During 2020, Sojitz appointed Mastermyne to undertake a feasibility study focusing on the development of a high productivity bord and pillar mining operation. In parallel, Mastermyne were also engaged as the Mine Operator to undertake the re-entry process. The underground mining area was successfully re-entered in late October 2020, with no issues encountered. Mastermyne has continued as the Mine Operator whilst Sojitz finalised internal approvals.
Following the re-establishment works, the mine immediately transition into production with a staged ramp up to 3 bord and pillar mining units. The underground mine will produce approximately 11 million tonnes ROM (run of mine) over the life of the project.
Mastermyne will provide underground mining equipment from its current fleet, including 3 bord & pillar miners, multi bolters and shuttle cars along with a range of ancillary production equipment to ........
