Quantum’s NMX East Heats Up: PGE Potential Emerges Next to Rapidly Expanding Polymetallic District
Vancouver, BC – June 10, 2025 – Quantum Critical Metals Corp. (TSX.V: LEAP | OTCQB: ATOXF | FSE: 86A1)
("Quantum" or the "Company") is exploring the possibility of a poly-metallic play, in addition to gallium,
rubidium and cesium , on its wholly owned NMX East project, located in the Eeyou Istchee James Bay
Region of Québec.
Previous news releases have discussed the discovery of 107.69 meters of 38.85 gpt g allium, 701 gpt
rubidium, 24.98 gpt cesium and 3.61 gpt thallium from surface in diamond drilling on a pegmatite on the
property, with plans for metallurgical testing underway. Additionally, Quantum is investigating the
presence of the Bande du Lac des Montagnes rock formation outcropping near the eastern border of the
NMX East project - a rock formation known to host platinum group elements (“PGE”) or polymetallic
mineralization in the region.
Power Metallic Mines Ltd.’s (TSX.V: PNPN) Nisk deposit is hosted in the Bande du Lac des Montagnes
(“BLM”), a volcano-sedimentary belt comprising paragneiss, orthogneiss, amphibolite, and mafic volcanic
rocks. The BLM belt is reported to be 3 to 8 km wide, strikes 060 to 065 and is approximately 140 km long.
Mineralization at Nisk is hosted within an elongated ultramafic body, and this ultramafic intrusion includes
layered pyroxenite, peridotite, and serpentinized dunite, forming a layered mafic -ultramafic intrusive
complex. The mineralized zone is at the base of the serpentinized dunite and features semi -massive to
massive sulphide accumulations, characteristic of magmatic Ni -Cu-Co-PGE systems (Power Nickel
Amended NI43-101).
The NMX East project is located along the NISK shear zone, approximately 8 km from the western edge of
the NISK Pro perty. According to regional mapping completed by the Ministry of Natural Resources and
Forestry of Quebec, the BLM outcrops less than 100 metres from the eastern edge of the NMX Project
area (Figure 1).
Power Metallic announced on June 9 th, 2025, that the company “Acquires 167km2 from Li -FT Power,
expanding project area by over 300%” which includes claims adjacent to Quantum’s NMX East property
on the north, south and western borders, Power Metallic Acquires 167Km² from Li-FT Power, Expanding
Nisk - Lion Polymetallic Project Area by over 300%.
CEO Marcy Kiesman commented:
“This development is a significant win for Quantum shareholders. With no added cost, we now find
ourselves adjacent to a rapidly expanding polymetallic district, further enhancing the strategic value of
our NMX East project. Our early staking strategy is proving its merit as we continue to unlock multi-metal
potential across our portfolio. The scale of activity planned by Power Metallic including the 100,000
metres of drilling recently announced validates the regional geology and reinforces our belief that th e
region is on the cusp of a major discovery surge.”

Next Steps:
The Company is planning a field reconnaissance to determine if the Bande du Lac des Montagnes outcrops
on the NMX East property. Quantum plans to discuss with geophysics companies to determine the best
fit for the project and to test the possibility of PGE mineralization below surface.
Quantum also announces the grant of 3,000,000 stock options to consultants, directors and officers which
are exercisable at twelve cents for a period of five years from the date of grant, expiring June 9, 2030.
