Comments on the workings information

  • IN 1974, TEN CAVED PITS, COVERED DUMPS, OLD BUILDING CONTAINING AN OLD JIG AND CONCRETE FOUNDATIONS SEEN. FROM 1836 TO 1838 THE MINE WAS DEVELOPED BY TWO INCLINED SHAFTS, 9.5 AND 15 M (31 AND 50 FT) DEEP, CONNECTED AT THE 9-M (30-FT) LEVEL BY A DRIFT 21 M (70 FT) LONG. IN 1891 THE MANNING SHAFT, OR NO. 1 SHAFT, WAS SUNK TO A DEPTH OF 14.6 M (48 FT)? IN 1893 THE SHAFT WAS FURTHER DEEPENED TO 22 M (72 FT), AND THE OLD STEVENS SHAFT WAS SUNK ABOUT 21 M (70 FT) SOUTHWEST OF NO. 1 AND THE TWO SHAFTS WERE CONNECTED BY A DRIFT ON THE 22-M LEVEL. FROM 1902 TO 1904 THE NO. 1 SHAFT WAS DEEPENED TO 36 M (118 FT)? AT THE 19-M LEVEL A SET OF 3 DRIFTS, ONE DIRECTLY OVER THE OTHER, IN LIEU OF STOPING, WAS RUN FOR A TOTAL DISTANCE OF 87 M (285 FT) ALONG THE VEIN. A SECOND OLD SHAFT, WHICH MAY HAVE BEEN THE OLD STEVENS SHAFT, WAS SUNS TO 40 M ON THE INCLINE, AND DRIFTS WERE RUN 18 M (60 FT) IN EACH DIRECTION ON THE VEIN AT A DEPTH OF 33.5 M (110 FT)? THE LAST 6 M (20 FT) OF EACH DRIFT WAS STOPED TO A
  • HEIGHT OF 6 M (20 FT) ABOVE THE FLOOR OF THE DRIFT. IN 1931 A DRAINAGE SHAFT 21 M (70 FT) IN BACK OF THE VEIN WAS SUNK ON A 45 DEG INCLINE TO A DEPTH OF 40 M (132 FT) SOLELY FOR DRAINING THE UPPER PORTIONS OF THE OLD WORKINGS TO PERMIT THEIR RETIMBERING. THE NO. 1 SHAFT WAS RECONDITIONED AND SUNK TO A DEPTH OF 46 M (150 FT) ON THE INCLINE. AT THE 46-M LEVEL DRIFTS WERE RUN 32 M (105 FT) NORTHEAST AND 53 M (173 FT) SOUTHWEST. NO. 2 SHAFT,63 M (208 FT) SOUTHWEST OF NO. 1 AT THE SURFACE ALONG THE STRIKE OF THE VEIN, WAS SUNK TO A DEPTH OF 32 M (106 FT) ON THE INCLINE. DURING 1936, NO. 2 SHAFT WAS SUNK TO A DEPTH OF 70 M (228 FT) ON THE INCLINE, PASSING THROUGH SEVERAL OLD DRIFTS. IN NO. 2 SHAFT DRIFTS WERE RUN AT THE 27-M (90 FT) LEVEL 21 M (69 FT) NORTHEAST AND 17 M (55 FT) SOUTHWEST. AT THE 38-M (125-FT) LEVEL A DRIFT WAS RUN 6 M (20 FT) NORTHEAST. AT THE 70-M LEVEL DRIFTS WERE EXTENDED ABOUT 4.6 M (15 FT) IN EACH DIRECTION. IN LATE 1984, AN ATTEMPT WAS MADE TO REOPEN THE OLD NO.
  • 2 INCLINED SHAFT. THE RAILS FOR THE MINE CARS WERE UNCOVERED AS WELL AS AN ADJACENT INCLINED SHAFT. TIMBERS WERE ALSO OBSERVED IN THE SHAFT BEFORE IT CAVED IN AGAIN.

Comments on development

  • DEPOSIT WAS DISCOVERED BY JOHN MOSS IN 1835. THE RICHMOND MINING CO. OPERATED THE MINE FROM 1836 TO 1838. IT WAS REOPENED IN 1891 BY G.H. MANNING WHO SANK THE MANNING SHAFT. A 3-STAMP MILL WAS ERECTED TO AID IN TESTING THE ORE. IN 1893 THE MINE WAS LEASED BY A MR. STEVENS, WHO SANK THE OLD STEVENS SHAFT. FROM 1902 TO 1904 THE TELLURIC GOLD MINING CO. OPERATED THE MINE, ADDING ANOTHER BATTERY OF 3 STAMPS TO THE MILL. IN 1931 J.C. WILLIAMS, SR., AND OTHERS, OPERATED THE MINE AND ERECTED A 3-STAMP MILL FOR TESTING THE ORE. WORK LASTED UNTIL 1933 WHEN LACK OF CAPITAL FORCED CLOSURE. THE MOSS MINING CO. OPERATED THE MINE IN 1936, ERECTING A MILL THAT UTITIZED A JAW CRUSHER, BALL MILL, CLASSIFIER, DENVER MINERAL JIG, CORDUROY BLANKETS, FLOTATION UNIT, CONCENTRATE TANK, AMALGAM DRUM, AND AMALGAMATING PLATES. THE MINE HAS NOT BEEN OPERATED SINCE 1936. NO AVAILABLE ORE EXISTS ABOVE 46 M LEVEL BETWEEN NOS. 1 AND 2 SHAFTS EXCEPT IN PILLARS AND BENCHES.
