• Two new TREO soil and radiometric anomalies have been identified
  • The Peak Charles project sits within emerging Esperance rare earths province
  • Geochemistry survey and aircore drilling planned


Moho Resources has identified two coincident Total Rare Earth Oxide (TREO) soil and radiometric anomalies within a 50km-long trend at its Peak Charles project in Western Australia, significantly enhancing the project’s rare earths prospectivity.

Peak Charles is an 874km2 contiguous tenement package near Esperance, an emerging rare earths hotspot.

The project adjoins OD6 Metals (ASX:OD6) Grass Patch tenements, where high-grade clay rare earths were reported during regional reconnaissance drilling earlier this year.

Although the original target commodities for the project were nickel-copper sulphide and gold, Peak Charles has now shown large-scale potential for clay basin hosted rare earth mineralisation.

“Moho is very encouraged by the identification of the coincident rare earth soils and radiometric anomalies within a 50km magnetic trend,” Moho Resources (ASX:MOH) MD Ralph Winter said.

“It is a significant development for Moho’s critical minerals advancement in the burgeoning Esperance rare earth province and lays a solid foundation for the company’s value creation in the market.”


50km of potential rare earth-enriched intrusions

A data review of assay results from soil sampling surveys has shown a progressive increase in soil TREO levels towards the core of a Gimli radiometric anomaly, rising from background values below 100ppm TREO to maximum of 620ppm TREO at the centre of the anomaly.

A similar soil geochemical trend is also apparent over a second radiometric anomaly at the Pippin anomaly, about 15km SSW of Gimli, with levels rising to a maximum of 583ppm TREO at the centre of the anomaly.

Moho management says anomalous TREO levels in soil over both Gimli and Pippin anomalies may indicate the presence of rare earth-enriched intrusions.

“The Gimli and Pippin anomalies are part of a linear cluster of 4 radiometric anomalies within a distinct, structurally complex 50km long magnetic domain trending SSW-NNE that could have been the conduit for the emplacement of such proposed intrusions,” Moho said.


Aircore drilling planned

Moho will now undertake a geochemistry survey of 750 soil samples at 100x100m spacing to follow up in full on the four radiometric anomalies from the orientation soil sample survey.

Preliminary aircore drilling program will also be conducted to define the bedrock lithologies and associated REE anomalism following review of assay results of soil survey and access agreements at Gimli and Pippen prospects.

Assay results are also pending from a follow-up aircore drilling program completed in July at the E 74/695 tenement at Peak Charles.

Moho also plans to review and report metallurgical test work to determine REE extraction rates from the clays along with further geophysical interpretation of the airborne magnetics to outline granite basement topography required for ionic clay target modelling.
