Reasonable grades to start from, with scope for much improvement. Note that the ore is 'part buried beneath thin cover'and that the extent of AU and AG still needs to be established - their presence is expected in polymetalic VMS deposits, and when decent seams are found they can become the backbone of a mine development scheme thanks to rapid payback.
[Au and Ag reported to concentrate in some metallurgical samples allowing further upside potential from precious metals...Au grade in nine of those ore samples was reported within 0.1-0.4 g/t, and Ag grade as 4.2-22.9 g/t, however, no information of Au and Ag grade in concentrates and recovery of precious metals was provided. In previous metallurgical studies Au and Ag grades in polymetallic concentrates reported from 6-20 g/t and 46-496 g/t respectively with best Ag grades associated with high grade Pb. Additional data is required to understand grade distribution and potential upside of byproduct Au and Ag within a precious-metal mineralised system.]
