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): VEINS CONTAINING MANGANESE MINERALS ARE ASSOCIATED WITH THE BRECCIAS OF CALC-LATITE IN THE CIENEGA AREA. OUTCROPS ARE FOUND 1,000 FEET NORTHWEST OF THE DAM AND 1300 FEET SOUTH OF THE DAM. X-RAY ANALYSIS OF SAMPLES OF VEIN MATERIAL COLLECTED JUST WEST OF THE DAM INDICATED THE PRESENCE OF PYROLUSITE IN A MATRIX OF QUARTZ, HEMATITE, AND SOME MONTMORILLONITE; THE MATRIX IS PINK (KOTTLOWSKI, 1963, P. 80). THE MANGANESE OCCURS IN INTERLACING SEAMS, NARROW STRINGERS, AND BUNCHES IN THE SHEARED AND BRECCIATED ZONE.

Comment (Workings): WORKINGS CONSIST OF SEVERAL PROSPECT PITS NEAR OUTCROPS BOTH 1000 FEET NORTHWEST OF THE DAM AND 1300 FEET SOUTH OF THE DAM.

Comment (Location): THIS DEPOSIT IS NOT LOCATED IN ANY FORMAL MINING DISTRICT OR AREA. THE LOCATION IS ACCURATE FOR THE "T" CORNER OF SECTIONS 5 AND 6, T. 15N., R.8E., AND SECTION 32, T. 16N., R. 8E. ; INFO FROM LAND.ST :1979
