Deposit VEINS TYPICALLY 0.1-0.25 M WIDE ALTHOUGH LOCALLY THEY ARE WIDER. VEINS MAIN ORE MINERAL IS WOLFRAMITE
Deposit NEARBY OCCURRENCES MENTIONED BY SCHULTZ, 1952, ARE MINERAL DE MORALES (TO THE N), LA DURA (TO THE NE), ACCESS IN 1952 WAS ONLY BY AIRPLANE TO LA GUADALUPANA. LA MESA LARGA IS 13000 M ABOVE THE MINE CAMP SCHULZE'S MAP IS PRETTY USELESS FOR LOCATION PURPOSES. ; INFO.SRC : 1 PUB LIT
