A reduction of the top size of the ROM, which allowed the primary crusher to operate with a higher feed rate by 2.2%, a reduced opening, and to feed the SAG with a smaller top size. Operating the SAG with more fines (<10mm) by increasing the powder factor to 2.78kg/m 3, increased the plant production rate by 10.7% while using the same power.
