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 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 consists of the consolidated Waroonga and New Holland underground complex. The underground workings are accessible from the Waroonga and New Holland Pits. At Waroonga, underground production and development are carried out by contract miner Barminco Limited. At New Holland, underground production, development, maintenance as well as all High Voltage and Low Voltage electrical works is conducted by a dedicated Gold Fields employee team.

Processing Plant

The Agnew processing plant has a capacity of approximately 1.3 million tonnes per annum treating fresh ore from the New Holland and Waroonga underground mines. The plant consists of a tertiary crushing circuit, a two stage grinding circuit composed of a 1.1MW primary ball and 1.1MW secondary ball mill, gravity recovery including two 40” Knelson concentrators and a Gekko In-line Leach reactor, three Leach and six Carbon-in-Pulp (CIP) pachuca tanks, pressure Zadra elution circuit and an in-pit tailings storage facility.

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 as well as the first mine in the world to utilise wind generation at a mine site.

The Agnew microgrid consists of a 16MW gas and 3MW diesel generation, 4MW solar generation from the solar farm, wind turbines that will generate 18MW, a 13MW/4MWh battery energy storage system and an advanced micro-grid control system. Since the commissioning of the microgrid, 55% of Agnew’s electrical power is renewable source power and depending on the right conditions, over 80% of all of site’s electrical power is generated by the five 110m tall wind turbines and solar farm.

The microgrid project in conjunction with the new Village as well as planned Greater Agnew infrastructure upgrades demonstrates Gold Fields’ commitment to sustainability and innovative solutions that will benefit all of our stakeholders now and into the future.
