Mount Ridley Mines Limited (ASX: MRD) — A Five-Week Catalyst Run Ends With a Claimed World's-Largest Scandium Resource

Written by Christopher Hall, AdvDipFP | Authorised Representative, AFSL 526688 | September 2026

Mount Ridley Mines Limited (ASX: MRD) is a Western Australian critical minerals explorer advancing the Grass Patch Complex, 25km north of the deep-water port of Esperance, toward scandium, heavy rare earth element (HREE) and gallium production. The company entered the FMP Top 10 momentum framework on the back of a five-week run of dated ASX releases — a Chief Technology Officer appointment, a mineralogy study, standout metallurgical results, a patent filing and, on 26 August 2026, a scandium resource upgrade the company describes as the largest publicly reported JORC-compliant scandium resource in the world. Each release built on the one before it, and it is that sequence — not a single headline number — that explains why MRD showed up as a market-leading share in this week's data.

Why Mount Ridley Appeared in the FMP Top 10

At the data-capture point used for this article, Mount Ridley Mines ranked #5 on the FMP momentum list, with a weekly gain of 31.25% (rank #3 for the week) and a quarterly gain of 61.54% (rank #19 for the quarter). The company had been on the FMP Top 30 momentum list for 13 sessions and had been flagged on the FMP Launch Pad — the pre-catalyst early-identification tier of FMP's proprietary research — for 28 sessions, returning 55.56% since it first entered the Launch Pad. These figures were captured intraday, on the day the underlying data was pulled for this article — they reflect a provisional, not a settled closing, price, and should be read with that qualification.

The catalyst behind the move was not one announcement but five, all price-sensitive and all lodged with the ASX inside a single five-week window:

• 22 July 2026 — Appointment of Chris Larder as Chief Technology Officer, the metallurgist behind Mount Ridley's proprietary Selectro™ leach process.

• 6 August 2026 — TIMA (automated mineralogy) results confirming Grass Patch's rare earths sit in discrete phosphate minerals, opening a beneficiation pathway.

• 12 August 2026 — Initial Selectro™ metallurgical testwork results, showing materially higher recoveries than the industry-standard hydrochloric acid (HCl) leach across the company's scandium, rare earth and gallium suite.

• 19 August 2026 — A provisional patent application lodged for the Selectro™ Process.

• 26 August 2026 — The Grass Patch scandium Mineral Resource upgraded to 946Mt, which Mount Ridley states is the largest publicly reported JORC (2012) scandium resource globally.

What Pattern Did Mount Ridley Show?

This is an episodic pivot rather than a classic technical base: the share re-rated in response to a chain of company-specific news, not a chart formation building over weeks of quiet trading. Pradeep Bonde, the trader who developed the episodic pivot methodology, has made the same point about news-driven moves generally:

"Almost every one of these stocks which made a 50% move had a catalyst. News moves stocks. Chart patterns doesn't really matter if there is news. Focus on news, not chart patterns. Chart patterns are important but why did the stock move? Because there is a catalyst."

— Pradeep Bonde

Mount Ridley's run fits that framing closely: five distinct, dated, verifiable catalysts inside five weeks, each one lodged directly with the ASX rather than sourced from commentary or speculation. What distinguishes it from a single-event episodic pivot is that each release built directly on the one before — the CTO appointment put the metallurgist in place, the TIMA study explained how the rare earths were hosted, the Selectro™ results demonstrated recovery, the patent protected the process, and the resource upgrade extended the scale of what that process now has to work with. Traders learning the setup can find the mechanics of an episodic pivot setup in FMP's dedicated guide, and see the FMP momentum research hub for the full weekly Top 10 list Mount Ridley entered.

About Mount Ridley Mines and Its Core Asset

Mount Ridley Mines is an Australian critical minerals explorer whose flagship asset, the Grass Patch Complex, hosts co-located scandium, heavy rare earth element and gallium mineralisation across a single regolith-hosted system in Western Australia. The project sits within a strike length of roughly 70km and an average width of 13.5km, with only around 20% of the Grass Patch Complex drill-tested to date and 82km of secondary gravity targets identified across seven prioritised walk-up drill areas (Mount Ridley Mines Limited, 26 August 2026, "Scandium Resource Upgraded to 946Mt at the Grass Patch Project").

Within that resource base, the scandium estimate is the standout figure. On 26 August 2026 Mount Ridley reported an upgraded Inferred Mineral Resource of 946Mt at 50.1ppm scandium (76.8ppm Sc₂O₃), for 47,357 tonnes of contained scandium metal — up from 367.98Mt at the company's prior estimate, reported 28 January 2026. Mount Ridley states this makes Grass Patch the largest publicly reported JORC-compliant scandium resource in the world; that characterisation is the company's own and has not been independently verified by FMP. Managing Director Allister Caird described the upgrade as follows:

"We've now established the world's largest publicly reported JORC compliant scandium resource, at a time when the commodity is under intense focus from governments and industry seeking to secure supply outside China. Holding the largest scandium resource in the world, alongside our proprietary Selectro™ Process, provides a genuine pathway for Mount Ridley to commercialise this resource together with our broader commodity base at Grass Patch."

— Allister Caird, Managing Director & CEO, Mount Ridley Mines

The increase was driven primarily by re-assaying 3,271 historical aircore and diamond drill pulp samples rather than new drilling — a lower-cost route to resource growth that the company says has not yet been exhausted, with roughly 80% of the Mount Ridley tenure still untested for scandium.

Alongside scandium, the company also holds an Inferred HREE resource of 122.5Mt at 889ppm total rare earth oxide (TREO), including 41% HREO composition and roughly 5,000 tonnes of contained dysprosium and terbium, and an Inferred gallium resource of 838.7Mt at 29.3ppm gallium (24,584 tonnes contained gallium metal). The 6 August 2026 TIMA (automated mineralogy) study, conducted by AXT Pty Ltd, confirmed that the rare earths at Grass Patch sit almost entirely within three discrete phosphate minerals — xenotime, crandallite group phosphates, and monazite/rhabdophane — rather than being loosely adsorbed onto clay as in a simpler ionic-clay deposit. That distinction matters for processing: a phosphate-hosted deposit opens the door to physically concentrating the rare earths via flotation before leaching, cutting the volume of material that has to be processed downstream.

The Selectro™ Metallurgical Results

The 12 August 2026 metallurgical results are the technical core of the run. Independent testwork by Nagrom Pty Ltd, an accredited Perth metallurgical laboratory, compared Mount Ridley's proprietary Selectro™ leach process against a conventional hydrochloric acid (HCl) baseline, on aliquots drawn from the same 16.8kg composite of historical Grass Patch drill material. Selectro™ recovered heavy rare earth elements at 77–83%, scandium at 80.0%, light rare earth elements at 70–77%, and gallium at approximately 56% — against an HCl baseline of 0–51% across the same elements. Gallium is the sharpest contrast in the dataset: the HCl comparison recovered zero gallium, while Selectro™ consistently recovered more than 55% across both tests.

Mount Ridley's own announcement is explicit that these are first-pass, unoptimised results, generated from roughly 90-gram laboratory-scale aliquots without prior beneficiation, and should not be read as indicating commercial-scale recoveries or process economics. Chief Technology Officer Chris Larder, who developed the Selectro™ Process, framed the result this way:

"The Selectro™ Process is the culmination of over a decade of development and refinement, so it is very encouraging to see the technology deliver strong results on Mount Ridley material. These results provide further confidence in the process and support its progression into the next phase of optimisation and larger-scale testwork."

— Chris Larder, Chief Technology Officer, Mount Ridley Mines

Seven days later, on 19 August 2026, Mount Ridley lodged a provisional patent application for the Selectro™ Process, held through its wholly owned subsidiary Mount Ridley Tech Pty Ltd. A provisional filing establishes a priority date and gives the company a 12-month window to pursue full patent protection in Australia and overseas — it is a filing, not a granted patent, and the commercialisation pathway it protects (whether at Grass Patch, through third-party licensing, or both) remains at an early stage. Management has indicated the company intends to progress a bulk testwork program incorporating flotation, a scoping study, and discussions with prospective third parties over the remainder of 2026 and into 2027, alongside continuing engagement with Oak Ridge National Laboratory, Lawrence Livermore National Laboratory and Germany's Fraunhofer Institute on separation science.

Thematic Context

Scandium, gallium and heavy rare earth elements sit among the most supply-concentrated critical minerals tracked by international bodies. According to the International Energy Agency's Global Critical Minerals Outlook 2025, China dominates refining for 19 of the 20 minerals it classifies as strategic, at an average share of roughly 70% — and Mount Ridley's own three target commodities sit toward the extreme end of that concentration, with non-Western supply shares the company's investor materials place at 95% for scandium and 98% for gallium (citing USGS Mineral Commodity Summaries data). That concentration has drawn direct government intervention: in August 2026 the U.S. Department of War's Office of Strategic Capital committed a conditional US$400 million loan to Sunrise Energy Metals Limited (ASX: SRL) to expand its Syerston scandium project — evidence, cited in Mount Ridley's own announcement, that allied governments are now underwriting non-Chinese scandium supply directly rather than leaving it to the market alone.

Mount Ridley is not the only Western Australian miner to enter the FMP Top 10 recently. How Cauldron appeared in the FMP Top 10 covers Cauldron Energy (ASX: CXU), a WA-based uranium explorer, and King River Resources' FMP hub page covers King River Resources (ASX: KRR), a WA gold explorer — both entered the list in the same broad window as part of a wider pattern of WA-jurisdiction explorers showing up in FMP's proprietary momentum data.
