The operation consists of two open pits in the Saddleback Greenstone Belt, a fault bounded sliver of Archaen volcanic and shallow level intrusive rocks surrounded by granite and gneissic rocks. The main zone of gold mineralisation occurs over a strike length of more than five kilometres and a width of approximately one kilometre.

The mine operates two pits (North & South Pits) utilizing three CAT electric shovels and 39 CAT 793 haul trucks. Boddington has a current capacity to mine approximately 235,000 tonnes of material per day.

The milling plant includes a three stage crushing facility (two Primary crushers, six Secondary crushers and four high pressure grinding rolls), four ball mills, a flotation circuit and carbon in-leach circuit.

At Boddington, ore containing copper and gold is crushed to a coarse size at the mine and then transported via conveyor to a process plant, where it is further crushed and then finely ground as a slurry. The ore is initially treated by successive stages of flotation resulting in a copper/gold concentrate containing approximately 15% to 20% copper. Flotation concentrates are also processed via a gravity circuit to recover fine liberated gold and then dewatered and stored for loading onto ships or rail for transport to smelters. The flotation tailings have a residual gold content that is recovered in a carbon-in-leach circuit.

The scavenger tailings leach circuit consists of two parallel trains of 12 leach tanks. Cyanide and oxygen are added to the slurry to leach the gold, and carbon is pumped in a counter-current direction to adsorb the leached gold. Activated carbon added to the scavenger tailings adsorption circuit is recovered and treated by conventional split-AARL (Anglo-American Research Laboratory) elution and reactivated in horizontal reactivation kilns. Gold recovery from the split-AARL pregnant electrolyte solution is by electro-winning, cathode sludge filtration, drying and smelting.
