    MMG’s Khoemacau copper mine expansion: design and throughput notes for planners

    First reported on International Mining – News

    30 Second Briefing

    MMG’s board has approved the feasibility study and committed to construction of a major expansion at the Khoemacau Copper Mine in Botswana, targeting annual output of 130,000 t of copper in concentrate. The project will also lift associated silver production above current levels, positioning the operation as a large-scale polymetallic producer in the Kalahari Copper Belt. For mine planners and process engineers, the step-up in concentrate tonnage will drive requirements for upgraded underground development, hoisting, and concentrator throughput, as well as expanded tailings and water management infrastructure.

    Technical Brief

    • Board-level approval of the feasibility study moves the Khoemacau expansion into funded construction execution.
    • Commitment to construction implies near-term mobilisation of underground development contractors and process plant upgrade teams.
    • Expansion scope will require reconfiguration of mine scheduling, haulage profiles and backfill or waste handling strategies.
    • Process plant changes are expected to include higher milling throughput and upgraded flotation, thickening and filtration capacity.
    • Tailings storage and water supply systems will need staged capacity increases to match the higher concentrate output.
    • Power demand at Khoemacau will rise, driving grid connection upgrades or additional on-site generation and distribution.

    Our Take

    Copper items make up a significant slice of the 462 Mining stories in our database, but Botswana features far less frequently than jurisdictions like Chile or the DRC, so an MMG Ltd expansion at Khoemacau signals growing weight for southern African copper in project pipelines.

    Among the 883 tag-matched ‘Projects’ and ‘Contract Award’ pieces, copper–silver combinations like Khoemacau tend to be associated with underground or deeper orebodies, which usually implies higher upfront development complexity but more stable long‑term grade profiles once established.

    MMG Ltd appears in far fewer of our recent copper project items than some of the largest diversified miners, so committing to expansion in Botswana likely reflects a deliberate move to rebalance its portfolio towards long‑life base metals outside its traditional strongholds.

    Scope Systems cyber attack: resilience and risk lessons for mining IT teams

    A ransomware attack on Perth-based Scope Systems’ Pronto Xi ERP cloud stack disrupted dozens of mining customers, including Northern Star Resources and Evolution Mining, in what MM‑ISAC’s Rob Labbe calls the broadest single third‑party cyber event the sector has seen. Scope says client servers were restored from backups and not directly accessed, but admits internal data was exfiltrated and has not disclosed the attack vector, raising questions about visibility at hypervisor, storage and backup layers. The incident spotlights how multi‑tenant vCenter/ESXi environments, VM cloning and snapshot abuse—already used by groups like Akira—could expose integrated exploration, production and maintenance data across more than 400 Pronto Xi‑reliant mining operations.

    Newmont’s Red Chris underground expansion: block cave design and capex notes for engineers

    Newmont’s Red Chris mine in British Columbia has secured an amended Environmental Assessment Certificate and Mines Act permit, allowing a shift from open-pit to underground block caving and extending operations into the mid-2040s. The copper-gold porphyry deposit in the Golden Triangle hosts an estimated 20 million oz of gold and 13 billion lb of copper, with the block cave expected to lift Canada’s copper output by about 15%. The project entails several billion dollars in capital, around 1,800 construction jobs and roughly 1,500 operating roles at peak.

    Goldman cuts gold price forecast to US$4,900: planning notes for mine projects

    Goldman Sachs has cut its end‑2026 gold price forecast by US$500/oz to US$4,900/oz after the US Federal Reserve, under new chair Kevin Warsh, signalled a hawkish shift that has pushed market-implied December rate hike odds to 87%. Spot gold has already fallen to about US$4,100/oz, down 27% from its near‑US$5,600/oz January peak, with three consecutive monthly losses between March and May and a 4% year‑to‑date decline. Goldman warns a 2026 year‑end target as low as US$4,400/oz is possible if rates rise, partly offset by ongoing central‑bank buying of roughly 50 tonnes/month this year and 40 tonnes/month next year.
