Coppermoly Completes Wyemandoo Acquisition as Critical Minerals Prices Soar

Strategic Acquisition Expands Critical Minerals Portfolio

Coppermoly Limited (ASX:COY) has completed the acquisition of a 100% interest in the Wyemandoo Project in Western Australia, significantly boosting its exploration footprint to 1,805 square kilometres across WA and Queensland. The purchase includes four tenements, E57/1017, E58/555, E58/571, and E59/2431, acquired from Aldoro Resources Ltd (ASX:ARN) and Altilium Metals Pty Ltd, marking a major step in Coppermoly's push into high-demand battery and technology metals.

The Wyemandoo Project, located about 80 kilometres southeast of Mount Magnet, sits on the southeastern margin of the Windimurra Igneous Complex. It is characterised by a 10-kilometre-plus pegmatite corridor rich in critical minerals including tungsten (W), rubidium (Rb), titanium (Ti), and tantalum (Ta). This acquisition complements the company’s existing Queensland tenements and aligns with the growing global appetite for these metals, especially tungsten and rubidium, whose prices have surged dramatically over the past year.

High-Grade Critical Minerals Drive Exploration Focus

Rock chip assays from Wyemandoo reveal tungsten concentrations ranging from 0.01% up to an eye-catching 13.1% within a 4.5-kilometre corridor. Tungsten prices have skyrocketed, with ammonium paratungstate (APT) reaching USD $3,185 per metric tonne unit in April 2026, a near 900% increase over 12 months, driven by geopolitical tensions and its strategic role in defence manufacturing.

Rubidium assays also stand out, with rock chips showing grades up to 1.82% Rb and drill holes intercepting widths of 2 to 20 metres at grades above 0.1% Rb₂O. Rubidium commands premium prices between USD $3,000 and $7,000 per kilogram depending on purity, underpinning its critical use in atomic clocks for telecommunications and GPS systems. The metal’s strategic importance is underscored by its demand in defence and advanced technology sectors, including satellite networks planned by major tech entrepreneurs.

Titanium and tantalum mineralisation further bolster Wyemandoo’s profile. Titanium grades in rock chips range from 0.01% to 1.66%, with the global market expected to grow from USD $28.2 billion in 2025 to nearly $38 billion by 2030, driven largely by aerospace demand. Tantalum concentrations vary widely up to 4,800ppm, with European prices rising above USD $200 per pound amid surging demand in electronics and aerospace.

Queensland Exploration Delayed by Specialist Shortages

Meanwhile, Coppermoly’s Queensland projects at Mt Isa and Cloncurry saw no geophysical surveys during the March quarter. The company’s preferred geophysicists were overseas, delaying high-resolution ground magnetics surveys that are critical for detecting subtle near-surface targets. These ground surveys, offering superior accuracy compared to aeromagnetics, are now scheduled for the current quarter following the return of the specialists.

Additionally, Coppermoly dropped its Exploration Permit for Minerals Application (EPMA) 29002 Jessieval after being ranked second to another applicant by the Queensland Department of Natural Resources and Mines. The company opted not to pursue the available non-overlapping blocks, focusing instead on higher-priority projects.

Financial Position Reflects Ongoing Investment in Growth

Financially, Coppermoly reported a net cash outflow of $63,000 from operating activities and $183,000 from investing activities during the quarter, primarily reflecting exploration spend and the Wyemandoo acquisition cost of $100,000. The company closed the quarter with $442,000 in cash, providing an estimated three quarters of funding at current expenditure levels. Payments to related parties, including director fees, totalled $50,400.

The company’s exploration strategy at Wyemandoo includes planned reverse circulation (RC) drilling targeting tungsten in the third quarter, followed by grid geochemical sampling and geophysical gravity surveys to identify denser metals such as tungsten, tantalum, titanium, and rubidium. This methodical approach aims to prioritise large mineral systems over isolated high-grade hits, seeking to unlock the full potential of the pegmatite corridor.

Coppermoly’s recent expansion and exploration plans follow a series of developments that have steadily increased its exposure to critical minerals, which are central to emerging technologies and defence applications. The company’s move to secure the Wyemandoo Project builds on prior announcements detailing its growing portfolio and strategic focus on battery and tech metals in Australia’s premier mining jurisdictions Coppermoly Boosts Critical Minerals Portfolio and Coppermoly Advances WA Tungsten Project.
