Mamba Exploration (ASX:M24) has started a 50-hole aircore/RC drill program at the Hyden REE Project, where historical exploration revealed anomalous phosphorus and REE mineralisation.

The Western Australian focused gold, nickel, and copper explorer says the drilling will serve as an initial test of the gravity target.

Mamba Exploration also says additionally, assay results for 23 aircore drillholes completed in January at the clay-hosted TREO target are being compiled, with a release planned for early next week.
