Workings at the site

  • Type of workings Surface/Underground

Comments on the workings information

  • AN INCLINED SHAFT TO THE 700 LEVEL, D WINZE FROM THE 700 TO 1200 LEVEL. IN 1944-45 CROSSCUTS WERE EXTENDED WEST TO THE YELLOW SCHEELITE BED ON THE 300 AND 400 LEVELS.

Comments on development

  • STANK FOUND A HEAVY WHITE MINERAL (SCHEELITE) WHILE PANNING FOR SILVER IN WHAT WAS LATER NAMED STANK CANYON. HE IG-NORED IT AT THAT TIME BUT RECALLED HIS FINDINGS WHEN IN 1917, -TUNGSTEN BECAME A SOUGHT-AFTER WAR MATERIAL. HE AND OTHERS RET-URNED TO THE DISTRICT AND STAKED CLAIMS ON STANK HILL. THESE E-ARLY CLAIMS AND OTHERS TO THE EAST ON SUTTON HILL WERE ACQUIRE-D BY PACIFIC TUNGSTEN COMPANY, WHO MINED IT PRODUCTIVELY UNTIL- CONSOLIDATION IN 1925 BY THE NEVADA MASSACHUSETTS COMPANY, WH- O DEVELOPED AND MINED IT THROUGH A 2-COMPARTMENT INCLINED SHA- FT AND WINZE. OPERATIONS CEASED IN 1958.

Deposit THE STANK MINE IS OPEN TO A VERTICAL DEPTH OF ABOUT 1,200 FT. THROUGH AN INCLINED SHAFT TO 700 LEVEL, A WINZE FROM THE 700 TO 1200 LEVEL. IN 1944-45 COROSSCUTS WERE EXTENDED WEST TO THE YELLOW SCHEELITE BED ON THE 300 AND 400 LEVELS. THE STANK MINE IS ON STANK-HUMBOLDT BELT ALONG WITH THE CODD, YELLOW SCHEELITE, KEYES, GEORGE, SPRINGER, AND HUMBOLDT MINES. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
Deposit IN LOWER LEVELS OF STANK MINE THE PRE-MINERAL FAULT PLANE APPEARS TO HAVE ROTATED BY THE POST-MINERAL FAULT SYSTEM.THE STANK SEGMENT OF THE HUMBOLDT BED IS TRACEABLE BY SURFACE OUTCROPS FROM THE WESTERN MARGIN OF THE SPRINGER STO-CK, AT THE FOOT OF STANK HILL, THROUGH THE SADDLE WEST OF STAN-K HILL, ACROSS STANK CANYON AND UPSLOPE TO THE SOUTH, WHERE IT-IS CUT AND OFFSET BY THE STANK FAULT SOUTH OF THE CODD MINE WO-RKINGS. STANK FAULT DIPS SW, AND THE SOUTHERN EXTENSION OF THE- TACTITE BED THEREFORE MOVES TO THE SOUTH WITH DEPTH IN THE MI-NE. TO THE NORTH, THE NORTHERN BOUNDARY OF THE BED IS FORMED B-Y THE CONTACT WITH THE SPRINGER STOCK. THIS CONTACT ALSO DIPS -TO THE SOUTH GIVING THE STANK TACTITE BODY THE SHAPE OF A PAR-ALLELOGRAM THAT RAKES TO THE SOUTH. ALTHOUGH PARTS OF THE OREB-ODY WERE OF VERY GOOD GRADE, LARGE BLOCKS OF LOW-GRADE, UNALTE-RED LIMESTONE AND MARBLE OCCUR WITHIN THE LIMITS OF THE OREBOD-Y. UNDERGROUND, THE OREBODY IS CUT BY 2 MAJOR GRANODIORITE DIK-ES, AND AN
