A huge tick for Bulla Park. Amenable to simple rougher flotation (note that they didn't do any cleaning, just single pass rougher). Those are some seriously good con grades 19% Cu and 7.5% Sb with some 270 g/t silver credits for a first pass rougher from ~0.35% Cu feed.
The Con2 at 3% mass pull (nothing) but 94% Cu 91% Sb recovery is excellent. Option on the table to carry out a low cost rough grind up front, pull 5% mass and then follow up with a finer grind and make something closer to the Con1 grade but now at 90-95% recovery... Or could ore sorting work given the sulphide mineralogy sticks out like dogs balls in the drill core?? The big question, is this mixed Cu/Sb concentrate saleable or will the [Chinese] offtakers be looking to bend WC1 over a barrel on payable terms? Their commentary around separating the copper and antimony looks like two high value products are being targetted. Looking forward to follow up testing.
