  • (1) POSITIVE; (2) PROBABLE; (3) POSSIBLE; LOCATION OF RESERVES NOT GIVEN.
  • (1) UBINA-IRMA ZONE; (2) JAYAJ MAYU MANTO; (3) NORMANDIA MANTO.

Comments on the workings information

  • SHORT TUNNELS AND CROSSCUTS; OPEN CUTS
  • WIDER PORTIONS OF VEINS AND MANTOS WORKED BY ADIT TUNNELS, NOW MOSTLY CAVED. NUMEROUS SURFICIAL PROSPECT PITS AND TRENCHES. WORKING ARE ALL SMALL, OVER A MAXIMUM VERTICAL INTERVAL OF 150 M WITH ONLY A FEW 100 M TOTAL OF HORIZONTAL WORKING.

Comments on development

  • UBINA AND IRMA MINES WORKED BY HOCHSCHILD FROM 1949 TO 1952. HOCHSCHILD MINES WERE NATIONALIZED IN 1952 AND PASSED ON TO COMIBOL. COMIBOL HAS NOT OPERATED ITS PROPERTIES. THE SANTA BARBARA MINE WAS LEASED TO COOPERATIVA DE PULACAYOS. ; ECON.COM: HAND SORTING; PRIMITIVE GRAVITY CONCENTRATION MILL AT TRES HUGOS MINE. HOCHSCHILD PROCESSED ORE MINED AT UBINA-IRMA AT ITS MILL AT THE PULACAYO MINE 30 KM TO NW BY ROAD.

Deposit SEVEN VEINS WITH ORE SHOOTS 40 M LONG AND AVERAGE 0.45 M WIDE. MOST VEINS STRIKE E-W.
Deposit DISTRICT CONSISTS OF THE UBINA-IRMA STOCKWORK ZONE, THE SANTA BARBARA-NORMANDIA-JAYAJ MAYU MANTO DEPOSITS, WITH WELL-EXPOSED FEEDER VEINS, AND THE TRES HUGOS VEIN. THE PROPYLITIZED QUARTZ DIORITE STOCK OCCURS IN THE NORTH PART OF THE DISTRICT. AG-PB-ZN-SB-SN-CU MINERALIZATION IN MANTOS LIE WITHIN THE CONTACT METAMORPHIC AUREOLE AROUND THE QUARTZ DIORITE STOCK. FURTHER SOUTH IS THE ZN-W-SN VEIN MINERALIZATION AT THE TRES HUGOS VEIN, AND FURTHEST SOUTH IS THE UBINA-IRMA AG-PB-ZN-CU STOCKWORK ZONE. VERTICAL ZONING FROM DEEPER SN-W MINERALIZATION TO UPPER AG-PB-ZN MINERALIZATION IS APPARENT. UPPERMOST PARTS OF VEINS AND STOCKWORKS CONTAIN CHALCEDONIC QUARTZ AND BARITE. PREFERRED ORIENTATIONS FOR VEINS AND VEINLETS ARE N30-80E AND N10-45W. MANTOS ARE SUBVERTICAL TO 80NE DIP, STRIKING N10-40W.
