Gold Fields and Gold Road launch Gruyere ramp-up

Gruyere joint venture partners Gold Fields and Gold Road Resources have begun ramping up development at the Gruyere gold mine in Western Australia.

Gold Road and member of Gold Fields, Gruyere Mining has completed the commissioning of the final components of the process plant, in particular, the ball mill and gravity circuit.

Gold Road reported that several minor improvements to the operability of the circuit were made during a plant shutdown for the tie-in of the ball mill. All components of the process circuit are now substantially complete and operational.

The announcement follows minor setbacks faced at the site as the joint venture partners were unable to commission the ball mill within the contractual completion dates earlier this year.

Consequently, production guidance for the year was lowered to between 75,000 and 100,000 ounces, down from 100,000 and 120,000 ounces previously.

This also resulted in the operation’s all-in sustaining costs (AISC) being higher than the previous guidance of between $1050 and $1150 an ounce and will be reviewed when commercial production is declared.

The JV partners expect commercial production to occur mid-way through the six to seven-month ramp up period as was previously indicated.

The news of Gruyere’s ramp-up comes as Gold Fields and Gold Road delivered first gold at the site at the start of July, with three dore gold bars totaling 1139 ounces being produced from the carbon-in-leach and elution circuits.

Gruyere, which is located approximately 200 kilometres east of Laverton in Western Australia, is a global Tier 1 gold mine with a long operating life and forecast high margins. Read more…
