Quantum Critical Metals Advances Mineralogy and Metallurgy for James Bay Projects
Vancouver, BC – May 30, 2025 – Quantum Critical Metals Corp. (TSX.V: LEAP | OTCQB: ATOXF | FSE: 86A1)
("Quantum" or the "Company") is pleased to announce it has entered into a nondisclosure agreement
with a specialized processing and hydrometallurgy laboratory to initiate metallurgical testing for its
Discovery and NMX East projects, located in the Eeyou Istchee James Bay region of Québec.
Key Developments:
• 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
In a strategic move, 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. Gallium and other critical
elements are essential to critical next-generation technologies. By tackling the processing challenge now,
we aim to help fill the growing global supply gap in addition to the growing price escalations which are
competitive with gold.”

Next Steps:
The Company will collect larger sample volumes from both sites to send to multiple hydrometallurgy
laboratories for process optimization. Additional updates will be provided as results become available.
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 e nergy. Gallium is also used in semiconductors, AI
circuitry, radar and microchips and could be more critical than previously realized.

Gallium Market Size and Growth:
1. Market Size
In 2023, global high -purity gallium production was estimated at 320 tonnes, with total primary
production capacity reaching 1,100 tonnes per year. Demand for gallium is projected to grow due to
its role in semiconductors, 5G technology, and renewable energy applications.
2. Key Applications:
● Semiconductors: Gallium arsenide (GaAs) and gallium nitride (GaN) are critical in chips for
smartphones, satellite communications, and defense systems.
● Renewable Energy: GaN is used in solar cells and LEDs.
● Emerging Technologies: Gallium is a key component in next -generation technologies such as
quantum computing, 5G networks, and advanced radars.
3. Geopolitical Considerations:
China has imposed export controls on gallium, exacerbating supply chain challenges for the U.S. and its
allies. These restrictions are part of a broader trade conflict over critical technologies. Countries like the
USA are ramping up efforts to develop dom estic gallium sources and processing capabilities to reduce
reliance on China.

About Critical Metals
Critical metals are essential components in modern technologies, including renewable energy systems,
defense applications, and advanced electronics. Both the United States and Canada have identified
specific lists of critical minerals vital to their economic and national security. The U.S. Geological Survey’s
2022 list includes 50 critical minerals, while Canada in 2024 has designated 34 minerals as critical.
Recent geopolitical developments have heightened concerns over the supply chain security of these
critical metals. China, which holds a dominant position in the production and processing of several critical
minerals, has implemented export bans affecting t he West. These actions underscore the strategic
importance of diversifying supply chains and developing domestic sources for critical metals to mitigate
geo-political risks and ensure the stability of essential industries.
