One of Australia’s largest underdeveloped gold deposits, the Gruyere Gold Project a significant gold deposit.  The mineral resource has been defined as 148 million tonnes, grading 1.2 grams per tonne for 6.2 million ounces of contained gold.

The Gruyere Gold Project was discovered by Gold Road in October 2013 on the South Dorothy Hills Trend, which is 25kms north east of the Yamarna Belt discovery, Central Bore.

It is located about 200km east of Laverton, Western Australia.

In 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 WA.

Mining Operations

Set to become of the nation’s deepest open cut gold mines, mining operations at Gruyere currently consist of one main open pit that will be developed in stages to an approximate depth of 500 metres below the surface.

All mining activities including loading, hauling, drilling, blasting and equipment maintenance is carried out by a mining contracting company using large scale mining equipment.

The mine’s current life span has been extended to 2031, which includes Golden Highway satellite pits which are situated about 30km from the main Gruyere mine.

The first gold pour took place in July 2019, and it is estimated Gruyere will 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.
