Quantum Completes Site Visit at NMX East, Québec
Vancouver, BC – August 12, 2025 – Quantum Critical Metals Corp. (TSX.V: LEAP | OTCQB: ATOXF | F SE:
86A1) ("Quantum" or the "Company") is pleased to announce that it has successfully completed a site visit
to its wholly owned NMX East project, located in the Eeyou Istchee James Bay region of Québec.
The focus of the site visit was to assess the southeastern portion of Quantum’s NMX East claims for
potential mafic outcrops and to investigate the magnetic high identified by Québec government
geophysics. The area had not previously been examined during earlier peg matite focused exploration.
(see Figure 1, black circled area). Geological mapping and sampling were conducted, and selected samples
are being analyzed to determine if an ultramafic rock package with the potential of hosting critical
minerals is present.

The site is strategically located near Power Metallic Mines Inc. (TSXV-PNPN) which announced a recently
expanded land position near its Nisk -Lion-Tiger polymetallic discoveries. On June 9 th, 2025, a land
acquisition of 167 km² from Li -FT Power Ltd. (TSXV -LIFT) highlighted the regional development and
underscores the broader area’s potential for polymetallic exploration. Power Metallic Acquires 167KM²
from Li-FT Power, Expanding Nisk - Lion Polymetallic Project Area by over 300%
CEO Marcy Kiesman emphasized Quantum’s unique advantage:
"We’re pleased to have both confirmed pegmatite-hosted mineralization in the north and promising signs
of ultramafic rock potential in the southern part of the property. While it’s still early days, having more
than one type of mineral system on the same project could increase our chances of making a meaningful
discovery. We’re looking forward to the lab results to help guide our next steps."
Quantum key developments on NMX East 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.
