Toronto, Canada, June 5, 2019 - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG) announced today the voting results from its annual general and special meeting of shareholders held on June 4, 2019 (the “Meeting”).

Election of Directors

Each of the nominees for election as directors listed in the Company’s management information circular dated April 22, 2019 were elected as directors of the Company for the ensuing year or until their successors are elected or appointed.

The voting results for the election of directors were as follows:

Despite such elections, since Messrs. Reeser and Falconer received a greater number of votes “WITHHELD” than votes “FOR” at the Meeting, each of them has tendered a resignation to the Chairman of the board of directors (the “Board”), in accordance with the Company’s majority voting policy.

These voting results indicate there is a desire for change at Jaguar. According to the Company’s majority voting policy, the Governance, Compensation and Nominating Committee is supposed to consider and make recommendations to the Board on any offers of resignation made pursuant to the majority voting policy (the “Review”). However, since Messrs. Reeser and Falconer are members of the Governance, Compensation and Nominating Committee, it is expected that the Board will create a special committee (the “Special Committee”) to complete the Review. It is anticipated that the Special Committee will be comprised of Messrs. Weng, Miraglia and Getz. In order to fully undertake the Review and act on the message received from shareholders at the Meeting, the Special Committee will also complete a thorough review of the Company’s circumstances, operating and financial performance, corporate governance and emerging opportunities. The Company will utilize this opportunity to initiate positive change and progressive development at Jaguar in a manner that is in the best interest of the Company while considering all stakeholders and prioritizing a desire to maximize shareholder value. This is expected to involve, among other things:

• completing the hiring of a new, permanent Chief Executive Officer with extensive knowledge, capabilities and experience in mining operations;

• developing and implementing a plan for modernizing the mining and processing infrastructure as well as equipment of the Company;

• optimizing the Company’s operations in order to increase ore processing and gold production while significantly reducing the expenses per tonne processed and per ounce of gold produced; and

• financing this change in a manner that will strengthen the Company’s balance sheet while maximizing expected shareholder returns and minimizing debt.

Therefore, the Special Committee will consider the offers of resignation and also the candidates who are best suited to fill any vacancies on the Board. Taking into account the recommendations of the Special Committee, the Board will make its decision on whether to accept these offers of resignation and will announce it in a subsequent press release as soon as practical and in any event, within 90 days following the Meeting.
