As noted earlier, copper minerals and gold tend to concentrate in the finer size fraction in the SAG mill trommel undersize. If the metal distribution is compared on a size-by-size basis, it was found that SAG mill trommel undersize sample contained richer copper content than the cyclone underflow in the fine size fractions.

The results show that the mineralized material is of moderate competency and hardness and is amenable to grinding in a conventional SAG mill / ball mill circuit. Flotation testing indicated that 85.6% of the copper and 60.8% of the gold are recovered to the final concentrate, which results in a concentrate grade of 30% copper and 21 g/t gold.
