Battery Age Minerals has confirmed the presence of high grade rubidium at its Falcon Lake Lithium Project in Ontario, Canada, following recent drill results that also delivered strong lithium grades. This new development adds an additional high value commodity to the company’s growing resource portfolio and further enhances the potential of the project.
The latest assays returned rubidium oxide grades of up to 0.37 percent, occurring within spodumene bearing pegmatites that also host significant lithium mineralisation. Importantly, rubidium was intersected in several holes, suggesting it may be more widespread across the deposit than previously known. The company is now assessing the extent and consistency of rubidium mineralisation, as well as its economic significance alongside the lithium zones.
Rubidium is a rare alkali metal that is used in advanced technologies including specialty glass, electronics, and medical imaging equipment. It commands a high market price due to its scarcity and the complexity of its production. Identifying high grade rubidium within an already promising lithium project represents a strategic advantage, giving Battery Age Minerals the potential to benefit from multiple high value products.
Managing Director Gerard O’Donovan described the discovery as a significant and exciting development. He said the combination of strong lithium and high grade rubidium positions Falcon Lake as a project of increasing strategic importance, both for the company and for future supply chains in the clean energy and technology sectors.
Falcon Lake is located in a well established lithium district with excellent infrastructure and access to skilled labour. Earlier drilling programs had already confirmed strong lithium grades, and the addition of rubidium to the mix is expected to attract further attention from investors and potential offtake partners.
Battery Age Minerals plans to continue drilling and geological analysis to define the size, grade, and distribution of rubidium and lithium mineralisation. The company will also investigate potential synergies in processing and marketing the two commodities, with the ultimate goal of advancing the project toward development.
