Midnight Sun Mining Corp. has appointed a chairman of the board, and has nominated two new, highly accomplished, independent candidates for election at the company's upcoming annual general meeting, scheduled for Dec. 4, 2026. Bringing extensive experience in major mine development and operations, capital markets, and corporate governance, the nominees add significant expertise to the board as Midnight Sun advances its flagship Dumbwa copper deposit.

Appointment of chairman of the board

Brett A. Richards has been appointed as chairman of the board, effective immediately.

Mr. Richards has served as a director of Midnight Sun since August, 2017, and brings more than 35 years of experience in the mining and metals industry, including three decades focused primarily on Africa. His extensive experience spans the full mining life cycle, from exploration and mine development through construction, operations, and strategic exits.

The appointment of an independent chairman reinforces Midnight Sun's commitment to strong corporate governance and independent board oversight, while leveraging extensive mining industry leadership.

New independent director nominees

Two new independent director nominees, Andrew Neale and Caroline Cathcart, will be included on the board slate at the upcoming annual general meeting, joining current independent board members Mr. Richards, Rick Mazur and Wayne Moorhouse, along with company president and chief executive officer Al Fabbro. Together, the nominees bring significant and complementary experience to the board, strengthening the overall slate with specific expertise in the areas of public company governance, capital markets and deposit development.

Mr. Neale is currently chief executive officer of CopAur Minerals Inc. (TSX Venture Exchange: CPAU), which is advancing the Kinsley gold project in Nevada. He holds a master of applied science degree from the University of Alberta.

Ms. Cathcart is a senior capital markets executive with more than 30 years of experience in resource-sector investing, portfolio management, corporate governance and regulatory oversight.

As vice-president and portfolio manager at Goodman & Company, Investment Counsel Inc., she worked alongside prominent resource investor Ned Goodman, leading market strategy and research initiatives.

Advanced notice policy

The company also announces the adoption by its board of directors of an advanced notice policy regarding the election of directors.

The purpose of the advanced notice policy is to provide a clear process for the shareholders, directors and management to follow when nominating directors of the company. Such a policy will ensure that shareholders receive adequate notice of director nominations and sufficient information regarding all director nominees and to allow shareholders to register an informed vote after having been afforded reasonable time for appropriate deliberation.

The advanced notice policy sets a deadline by which director nominations must be submitted to the company prior to any annual general or special meeting of the shareholders and also sets out the required information that must be included in the notice to the company. No person will be eligible for election as a director of the company unless nominated in accordance with the advanced notice policy.

In the case of an annual general meeting of the shareholders, notice to the company must be made not less than 30 days prior to the date of the annual general meeting. If the annual general meeting is being held on a date that is less than 50 days following the date on which the first public announcement of the meeting was made, notice may be made not later than the close of business on the 10th day following such public announcement.

In the case of a special meeting of shareholders (which is not also an annual general meeting) called for the purpose of electing directors, notice to the company must be made not later than the close of business on the 15th day following the day on which the first public announcement of the date of the special meeting was made. Notwithstanding the foregoing, the board of directors may, in its sole discretion, waive any requirement of the advanced notice policy.

The advanced notice policy is now in effect and will apply in connection with the shareholders' meeting. The company intends to seek shareholder approval by ordinary resolution of amendments to the company's articles to include advanced notice provisions with respect to the election of directors which contain substantially the same terms as the advanced notice policy. If the advance notice amendments are not approved by ordinary resolution, then the advanced notice policy and the advance notice amendments will terminate and be void and of no further force or effect following the later of the conclusion of the shareholders' meeting or any adjournment thereof.

A full description of the advance notice amendments will be contained in the information circular to be prepared for the shareholders' meeting and mailed to the company's shareholders. A copy of the advanced notice policy will be filed on SEDAR+ under the company's profile.

About Midnight Sun Mining Corp.

Midnight Sun is rapidly advancing the Solwezi copper project, with a focus on our flagship Dumbwa copper deposit. The project is located near the town of Solwezi in the heart of the Zambia-Congo Copperbelt, the world's second-largest copper-producing region. This prolific mining district is renowned for hosting multiple major copper deposits, and benefits from excellent infrastructure, an established mining work force and a long history of successful production.

The Solwezi copper project is surrounded by producing copper mines, including the geologically similar Lumwana mine to the west and First Quantum's Kansanshi mine -- Africa's largest integrated metallurgical processing facility, approximately six kilometres east of the company's recently announced Kazhiba oxide resource. This highly favourable location highlights the district-scale potential of Midnight Sun's land package.

The Dumbwa copper deposit underlays a robust 20-kilometre copper-in-soil anomaly, and continuing drilling has demonstrated strong geological similarities to the nearby Lumwana mine, underscoring the potential scale of this newly identified copper system.

Led by an experienced geological team with a proven record of major discoveries in the Zambia-Congo Copperbelt and globally, Midnight Sun's goal is to delineate Zambia's next-generational copper deposit.

We seek Safe Harbor.
