Rosebery is approximately 300 kilometres north-west of Hobart and 125 kilometres south of Burnie. Rosebery is 100% owned by MMG Limited and has been operating continually for over 80 years, with operations starting in 1936.
Zinc, copper and lead concentrates, as well as gold doré, are produced at Rosebery using mechanised underground mining method followed by crushing, grinding and floatation processes.
Concentrates are then transported by rail to the Port of Burnie where they are shipped in bulk carriers to smelters in Hobart and Port Pirie. Gold doré bars are sold to a refinery in Australia where they refined into gold bullion.
Annual production at Rosebery is expected to be around 55,000 – 65,000 tonnes of zinc in zinc concentrate. The operation continues to deliver excellent operational performance that saw 2018 deliver record levels for mining, milling, zinc equivalent production and payable metal in product sold.
More information about our ore reserves can be found in our Mineral Resources and Ore Reserves report, and in our Quarterly Production Reports.
The operation employs around 430 employees and contractors on a local residential basis. Over 97.94% of the employees on site are Australian nationals.
The future of Rosebery
We are celebrating 85 years of continuous operation at Rosebery Mine this year and MMG is proud to be a part of this tremendous history. In recent years, we have invested significantly in exploration, and are pleased to have identified the underground ore bodies that will continue Rosebery’s legacy for the benefit of a new generation of Tasmanians.
Exciting times lie ahead for the mine, Rosebery township and approximately 500 employees and contractors, as it means an extended life of mine, regional jobs, and continued economic contribution. We are working closely with Government agencies through the planning and permit application process to extend the supporting facilities the mine requires. As we move forward, we will always ensure we are compliant with all required regulations throughout the design, construction, and maintenance process of our operations now and into the future.
