A review of historical drill data has uncovered the potential of Tambourah’s Achilles project in Western Australia to host rare earth elements.

While Achilles was previously considered to be prospective for nickel-copper-PGE and gold mineralisation, data compilation and WAMEX reports have highlighted anomalous REE assays of up to 579 parts per million total rare earth oxides (TREO) over 4m composite samples in historical drilling at the Windidda South prospect.

This wide-spaced drilling by Creasy Group in 2007 was tested for multiple elements as REEs are often good pathfinders for gold mineralisation.

As such, the 4m composite samples could conceal individual high-grade REE zones.

Tambourah Metals (ASX:TMB) added that while the historical drilling tested an area of about 1,600m by 900m, the extent of the prospective saprolite within the larger project area is unknown.

It is also furthering its REE ambitions with applications for three new licences at Adam Range about 30km east of Laverton.

Achilles project

Achilles is located 220km north of Laverton with drilled by Creasy Group returning REE mineralisation in saprolitic clays between 12-36m deep in holes CBRC001, CBRC006 and CBRC007.

Additionally, holes CBRCO003 and CBRCO004 intersected variable sulphidic zone which provide encouragement for potential base metals and gold mineralisation while CBRCO005 intersected 1.35g/t gold from 260m over a four-metre composite interval.

Some copper enrichment of about 0.17% in two separate 4m intervals from a depth of about 200m was also noted in CBRCOO6.

Tambourah is planning to carry out a systematic aircore program that will test down to 100m for the presence of REE bearing saprolites within the area of the historical drill holes.

This could help the company figure out the extent of the REE mineralisation.

Adam Range

Meanwhile, the acquisition of the three licence applications adjacent to highly anomalous TREO assay grades which were recently announced by Mt Monger Resources has increased the company’s prospective REE holdings.

Mt Monger’s assays have confirmed the REE mineralisation contains a significant proportion of valuable heavy, magnet and critical rare earth oxides with the elevated assays reported as broad zones of shallow REE mineralisation hosted by saprolitic clays.

Adam Range is interpreted to have similar geology as the Mt Monger Resources’ project.
