Vanstar Mining Resources Files Special Meeting Materials for Friendly Acquisition by IAMGOLD Corporation

Montreal, January 10, 2024 - Vanstar Mining Resources Inc. (TSXV: VSR) (OTCQX: VMNGF) (FSE: 1V8) ("Vanstar", or the "Company") is pleased to announce, further to its news release dated December 5, 2023, that it has mailed its management information circular dated January 4, 2024 (the "Circular") and related proxy materials to holders (the "Vanstar Shareholders") of common shares of Vanstar (the "Vanstar Shares") of record as of December 28, 2023 (the "Record Date") in connection with the special meeting (the "Meeting") of Vanstar Shareholders to be held at 10:00 a.m. (Montréal Time) on February 6, 2024 at 1000 Sherbrooke Street West, Suite 2700, Montréal, Québec H3A3G4.


Special Meeting of Vanstar Shareholders

At the Meeting, Vanstar Shareholders will be asked to consider and vote on a special resolution (the "Arrangement Resolution") approving the Company's previously announced transaction with IAMGold Corporation (NYSE: IAG) (TSX: IMG) ("IAMGOLD") whereby, subject to the terms and conditions of an arrangement agreement between the Company and IAMGOLD dated December 4, 2024 (the "Arrangement Agreement"), IAMGOLD will acquire all of the issued and outstanding Vanstar Shares by way of a court-approved plan of arrangement (the "Transaction"). On December 21, 2023, the Company obtained an interim order of the Superior Court of Québec (the "Court") providing for the calling and holding of the Meeting and other procedural matters related to the Arrangement.


The Consideration

Pursuant to the Transaction, Vanstar's Shareholders will receive 0.2008 of an IAMGOLD common share (each whole common share of IAMGOLD, an "IAMGOLD Share") for each Vanstar Share. Based on the 5-day volume weighted average price of the IAMGOLD Shares on the Toronto Stock Exchange (the "TSX") as of December 1, 2023, the consideration payable by IAMGOLD implies a value of approximately C$0.69 (the "Consideration Value") for each Vanstar Share. In addition, each outstanding common share purchase option of Vanstar (a "Vanstar Option") will be cancelled in exchange for an amount equal to the amount, if any, by which C$0.69 exceeds the exercise price payable under such Vanstar Option by the holder thereof to acquire one Vanstar Share underlying such Vanstar Option, such amount to be paid 50% in cash and 50% in IAMGOLD Shares (with the value of each such IAMGOLD Share deemed to be equal to $3.436 per IAMGOLD Share).

The total consideration payable by IAMGOLD based on the Consideration Value is approximately C$45 million on a fully diluted in-the-money basis. The Consideration Value represents a 74% premium to the 20-day VWAP of the Vanstar Shares on the TSX Venture Exchange ("TSXV") as of December 1, 2023.


Voting Requirements

The Transaction must be approved by at least 66 2/3% of the votes cast by Vanstar Shareholders at the Meeting, and must also be approved by a simple majority of the votes cast by Vanstar Shareholders at the Meeting excluding Vanstar Shares held or controlled by "interested parties" as defined under Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions.

Materials for the Meeting, including the Circular, are also available under Vanstar's profile on SEDAR+ at www.sedarplus.ca and on Vanstar's website at www.vanstarmining.com.


Special Meeting Materials

The Circular contains, among other things, details concerning the Arrangement, the background to and reasons for the favourable recommendation of the Arrangement by the board of directors of the Company, the requirements for the Arrangement to become effective, the procedure for receiving consideration payable under the Arrangement, procedures for voting at the Meeting and other related matters. Vanstar Shareholders are urged to carefully review the Circular and accompanying materials as they contain important information regarding the Arrangement and its consequences to Vanstar Shareholders.

Board Recommendation and Support

After careful consideration, the Vanstar Board of Directors (the "Vanstar Board"), after receiving legal and financial advice, has unanimously determined the Transaction is in the best interests of Vanstar. Accordingly, the Vanstar Board unanimously recommends that the Vanstar Shareholders vote FOR the Arrangement Resolution. Each director of Vanstar intends to vote any and all of his or her Shares FOR the Arrangement Resolution.

All of the directors and senior officers of Vanstar (the "Supporting Shareholders") have entered into voting agreements pursuant to which they have agreed, among other things, to vote their Vanstar Shares in favour of the Arrangement Resolution. As of the date of the Arrangement Agreement, the Supporting Shareholders collectively beneficially owned or exercised control or direction over an aggregate of approximately 11,986,000 Vanstar Shares or Vanstar Options, representing approximately 17.5% of the Vanstar Shares on a fully diluted basis (8.3% of the Vanstar Shares on a non-diluted basis).


Timing

The closing of the Arrangement is subject to the approval of the Vanstar Shareholders, the Court, regulatory and stock exchange approvals and the satisfaction or waiver of certain other customary closing conditions for a transaction such as the Arrangement. Assuming all conditions are satisfied, the Company expects that the closing of the Arrangement will be completed in the first quarter of 2024.
