Mastermyne Group has secured a new mining services contract with GMT Mining Pty Ltd for the restart and ongoing operation of the Tahmoor underground coal mine in New South Wales. The mine was recently acquired by a consortium of M Group – Mastermyne’s largest shareholder – and Golden Energy and Resources (GEAR), and will be operated by GM3. The deal signals a structured restart pathway for Tahmoor, with clear separation between ownership (M Group/GEAR), operations (GM3) and contracted underground services (Mastermyne).

FLSmidth has secured a major order in Chile to supply core grinding technologies for a new copper grinding line, including high-pressure grinding rolls (HPGR) and a ball mill. The package follows earlier collaborative engineering work on the mine’s expansion and is positioned as the next phase of a long-term process plant partnership with the unnamed customer. For process engineers, the HPGR–ball mill configuration signals continued confidence in energy-efficient comminution flowsheets for large-scale copper operations in the Andean region.

Superior Industries is making its patented Titanium Seal standard on all conveyor idlers, shifting it from a premium option to baseline specification across its bulk material handling range. The seal is engineered to protect idler bearings from contamination and extend service life by at least 25% compared with conventional designs, directly targeting failures from dust and moisture ingress on overland and plant conveyors. For mine operators, the change signals longer idler replacement intervals, reduced unplanned stoppages and potentially lower spares inventories on high-tonnage conveyor systems.
