Ark Mines is pleased to confirm that a panned concentrate assay produced last week at the Company’s 100%-owned Sandy Mitchell rare earths and heavy minerals project in North Queensland has returned exceptionally high grades as highlighted above.
Announcement highlights:
- A single panned concentrate sample using XRF technology returns 29% TREO; significantly exceeds historical grades first reported in late March 2023 and importantly validates historical sampling.
- High levels of neodymium praseodymium (NdPr) with NdPr ratio recorded of up to 24% of Total Rare Earth Oxides (TREO)
- Heavy Minerals also present in sample including 11.2% Titanium dioxide (TiO2) and 17% Zirconium dioxide (ZrO2)
- Sample was taken from surface sand at Sandy Mitchell, within the area where Ark is presently drilling, has confirmed high grade rare earths and heavy metals in a pan concentrate
- Pan concentrate samples have been collected from every completed metre drilled; rare earth elements and heavy minerals are visually evident in all samples from first 1,000m of drilling

The Executive Chairman of Ark Mines was excited to announce the news, and what this entailed;
“These results are highly encouraging, with this sample delivering exceptionally high-grade rare earths and a high NdPr ratio. The pan concentrate sample improves on the results that we have identified from the historical data which gives us much greater confidence in the project. We are sampling every metre that we drill and, while the XRF result is pleasing, more extensive and multiple assays are planned.”

Executive Chairman
