Economic information

Comments on the geologic information

  • MAIN ORE BODY WAS ALONG S EDGE OF WEDGE-SHAPED FAULT BLOCK OF LIMESTONE. IGNEOUS CONTACT IRREGULAR, WITH TONGUES OF GRANITE IN LIMESTONE AND MINERALIZED INCLUSIONS OF LIMESTONE IN GRANITE. FOUR DIABASE DIKES FOLLOW PLANES OF PRE-EXISTING FAULTS. TWO OF THE DIKES BOUNDED MAIN ORE BODY.

General comments

Subject category Comment text
Deposit SCHEELITE OCCURS IN SEVEN LENSES OF TACTITE AND IN AN IRREGULAR QUARTZ-MUSCOVITE VEIN. LARGEST ORE BODY INTERSECTED AT DEPTH OF 9 M BY ADIT. THREE OTHER TACTITE LENSES OPENED TO DEPTHS OF 3 M BY MEANS OF PITS AND SHALLOW SHAFTS. W VEIN CROPS OUT IN GRANITE ABOUT 10 M S OF THE ADIT PORTAL.
Deposit SALES OF ORE FROM THE HERMOSILLO DIST. DURING 1943 AMOUNTED TO ABOUT 2,800 UNITS OF WO3 FROM THE MARIA LUISA, TUNGSTENO, NOCHE, CUATE, AND SANTA EDUVIGES MINES. IN ADDITION, AT THE END OF 1943 ORE GRADING BETWEEN 1.3 1ND 2.0 % WO3 (CONTAINING ABOUT 1,640 UNITS OF WO3) WAS STORED ON DUMPS DUE TO SUBECONOMIC GRADE. ; INFO.SRC : 1 PUB
