TORONTO, ON / ACCESS Newswire / June 10, 2026 / Jaguar Mining Inc. (the "Company") (TSX:JAG) is pleased to announce significant progress in advancing its 5-Year Exploration Plan with the strategic engagement of two world-class drilling contractors, Major Drilling Group International Inc. ("Major Drilling") and GEOSOL Geologia e Sondagens S.A.("GEOSOL"), to fully operationalize the program at the Chamé and Bahú Corridor in the Iron Quadrangle, Minas Gerais, Brazil. This area is one of the highest priority exploration targets for Jaguar Mining as it is within 1 km of the Santa Isabel Mine underground workings and Processing Plant in the Company's Paciência Complex.

The 5-Year Exploration Plan, first announced in 2025, has already seen early progress, with drilling at the Chamé target commencing in December 2025 through a local contractor (five holes, three of which have assays pending). Building on this foundation, Jaguar is now elevating the initiative to a Tier 1 operational standard by securing the services of Major Drilling and GEOSOL - two industry leaders known for their technical excellence and global experience in mineral exploration.
