Jaguar Mining Announces Normal Course Issuer Bid

TORONTO, June 10, 2022 - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG) announces that the Toronto Stock Exchange (the "TSX") has accepted Jaguar's notice to make a normal course issuer bid (the "Bid") to purchase for cancellation up to 3,623,640 common shares in the capital of the Company ("Common Shares") in total, being 5% of the issued and outstanding Common Shares as at the date of Jaguar's notice to the TSX, to be transacted through the facilities of the TSX. The actual number of Common Shares that may be purchased pursuant to the Bid will be determined by management of the Company ("Management"). The Bid will commence on June 15, 2022 and will terminate on June 14, 2023, or such earlier time as the Bid is completed or terminated at the option of Jaguar.

Purchases pursuant to the Bid will be made by Pollitt & Co. Inc. on behalf of the Company. Decisions regarding the timing of purchases under the Bid will be determined by Management based on market conditions, share price and other factors. Management may elect to not purchase any Common Shares under the Bid, or may elect to suspend or discontinue the Bid at any time. Any purchases pursuant to the Bid will be financed from the working capital of Jaguar.

In accordance with the rules of the TSX governing normal course issuer bids, the total number of Common Shares the Company is permitted to purchase is subject to a daily purchase limit of 22,395 Common Shares, representing 25% of the average daily trading volume of Common Shares on the TSX calculated for the six-month period ended May 31, 2022, being approximately 89,581 Common Shares. However, the Company may make one block purchase per calendar week which exceeds the daily repurchase restriction. The price that Jaguar will pay for any Common Shares under the Bid will be the prevailing market price on the TSX at the time of such purchase.

The Board of Directors of Jaguar believes that the underlying value of the Company may not be accurately reflected at times in the market price of the Common Shares. Accordingly, the purpose of the Bid is to enhance long-term shareholder value through the purchase and cancellation of Common Shares at a discount to the underlying value of the Company. Furthermore, the purchases by Jaguar will help mitigate the dilutive effects of any future potential issuances of additional Common Shares as consideration for capital raises, joint ventures or asset acquisitions.

A copy of the Form 12 (Notice of Intention to Make a Normal Course Issuer Bid) filed with the TSX in connection with the Bid can be obtained from the Company upon request without charge.

As of the close of business on June 3, 2022 (being the date of Jaguar's aforementioned notice to the TSX regarding the Bid), the Company had 72,472,809 Common Shares issued and outstanding.
