VANCOUVER, BC, May 12, 2021 - Barsele Minerals Corp. – (TSXV: BME) (the "Company" or "Barsele") is pleased to announce that it has executed a non-binding letter of intent ("LOI") with Agnico Eagle Mines Limited ("Agnico Eagle") to acquire Agnico Eagle's indirect 55% interest in the Barsele Project (the "Proposed Transaction"). The Company currently holds the remaining 45% interest in the Barsele Project and upon completion of the Proposed Transaction, would consolidate control of the Barsele Project. The completion of the Proposed Transaction will be governed by the terms of a definitive agreement to be entered into between Barsele and Agnico Eagle.

Gary Cope, President, CEO and a director of the Company commented, "The opportunity to acquire a 100% controlling interest in the Barsele Project represents a tremendous milestone for Barsele. We plan to significantly increase the drilling activity on the project with the goal of growing the current mineral resource estimates. We are excited to start a new chapter in the development of the Barsele Project and are thankful to our joint venture partner Agnico Eagle for the work we have completed together. We now look forward to having Agnico Eagle as our largest shareholder."

Sean Boyd, Chief Executive Officer of Agnico Eagle commented, "We see Barsele's consolidation of the Barsele Project as a positive outcome for all stakeholders. The monetization of our interest in the Barsele Project will allow Agnico Eagle to focus on the most advanced projects in our exploration and development pipeline, while retaining an interest in the Barsele Project as a significant equity investor and royalty holder. We wish Barsele success as they undertake the next phase of exploration at the project and are confident that they have the required skill set to continue to advance the project."

Guy Gosselin, Senior Vice President, Exploration of Agnico Eagle added, "Agnico Eagle's Swedish exploration team significantly increased the mineral resources and geological understanding of the project, while also building strong social acceptance of the project during this phase of exploration. I am proud and thankful for what our team has accomplished and look forward to closing the Proposed Transaction and watching Barsele's future success at the project."

Terms of the LOI

The LOI provides that the Company and Agnico Eagle will negotiate and enter into a definitive purchase and sale agreement containing customary terms and conditions for a transaction of its nature, whereby Barsele will acquire Agnico Eagle's 55% indirect interest in Gunnarn Mining AB (which holds the Barsele Project). The purchase price payable by Barsele to Agnico Eagle will consist of the following: (i) a cash payment of US$45,000,000 (the "Cash Amount"), with the option, at Barsele's election, to settle a portion of the Cash Amount through a vendor-take-back note; (ii) the issuance of common shares of Barsele such that Agnico Eagle will hold 14.9% of Barsele's common shares upon the closing of the Proposed Transaction (the "Consideration Shares"); (iii) the issuance of warrants exercisable into 6,000,000 common shares of Barsele (the "Warrants"); (iv) a 2% net smelter return royalty on all minerals produced from the Barsele Project (the "NSR"); and (v) a contingent value right with respect to future gold mineral reserves and mineral resources identified at the Barsele Project (the "CVR"). Each Warrant will have a five year term and will entitle Agnico Eagle to purchase one common share of Barsele at an exercise price equal to the greater of: (i) C$1.25, (ii) a 20% premium to the twenty-day volume weighted average price of the Barsele common shares immediately prior to the date of issuance of the Warrant, and (iii) in the event that Barsele issues convertible debt in connection with its financing of the Cash Amount, the conversion price of such convertible debt.

The NSR is expected to contain customary terms and conditions, and Barsele will be able to repurchase 1.0% of the NSR at any time for US$15 million. There is an existing 2.0% net smelter return royalty on the Barsele Project pursuant to an agreement dated June 11, 2015 between Orex Minerals Inc., Gunnarn Mining AB, Agnico Eagle Sweden AB and Agnico Eagle (the "Existing NSR"), which includes a repurchase right for US$5,000,000. The LOI anticipates that the Existing NSR, including the repurchase right, will be assigned and assumed by Barsele at closing of the Proposed Transaction.

Upon closing of the Proposed Transaction, Barsele will grant Agnico Eagle the CVR whereby Barsele will agree to pay Agnico Eagle US$2,500,000 for each additional 1,000,000 ounces of gold mineral reserves and mineral resources identified at the Barsele Project above the Barsele Project's current mineral reserves and mineral resources. The CVR will run with the Barsele Project, but not be payable until the earliest to occur of: (i) a construction decision on the Barsele Project is made, (ii) a change of control of Barsele, or (iii) the 10th anniversary of the closing of the Proposed Transaction. Payments under the CVR will be capped at an aggregate maximum of US$20,000,000 over the CVR's 20-year term. Also, Barsele may satisfy the first US$5,000,000 of any future CVR payments by applying such amount to the repurchase of the Existing NSR rather than payment of the CVR.

Upon closing of the Proposed Transaction, Agnico Eagle and Barsele will enter into an investor rights agreement that will grant Agnico Eagle a participation right in certain future financings to maintain its pro rata or 14.9% (and following the exercise of the warrants, 19.9%), whichever is greater, interest in Barsele, grant Agnico Eagle certain information rights and grant Barsele a placement right in connection with certain proposals by Agnico Eagle to sell Barsele common shares.

Barsele intends to finance all or a portion of the Cash Amount through the issuance of debt and/or equity. Barsele has also agreed that upon closing of the Proposed Transaction, it will have no less than C$5,000,000 in working capital available net of any costs associated with the Proposed Transaction. Barsele has agreed to use its best efforts to complete such financings as soon as practicable.

Barsele and Agnico Eagle have agreed to an exclusivity period ending on July 30, 2021, with a view to settling the definitive documentation for the Proposed Transaction by such date. Such exclusivity period may be extended for an additional 31 days in certain circumstances.

The LOI is non-binding and there can be no assurance that the Proposed Transaction will be completed as proposed or at all. The definitive agreements are expected to contain other representations, warranties, covenants and conditions as are customary for a transaction of this nature. The closing of the Proposed Transaction is subject to the completion of due diligence; the negotiation of the definitive agreement and other final documentation; compliance with applicable laws in Sweden relating to the transfer of the Barsele Project; and corporate and regulatory approvals, including the approval of the TSX Venture Exchange. The TSX Venture Exchange has in no way passed upon the merits of the Proposed Transaction and has neither approved nor disapproved the contents of this news release. The Consideration Shares and Warrants to be issued to Agnico Eagle are expected to be subject to a four-month and one day statutory hold period in accordance with applicable securities law.
