Quantum Critical Metals Corp. (TSXV: LEAP | OTCQB: ATOXF | FSE: 86A) has announced an advanced mineral mapping program at its wholly owned Discovery Property in the Eeyou Istchee James Bay region of Québec, targeting gallium, rubidium, cesium, and other critical minerals. The program will analyse nine historical samples collected in 2018 from drill core and surface material, eliminating the need for new drilling. The work is designed to confirm mineral speciation and guide future metallurgical testwork, a step investors in the critical minerals sector may be watching closely given growing North American supply-chain priorities.

Key Points

  • Quantum Critical Metals Corp. (TSXV: LEAP | OTCQB: ATOXF | FSE: 86A) initiated the mineral mapping program in September 2026
  • Nine historical samples from 2018 drill core and surface material will be laser-scanned by Elemission Inc. of Montreal
  • GMY Consulting Inc. has been engaged to interpret results; all findings will inform potential processing route selection
  • Investors should watch for the company's report on findings and potential progression to bench-scale flotation testing

Laser-Based Mapping to Identify Critical Mineral Hosts at Discovery Property

Elemission Inc. of Montreal will conduct laser-based mineral mapping across all nine samples, producing detailed mineral and element maps showing the concentration, location, and mineral associations of gallium, rubidium, cesium, and other critical minerals present at the Discovery Property. The release states that standard assays identify quantities of metal but do not reveal the minerals in which those metals occur. This speciation data is described by the company as essential to designing effective processing strategies, distinguishing critical-mineral-bearing phases from barren material, and understanding how target minerals may be concentrated.

How Historical 2018 Samples Support Cost-Efficient Technical Advancement

The company states that the nine samples were collected by Quantum in 2018 and that no new drilling was required for this program. CEO Marcy Kiesman noted in the release that using previously collected material allows the company to obtain important technical information without undertaking a new drill program. Historical work at Discovery confirmed the presence of gallium and rubidium through certified assays, but did not determine mineral deportment. This program is intended to fill that gap and identify which rock types and mineral phases warrant focus in future exploration and development work.
