Quantum Completes Initial Airborne Survey at NMX East Project in Québec

Follow Up MAG-TDEM Survey Planned to Advance Nickel-PGE Drill Targeting

Vancouver, BC – September 22, 2025 – Quantum Critical Metals Corp. (TSX.V: LEAP | OTCQB: ATOXF |

FSE: 86A1) ("Quantum" or the "Company") is pleased to announce that further to the news of August 14th,

2025 the Company has successfully completed an electro magnetic (“EM”) very low frequency

electromagnetic (“VLF”) and magnetic geophysical survey at its wholly owned NMX East Project in

Northern Québec.

The survey was designed to validate historical government data and enhance geological targeting at NMX

East, which is located in the same region as Power Metallic Mines Ltd. (TSXV-PNPN) Nisk deposit which is

a known source of lithium, nickel and platinum group elements (“PGE”).

Nickel and PGE are commonly searched for with airborne and magnetic surveys to help locate the rock

types of interest (Vallée et al. 2024).

Next Steps: Enhanced Targeting Through Follow Up MAG TDEM Survey

Based on favourable results, Quantum plans to undertake a follow up high resolution MAG-TDEM (time

domain elect romagnetic) survey. This advanced geophysi cal work is expected to si gnificantly improve

subsurface modeling and help refine high priority drill targets for Ni- PGE mineralization. Additional

information and reports on the air surveys will be released as they become available.

CEO Marcy Kiesman stated:

"In August we confirmed the presence of mafic-ultramafic rocks at surface, and the airborne data further

supports the potential for nickel and PGE targets at NMX East. These early results are encouraging as we

work to define drill ready targets in this highly favourable prospective region.”

Options

The Company also announces the issuance of 4,000,000 stock options to consultants and directors. The

options are exercis able at $0.15 per share for a p eriod of five years , aligning with long -term incentives

with shareholder value creation.
