Mt Grace Batchelor Magnesium

Mt Grace Resources NL has submitted a Notice of Intent with the Department of Lands Planning and Environment, detailing a proposal to construct a Magnesium Mine and Smelter on Mineral Lease Number 1984, 300m south of the Batchelor – Stuart Highway road, 4km east of the Batchelor Township

The mine will be open cut, the depth of which will be dependent on the economic viability of the ore. Currently a 30-year life has been proposed, but as the ore body is open at depth, this could extend further. Ore will be extracted on a campaign basis with stockpiling of several years’ supply from a single campaign dry season.

The milling process will consist of a crushing, grinding and flotation circuit feeding into a rotary kiln and then further into a ‘Heggie’ furnace involving an electric plasma arc. From this magnesium metal and a substance similar to garnet is produced. The milling process is energy intensive and will require approximately 70 kW of power during peak operation. It is intended that this power will be sourced from the Darwin grid.

Magnesium metal ingots will be shipped out of Darwin. Transport to Darwin will be via Road Train. The project is located 4 km to the west of Batchelor along the Batchelor-Stuart Hwy road.
