Granada Gold advances gravity concentration facility

Rouyn-Noranda, Quebec – June 30, 2026 – TheNewswire – Granada Gold Mine Inc. (TSXV: GGM) (OTC: GBBFF) (Frankfurt: B6D) (the “Company” or “Granada”) is pleased to report that representatives of its independent environmental engineering consultant have completed a site visit to the Granada Gold Project near Rouyn-Noranda, Québec. The visit assessed candidate locations for the proposed on-site gravity concentration facility and advanced preparation of the Company’s Authorization Modification Request under Article 30 of the Québec Environment Quality Act, which would add on-site gravity concentration to the Company’s existing Certificate of Authorization (see news release dated May 26, 2026). On-Site Gravity Concentration and Water Management The proposed facility is designed to upgrade mineralized material on site through a conventional gravity concentration circuit, housed within a dome structure laid on a crushed-rock-and-membrane foundation and intended for seasonal operation, as described in the Company’s May 26, 2026 news release.

Following extraction and ore sorting, mineralized material is reduced in size and classified, then passed through successive stages of gravity concentration that separate gold-bearing particles from lighter material using water and centrifugal force, without chemical reagents in the concentration step. The circuit is intended to yield a gold-bearing concentrate for further metallurgical evaluation and recovery, building on the Company’s prior metallurgical test work at SGS Lakefield, and a barren stream that reports to the water management circuit. By upgrading grade at the mine, the facility is designed to reduce the volume of material that must be hauled off the property for final processing.
