Macro Metals (ASX:M4M) acquired an 80% interest in the DSO manganese assets in Western Australia from Firebird Metals (ASX:FRB), according to a Tuesday filing with the Australian bourse.

The companies agreed to remove the Midgengadge project from the acquired tenement package and will only acquire 80% of the Wandanya and Disraeli projects, the filing stated.

The amended agreement requires a minimum expenditure of AU$112,500 across the two projects and at least 10 reverse circulation drill holes for no less than 100 meters drilled on each project.
