ORO RICA MINE (PINON BLANCO)

This property consists of the Pinon Blanco, North Pinon Blanco, Old Judge, South Judge, Little Judge and millsite, patented claims, having an area of 95 acres, and the Star lode claim and Stephen placer unpatented claims, owned by the Oro Rica Mines Company, care of A. E. Tower, Metropolitan Club, New York.  The mine is in Sec. 19, 20, and 29, T. 2 S., R. 16 E., about three miles north of Coulterville, near the northern  boundary of the county.  There are two contact veins, varying from three to six feet in width, between a slate footwall and diorite hanging wall  The strike is N. 20 degrees W. and dip 65 degrees NE.  The outcrop of the vein and workings on the top of Pinon Blanco Ridge form a conspicuous landmark.  The property is developed by a tunnel over 200 feet long, with 900 feet driven on the vein.  It is equipped with a 20-stamp mill, but litigation over ownership has resulted in the mine being idle for the past ten years.
