Mamba Exploration (ASX:M24) has agreed on a six-month extension of the REE (rare earth elements) option over the Hyden Project and has extended the term for the key exploration license for an additional five years until January 30, 2028.

The extension allows Mamba to conduct further investigation on the project, including analysing drill results and completing metallurgical tests on identified regolith-hosted REE mineralisation.

Assays are expected for 58 shallow drill holes in May.
