    Metso–Emerald grinding mills: design envelopes and throughput notes for engineers

    Metso–Emerald grinding mills: design envelopes and throughput notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    Metso has secured orders worth over €10 million to supply two horizontal grinding mills to Emerald Resources NL for the Dingo Range gold project in Western Australia and the Memot gold project in Cambodia, with booking recorded in the Minerals segment’s June 2026 quarter. The twin-mill package signals parallel process plant build-outs across two jurisdictions, giving Emerald commonality in comminution equipment, spares and control philosophy. For project engineers, early mill selection fixes key design envelopes for foundations, power demand and downstream throughput at both greenfield sites.

    Technical Brief

    • Parallel supply to Western Australia and Cambodia introduces logistics and customs scheduling risk across two jurisdictions.
    • Common OEM for both mills simplifies spares inventory, tooling and liner/parts interchangeability across the fleet.
    • Early OEM engagement allows foundations, power reticulation and structural steelwork to be detailed around confirmed mill footprints.
    • Similar dual-jurisdiction mill packages are increasingly used to standardise control logic and operator training across portfolios.

    Our Take

    Metso’s orders for the Dingo Range and Memot gold projects align with a run of recent coverage showing the company pushing deeper into gold hubs on multiple continents, including its new local capabilities in San Juan, Argentina (copper/gold) and a bulk handling hub in Cape Town.

    Across the 383 gold-tagged pieces in our database, relatively few involve Cambodia, so the Memot gold project order signals that Metso is extending its processing footprint into less-established gold jurisdictions compared with its more common Australian and Latin American deployments.

    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.
