Western Mines Group (ASX:WMG) entered into a memorandum of understanding (MOU) with Magnium Australia to collaborate on the potential supply of magnesite from the Mulga Tank project in Western Australia, according to a Thursday filing with the Australian bourse.

The company will define the extent of the magnesite cap at the project and provide samples to Magnium Australia for test work, with the two parties aiming to negotiate a formal supply agreement at a later date, the filing said.
