Further to the company's news releases dated Feb. 3, 2026, and Feb. 24, 2026, the company exercised its right to accelerate the expiry date of certain outstanding warrants issued in connection with previously completed financings, in accordance with the terms of the applicable warrant certificates.

• The LIFE (listed issuer financing exemption) offering completed on Aug. 1, 2025;
• The flow-through financing completed on Aug. 27, 2025.

Pursuant to the acceleration provisions of the warrants, the company provided notice to holders that the expiry date of the warrants would be accelerated to 5 p.m. PDT Vancouver time on March 5, 2026.

David Greenway, chief executive officer of Vanguard Mining, commented: "We are very pleased to see strong participation from our shareholders following the warrant acceleration notice, generating more than $2.5-million in additional capital for the company. With uranium prices remaining strong amid growing global demand for nuclear energy and continued strength in copper and gold markets, we believe the timing of this capital injection is particularly advantageous. The proceeds further strengthen Vanguard's balance sheet and position the company to advance exploration across our portfolio of strategic mineral projects. We appreciate the continued support of our shareholders and believe this participation reflects growing confidence in Vanguard's long-term strategy and the value potential of our global asset base."

Following the accelerated exercise period, 650,000 warrants at an exercise price of 10 cents per share and 817,466 warrants at an exercise price of 22 cents per share expired unexercised.

Currently, 351,238 warrants remain outstanding at an exercise price of 22 cents per share expiring February, 2027.
