Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Deposit): ACCORDING TO LIPMAN'S (1976) MAP, VEIN WOULD LIE IN ENE-TRENDING FAULT (DOWNDROPPED ON SE) THAT DISPLACES PRECAMBRIAN GRANITE ON NW AGAINST PICAYUNE MEGABRECCIA ON SE. WOOLSEY (1907) STATED THAT TUNNEL INTERSECTED FANNY VEIN THAT HAD BEEN SEEN ON OUTCROP, AND ORE CONSISTED CHIEFLY OF CHALCOPYRITE.
Comment (Workings): TUNNEL DRIVEN 1683 FT GENERALLY SE, WITH 300-FT NE CROSSCUT AND 100-FT SW CROSSCUT FROM FACE; RAISE OF UNKNOWN HEIGHT.
Comment (Location): MINE LOCATED ON HILLSIDE SE OF LAKE FORK GUNNISON RIVER 0.9 MILE SW OF WHITECROSS AND 1.35 MILE NNW OF HANDLES PEAK. SECTIONS LISTED INCLUDE THOSE COVERED BY STEINBECK'S CLAIMS. BON HOMME CLAIM LOCATED IN NW NE SEC. 03 (UNSURVEYED). ; INFO FROM LAND.ST :1977
Comment (Production): PARTIAL PRODUCTION RECORD. PRODUCTION FIGURES UNAVAILABLE FOR YEARS BETWEEN 1880S AND EARLY 1900S.
Comment (Commodity): BI NOT VERIFIED HERE BUT IS BASED ON BROWN'S (1926) GENERAL OCCURRENCE OF LILLIANITE IN AREA.
