Marcy Kiesman Highlights Quantum Critical Metals’ Babine South Silver and Mica-Based Gallium Extraction at PDAC 2026

Key Takeaways

• Silver grades up to 308 oz/t confirmed
• Mica comprises ~10% of pegmatite host
• Bench‑scale tests extracted gallium, rubidium, cesium
• Zinc and lead concentrations exceed 13,000 ppm
• Kilogram‑scale hydrometallurgy trials underway

Summary

Quantum Critical Metals highlighted its Babine South project at PDAC 2026, noting historic silver production dating back to the 1920s. Recent 2025 surface sampling returned silver grades from 10.9 ppm to 1,150 ppm, with independent re‑assays confirming up to 308 oz/t, alongside notable zinc and lead levels. The company also showcased bench‑scale success extracting gallium, rubidium, cesium, niobium and tantalum from mica‑rich pegmatites, moving toward kilogram‑scale hydrometallurgical trials. These developments position Babine South as a potential new source of both precious and critical metals.

Pulse Analysis

At PDAC 2026, Quantum Critical Metals used the Babine South project to underscore a resurgence of interest in British Columbia’s historic mining districts. The site, accessible by road and boat along Babine Lake, has transitioned from anecdotal 1920s silver reports to data‑driven exploration. Surface grab samples from the 2025 field program revealed a wide grade spectrum, with independent labs verifying extraordinary silver concentrations of 308 oz/t. Complementary zinc and lead anomalies further enhance the project's economic allure, suggesting a multi‑metal deposit that could support both primary and by‑product revenue streams.

Beyond traditional precious metals, Quantum Critical Metals is pioneering the extraction of critical elements from mica‑bearing pegmatites. Mica, typically relegated to waste, hosts up to 10% of the pegmatite matrix and concentrates valuable metals such as gallium, rubidium, cesium, niobium and tantalum. Recent bench‑scale experiments have demonstrated successful leaching of these elements, positioning the company at the forefront of a niche yet growing sector focused on sustainable critical‑metal sourcing. The shift from laboratory proof‑of‑concept to kilogram‑scale trials signals a commitment to scaling processes while minimizing environmental footprints through targeted hydrometallurgy.

If the laboratory successes translate to commercial viability, Babine South could become a strategic asset in North America’s critical‑metal supply chain, reducing reliance on Asian imports. Investors are likely to monitor the upcoming feasibility studies and permitting milestones, as the convergence of high‑grade silver and a portfolio of rare‑earth metals offers a compelling risk‑adjusted proposition. Continued data collection, metallurgical optimization, and clear regulatory pathways will be essential for unlocking the project's full value and delivering tangible returns to shareholders.
