100% ore! Avg 40g/t Au 1km x 200m to EOH all holes, OP mining 2019, page-802

weird how ANN's are not showing on HC this morning.
Had a quick read a little concernd about this:

Tests on 25g samples of Ema surface dolerite and quartz-porphyry drill hole material commencedin late January 2019, utilising the preferred smelt conditions and cupellation and partitioningmethodology. Five flux combinations and various combinations of copper lead and silver ascollector are being used. All tests utilise basic fire-assay principles involving fusion of a 25gsample with a specific flux and collector metal, cupellation of the resultant collector button to forma precious metal prill, subsequent parting of the prill and weighing of the resultant gold, and,where obtained, silver and palladium buttons. Where silver is added as a collector the weight ofadded silver is subtracted in calculating the final silver grade.

All fine for assays, but for production the need to work some thing that gets decent recoveries on all the ore, don't want 5 plants and using precious metals to extract the goods.

PS i am pretty clueless in regards to these metallurgy processes they are talking about.
