| Deposit | TWO RHYOLITIC DOMES WITH NUMEROUS PROSPECTS AND MINES. MAGALLANES IS THE LARGER OF THE TWO, COVERING APPROXIMATELY 5 KMS N-S BY 7 KMS E-W. MAGALLANES APPEARS TO BE SITUATED WITHIN AN AXIAL TROUGH OR GRABEN. THE MINERALIZATION HAS OCCURED ALONG FRACTURES CONTROLLED BY THREE 2-3 KM LONG SUBPARALLEL NORMAL FAULTS 600 M APART. ASSAY DATA SHOW THAT THE HIGHEST CONCENTRATIONS OF GOLD, FLUORITE, AND SILVER OCCUR IN BRECCIATED FAULT ZONES. |
| Deposit | THE COMBINATION OF QUARTZ-RICH RHYOLITES, FLUORITE, MANGANESE, AND SOME MOLYBDENUM IS COMPATIBLE WITH AN OVERALL ASSOCIATION CHARACTERISTIC OF A MOLYBDENUM-PORPHYRY TYPE OF SYSTEM, ALTHOUGH AT PRESENT LEVELS OF EROSION THE DEPOSIT APPEARS TO BE AN EPITHERMAL GOLD-SILVER TYPE. ; INFO.SRC : 1 PUB |
