TORONTO, ON / ACCESS Newswire / October 7, 2025 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG) today announced, further to its news release dated September 29, 2025, an updated structure for its "bought deal" private placement (the "Offering") of common shares (each, an "Offered Share"). Specifically, the Offering will include a significant subscription from existing major shareholder, Eric Sprott, for 1,818,812 Offered Shares at a price of C$5.50 per Offered Share (the "Offering Price") for gross proceeds of approximately C$10.0 million. The Offered Shares issued to Mr. Sprott will not be issued pursuant to the LIFE Exemption (as defined below) but rather, will be subject to a hold period in accordance with applicable Canadian securities law, expiring four months and one day following the Closing Date (as defined below).

Red Cloud Securities Inc. ("Red Cloud") is acting as lead underwriter and sole bookrunner on behalf of a syndicate of underwriters (the "Underwriters") under the Offering, pursuant to which the Underwriters have agreed to purchase for resale 4,545,455 Offered Shares for gross proceeds of C$25,000,002.50. In addition, the Company has granted to the Underwriters an option, exercisable up to 48 hours prior to the Closing Date, to purchase for resale up to an additional 545,455 Offered Shares at the Offering Price for additional gross proceeds of up to C$3,000,002.50.

The Company intends to use the net proceeds of the Offering to fund the restart of the Turmalina Mine at the Company's MTL Complex, exploration activities across the Company's properties, as well as general working capital and corporate purposes, as is more fully described in the Offering Document (as defined below). This financing underscores Jaguar's commitment to unlocking the full potential of its Brazilian assets and reinforcing its standing as a responsible and growing gold producer in the region.

Except to the extent that any Offered Shares are sold to purchasers resident in jurisdictions outside of Canada, such as the United States, the Offered Shares sold to purchasers other than Mr. Sprott, under the Offering, will be sold by way of the "listed issuer financing" exemption under Part 5A of National Instrument 45-106 - Prospectus Exemptions, as amended by Coordinated Blanket Order 45-935 - Exemptions from Certain Conditions of the Listed Issuer Financing Exemption(the "LIFE Exemption"). The Offered Shares sold by way of the LIFE Exemption are expected to be immediately freely tradeable in accordance with applicable Canadian securities legislation.
