    GR Engineering’s Northparkes CPF EPC: integration and retrofit notes for process engineers

    April 9, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    GR Engineering has secured an EPC contract from Northparkes Mining Services, a subsidiary of Evolution Mining, to deliver a Coarse Particle Flotation (CPF) project at the Northparkes copper-gold operation, 300 km west of Sydney, New South Wales. The project will retrofit CPF into the existing concentrator, targeting recovery of coarser sulphide particles that currently bypass conventional flotation circuits. For process engineers, the key change is integration of new CPF cells and associated regrind, pumping and classification modifications into a brownfield plant while maintaining throughput.

    Technical Brief

    • Brownfield CPF retrofits of this type are increasingly being adopted at Australian copper concentrators to lift recovery.

    Our Take

    GR Engineering’s selection at Northparkes in New South Wales follows its recent EPC roles on the Tower Hill and Laverton gold projects in Western Australia, signalling that operators are favouring the company for brownfield processing upgrades and modular plant work across multiple states.

    With Northparkes located about 300 km west of Sydney, the project sits in a well‑serviced but increasingly competitive NSW mining corridor, where established logistics and power links can materially reduce schedule and cost risk for complex flowsheet retrofits like coarse particle flotation.

    Our database shows GR Engineering appearing frequently in recent Mining ‘Projects’ and ‘Contract Award’ coverage, suggesting that mid‑tier operators such as Evolution Mining are leaning on specialist EPCs rather than in‑house project teams for debottlenecking and recovery‑improvement projects.

    Cementation Africa–Tharisa underground shift: design and cost notes for mine engineers

    Tharisa Minerals has fired the inaugural underground blast at its Bushveld Complex chrome and PGM operation, initiating the transition from open pit to underground mining scheduled from 31 March 2026. Cementation Africa, the contracting partner, will be central to developing the new underground infrastructure, including access declines and associated services, to extend mine life and access deeper ore. The shift will alter geotechnical design demands, ventilation and ground support requirements, and could change the mine’s stripping ratio and cost profile over the medium term.

    Saturn’s Apollo Hill and Ausenco study: design and pit optimisation notes for engineers

    Saturn Metals has reported new high-grade gold intercepts at its Apollo Hill project in Western Australia and appointed Ausenco to complete a scoping study for a standalone gold operation. The work will assess processing options for the large, low-grade Apollo Hill resource using Ausenco’s gold plant design expertise, including trade-offs around throughput, recoveries and capital intensity. For mine planners and geotechs, the study outcome will shape pit shell optimisation, cut-off grade strategy and geotechnical design parameters for a potential new open pit development in the Eastern Goldfields.

    Wildcat’s Bolt Cutter lithium system: scale, pit shells and drilling notes for engineers

    Wildcat Resources has extended the Bolt Cutter Central lithium system in the Pilbara, with new reverse circulation and diamond drilling stepping out from the discovery holes to grow the mineralised footprint. Recent holes have intersected additional spodumene-bearing pegmatites at shallow depths, confirming continuity of the lithium-bearing corridor along strike and down dip. The results point to a larger-scale hard-rock lithium target, with implications for future resource definition drilling, pit shell optimisation and potential integration with regional Pilbara lithium infrastructure.
