| Mineralisation Age |
| 40AR/39Ar date on sericite alteration of ~308Ma |
| (Perkins & Kennedy, 1998). The mineralisation |
| developed from multiple events over the period |
| 320MA to 280Ma (Nethery and Barr, 1996). |
| Comments |
| This resource was delineated by Niugini Mining Ltd 2.6km north-west of the Red Dome pit and includes both a resource amenable to |
| open pit extraction and the Mungana Deep resource which is below that amenable to open pit extraction. |
| The project was considered only marginally economic by Niugini Mining Ltd who noted that complex metallurgy detracts from the |
| marketability of the gold/copper and lead/zinc concentrate that would be produced. |
| The Mungana deposit can be categorised as a low sulphidation porphyry Cu-Au skarn deposit developed within carbonate host rocks with |
| attributes of a low sulphidation porphyry Cu-Au system developed within aluminosilicate host rocks. |
| The mineralising system is highly telescoped and multiphased with seperate hydrothermal events spanning ~35My. The final overprinting |
| hydrothermal phase can be categorised as a structurally controlled high sulphidation system (MSc M. Barr) |
