Red Mountain is preparing to kick off drilling for rare earth elements at its Mt Mansbridge project in Western Australia after completing a key heritage survey.

The heritage survey with members of the Tjurubalan traditional owners has opened up access to several prospects, allowing the company to start earthworks ahead of drill operations that are scheduled to begin in mid-October.

Red Mountain Mining’s (ASX:RMX) drilling will test the Mansbridge xenotime-dysprosium occurrence within the Killi-Killi formation and the Kylo xenotime-dysprosium occurrence within the same formation.

Discussions are ongoing with the Tjurubalan in relation to providing access to the Killi-Killi unconformity feature during the 2022 exploration season.

Rare earths targets

The Mansbridge prospect was first identified by BHP during uranium exploration in the 1980s and consists of a +200m long zone of mineralisation associated with veining and alteration within the Killi-Killi basement with recent mapping and rock chipping validating the geology of the prospect and the historical rock chips collected by previous explorers.

Red Mountain plans to drill four reverse circulation holes to test the REE mineralisation.

Kylo is one of the two prospects within the project area with observed xenotime mineralisation.

Assaying returned elevated yttrium and dysprosium values from a ‘siliceous cherty’ unit proximal to the unconformity.

One hole is planned to be drilled into this unit.

Other targets

The company is planning to drill three holes to test the Déjà vu nickel-copper-cobalt-PGE prospect that was identified and drilled by CRA between 1991 and 1993.

These holes will provide further geological information, intersect the prospective contacts and provide a comprehensive set of samples around the existing cobalt anomaly.

A number of prioritised holes will also test the Cow Creek nickel-copper-cobalt-PGE prospect, which consists of several regionally distinctive, generally north-northwest trending, elongated, magnetic features.

This area has been interpreted as a mafic-ultramafic intrusive complex, similar to what hosts the Sally Malay/Savannah Nickel Deposit.
