Moho Resources Ltd (ASX:MOH) has confirmed the presence of thick, high-grade clay hosted rare earth elements (REEs) at its Peak Charles Project in Western Australia.
The results come from the company’s second round of reconnaissance aircore drilling at the project, situated north of Esperance.
Notably, 81% of all 43 phase 2 aircore drill holes returned assays greater than 300ppm TREO and 35% returned assays greater than 750ppm TREO.
The best two-metre composite sample was in drill hole PPAC095, delivering 56-58 metres at 2118ppm TREO at the Top Block Prospect.
The presence of green muscovite and elevated TREO levels at the base indicates hydrothermally altered granite is the source of REE mineralisation at Top Block.
“Fantastic outcome”
Moho managing director Ralph Winter said: "The second phase of outstanding total rare earth results from Peak Charles with large thicknesses of clay-hosted rare earth mineralisation over 1.4 kilometres is a fantastic outcome for the company’s critical minerals strategy.
“With positive landholder relationships being cultivated the company is perfectly situated to take advantage of the burgeoning clay-hosted rare earth province near Esperance and now has multiple targets to expand across the project.”
Drill program
The objective of the phase 2 drill program was to test the continuation of the clay basin hosted rare earth elements mineralisation which had been identified between three different prospects during the first phase of drilling.
The second phase 43-hole reconnaissance and infill aircore drill program at E74/695 were designed to further understand the geological constraints of the project area.
In addition, drilling will also test for the continuation of the clay-hosted REE mineralisation defined during the first phase of aircore drilling.

Results summary
Moho delivered strong total rare earth oxides (TREO) results at Top Block prospect with large thicknesses of high-grade clay-hosted mineralisation, including:
- 56 metres at 1,023ppm TREO from 24 metres including 18 metres at 1,470ppm TREO;
- 40 metres at 689ppm TREO from 30 metres including 6 metres at 1,057ppm TREO;
- 21 metres at 1,056ppm TREO from 24 metres including 8 metres at 1,528ppm TREO; and
- 18 metres at 971ppm TREO from 20 metres including 6 metres at 1,185ppm TREO.
Drilling to date shows Top Block prospect extending at least 1.4 kilometres.
The presence of green muscovite and elevated TREO levels at the base indicates hydrothermally altered granite is the source of rare earth mineralisation at Top Block.
Forward plan
The next steps at Peak Charles include:
- passive seismic survey over the Top Block prospect to define the extent of the Top Block clay basin;
- complete aircore drilling at Rollond East prospect and road reserve access drilling around the Gimli prospect;
- land access agreements with landholders of Top Block prospect;
- POW applications for Top Block aircore drilling on crown land and land of the State of Western Australia west and east of the highly prospective Top Block drill line; and
- soil sampling of the Rad 2 anomaly after harvesting of the current wheat crop.
