    GR Engineering’s 3 Mt/y Davyhurst plant: design and throughput notes for mine teams

    GR Engineering’s 3 Mt/y Davyhurst plant: design and throughput notes for mine teams

    First reported on International Mining – News

    30 Second Briefing

    GR Engineering Services has been named preferred EPC contractor by Ora Banda Mining to deliver a 3 Mt/y gold process plant for the Davyhurst Expansion Project in Western Australia. The appointment follows Ora Banda’s ASX update outlining a step-up from the current 1.2 Mt/y Davyhurst plant, signalling a major throughput increase across its existing open pits and underground resources. For plant designers and contractors, the project points to upcoming demand for larger comminution, leach and tailings handling circuits in the Eastern Goldfields.

    Technical Brief

    • Appointment as “preferred contractor” indicates commercial terms still subject to final contract execution.
    • Contract structure implies GR Engineering will manage procurement risk and construction interface with existing site.

    Our Take

    A 3 Mt/y plant in Western Australia places the Davyhurst Expansion Project at the mid-scale end of gold-style processing capacity in our mining database, which typically supports flexible sequencing of multiple satellite pits or underground sources rather than a single large orebody.

    GR Engineering Services Limited appears frequently in our Australian project coverage as an EPC contractor on similar-sized plants, suggesting Ora Banda Mining Limited is following a de-risking pattern of using an experienced brownfields contractor for schedule and cost control.

    FireFly’s Green Bay project economics: NPV, IRR and capex lens for mine planners

    FireFly Metals’ Green Bay copper-gold project in Newfoundland now carries an after-tax NPV of A$2.2 billion (C$2.1 billion) at a 7% discount rate and a 42% IRR, with initial capital of A$513 million, giving more than four times NPV-to-capex leverage and planned throughput of 1.8 million tonnes per year over 32 years. Updated measured and indicated resources stand at 60.2 million tonnes grading 1.9% Cu, 0.5 g/t Au and 4.2 g/t Ag, containing 1.1 million tonnes Cu, 908,000 oz Au and 8.1 million oz Ag after 69,539 metres of underground drilling. A feasibility study is targeted for Q1 2027, with a final investment decision in H2 2027 and first concentrate potentially in mid-2029, backed by a proposed A$180 million equity raise split between an ASX institutional placement and a Canadian bought deal.

    Waratah’s new shallow high-grade Consols gold zone: pit design notes for planners

    Waratah Minerals has extended the Consols gold system at its Spur project in New South Wales by 75m to the east and down-plunge, while identifying a new shallow high-grade zone. Step-out hole SPD074 intersected 12.7m at 1.35g/t gold from 44m downhole, defining a near-surface target with open extensions. For mine planners and geotechnical teams, the shallow geometry and incremental strike extension suggest potential for low-strip open-pit designs and simplified access for infill drilling and geotechnical characterisation.
