| Comments |
| Mount Morgan was the largest single lode gold orebody in Australia. The deposit occurs within a thick pile of acid pyroclastics of sodic |
| rhyolite or dacite composition. |
| The orebody is described as a pipe like body which transgresses the stratigraphic sequence. The two main types of ore recognised were |
| massive pyrite-silica mineralisation (Main Pipe Orebody) and siliceous stringer mineralisation (Sugarloaf Orebody). |
| The Main Pipe and Sugarloaf orebodies were recorded as being continuous with a gradation observed in the lower part of the Main Pipe |
| from massive pyritic ore through semi-massive siliceous sulphides to siliceous stringer mineralisation. |
