Black Pine Project

The Black Pine Project is a copper and cobalt mine located in Lemhi county, Idaho at an elevation of 7,500 feet.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Exploration): THE DMEA HAS DONE A GOOD DEAL OF DEVELOPMENT WORK AT THIS PROPERTY. THE PROGRAM RESULTED IN THE DISCOVERY OF 29,800 ST OF INDICATED ORE WITH AN AVERAGE GRADE OF 6.1% COPPER AND 2,200 ST OF INFERRED ORE WITH AN AVERAGE GRADE OF 5.4% CU. IN 1994 EXPLORATION 5 OF 6 ZONES WERE TESTED; PROGRAM DISCOVER- ED 9.2 FT OF 1.249% CO AND 0.409 OZ AU/ST (14.02 G/MT).

Comment (Economic Factors): A NEARLY COMPLETE MILL FACILITY IS STILL LOCATED ON THE PROPERTY.

Comment (Geology): ORE IS BOTH CU-CO OXIDES AND CO-CU-AU SULFIDES.

Comment (Economic Factors): OLD UNDERGROUND MINE WORKING WILL BE OPENED UP, MAPPED, SAMPLED TO CONFIRM RESERVES AND DEFINE PRESENCE OF HIGH GRADE COBALT.

Comment (Economic Factors): MINE WAS LAST MINED IN THE 1960; THEIR ARE OVER 4500 FT OF UNDERGROUND WORKINGS.

Comment (Deposit): 2 VEINS

Comment (Development): FLOTATION MILL IN 1956 ; ECON.COM: HEAVY GROUND ALONG MINERALIZED SHEAR ZONES REQUIRES MUCH TIMBERING (SIX MILLSITES BEING VALIDLY USED IN CONJUNCTION WITH THESE CLAIMS - BLACK PINE, CROSS CUT COPPER, NO. 1 FRACTION, BIG COBALT, BIG COBALT NOS 1 AND 2)

Comment (Geology): BEDDING TRENDS NW AND DIPS NE ; GEOL.DESC: 2 VEIN ZONES:(A)CHALCOPYRITE-PYRITE ON 40-90 FT. NORTHWEST-STRIKING, NORTHEAST DIPPING SHEAR ZONE(NO COBALT);(B)QUARTZ VEIN CARRYING COBALTIAN ARSENOPYRITE 140 FT. NORTHEAST OF (A) ZONE; COUNTRY ROCK HIGHLY FOLDED.

Comment (Location): NEAR HEADWATERS OF N. BRANCH OF COPPER CREEK

Comment (Production): ITEM 1 WAS PROBABLY A TEST SHIPMENT (This statement doesn't make sense. No production was given in old MRDS record, or at least was not copied to new MRDS record.)

Comment (Workings): 5 ADITS TRENDING NW WITH DRIFTS TO SW; NUMEROUS TRENCHES
