- Red Mountain Mining (RMX) has updated the market on the size by size assay and x-ray diffraction results from its channel sampling at the Murray pit in the Mt Kokeby Kaolin Project
- A total of nine samples were taken from five locations within the old pit area
- The results confirmed outstanding yields- each at an average grade above 36 per cent of aluminium oxide

Red Mountain Mining (RMX) has provided size by size assay and x-ray diffraction (XRD) results from its channel sampling at the Murray pit within the Mt Kokeby Kaolin Project.
A total of nine samples were taken from five locations within the old pit area.
In November, the company reported raw in-situ results, which revealed a maximum alumina grade of 37 per cent, with seven of the nine samples having greater than 35 per cent alumina.
A laboratory size by size particle analysis was undertaken, where the kaolin samples were passed through the mesh of different sizes to determine the amount of Alumina retention for each mesh.
The results confirmed outstanding yields of over 83 per cent for -38 micrometer and over 85 per cent for -75 micrometre – each at an average grade above 36 per cent of aluminium oxide.
“The high yields and low recovery loss from a simple beneficiation process, together with the mineral characteristics of the samples, augurs well for a low cost
DSO kaolin operation at Mt Kokeby,” Company Director Jeremy King said.
“We look forward to conducting the due diligence drilling programme in the near term,” he added.
The metallurgical test work program is currently being undertaken and managed by Independent Metallurgical Operations (IMO) in Perth.
IMO will assess the characteristics of the Mt Kokeby Kaolin Ore and its amenability to beneficiation processes for the generation of high-grade Alumina products and potential for High Purity Alumina (HPA) as part of its due diligence process.
Red Mountain will now undertake the metallurgical master composite by the size by size assay XRF analysis at various size fractions and to undergo a second and possible third stage of attritioner tests to provide information on the amenability of the ore to beneficiation processes for HPA.
Once regulatory approvals are received, a due diligence drill program will be undertaken.
Red Mountain is down 14.29 per cent on the market today and is trading at 0.6 cents each at 1:08 pm AEDT.
