The 1,200m RC drilling program – due to kick off later this week — will test several rare earth element (REE), cobalt and nickel-copper-cobalt-PGE targets at the flagship Mt Mansbridge project in WA.

An RC drilling contractor has been secured and is set to commence once earthworks have been completed, Red Mountain (ASX:RMX) says.

The upcoming drill program will test several REE targets, finalised during the recently completed mapping and rock chipping program and from various studies and data acquisition programs by RMX over the past year.

They include the ‘Mansbridge Xenotime-Dysprosium Occurrence’, which was first identified during uranium exploration by BHP. Heavy rare earths mineralisation has been confirmed by recent rock chipping.

The ‘Kylo Xenotime-Dysprosium Occurrence’ – a historical rock chip collected by Northern Minerals which coincides with an anomaly – and the large ‘Killi-Killi Unconformity Feature’ will also be drilled.

Nickel-Copper-PGE targets

The ‘Déjà vu’ nickel-copper-PGE prospect was identified and drilled by CRA between 1991 and 1993. The prospect was unsuccessfully targeted for diamond bearing kimberlites, but sporadic sampling and assaying through the ultramafic intrusive unit returned several encouraging cobalt assay results between 70-100m including 0.34%, 0.32% and 0.22%.

A traverse of three RC holes is planned to be drilled across the intrusion, RMX says.

The ‘Cow Creek’ prospect consists of several regionally distinctive, generally north-north-west trending, elongated, magnetic features within a broader ovoid area measuring 7x7km.

The area has been interpreted as a mafic-ultramafic intrusive complex, like what hosts the Sally Malay/Savannah Nickel Deposit owned by Panoramic Resources.

This regionally significant geophysical anomaly has never received any effective exploration activity.

A number of prioritised holes have been planned to test the features during the upcoming program.
