Comments on development

  • GRAENGES INTERNATIONAL MINING HAS DRILLED AT LEAST 74 HOLES TOTALLING SOME 4020 M OF CORE AND PERCUSSION DRILLING (1984). SEVERAL AREAS OF ANCIENT WORKINGS AND AIRBORNE "INPUT" ANOMALIES HAVE BEEN TESTED BY DRILLING; AT THESE PROSPECTS TWO SULPHIDE BODIES HAVE BEEN DELINEATED. THE FAVORABLE HORIZONS IN THE REMAINDER OF THE NUQRAH BELT, WHICH HAVE MORE SUBDUED GEOCHEMICAL AND GEOPHYSICAL RESPONSES, DO NOT APPEAR TO HAVE BEEN SYSTEMATICALLY TESTED.

Deposit THINLY BEDDED, STRATIFORM PYRITE, SPHALERITE, CHALCOPYRITE AND GALENA WITH TRACES OF SILVER SULPHOSALTS AND GOLD-BEARING MINERALS ARE HOSTED BY AN INTENSELY FOLDED AND FAULTED ALTERNATING AND INTERDIGITATING SEQUENCE OF RHYOLITIC LAPILLI AND CHLORITIC TUFFS, RHYOLITIC BRECCIA, GRAPHITIC TUFFS, MARBLES AND CHERT OVERLAIN BY BASALTIC FLOWS. MOST OF THE MINERALIZATION IS ASSOCIATED WITH GRAPHITIC TUFF LAYERS.
Deposit Discovery Year: ANCIENT
