| The Dugald River Lode was discovered prior to 1881 but has never been mined. The deposit is a classical example of a stratabound |
| zinc-lead sulphide accumulation in a graphitic black shale. |
| The main sulphide minerals in order of decreasing abundance are pyrrhotite, sphalerite, pyrite and galena in a gangue of graphitic shale |
| and slate, quartz and carbonates. The ore is banded, with sulphide bands alternating with graphitic shale bands. |
