Situated in the Eastern Goldfields region, our Agnew mine site is 23 kilometres west of Leinster, 375 kilometres north of Kalgoorlie and nearly 1,000 kilometres north-east of Perth. Acquired in 2001, Agnew Gold Mine produces over 250,000 ounces of gold per annum.

Gold is sourced from the two underground operations and processed via a CIP plant. The majority of our nearly 650-strong Agnew workforce lives permanently in Perth and commutes to site on a fly-in/fly-out roster.

Our people fly to site on a chartered jet departing Perth Airport’s Terminal 2 twice weekly. Flight time to Leinster is approximately 60 minutes. The Leinster airport is approximately 15 kilometres from the town of Leinster, which in turn is approximately 23 kilometres from the site with the majority of our staff based at Agnew Village.

Camp life
The Agnew Village is 1.7kms from the Agnew Mine Site and offers a suite of services to our fly-in-fly-out workforce including free use of gym, recreation facilities complete with games, a wet mess and outdoor sports facilities.

Meals are provided at the company’s expense via the Agnew Village dry mess facility. Accommodation includes an ensuite single room with fridge, colour TV, full Wi-Fi and a phone per room.

Mining operations
Mining operations at Agnew currently consist of the Waroonga Underground comprising of the Kim, Main and FBH lodes. The underground workings are accessible from the old Waroonga Pit, via the Kim decline which extends to more than 1,300 meters below the surface. Stopes are mined by mechanised sub-level stoping and backfilled using paste fill, with underground production and development carried out by contract miner Barminco Limited.

Access to the Lawlers underground is via the New Holland and Genesis Pits and mining is predominantly via long-hole stoping of the Sheeba, Genesis and Cinderella lodes.

Processing
The Agnew process plant has a capacity of 1.3 million tonnes per annum. The crushing and grinding plant feeds a gravity circuit and a conventional Carbon-in-Pulp (CIP) circuit. The gravity circuit includes a Knelson concentrator and an in-line leach reactor which recovers approximately 55 percent of total gold production. The CIP circuit includes leach and absorption tanks followed by a pressure Zadra carbon elution circuit. Currently, the overall metallurgical recovery averages around 93.5 percent.

Exploration and regional development
The mine has a large tenement-holding of over 600 square kilometres in the district. Along with finding new ore bodies, Gold Fields’ exploration strategy at Agnew is focused on increasing the ore reserve to greater than 1.5 million ounces, which equates to more than seven years’ mining life.

Renewable Energy Project
Agnew is leading the way in the transition to renewable power for off-grid mining operations.  The Agnew Hybrid Renewable Project is Australia’s largest hybrid renewable energy microgrid and the first to utilise wind generation at a mine site.

Stage 1 is a new off-grid 23MW power station incorporating 16MW gas and 3MW diesel generation and 4MW solar generation from the new solar farm. Stage 1 was completed in July 2019 and saw 10% of the mine’s electrical energy requirements coming from renewables.

Commissioning of Stage 2 is underway and due for completion in May 2020 and will see the mines renewable electricity fraction increase to 50-60%. This phase of the project is supported by the Australian Renewable Energy Agency and includes five wind turbines that will generate 18MW, a 13MW/4MWh battery energy storage system and an advanced micro-grid control system.

This project demonstrates that Gold Fields is committed to sustainability and innovative  power solutions and they are leading the way towards clean, renewable energy.
