This speciman is hydrated sesquioxide of iron from Port Molyneux. It yielded:—
| Water | 14 per cent. |
| Oxide of iron | 65.5 per cent. |
| Earthy matter (clay silica) | 20.5 per cent. |
This is equal to 46 per cent, of metallic iron. If there is a large quantity of this ore near a good coal field, it should take a good place among the industries of the future. The small quantity of silica present (about 10 per cent.) will not require much lime for its removal.
