A re-examination belt has revealed widespread IOCG-type mineralization exposed numerous veins, stockworks, breccias, replacement zones extensive areas polyphase hydrothermal alteration. effects are most visible intense andesite, but also affect associated synvolcanic intrusions. weak, pervasive chlorite-epidote-carbonate-sericite alteration is observed least-altered volcanic rocks. Subsequent progressively superimposed on earlier facies includes: sericitic (sericite, quartz); phyllic quartz, pyrite); potassic (K feldspar); earthy specular hematite; K feldspar-scapolite-albite-magnetite-actinolite-apatite as stockwork, pegmatitic recrystallization; feldspar-tourmaline-Fe-oxide-silica-sulfides; massive albitites locally laced with amphibole. Hydrothermal breccias diatremes occur throughout belt. style, size, overprinting relationship, mineralogy, chemical composition support current IOCG exploration model well elsewhere zone overall.
