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.

Comment (Production): PROPERTY IN SEC. 25 WAS WORKED BY LESSEES IN 1917, WHO PROSPECTED AND PERFORMED SOME DEVELOPMENT WORK. SOME OF THE LARGER PATCHES IN SEC. 34 WERE WORKED AT THE MAGNESIA MINE. AS THESE AREAS LIE IN A RATHER DEEP CANYON , A BRANCH OF THE ARROYO DEL VALLE, TRANSPORTATION WOULD BE DIFFICULT AND EXPENSIVE. V.N LS NO.2 LISTS ONLY 34 AND 35. BIM SAY NO MINERAL IN S 1/2 SEC. 34
