Quantum Discovers Evidence of Mafic-Ultramafic Rocks at NMX East, QC
Vancouver, BC – August 14, 2025 – Quantum Critical Metals Corp. (TSX.V: LEAP | OTCQB: ATOXF | FSE:
86A1) ("Quantum" or the "Company") is pleased to announce it has received an optical mineralogy report
on two hand samples collected from metric angular blocks on its NMX East Project in Northern Québec.
The report, prepared by PMC Laboratory, documents the mineralogical characteristics of two samples
identified as metamorphosed mafic-ultramafic intrusive rocks. This new information is consistent with
the Company's understanding that its NMX property is related to the Bande du Lac des Montagnes
("BLM") formation. The BLM formation east from the property contain the Ni-PGE mineralization that are
intercepted by Power Metallic Mines Ltd. (TSXV-PNPN).
A recent field visit confirmed a 1 km long, east -west trending amphibolite boulder field with angular,
metric-scale blocks. This trend is associated with a magnetic anomaly. Further exploration will be
conducted to confirm this.
The NMX East Project is in the continuity of the Power Metallic Mines Ltd. (TSXV-PNPN) property near the
Nisk deposit which contains lithium and Ni-PGE. The Nisk deposit is held by Power Metallic and is hosted
within the Bande du Lac des Montagnes ("BLM"), ( a volcano-sedimentary belt that includes paragneiss,
orthogneiss, amphibolite, and mafic volcanic rocks ). The Nisk deposit mineralization is found within an
elongated ultramafic body. This ultramafic intrusion is a layered mafic -ultramafic complex compri sing
pyroxenite, peridotite, and serpentinized dunite. The mineralized zone at the base of the serpentinized
dunite is characterized by semi-massive to massive sulphide accumulations, which are typical of magmatic
Ni-Cu-Co-PGE systems.
Next Steps
It is recommended that Quantum conduct a very high-resolution magnetic and EM-VLF survey on the NMX
East Project with advanced laser magnetometer sensors, which are more accurate and smalle r than
existing magnetic sensors and allow for lower -height flights and the measurement of shorter anomaly
wavelengths that are typically not visible in traditional surveys.

approved the scientific and technical disclosure in this news release.
CEO Marcy Kiesman stated:
"Verification of the presence of mafic-ultramafic rocks at surface on the NMX East Property is great news
for Quantum shareholders. It appears that the rock formation could be associated with the B LM Group
which is step one for ultramafic rock potential in the southern half of the property. We are in the process
of expediting an EM-VLF survey on the property to further investigate Ni-PGE potential at NMX East."
