re: Ann: Project Updates - Barnes Hill and Li...
Not a problem.
Basically he was trying to determine the purity of the Cu sulphide ore if you can release it from the quartz gangue how much was chalcopyrite and potentially how much pyrite might be mixed up in it. Basically if it was 100% chalcopyrite it would be 34.63% Cu. Through his calculations he ended up with 30% Cu, so it is mostly chalcopyrite.
Unfortunately no real information is provided about the trace Au and Ag to make any real comment.
