The Gruyere Gold Project was discovered by Gold Road in October 2013 on the South Dorothy Hills Trend, 25 kms north east of the Yamarna Belt discovery, Central Bore. It is located approximately 200lm east of Laverton in Western Australia.

On 7 November 2016, Gold Fields and Gold Road announced a 50:50 joint venture in the development and operation of the Gruyere Gold Project (including the Central Bore, Attila and Alaric deposits, and the YAM14 and Toto Prospects, collectively comprising 144km2) in Western Australia.

The Gruyere discovery is a significant gold deposit and the mineral resource has been defined as 148 million tonnes, grading 1.2 grams per tonne for 6.2 million ounces of contained gold, making it one of the largest underdeveloped gold deposits in Australia.

Camp Life

Stepping off the chartered plane (around 90-minute flight from Perth), employees can walk straight to their own king-single room at the camp.

Room amenities include a landline phone (enabling calls to anywhere in Australia), an ensuite bathroom, bar fridge, desk, TV and high-speed Wi-Fi including streaming capabilities.

The features of the camp include a tavern and extensive sporting facilities including a well-equipped gym, basketball court, driving range, mini-golf and an enclosed cricket court, to name a few.

Mining Operations

Mining operations at Gruyere currently consist of one main open pit that will be developed in stages to an approximate depth of 500 meters below the surface and is set to become one of the deepest open cut gold mines in Australia. All mining activities consisting of loading, hauling, drilling, blasting and equipment maintenance is carried out by a Mining Contracting company using large scale mining equipment. The current life of mine is extended to 2031 which includes Golden Highway satellite pits which approximately 30km from the main Gruyere mine.

With the first gold pour being in July 2019 it is estimated to produce in excess of 300,000 ounces per year.

Processing Plant

The Gruyere processing plant has a capacity of approximately 9.75 million tonnes per annum treating oxide, transitional and fresh ore from the Gruyere open pit mine. The plant consists of a single stage gyratory crushing circuit, a 15MW SAG and 15MW Ball mill (SABC) grinding circuit, gravity recovery including four 48” Knelson concentrators and a Gekko In-line Leach reactor, Pre-leach thickener, one Leach and six Carbon-in-Leach (CIL) agitated tanks, Split AARL elution circuit and a thickened downstream tailings storage facility.
