The Gruyere Gold Project was discovered by Gold Road Resources Limited in October 2013 on the Yamarna Belt, 200 km east of Laverton in Western Australia. As a low-grade mineral resource, the feasibility study for Gruyere, completed in October 2016, culminated in the selection of a primary crush semi-autogenous grinding (SAG)-ball circuit with recycle pebble crushing (SABC). An engineering, procurement, and construction (EPC) contract was executed in June 2017, with construction commencing in early 2018 and commissioning of the SABC circuit commencing in early 2019. Since 2019, the Gruyere Joint Venture (Gruyere JV), a collaboration between Gold Road Resources Ltd and Gold Fields Ltd, has been dedicated to the ramp-up and operations phases of the project. Operational ergonomics, advanced process control, throughput optimisation, mechanical availability, and metallurgical recovery consistency have all seen substantial improvements. In 2023, Gruyere JV successfully processed 9.4 Mt/a of ore, produced 320 000 gold ounces, and extended the mine’s life through the open pit expansion project. This paper investigates the continuous test work, subsequent modelling, and improvement projects carried out during the ramp-up and early operational phases, including:  Implementing mechanical enhancement projects and modifications to the original design to alleviate wear and availability concerns.  Conducting ongoing comminution studies and benchmarking surveys of the grinding circuit.  Fine-tuning SAG and ball mill liner designs, optimising grinding media, and refining post-reline ramp-up strategies.  Enhancing the pebble crushing circuit’s capacity through a series of circuit and equipment upgrades.
