They have already got good float con grades in con 1 at 19.4% Cu.. anything around 15-20% copper is "acceptable" with 25% being good but have to keep an eye on the penalty elements which surprisingly antimony can be one. Additionally, if there are precious metals, like Ag, then you can get away with lower Cu. It looks like the Cu/Sb/Ag are all locked together so if we get higher grade Cu we also get higher grade Sb + Ag, perfect storm for metallurgy.

Based on the below, 50% of all copper concentrates (by count) globally are between 14 and 27% Cu. Average global silver grade is only 0.007% = 70 g/t compared to 200-270 g/t in Bulla Park.


From the next round it would be good to see repeatability (prove to market it wasn't an outlier) and if they can hit that 15-20% Cu but at the 90%+ recovery mark then we are cooking. I am expecting they will, given these results were a single rougher compared to a more conventional rougher + scavenger + cleaner 1-3 circuit that is employed on nearly every float plant.

Also keen to see if they can separate the antimony, now that could spark the interest of certain global entities..
