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 (Reserve-Resource): ESTIMATE IS TO A DEPTH OF 10 FEET. TOTAL RESERVES ARE MUCH LARGER.

Comment (Location): INFO FROM LAND.ST :(1964)

Comment (Development): WHITEHALL CORP. WAS OPERATOR IN 1962. DURING 1984-86, FANSTEEL CARRIED OUT SURFACE DRILLING PROGRAM AND MINED BULK SAMPLE FOR METALLURGICAL EVALUATION.

Comment (Geology): HOST ROCK IS HORNBLENDE GNEISS AND QUARTZ-HORNBLENDE-BIOTITE GNEISS AND SCHIST.

Comment (Deposit): THE MAIN PEGMATITE COMPRISES FIVE WELL DEFINED ZONES. (1) A DISCONTINUOUS OUTER SELVAGE OF QUARTZ, ALBITE, MUSCOVITE, AND SCHORL, ALSO MICA. (2) THE WALL ZONE ( 2 TO 55 FEET THICK ) OF PERTHITE, QUARTZ, ALBITE, AND MUSCOVITE IS MOSTLY COARSE GRAINED. (3) THE OUTER INTERMEDIATE ZONE IS COARSE GRAINED BLOCKY PERTHITE. TOURMALINE IS LOCALLY ABUNDANT. (4) THE INNER INTERMEDIATE ZONE HAS VERY COARSE PERTHITE AND MASSES OF QUARTZ. (5) THE CORE IS ARBITRARILY DESIGNATED AS HIGHER GRADE FELDSPAR THAN THE PREVIOUS ZONE. BISMUTH MINERALS FORMS VEINLETS AND STOCK WORKS WITHIN THE QUARTZ-RICH PEGMATITE, ALSO AS SCATTERED IRREGULAR MASSES. THE BISMUTH MINERALS ARE THEMSELVES TRANSECTED BY VEINLETS CONTAINING WULFENITE, VANADINITE, PYROMORPHITE, MIMETITE, ANGLESITE, CERUSSITE, CHRYSOCOLLA, CUPRITE, AND FLUORITE. NATIVE SILVER AND MOLYBDENITE ARE DISSEMINATED THROUGH SOME MASSES OF BISMUTITE AND BEYERITE.

Comment (Workings): WORKINGS INCLUDE OPEN CUTS (MAIN CUT: 90 FT BY 35 FT BY 20 FT DEEP; BISMUTH CUT) AN INCLINE (20 FT) AND SEVERAL IRREGULAR TRENCHES, PITS, AND CUTS
