    MMD Sizers for Butcherbird Expansion: throughput and circuit notes for plant engineers

    First reported on International Mining – News

    30 Second Briefing

    MMD Australia (West) Pty Ltd has secured a contract to supply an MMD 625 Primary Sizer and an MMD 500 Secondary Sizer to Element 25’s Butcherbird Expansion (BBX) project in the Pilbara, Western Australia. The sizers will be integrated into the Butcherbird Manganese Mine’s upgraded processing circuit to handle higher throughputs as Element 25 ramps up manganese output. For plant and materials engineers, the move signals a shift towards higher-capacity in-pit or plant-based sizing solutions tailored to Pilbara ore characteristics and remote operations.

    Technical Brief

    • Contract scope covers both primary and secondary sizing stages within Element 25’s BBX process upgrade.

    Our Take

    Manganese appears in only a handful of pieces in our database compared with iron ore and lithium in Western Australia, so the Butcherbird Manganese Mine expansion signals one of the relatively few Pilbara projects diversifying away from the dominant bulk commodities.

    Use of MMD 625 and 500 Sizers at the Butcherbird Expansion (BBX) project suggests Element 25 is designing the plant around compact, low-height crushing units, which can simplify layout and civils on flat Pilbara sites compared with conventional cone or jaw-crusher trains.

    For Pilbara operators, MMD Australia (West) Pty Ltd’s role here underlines that specialist sizer vendors are still winning greenfield and expansion work, which may influence tender strategies for other manganese and battery-metal projects looking to handle sticky or variable ores.

    Suncor Cat AHS at Mildred Lake and Komatsu Mud Mode: integration notes for mine planners

    Suncor has commissioned its first Autonomous Operating Zone at Syncrude’s Mildred Lake oil sands mine, extending its autonomous haulage system deployment beyond the existing fleet of about 140 autonomous trucks already running at other Suncor sites. The new zone uses Cat AHS fleets under Suncor control (since late 2021) and is complemented by Komatsu AHS trucks at Base Plant operating with a dedicated “Mud Mode” to maintain traction and control in soft ground. For mine planners, this signals wider-scale AHS integration across multiple pits and variable ground conditions.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.
