Grab samples collected for preliminary metallurgical test work assayed 5% lead, 10% zinc and 119g/t silver.
First flotation testing on grabs sample material yielding recoveries of over 96% Pb, 94% Zn and over 80% Ag respectively.
Lead and zinc flotation concentrate grades were over 50% Pb and 56% Zn respectively, and silver recoveries were 80%.
The mine is now largely free of water with only small pockets remaining and no detectable
recharge and the lower levels were found to be in generally good condition.
Engineering study work is continuing and the delivery of final survey data from the dewatered areas will allow the underground design work to be completed and development costs to be assessed.
