PEA error?From the PEA: "DSO only processing rate of 0.6 Mtpa for 3.5 years resulting in total production of 248 kt Cu and 649 koz Au. Phase 2 Main Mine processing rate of 2 Mtpa resulting in an additional total production of 507 kt Cu and 184 koz Au (mine gate figures). DSO material of 1.91 Mt, mined at an average grade of 13.0% Cu and 10.6g/t Au and Phase 2 Main Mine material mined at average grade of 4.6% Cu and 2.9 g/t Au." Phase 2 Main Mine will process 13.3 Mt material, the grade is 2.9 g/t Au and total Au is roughly 1.2 million oz. Only 184 koz gold will be produced that's a recovery rate of 15%. Why the Au recovery rate is so low?
