORTH OF ORE PRIOR TO 1903; ORE WAS SHIPPED FROM THE DUMP IN 1935 (HUNTTING, 1956, P. 295).
Comment (Deposit): THE ZALLA M IS IN FLOWS AND BRECCIAS OF THE EOCENE KLONDIKE MOUNTAIN FORMATION. THE ROCKS APPEAR TO BE RHYOLITIC IN COMPOSITION, BUT ON CLOSE EXAMINATION, OUTLINES OF WHAT APPEAR TO BE PYROXENE PHENOCRYSTS ARE FOUND. THIS SUGGESTS THE ROCKS ARE PROBABLY ALTERED ANDESITE (STOFFEL, 1990, GEOL. MAP, P. 11; PEARSON, 1967, GEOL. MAP). ; INFO.SRC : 1 PUB LIT
Comment (Location): A FEW HUNDRED YARDS EAST OF THE FERRY-OKANOGAN COUNTY BOUNDARY LINE
