Battery Age Reports Rubidium at 11,400 ppm and 54m Lithium Intercepts at Falcon Lake

Falcon Lake Emerges as a Multi-Critical Metal Hub

Battery Age Minerals Ltd (ASX – BM8) has released compelling assay results from its Falcon Lake Lithium Project in Ontario, Canada, confirming the presence of not only high-grade lithium mineralisation but also significant concentrations of several critical metals. The latest multi-element analysis reveals rubidium levels reaching as high as 11,400 ppm, tantalum up to 2,300 ppm, caesium at 2,600 ppm, and gallium nearing 96 ppm. These findings elevate Falcon Lake’s profile from a lithium-focused asset to a strategically important source of multiple critical minerals.

Exceptional Lithium Drilling Complements Critical Metals

The lithium intercepts reported are impressive, with several drill holes returning thick spodumene-bearing pegmatite zones exceeding 50 metres at grades above 1.4% lithium oxide (Li2O). Such intervals underscore the project's potential to supply high-quality lithium, a metal central to electric vehicle batteries and energy storage technologies. The coexistence of lithium with tantalum, rubidium, caesium, and gallium, each vital to high-tech, aerospace, and defence industries, adds a valuable multi-commodity dimension to the project.

Exploration Upside Remains Substantial

Despite these encouraging results, only 5 of the 30 high-priority targets identified through geophysical surveys and surface sampling have been drill tested to date. This leaves a vast portion of the mineralised corridor at Falcon Lake largely unexplored, offering significant scope for further discoveries. The project’s geological setting, described as a highly evolved lithium-cesium-tantalum (LCT) pegmatite system, is comparable to notable Canadian deposits such as the Tanco Mine and Aubry pegmatites, reinforcing its potential.

Strategic Importance of Critical Metals

The critical metals identified carry considerable strategic weight. Tantalum is essential in electronics and defence applications, caesium is used in atomic clocks and specialist drilling fluids, rubidium plays a growing role in quantum computing and fibre optics, and gallium is a key component in semiconductors and AI chips. Notably, rubidium commands prices exceeding US$1,000 per kilogram for high-purity compounds, reflecting its rarity and supply constraints. Falcon Lake’s enrichment in rubidium, with over a third of samples exceeding 2,000 ppm, positions Battery Age to potentially tap into this niche but lucrative market.

Next Steps and Market Positioning

Battery Age plans to advance its exploration with targeted geochemical and geophysical work to refine additional pegmatite targets. Metallurgical test work is also slated to evaluate the feasibility of recovering tantalum, caesium, rubidium, and gallium alongside spodumene concentrate production. With lithium prices showing signs of recovery, the company is well positioned to capitalise on the strengthening commodity markets, leveraging Falcon Lake’s multi-element potential to enhance shareholder value.
