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.

Analytical Data
Analytical Data: BULK SAMPLES FROM PROSPECTS CONTAINED 6 AND 30 OPT AG. SAMPLES ANALYZED BY KENNECOTT'S SMELTER LAB CONTAINED 22 TO 84 OPT AG, 0.048 TO 0.013 OPT AU, 0.1 TO 0.9 % CU, 0.9 TO 10.3 % PB, 58.8 TO 87.7 % SIO2, 0.039 TO 0.725 % AS, 0.005 TO 0.67 % SB, 1.24 TO 3.7 % BI. IN GENERAL A HIGH CORRELATION EXISTS BETWEEN PB, AG, AND BI.
Analytical Data: A SIMILAR SAMPLE (DOME HILL-2) CONTAINED 200 PPB AU, 39.4 PPM SB, 124 PPM AS, 310 PPM CR, 1.0 % FE, < 2 PPM MO, 8 PPM AG, 15 PPM W, <200 PPM ZN, 1100 PPM ZR, 220 PPM CU, 890 PPM PB, AND 8 PPM BI
Analytical Data: THREE SAMPLES COLLECTED BY THE UGMS YIELDED THE FOLLOWING RESULTS: SAMPLE 23-27 WAS COLLECTED FROM THE NORTHERN PIT AND CONTAINED 13 PPB AU, 21.6 PPM SB, 98 PPM AS, 47 PPM CE, 430 PPM CR, 1.8% FE, 4 PPM MO, <5 PPM AG, <200 PPM ZN, 880 PPM CU, 640 PPM PB, <1 PPM BI: A SAMPLE OF SILICIFIED QUARTZITE WITH QUARTZ STOCKWORK AND LIMONITE STAIN CONTAINED (DOME HILL-1) 140 PPB AU, 472 PPM SB, 165 PPM AS, 56 PPM CE, 280 PPM CR, 1.7% FE, 18 PPM MO, 15 PPM AG, 8 PPM W, <200 PPM ZN, 205 PPM CU, 3200 PPM PB, AND 36 PPM BI

Comments
Comment (Development): PROPERTY EXPLORED BY GETTY, PHELPS DODGE, WESTERN STRATEGIC MINERALS, AND OTHERS. MOST RECENT EXPLORATION BY FREEPORT IN 1987. WESTERN MINING BEGAN EXPLORATION PROGRAM IN 1989 (SPRING).
Comment (Workings): WORKINGS CONSIST OF THREE PITS NEAR THE CREST OF DOME HILL AND ONE PIT TO THE NORTHWEST. NUMEROUS HOLES HAVE BEEN DRILLED AT DOME HILL AND THE AREA TO THE NORTH.
Comment (Geology): GRANODIORITE IS EXPOSED ABOUT 1 MILE SE OF DOME HILL AND IS THE NEAREST KNOWN INTRUSIVE ROCK.
Comment (Deposit): ORE IS PRESENT AS VEIN, STOCKWORK, AND REPLACEMENT OCCURRENCES. HOST QUARTZITE IS SILICIFIED AND CONTAINS LOCAL PATCHES OF FINE-GRAINED, DISSEMINATED SULFIDE REPLACEMENT. HOST IS ALSO CUT BY NUMEROUS VEINS AND STOCKWORK VEINLETS OF OF QUARTZ. MOST VEIN QUARTZ IS FINE GRAINED, BUT LOCAL COARSE COCKSCOMB QUARTZ IS PRESENT. MOST ORE APPEARS TO BE THE OXIDE REMAINS OF PRIMARY SULFIDES. PRIMARY SULFIDES ARE TETRAHEDRITE-TENNANTITE, GALENA, CHALCOPYRITE, AND PYRITE.
