- Mastermyne Group Limited is an Australia-based mining services company specializing in underground coal mining contracting, mine operations, and comprehensive mine support services. Its core products and services include new mine development, mine operation, roadway development, conveyors, outbye services, ventilation, secondary support, longwall relocations, polymeric emergency strata consolidation, production and ancillary equipment services, and mining consumables. The company operates under the Mastermyne, Wilson Mining, and MyneSight brand names, with Wilson Mining focusing on strata control products and MyneSight providing registration training and compliance solutions for the mining industry. Founded in 1996 and headquartered in Mackay, Queensland, Mastermyne serves major coal mining clients across Australia including Anglo American, South 32, BMA, Glencore, Rio Tinto, Whitehaven, and Peabody.
Recently, Mastermyne Group Limited officially reverted from the name Metarock Group Limited back to Mastermyne Group Limited in November 2024 to align with its strategic refocus on core business operations. The company secured significant contract extensions and new agreements in 2025, including a six-month extension with Anglo American Metallurgical Coal valued at approximately A$31 million and a three-year agreement with Yancoal Australia estimated between A$15 and A$20 million for outbye, ventilation, and strata consolidation services. Additionally, Mastermyne expanded its mining services footprint by executing a contract mining agreement at the Appin coal mine in New South Wales, anticipating revenues of around A$180 million over three years. These developments underscore its strategic positioning as a key underground coal mining contractor across the Australian mining industry landscape.
