Jaguar Mining Completes Filing of Annual Information Form

TORONTO, April 21, 2020 - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG) announces that the Company has filed its annual information form for the year ended December 31, 2019 (the "AIF"), which adds additional disclosure to the December 31, 2019 annual financial statements and management discussion and analysis already filed by the Company on March 30, 2020 and available on SEDAR.

Jaguar is normally required under Section 6.2 of National Instrument 51?102 - Continuous Disclosure Requirements to file its AIF by the 90^th day after the Company's most recently completed financial year. However, as previously disclosed in the Company's news release dated March 30, 2020, due to the business restrictions and operational challenges resulting from the outbreak of the COVID-19 pandemic, the Company elected to rely on the temporary blanket relief published by Canadian securities regulators to file its AIF.

As required by Ontario Instrument 51-502 - Temporary Exemption from Certain Corporate Finance Requirements ("Ontario Instrument 51-502"), Jaguar confirms that there have been no material business developments since March 30, 2020 (being the date of the Company's last news release required by Ontario Instrument 51-502).
