The mine design includes a single open-pit operation using three pit phases, including a pre-stripping year, with a peak mining rate of 26Mt of material a year. The mine is estimated to produce 4.4Mtpa of ore, which will be fed to the processing plant to recover minerals at a rate of 90.1% and produce an average of 159,325oz of gold a year.
Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.

Retreat mining is the last phase of a common type of coal mining technique referred to as room and pillar mining. Retreat mining is a process that recovers the support-ing coal pillars, working from the back of the mine toward the entrance, hence the word retreat. Room and pillar mining advance inward, away from the entrance of the mine.
Mining at the Aurora gold project began with Rory's Knoll open pit deposit, which is being mined to a depth of 160m at a rate of 5,000t a day, to be followed by the remaining deposits. Open benching and sub-level retreat mining methods are being applied at Rory's Knoll, reaching a depth of approximately 1,000m underground.
