Based on the design throughput and moderate competency ore characteristics, a single 60 x 89 gyratory crusher is considered the most suitable for the primary crushing duty for the initial plant and Phase 2 expansion. For the 120 kt/d expansion, two crushers will be required. The primary crushers will be located at the edge of the ROM pad.

Haulage costs in mining operation are significantly raised with the increase in the diesel prices. Therefore, the movable plans, such as the mobile and semi-mobile haulage system, are the alternatives to replace trucks and reduce haulage costs. Regarding the various criteria used in the selection of the suitable haulage alternatives, a multi-criteria decision-making problem can be considered
