Quantum Critical Metals Confirms Promising Magnetic Anomaly at NMX East Project Through Advanced Airborne Surveys

Quantum Critical Metals Corp. has successfully completed a second airborne survey at its NMX East Property in Northern Quebec, building on initial findings that revealed a magnetic anomaly comparable to the established Nisk deposit. The company conducted two separate airborne surveys during September 2025, beginning with an electromagnetic, very low frequency electromagnetic, and magnetic geophysical survey to validate historical government data and enhance geological targeting.

The initial survey results prompted immediate follow-up investigation, leading to a second MAG-TDEM (magnetic-time domain electromagnetic) airborne survey. This advanced survey technology detected good quality bedrock conductors at greater depths than was previously possible with VLF-EM technology, providing higher resolution data for improved design of drill targets aimed at nickel and platinum group element mineralization similar to that of neighboring Power Metallic Mines.

The magnetic anomaly identified on Quantum's NMX East Property shows similarity in amplitude, strike, shape, and size to the anomaly found at the Nisk deposit, based on public results from another MAG-TDEM survey performed over Nisk as documented in the technical report by Dube (2023) available at https://gq.mines.gouv.qc.ca/documents/EXAMINE/GM73786/GM73786RAP001.pdf. This correlation is significant because nickel and PGE are commonly searched for using airborne and magnetic surveys to locate rock types of interest, as demonstrated in recent research by Vallee et al. (2024) published at https://doi.org/10.3390/min14121286.

The NMX East Property's location in Quebec's James Bay region positions the company in an area with known sources of lithium, nickel, and platinum group elements. CEO Marcy Kiesman emphasized the significance of these findings, noting that the magnetic anomaly's similarity to the Nisk deposit is encouraging for shareholders, particularly given the substantial activity occurring throughout the surrounding James Bay area during the current exploration season.

Quantum is now planning detailed drill targets for the NMX East property and intends to apply for drill permits in the coming weeks. The successful completion of these airborne surveys represents an important step forward in the company's exploration strategy, potentially accelerating the timeline for identifying viable mineral deposits in this promising geological setting. The use of advanced TDEM technology has provided deeper subsurface insights that could significantly enhance the efficiency and success rate of future drilling operations.

The confirmation of magnetic anomalies similar to established deposits has broader implications for the critical metals exploration industry, demonstrating how advanced geophysical techniques can improve targeting accuracy and reduce exploration risk. As global demand for nickel and platinum group elements continues to grow, particularly for applications in clean energy technologies and industrial processes, successful exploration in regions like James Bay could contribute to securing stable supply chains for these essential materials.
