The most notable results observed in test Sep-F1 show the rougher stage produced a copper concentrate
assaying 18% Cu at 60% recovery. This test featured a copper rougher tail producing a final Ni
concentrate of 7.5% Ni at 51.5% recovery. Bulk cleaner in this test observed recoveries of 76% and 52%
for copper and nickel respectively into the final 3 rd cleaner concentrate at a grade of 15% Cu+Ni. Cu/Ni
separation test results are presented in Table 12. Detailed test results are attached in the Appendix E.
