The Ahafo mine is composed of three orogenic gold deposits that have oxide and primary mineralization. The gold is hosted in brittle shear zones cutting granitic intrusives that have kilometer-scale vertical and lateral extent. Gold occurs primarily in pyrite and secondarily as native gold in quartz veins.

The Ahafo mine has two active open pits, Subika and Awonsu. Subika added an underground operation, which reached commercial production in November 2018, and Awonsu is progressing towards future laybacks.

The available mining fleet for surface mining consists of three shovels and thirty-eight 141-tonne haul trucks. The available mining fleet for underground mining consists of five underground loaders and eight haul trucks, each with a 60-tonne payload. The daily production rate is approximately 95,000 tonnes.

The processing plant was commissioned in 2006 to process 7.5 million tonnes of primary and oxide ore per year. With the depletion of oxide ore, the current plant throughput has decreased to 6.5 million tonnes per year. The processing plant consists of a crushing plant, a grinding circuit, carbon in leach tanks, elution circuit, counter current decantation circuit and a tailings disposal facility.

The Ahafo Mill Expansion, an ongoing development project, will expand the existing plant by approximately 3.5 million tonnes per year through the installation of a new crusher, a single stage SAG mill and two leach tanks.

The expansion is expected to have an average annual gold production of between 75,000 and 100,000 ounces per year for the first five years beginning in 2020. Both first production and commercial production are expected in the second half of 2019.
