Comments on the workings information

  • WORKINGS CONSIST OF AN OPEN PIT.

Comments on development

  • DISCOVERED IN 1904 BY FRANK HORTON. A FEW TONS OF ORE WERE HAULED INITIALLY BUT ORE ZONES WERE SMALL. A 35-FT SHAFT WAS SUNK AND ABANDONED. IN 1927 HORTON'S SON REOPENED A PROSPECT SHAFTAND TOOK OUT $150000 WORTH OF ORE. THE MINE WAS THEN INTERMITTENTLY OPERATED TILL 1934. IN 1934 THE MINE WAS PURCHASED AND WEEPAH NEVADA MINING CO WAS FORMED. AN OPEN PIT MINE WAS DEVELOPED AND WORKED AT 250 TONS/DAY. IT WAS LISTED AS AN ACTIVE OPEN PIT SILVER-GOLD MINE EMPLOYING 10 PERSONS IN 1983. DRILLED BY PACIFIC REALM IN 1984-85; SUNSHINE MINING CO. LEASED IT IN 1986 AND BEGAN MINING IT IN SEPT. 1986, SHIPPING 1000 TPD TO ITS 16 TO 1 MILL, 14 MILES AWAY AT SILVER PEAK
