| Comments |
| The Lady Loretta mineralisation occurs as a stratiform, massive sulphide lens within carbonate rich silts and shales, tightly folded into a |
| basinal structure. Three main ore types are recognised: stratiform ore comprising laminated pyrite-sphalerite- |
| galena mineralisation, high grade ore comprising banded, recrystallised sphalerite-galena sulphides, and barite-chert sulphide comprising |
| low grade iron sphalerite within recrystallised bands with pyrite. |
| Metallurgical testing program indicated the ore responded favourably to conventional flotation separation techniques at a grind size of 35 |
| microns. |
