Land Status

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property.

Comments

Comment (Location): ON EAST SIDE OF STANK HILL

Comment (Production): LATER PRODUCTION WAS NOT RECORDED SEPARATELY FROM OTHER DISTRICT MINES

Comment (Geology): IN LOWER LEVELS OF STANK MINE THE PRE-MINERAL FAULT PLANE APPEARS TO HAVE ROTATED BY THE POST-MINERAL FAULT SYSTEM.

Comment (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

Comment (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

Comment (Workings): 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.

Comment (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.

Comment (Deposit): ANDESITE DIKE, AS WELL AS BOTH PRE-MINERAL AND POST--MINERAL FAULTS.
