Comments on the workings information

  • ACTIVITY INFO AS OF 1967, U N REF. PRODUCTION IS FROM AREA OF ANACONDA'S DRILLING AND SMALL LEACHING OPERATION. DEPOSIT ONLY WORKED BY PIQUENEROS WHO HAVE DUG OVER 50 PITS CONCENTRATED ON THE SHALLOW, SUPERGENE-ENRICHED ZONE.

Comments on development

  • U N DID GEOCHEMICAL AND GEOPHYSICAL SURVEYS AND GEOL MAPPING 1963-1966. ENAMI (CHILEAN GOVT ORGANIZATION)DRILLED A FEW WILDCAT EXPLORATION HOLES AT CHURQUE. THE MAIN PORPHYRY HAS BEEN EXPLORED BY ANACONDA, ENAMI, AND NORANDA; BULK-MINEABLE GOLD HAS BEEN INVESTIGATED BY FALCONBRIDGE, CHEVRON, AND DAYTON, THE LATTERMOST HAVING ORDERED A FEASIBILITY REPORT FOR AN OPEN-PIT, HEAP-LEACH OPERATION.
