5hareholder,
Can you show me specifically where the AVB deposit is made up of NCu in the same manner as CDU? The Native Copper nugget effect is real and the jorc model does not account for it in CDU's case.
Purity of Ncu nuggets (99%) has a proven impact on sample recovery via RC in Las Minerale and Sth Rocklands, and should not be confused with a highly oxidised zone without any copper nuggets.
In relation to AVB, I've only ever seen evidence of their high grades (+25% CU) being Chalcocite (Cu2S), in the supergene with sulphide and oxide copper.
They do have an exceptionally high grade JORC resource of
210,000t at 11.65% copper, containing 24,400t of copper....!
