Explorer Red Mountain Mining has kicked off a 1,200m RC drilling program at its Mt Mansbridge Project in the Eastern Kimberley of Western Australia. 

The program will test several targets at the project under the supervision by members of the Tjurubalan, the Traditional Owners of the land.

The targets include:

  • Mansbridge xenotime-dysprosium occurrence – located within the Killi-Killi formation within quartz veining and alteration identified during uranium exploration by BHP (ASX:BHP). HREE mineralisation confirmed by recent rock chipping; and
  • Kylo xenotime-dysprosium occurrence – a historical rock chip collected by Northern Minerals Ltd. within the Killi-Killi formation. The rock chip coincides with the T4 radiometric anomaly.

Red Mountain (ASX:RMX) expects the drilling to take 14 days to complete with assay results to follow.

Déjà vu cobalt prospect potential

The Déjà vu Prospect was historically drilled for diamond bearing kimberlites, and sporadic sampling and assaying by the company has returned several encouraging cobalt assay results between 70-100m including 0.34%, 0.32% and 0.22% cobalt.

Litho-geochemical studies have also highlighted the cobalt as primary magmatic related (i.e. not weathering enrichment) and that the anomalous cobalt values can’t be explained by the observed silicate minerals within the peridotite only.

Red Mountain plans to drill a traverse of three RC holes across the intrusion to intersect the prospective contacts and provide a comprehensive set of samples around the existing cobalt anomaly.

Cow Creek nickel-copper-cobalt-PGE prospect

The Cow Creek prospect consists of several regionally distinctive, generally north-northwest trending, elongated, magnetic features which sit within a broader ovoid area measuring 7x7km – an area ringed by further less intensive magnetic anomalies.

The company interprets the area as a mafic-ultramafic intrusive complex, similar to that which hosts Panoramic Resources’ (ASX:PAN) Sally Malay/Savannah nickel deposit.

The company plans to complete two drill holes at the prospect to test the magnetic features identified during a recent inversion of the magnetic data.
