Workings at the site

  • Type of workings Unknown
    Overall depth 27.4M

Comments on the workings information

  • A SINGLE VERTICAL SHAFT IS THE ONLY WORKING REPORTED. THE SHAFT WAS FLOODED, WITH A SMALL COVERED DUMP WHEN THE SITE WAS VISITED IN 1974.

Comments on development

  • THIS AND THE OTHER 3 NEW CANTON MINES WERE ORIGINALLY WORKED FROM THE 1770'S TO AROUND 1840 FOR THEIR LIMONITE GOSSAN WHICH OUTCROPS ABOVE THE SULFIDES. THE MOST INTENSIVE MINING OCCURRED IN THE 1830'S, WHEN A CHARCOAL FURNACE, KNOWN AS THE BEAR GARDEN OR DEAN FURNACE, WAS BUILT ABOUT HALF A MILE SOUTH OF NEW CANTON. THE GOSSAN WAS SMELTED AT THIS FURNACE UNTIL IT WAS ABANDONED IN 1840. IN 1910 THE MINE WAS OPENED BY AN 80 TO 90 FT (24 TO 27 M) SHAFT IN SEARCH OF A PYRITE DEPOSIT. IN 1911 THE SHAFT WAS PUMPED OUT AND PREPARATIONS WERE BEING MADE TO DEEPEN IT, BUT NO FURTHER INFORMATION IS AVAILABLE. IN 1956 R.F. BEERS, INC., DIAMOND DRILLED THE MINE AREA UNDER CONTRACT WITH THE DEFENSE MINERALS EXPLORATION ADMINISTRATION.

General comments

Subject category Comment text
Deposit PYRITE OCCURS IN THE SHAFT AT ABOUT 9.1 M DEPTH, WHERE THE WATER LEVEL IS ENCOUNTERED. IT IS SOMEWHAT CUPRIFEROUS AND IS THE CHIEF ORE MINERAL. AT THE 16.8 M DEPTH, CHALCOPYRITE AND BORNITE ACCOMPANY THE PYRITE. THE SULFIDES ARE NOT PLENTIFUL, AND APPEAR CONFINED TO PLANAR AND LENTICULAR ZONES WHICH PARALLEL THE SCHISTOSITY, AND OCCUR IN A ZONE 1.2-1.5 M THICK, AS MEASURED NORMAL TO THE SCHISTOSITY. PYRITE IS THE ONLY ORE MINERAL AT THE BOTTOM OF THE SHAFT AT DEPTH 27.4 M. THE STRIKE REFERS TO THE FOLIATION OF THE SCHIST, WHICH HAS A NEARLY VERTICAL NORTHWEST-WARD DIP (TABER, 1913).
Deposit THIS MINE IS ONE OF A GROUP OF 4 MINES AND PROSPECTS THAT ARE COLLECTIVELY NAMED THE NEW CANTON MINES; JOHNSON MINE, HUDGINS PROSPECT, AND MCKENNA PROSPECT. ALL 4 LIE ON THE SAME NE-SW STRIKE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
