MAGNA MINING ANNOUNCES APPOINTMENT OF GREG HUFFMAN TO SENIOR VICE PRESIDENT, CAPITAL MARKETS

Magna Mining Inc. has appointed Greg Huffman as senior vice-president, capital markets, effective Sept. 17, 2025.

Magna Mining chief executive officer Jason Jessup stated: "We are delighted that Greg has agreed to join Magna.

Over the past year, he has served as a strategic adviser to Magna. His extensive experience in capital markets, coupled with his knowledge of our projects and operations, will be invaluable as our company enters our next phase of growth."

Mr. Huffman held the position of chief executive officer, president and director of Nuclear Fuels Inc until September, 2025, when the company was acquired. His extensive career has spanned positions in institutional mining equity sales, fund management and mining equity research, and he held the position of global head of mining sales at Canaccord Genuity from 2016 until June, 2024.

Grants of security-based compensation

Magna also announces that 800,000 options to purchase an equivalent number of common shares of the company were granted to certain officers, as follows:

• Eight hundred thousand options were granted, effective Sept. 17, 2025, at a strike price of $2.69, but vesting only upon the fulfilment of certain time and share price performance conditions, such that certain extended periods of time must elapse and the company's share price must increase to and remain at certain levels for an extended number of consecutive trade days before the options will vest (the entirety of the options vesting after 36 months from the effective date of grant but only if the company's share price has been at least $5 for 20 consecutive trade days), all with a five-year term to expiry -- such time and share price performance conditions aligning the vesting of the options with sustainable shareholder return.

Such grants have been made under the company's omnibus equity incentive plan, which was approved by the shareholders of the company on June 26, 2025. The omnibus plan is a rolling 10-per-cent plan and provides for the grant of options, restricted share units, performance share units and deferred share units. The aggregate number of common shares reserved for issuance pursuant to the omnibus plan and all other security-based compensation arrangements of the company, at any time, must not exceed 10 per cent of the company's total issued and outstanding common shares.

For additional information regarding the omnibus plan, please refer to the management information circular of the company dated May 26, 2025, which is accessible on SEDAR+under the company's issuer profile. The omnibus plan has received conditional acceptance from the TSX Venture Exchange.
