Vancouver, BC – TheNewswire - July 25, 2025 – Quantum Critical Metals Corp. (TSX.V: LEAP | OTCQB: ATOXF | FSE: 86A1) ("Quantum" or the "Company") is pleased to announce that a core test sample from the NMX East has been submitted for metallurgical test work to SGS Lakefield, Ontario. The NMX East project is located in the Eeyou Istchee James Bay region of Québec.
In late June, a team sampled the core that was drilled in 2023 to make up a test sample for processing and metallurgy. The core had previously been cut in half, sampled and assayed. The assay results revealed anomalous gallium, rubidium and cesium which were reported on March 13, 2025 after assay results were re-evaluated due to changes in gallium supply worldwide (Click Here).
A sample weighing over 40kg was submitted which was taken from the remaining core from hole DNW 2023-03 from 8.92m- 116.5m. Since the core was previously cut in half, it was halved again resulting in two quarters, one quarter of the remaining core was sampled for submission to the laboratory, leaving one quarter of the core remaining in the box. Figure 1 shows the cut core ready for sampling.
The purpose of this test work is to investigate the mineralogical association of gallium, rubidium and cesium (and other elements), to process the core to isolate the minerals of interest, and to conduct proof of concept hydrometallurgy to extract these metals.
Quantum key developments to date:
-
Significant Critical Metals Discoveries
A detailed reassessment of drill core assays from both Québec projects has confirmed elevated and consistent intervals of gallium, rubidium, cesium, niobium, and tantalum. These results support the identification of two distinct gallium-rubidium-cesium mineralized systems within the Company’s portfolio.
-
Early Metallurgical Focus to Accelerate Recovery Assessment
Quantum is prioritizing mineralogical and metallurgical studies ahead of a formal resource estimate to evaluate the economic viability of metal recovery. This proactive approach aims to fast-track development and position the Company at the forefront of critical metal supply efforts in North America.
-
Innovative Gallium Recovery from Mica
Initial findings suggest gallium may be hosted in mica, a non-traditional source. While gallium is typically extracted as a byproduct of bauxite or zinc processing, historical studies show it can be recovered from mica using processing methods like floatation, followed by hydrometallurgy acid leaching techniques. The Company is engaging multiple laboratories to optimize this process.
-
Strengthening Domestic Supply Chains
In light of China’s December 2024 ban on gallium exports, Quantum’s discoveries represent a timely and strategic opportunity to support North American critical mineral independence. These metals are essential for high-tech applications, including semiconductors, telecommunications, defense, and renewable energy.
CEO Marcy Kiesman commented:
“While advancing metallurgy early in a project’s life cycle may be historically unconventional, it reflects our urgency and commitment to unlocking domestic sources of critical metals. We believe solving the processing piece first will accelerate the development of our assets and fill the global supply gap of these minerals.”
About Gallium
Gallium, a critical component in semiconductors, telecommunications, renewable energy sectors and may also be considered as a possible heat exchange medium in nuclear reactors. Canada and the USA rely on gallium for telecommunications, defense, and green energy. Gallium is also used in semiconductors, AI circuitry, radar and microchips and could be more critical than previously realized.

About Rubidium
Today most rubidium is obtained as a byproduct of lithium and since it is easily ionized it can be used to propel spacecraft engines (ion). Rubidium’s critical role in emerging technologies and its limited supply make it a valuable strategic resource.
1. Market Size and Growth:
Rubidium is a niche market, with an estimated global annual consumption of less than 2,000 kilograms, primarily for high-tech applications. Prices for high-purity rubidium compounds are significant, often exceeding $1 million per tonne for rubidium oxide, driven by its rarity and specialized uses.
2. Applications:
-
Specialty Glass: Used in fiber optics and night-vision technology.
-
Telecommunications: Serves as an atomic frequency standard in GPS systems.
-
Quantum Computing: Ultra-cold rubidium atoms play a key role in quantum research.
-
Batteries: Potential use in sodium-ion batteries, an emerging alternative to lithium-ion technology.
3. Growth Drivers:
Advances in quantum computing and demand for robust, low-temperature battery technologies are expected to boost rubidium consumption. The inclusion of rubidium on critical minerals lists highlights its strategic importance, especially as global reliance on China’s supply raises supply chain concerns.
4. Geopolitical Factors:
China’s dominance in rubidium production and recent export restrictions have prompted countries like the U.S. and Australia to accelerate exploration and development of domestic resources.
