GOLDEN WEDGE MINE (gold) GALIOE DISTRICT JOSEPHINE COUNTY The Golden Wedge mine is about 4 miles northwest of Galice on Bailey gulch. It is said to have been discovered by Mr. Hutchins in 1893. About 1908 the mine passed into the control of the Gold Road Mining & Milling Company, which was reorganized about 1911 as the Bailey Gulch Mining & Milling Company. Diller suggests that the total production of this mine may have reached $50,000 and that future production may result if the Oriole fault is found. The main ore body is opened by about 1200 feet of underground workings, reaching a depth of about 500 feet on the incline. The lode strikes about N 20 E. and dips 50-60 E. The ore body pitches southward at an angle of about 20. According to Diller, the "quartz veins and lenses in the sheared greenstone are irregular, as if folded, and many of the quartz lenses or kidneys that have a covering of graphitic material with grains of pyrite are said to average $10 to $20 a ton in gold. Considerable ore has been stoped out of a belt ranging from 16 inches to 5 feet. The graphitic material interferes with handling the ore." The country rock here is a greenstone with intrusions of dacite, containing abundant dark green hornblende with fine granular quartz, sericitized plagioclase, and unusually abundant granular titanite. An adit near the mill on Bailey gulch is (1913) being extended. It exposes a thick fault gouge, which suggests an important fault. The gouge is grayish blue when dry and nearly black and soft when wet. It consists chiefly of quartz, siderite, pyrite and sericite, and is therefore more
