Quantum Critical Metals Receives Drilling Permit for NMX East Project

Vancouver, BC — April 2, 2026 — Leads & Copy — Quantum Critical Metals Corp. has received approval from the Ministère des Ressources naturelles et des Forêts for a drilling permit authorizing up to 121 diamond drill holes at its NMX East property, located in the James Bay - Eeyou Istchee region of northern Québec.

The permit allows the Company to conduct systematic exploration drilling across the project area. The program will focus on muscovite-rich pegmatite dykes with the objective of delineating mica hosted critical mineralization, including gallium and rubidium.

Drilling is also planned within an ultramafic rock package on the southern portion of the property to evaluate the potential for nickel polymetallic-mineralization, as outlined in the Company’s news release on August 14th, 2025.

According to Marcy Kiesman, CEO of Quantum, the drill permit from the Ministère des Ressources naturelles et des Forêts is a significant step forward in advancing the NMX East Project. The approval enables Quantum to initiate a comprehensive, multi-phase drilling program designed to systematically define mineralization across both pegmatite and ultramafic packages.

Kiesman added that with growing global demand for critical minerals such as gallium, rubidium and nickel, advancing NMX East supports the company's strategy of developing new sources of strategic metals within stable North American jurisdictions and strengthening Western supply chains.

The 121-drill hole program is expected to be executed in multiple phases over the next two years, allowing the Company to incorporate analytical results from each phase into the design of subsequent campaigns and optimize exploration.

The NMX East Project is located in Québec, and is being explored for its potential to host critical minerals associated with muscovite rich pegmatite systems. The Company believes that continued exploration success at NMX East, combined with its metallurgical advancements in recovery of critical metals from muscovite mica, positions Quantum to play an important role in supporting secure Western supply chains for strategic minerals.

The Company has granted an aggregate of 4,000,000 incentive stock options to certain consultants, directors and officers of the Company in accordance with the Company’s stock option plan. The options are exercisable at a price of $0.07 per common share, valid for a period of three years, and will vest immediately in accordance with the Company’s stock option plan. The grant of options is subject to the acceptance of the TSX Venture Exchange.
