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 (Geology): SHEAR ZONE MINERALIZATION IS CHARACTERIZED BY A PINCH-AND-SWELL TYPE OF STRUCTURE THAT DEFINE PODS OF SHEARED AND BRECCIATED STRONGLY ALTERED GRANODIORITE, 2 TO 4 FEET WIDE AND ABOUT 10 FEET IN DIAMETER.

Comment (Deposit): LOCATED ALONG SOUTHEASTERN MARGIN OF A LARGE GRANODIORITE STOCK ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Location): IN TRINITY CANYON. ACCESSIBLE VIA POOR ROAD ALONG ACTIVE STREAM COURSE. . INFO FROM LAND.ST :(1972)

Comment (Production): UNKNOWN AMOUNT

Comment (Development): AREA WORKED BETWEEN 1859 AND 1915. NO ACTIVITY AT TIME OF EXAMINATION IN 1984.

Comment (Workings): 2 ADITS ABOVE THE HAPPY JACK SPRING IN TRINITY CANYON.

Comment (Deposit): WORKINGS ALONG A SHEAR TRENDING N40-50E AND DIPPING 50-70NW. IRON OXIDE ALTERATION, SOME BRECCIATION. MINERALIZATION IS IN WISPY STREAKS IN THE QUARTZ AND EXTENDS INTO THE GRANODIORITE. ANDESITE OR MAFIC DIKES OCCUR NEARBY, EAST OF THE MAIN WORKINGS. SAMPLE 2830 IS OF BRECCIA AND QUARTZ VEIN MATERIAL WITH SULFIDES.
