Epiroc has secured a large underground mining equipment order from MMG Limited for the Khoemacau copper mine in Botswana, where MMG is working with Chinese contractors China Huaye and 23MCC under the ownership of China Minmetals Corp. The package is expected to include core underground production fleets such as face drilling rigs, loaders and mine trucks suited to deep, high-tonnage copper operations. For engineers, the deal signals long-term mechanised development at Khoemacau and likely standardisation around Epiroc’s automation-ready platforms and digital support tools.

GR Engineering Services has signed an EPC contract with Myamba Minerals, a Medallion Metals subsidiary, to redesign, procure, construct and commission the conversion of the existing Cosmic Boy Concentrator in Western Australia. The brownfield plant, originally built for nickel, will be reconfigured for Myamba’s processing requirements, allowing reuse of major infrastructure rather than building a new concentrator. For project engineers, the deal signals upcoming detailed process design, tie-ins to existing utilities and structural upgrades around the grinding, flotation and tailings handling circuits.

Crushing, conveying and screening circuits are identified as major sources of avoidable downtime in fixed plant, with bearing, gearbox and drive failures often traceable to misalignment, poor lubrication and contamination rather than design limits. A Motion–Timken webinar uses real-world case studies on crushers, screens and overland conveyors to show how condition monitoring, correct bearing selection and improved sealing can extend component life and reduce unplanned stoppages. Reliability engineers and maintenance planners are urged to focus on root-cause failure analysis and data-driven inspection intervals rather than reactive part replacement.
