Comments on exploration

  • EXTENSIVE EXPLORATION TOOK PLACE WITH THE SOVIETS TILL 1989. MIRAMAR, WHO SOLD ITS RIGHTS TO NORTHERN ORION IN 1995, CONFIRMED THE SOVIET WORK IN EARLY 1995. AT THE SAME TIME, MIRAMAR DISCOVERED THAT THE TOP OF THE COPPER DEPOSIT, THE ZONE, HELD SIGNIFICANT GOLD VALUES. MINERALIZATION IS OF VOLCANOGENIC EXHALATIVE ORIGIN AND CONSISTS OF PYRITE AND CHALCOPYRITE. SECONDARY ENRICHMENT THROUGH WEATHERING HAS RESULTED IN A SUPERGENE COPPER ZONE COMPRISED MOSTLY OF CHALCOCITE AND CUPRITE.
