Granada Gold raises measured/indicated resources to 890,600 oz Au at 1.73 g/t

Rouyn-Noranda, Quebec – June 23, 2026 – TheNewswire – Granada Gold Mine Inc. (TSXV: GGM) (OTC: GBBFF) (Frankfurt: B6D) (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 Measured and Indicated in-pit and underground Mineral Resources of 890,600 ounces of gold (15,982,000 tonnes grading 1.73 g/t Au), a 64% increase over the 2022 estimate of 543,000 ounces (8,220,000 tonnes at 2.05 g/t Au).  Inferred in-pit and underground Mineral Resources of 865,500 ounces of gold (20,096,000 tonnes grading 1.34 g/t Au), a 90% increase over the 2022 estimate of 456,000 ounces (3,010,000 tonnes at 4.71 g/t Au).  The increase is driven primarily by the substantial rise in the gold price since the 2022 estimate, which supports lower economic cut-off grades (0.25 g/t Au in-pit and 1.4 g/t Au underground, versus 0.55 g/t and 2.5 g/t in 2022), together with updated cost and processing assumptions.  The deposit remains open along strike and at depth.
