Mine Info

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 (Deposit): MINERALIZED QUARTZ VEINS 3 IN.-15 FT WIDE. NEW LONDON VEIN: NARROW MINERALIZED QUARTZ VEIN ALONG FOOTWALL OF A NARROW BASIC DIKE (N60E, 55NW); HOMESTAKE VEIN: WIDE MINERALIZED QUARTZ VEIN; HOMESTAKE-LONG ADIT VEIN: 3 FT WIDE QUARTZ VEIN; MINERALITE VEIN: 2-4 FT QUARTZ VEIN; ROOSEVELT VEIN: 2.5-3 FT QUARTZ VEIN WITH PODFS OF SULFIDES IN VEIN WALLS, SCHEELITE IN POCKETS AND STRINGERS; MILWAUKEE VEIN: SCHEELITE IN FOOTWALL QUARTZ

Comment (Production): $40000 IN AU.

Comment (Location): NEW LONDON VEIN: NORTHEAST SLOPE HUNTER MTN (NW/4 SEC. 12); HOMESTAKE VEIN: CREST OF LARGE SPUR HALFWAY DOWN EAST SIDE HUNTER MTN; HOMESTAKE-LONG ADIT: EAST OF HOMESTAKE VEIN; MINERALITE VEIN: SE/4 SEC. 13 ABOUT 100 FT ABOVE HWY; ROOSEVELT VEIN: NE/4 SEC 8 ON EAST SIDE OF RIVER; TUNGSTIC VEIN: 1400 FT NORTH OF UPPER ROOSEVELT ADIT; MILWAUKEE VEIN: SE/4 SEC. 7 ABOUT 100 FT ABOVE RIVER.

Comment (Workings): NEW LONDON VEIN: LARGE OPEN CUT, 2 UNDERGROUND LEVELS. MAIN ADIT IS 350 FT LONG WITH STOPES BOTH ABOVE AND BELOW. 75 FT WINZE CONNECTS THIS LEVEL WITH LOWER LEVEL WHERE A DRIFT, WITH SOME STOPING, HAS BEEN DRIVEN FOR 100 FT ALONG ORE BODY.; HOMESTAKE VEIN: 50 FT SHAFT WITH 30 FT DRIFT AT BOTTOM FOLLOWING VEIN NORTHWARD.; HOMESTAKE-LONG ADIT VEIN: ADIT DRIVEN WESTWARD REPORTEDLY FOR 850 FT ON NEARLY VERTICAL VEIN.; MINERALITE VEIN: SEVERAL SMALL OPEN CUTS; ROOSEVELT VEIN: 2 ADITS DRIVEN EASTWARD. 700 FT LONG LOWER ADIT IS ABOUT 1700 FT EAST OF RIVER AND ABOUT 200 FT ABOVE IT. 140 FT LONG UPPER ADIT IS ABOUT 200 FT HIGHER; TUNGSTIC VEIN: NO WORKINGS; MILWAUKEE VEIN: 125 FT ADIT DRIVEN EASTWARD ON VEIN.

Comment (Geology): NARROW INCLINED DIKE ALONG NEW LONDON VEIN IS CUT BY 3-4 FT WIDE VERTICAL BASIC DIKE (N60E). SOUTHWARD (UPPER) PART OF INCLINED DIKE HAS BEEN FAULTED SEVERAL FT UPWARD ALONG VERTICAL DIKE RELATIVE TO LOWER PART. ORE BODY IS IN THE PART OF THE VERTICAL DIKE BETWEEN FAULTED PARTS OF THE INCLINED DIKE AND HAS SAME MINERAL COMPOSITION AS NARROW VEIN. ORE BODY IS CUT BY SEVERAL REVERSE FAULTS (ABOUT N75W, 55SW). EACH FAULT DISPLACES UPPER PART OF ORE BODY AS MUCH AS 10 FT TO THE NE.

Comment (Deposit): 4 CLAIMS ON EAST SIDE OF HUNTER MTN ON WEST SIDE OF METHOW RIVER AND AT LEAST 3 CLAIMS EAST OF RIVER. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
