Granada Gold Announces 64% Increase in Measured and Indicated Mineral Resources to 890,600 oz Au (15,982,000 Tonnes at 1.73 g/t Au) and 90% Increase in Inferred Mineral Resources to 865,500 oz Au (20,096,000 Tonnes at 1.34 g/t Au)

About this update from Granada Gold Mine Inc.

Rouyn Noranda, Quebec--(Newsfile Corp. - June 23, 2026) - Granada Gold Mine Inc. (TSXV: GGM) (OTC Pink: GBBFF) (FSE: B6DA) (the "Company" or "Granada") is pleased to provide an updated Mineral Resource Estimate (the "2026 MRE") for its 100%-owned Granada Gold Project, a past-producing property located adjacent to the prolific Cadillac Break in the Abitibi greenstone belt near Rouyn-Noranda, Quebec, and within trucking distance of several operating gold mines and mills in northwestern Quebec. The 2026 MRE combines in-pit (open-pit-constrained) and underground Mineral Resources. It re-evaluates the independent SGS Canada Inc. block model that supported the Company's 2022 estimate, applying updated economic parameters, principally the current gold price, revised cut-off grades, and updated processing and site assumptions, to reflect today's gold price environment. HIGHLIGHTS Table 1 – Granada Gold Project 2026 Mineral Resource Estimate   Pit-constrained resources reported at a 0.25 g/t Au cut-off; underground resources at a 1.4 g/t Au cut-off. Measured and Indicated are reported exclusive of Inferred. See notes below. Compared with the Company's most recent Mineral Resource Estimate of record, prepared by SGS Canada Inc. (Yann Camus, P.Eng.) with an effective date of June 23, 2022, and reporting 543,000 ounces Measured and Indicated (8,220,000 tonnes at 2.05 g/t Au) and 456,000 ounces Inferred (3,010,000 tonnes at 4.71 g/t Au), the 2026 MRE represents a 64% increase in Measured and Indicated contained gold and a 90% increase in Inferred contained gold. As expected, when a deposit is re-evaluated at a materially higher gold price, the average grade of the reported resource is lower than in 2022, because lower-grade material that was previously below the cut-off grades applied in 2022 is captured within the reported resource at the lower cut-off grades applied in 2026. The contained-ounce increase reflects the larger tonnage captured at the lower cut-off grades, consistent with how mineral resources across the sector are being re-stated in the current gold-price environment. Table 2 – Comparison with the 2022 Mineral Resource Estimate   "This update re-evaluates the Granada deposit at current prices and reflects the work we have done to refine the geological model. Measured and indicated ounces are up 64...
