Company Engages Environmental Engineering Company to Prepare Authorization Modification Under Quebec's Environment Quality Act, on-site Gravity Concentration of Bulk SampleRouyn Noranda, Quebec--(Newsfile Corp. - May 26, 2026) - Granada Gold Mine Inc. (TSXV: GGM) (OTC Pink: GBBFF) (FSE: B6D) (the "Company" or "Granada") is pleased to announce the engagement of an Environmental Engineering Company ("EEC") to prepare and file an Authorization Modification Request under Article 30 of the Québec Environment Quality Act ("EQA") to add on-site gravity concentration to the Company's existing Certificate of Authorization for the Granada Gold Project located near Rouyn-Noranda, Québec. The application will seek to amend the Company's current authorization, which permits the mining of the mineralized material, to include on-site gravity processing technology housed within a dedicated facility at the mine site.The authorization modification represents the first formal infrastructure permitting step in the Company's Rolling Start development pathway and establishes the regulatory foundation for on-site processing at Granada. The Company currently holds a Certificate of Authorization from the Québec MELCCFP (formerly MDDELCC) authorizing the partial exploitation of the Granada Gold site, covering four open pits, two waste rock stockpiles, one mineralized material stockpile. The existing authorization, originally issued in 2016, covers mining and extraction infrastructure only. The proposed modification would add a processing facility to the permitted site, enabling the Company to evaluate on-site gravity concentration as a production pathway alongside toll milling alternatives. The Company is also advancing a mineral resource estimate update with GoldMinds Geoservices Inc. (see news release dated May 19, 2026).On-Site Processing Facility and Authorization ScopeThe proposed on-site facility will consist of a dome structure laid on a crushed-rock-and-membrane foundation, intended for seasonal operation of gravity concentrators. Gravity-based mineral separation technology that upgrades ore through physical processes (density-driven particle separation using water and centrifugal force) without the use of chemical reagents in the concentration step. The concentration process will be accompanied by a water treatment circuit comprising a settling pond within the dome, an ex...
