| Comments |
| Three main styles of mineralisation have been identified, a massive pyrite body, a supergene enriched copper ore and an inferred oxide |
| resource. In addition massive lead-zinc barite lenses are noted. |
| Felsic lavas and fragmentals of rhyolite to rhyodacite composition dominate the host sequence with feldspar destructive alteration |
| commonly present, producing assemblages dominated by feldspar and quartz. |
| A zone of intense chlorite-anhydrite alteration occurs immediately beneath the massive pyrite body with intense clay alteration developed |
| at its margins. |
