| This is the main deposit of the seven deposit making up the Roseby Copper Project of Universal Resources. Blackard is the largest |
| deposit and is likely to be the first deposit to be mined in any development. |
| The stratabound oxide ore contains native copper, copper in clays and micas, chalcocite and cuprite. The deposit is the result of |
| weathering of quartz-biotite-scapolite calc silcate containing sulphides (mainly bornite and chalcopyrite). |
| The seven deposits occur within a 20 km linear zone of anomalous bedrock copper geochemistry. Copper grades are remarkably uniform |
| throughout the deposits, commonly in the range 0.4 to 1.2% copper. Copper nuggets occur deeper in the weathering profile. |
