Mount Ridley Mines Limited (ASX:MRD) is consolidating a Rare Earth Project in Western Australia.

Updated: Mar 29, 2023

✦ Guy Le Page, Non-Executive Director of Mount Ridley Mines Limited (ASX: MRD) explains why their story is one you need to follow. Resource is almost a certainty. Patience is key.

The Esperance region is fast developing into a Rare Earth Region. And the Mount Ridley Story is all about clay hosted Rare Earth Elements (REE) deposits.

The million dollar question for all the clay REE projects is about the timing of the unlocking of the metallurgical conundrum. Yes this is an obstacle for companies, but whether this is a matter of Time or Market remains to be seen.

The Mount Ridley Story

The clay hosted REE deposits that Mount Ridley has are located within a Fraser Range sub-basin, just 50km north of Esperance. Interestingly, it was initially acquired for its nickel and copper sulphides potential.

Mount Ridley is one of many companies that is applying their trade in the Esperance region. The MRD story is with good company. The Company also holds approximately 18% of the Weld Ranges in the mid-west of Western Australia. Areas of the tenements are prospective iron and gold.

The Sensitivity of Supply Deficit and Price Volatility

The supply crunch of metals have been talked about for nearly 8 years. Noel Ong has been writing about this topic since 2019 and yet, the crunch sort of never came.

Samso Insights:

An example of this was the Zinc story. Nickel and Copper made an appearance but it's still very much a waiting game. It was a lot of hype that never came to pass.

Then again, in our industry we do need to keep our eyes and ears peeled. Over the last six months, we saw the Nickel Push and the Copper Run. Uranium seems to be taking the lead as well. If you've been following the news and developments, the surge in buying by the Sprott Uranium Fund may have created a catalyst for commentators to feed on. Tune in to Guy Le Page's conversation here to get more insights.

You would also have noticed that the price of Molybdenum ran spectacularly in January 2023 and observers commented that this is due to China restarting production and the closure of mines in Peru.

If that is so, then a nearly 95% jump in price would make any punter wake up. On the REE front, according to Strategic Metals Invest (, since January 2020, Dysprosium has increased by up to 78.25%, Neodymium 226% and Praseodymium 169.20%.

Samso's Conclusion

The clay hosted REE journey is one that is intriguing a lot of investors. When will the Holy Grail show itself? Will there be a market for it then? And how will the technology using these metals develop then?

Needless to say, with so much happening around, we are seeing a pivoting of industries. Undeniably, the world of electrification is here to stay. We are looking at a new world of efficiency in creating cleaner energy.

The irony is Rare Earths are not rare at all. But the concentration of the resources and the application to downstream products are rare. The dependence on one single "nation" to produce everything is growing less popular.

The Esperance region is ideal for a new industry to emerge. With the space to grow in size, it also has all the important logistics like a port and a low density of population.

For Mount Ridley, the resource is almost a certainty. The unlocking of the metallurgical question will herald exciting times ahead for all involved. For investors, the hardest thing to do is to be Patient. But perhaps while waiting, instead of getting ants in your pants, why not DYOR (Do Your Own Research) and keep abreast of all that's developing?

About Mount Ridley Mines Limited (ASX:MRD)

Mount Ridley Mines Limited is undertaking the exploration of a significant deposit of valuable clay-hosted rare earth elements in Western Australia. The Project was initially acquired for its nickel and copper sulphides potential and is now recognised as being prospective for ionic clay REE deposits.

Currently, this style of deposit is mined and processed only in China and Myanmar.

In November 2020 Mount Ridley Mines Limited (“MRD”) commenced a review of data for its namesake Mount Ridley Project and surrounding area.

The review concluded that areas of the Biranup and Nornalup geological provinces in south-eastern Western Australia have the potential for REE mineralisation, and in particular, the style of mineralisation referred to as Ionic Adsorption Clay (IAC-REE).

Globally, deposits of IAC-REE are most significant in southern China and are the world’s main source of heavy Rare Earth Elements.

The Project

REE mineralisation occurs as large, horizontal, near surface, sheet-like lenses up to a depth of 89 metres. REE mineralisation is interpreted to be present within the in-situ saprolite clay horizon. Patchy lower grade zones occur within transported cover which may vector towards stronger REE mineralisation deeper within the regolith.

Geological Survey of Western Australia (DMIRS) mapping [1] shows that the Mount Ridley Project REE mineralisation occurs within the weathered mantle (regolith) of the Recherche Super-suite, which is described as “granitic and mafic gneiss; may include intrusions of Esperance Super-suite”.

While the source of the REE mineralisation is currently unknown, a detailed sample and litho-geochemistry dataset from bottom of hole aircore samples have been established which includes whole-rock chemical analyses, sample pulps and some end-of-hole air core samples. These samples and data are being studied by the Company’s consultant geochemist to identify the primary rock-type and whether units are REE-enriched.

Re-assay of 950 air core samples (162 pending) returned significant REE values over an apparent strike in excess of 25 km with over 20 samples returning >1,000 ppm Mineralisation remains open in all directions with a peak value so far at the Keith’s Prospect from MRAC0711 with 10,461ppm (1.05%) from 23m downhole.

Significant REE intersections have been identified and grouped into 5 prospects – Winston’s, Keith’s, The Lake, Tyrell’s and Marcellus.

Planning underway for a 25,000m aircore program to test newly acquired tenements in addition to step-out and infill holes.
