Quantum Critical Metals Confirms Magnetic Anomaly Similar to Nisk Deposit

Vancouver, BC — October 2, 2025 — Leads & Copy — Quantum Critical Metals Corp. has successfully completed an airborne survey on its NMX East Property in Northern Québec, confirming a magnetic anomaly similar to the Nisk deposit.

During September, Quantum (TSX.V: LEAP | OTCQB: ATOXF | FSE: 86A1) completed two airborne surveys at NMX East. The surveys included an electromagnetic (“EM”) very low frequency electromagnetic (“VLF”) and magnetic geophysical survey to validate historical government data and enhance geological targeting, followed by a MAG-TDEM airborne survey to obtain additional high-resolution data. The goal is to better define EM anomalies for improved design of drill targets aimed at Ni-PGE mineralization, similar to that of Power Metallic Mines (TSX-PNPN).

The magnetic anomaly from the first airborne survey prompted an immediate follow-up investigation, requiring a second airborne survey. The second TDEM system survey detected good quality bedrock conductors at greater depth than was previously possible with the VLF-EM technology.

Quantum is planning detailed drill targets for the NMX East and intends to apply for drill permits in the upcoming weeks.

CEO Marcy Kiesman stated that the magnetic anomaly on the NMX East Property is similar in amplitude, strike, shape and size to the anomaly found at the neighboring Nisk deposit.
