Meeka has flagged assay results from 85 holes drilled within the western block of the Cascade REE Project in WA which show shallow, high-grade, and ‘spectacular’ mineralisation. 

A total of 52 of the 85 holes returned shallow, broad, high-grade intersections up to 4,029ppm Total Rare Earth Oxides (TREO) in saprolitic clays.

Importantly, the company says the high value magnet rare earths and critical rare earths account for an average of 26% and 25% of TREO grades respectively.

Results include:

  • 7 metres at 3,826ppm TREO from 36m including 3 metres at 4,029ppm TREO;
  • 3 metres at 1,989ppm TREO from 16m;
  • 16 metres at 1,683ppm TREO from 0m including 4 metres at 2,587ppm TREO;
  • 12 metres at 1,373ppm TREO from 20m (MGA076)
  • 5 metres at 1,178ppm TREO from 48m; and
  • 29 metres at 629ppm TREO from 8m including 1 metre at 3,729ppm TREO (MGA118).

Assays for a further 105 holes from the eastern block of Cascade are expected in late May 2022.

Results show large scale potential

Meeka (ASX:MEK) CEO Tim Davidson said the results show remarkable scale potential, with Cascade – at 2,068km2 – representing a potentially large-scale, high-grade rare earths project.

“We are seeing shallow, broad, high-grade intersections over a large area,” he said.

“Results from the eastern block are due in late May 2022 and may expand the scale even further.

“Importantly, the results contain high levels of permanent magnet metals being neodymium-praseodymium oxides.

“These metals are geopolitically critical, and we intend to accelerate our understanding of Cascade with drilling commencing on the back of results from the eastern block and metallurgical testwork expedited.”

Once the remaining assay results are received the company plans to detail a forward activity plan targeting the highest value (high heavy and magnet REO content) zones of mineralisation.

Clay-hosted REE an economic advantage

Meeka plans to expedite initial metallurgical work to understand the process for producing a commercial product from Cascade, which is a clay-hosted REE project.

Notably, clay hosted projects often enjoy significant project and cost advantages compared to hard rock projects, with cheap bulk mining and a simple process flow sheet.

Clay deposits do not require the expensive comminution and beneficiation processes that hard rock deposits require, resulting in a lower capital intensity and lower operating cost to produce a refined product.

The high proportion of magnet rare earth elements (neodymium-praseodymium) in clay deposits also results in a high value product.

And they don’t produce the costly radioactive tailings waste that is often a by-product of processing hard rock deposits.
