GGM:CC - Granada Gold Mine Reviews the Potential of 1 Gram per Tonne Gold in an Open Pit Resource at Minesite

(TheNewswire)

Rouyn Noranda, Q.C., October 15, 2025 – TheNewswire - Granada Gold Mine Inc.(TSXV: GGM) (OTC: GBBFF) (Frankfurt: B6D) (the "Company" or"Granada") With the  current increase in the price of goldthe company is to review the potential for an open pit resource using1 gram per tonne gold at the Granada Minesite.

“The fully permitted, current resource is shovelready.” Commented Frank J Basa, President and CEO, “With 80percent of the 5.5-kilometer mineralized structure open forexploration, there is potential for a significant resourceincrease.”

With over 158,000 metres in over 1,000 holes drilledfrom surface, the mineralized zone is open to depth and on east-weststrike for another 3.5 kilometers. The Granada Gold Mine operated inthe 1930’s as an underground operation at 9-10 grams per tonne fromtwo shafts. The deepest shaft on the mining property, at 498 metresdepth, is shallow compared to other operating mines  on  CadillacBreak where over 1,000-metre-deep production shafts are the norm. Thecurrent proposed development  plan is to operate as an open pit,followed by a higher-grade underground mine.

Notes to resource table above

1. Original assays have been capped at 60 g/t forcalculation of the 1.5 m composites for the estimation of mineralresources.

2. The density to convert volume to tonnage is2.7.

3. Drill hole spacing varies from 6 meters up to 225meters while most of the drill holes are on 30 m cross sections forthe upper 400 m.

4. Gold recoveries are 94.1% for the full mill cyanidationof the whole mineralized material.

5. Assumes gold price of $1,250 U.S/oz and exchange rateof $1.37 CDN/$1 U.S.

6. The open-pit constrained resources were modeled on 10mEx 5mN x 5mZ block size while underground resources below elevation-135 meters were modeled on 10mE x 3mNx 3Mz.  The block models arewithin an envelope.

7. Search ellipsoid estimation ID2 are: 50x50x5,100x100x10, 200x200x15 and 300x300x20 to enable connection of thestructure of the deep holes to the highly drilled package. Saucersdipping north at 47 degrees.

8. Classification: a minimum of 4 holes with 2 compositesper hole for Measured, 3 holes with minimum of 2 composites per holefor Indicated, the remaining Inferred.

9. The database used for this estimate includes drillresults obtained from drill programs in 2009, 2010, 2011, 2012, 2016and 2017, trenches of 2014 and 2015 plus many of the historic holes(1990’s) where sufficiently long sections of the core had beenanalyzed.

10. The statement includes the historical production of51,476 ounces (181,744 sT @ 0.28 oz/sT) from 1930 to 1935.  Theycannot be physically removed in 3D.  However, this amount is nowconsidered to be included in the Measured mineral resources.

11. GoldMinds is not aware of any known environmental,permitting, legal, title-related, taxation, socio-political, marketingor other relevant issues that could materially affect the mineralresource estimate.

The technical information in this news release wasreviewed and approved by Matthew Halliday, P.Geo., Director of GranadaGold Mine Inc., and member of the Ordre des Géologues du Québec, whois a Qualified Person in accordance with National Instrument 43-101.

Further work is necessary to upgrade/verify the May2017 resource estimate using current gold pricing and processingcosts.   The QP has not done sufficient work  and Granada Gold Mineis not treating the resource estimate ascurrent. The reliability and relevance of the historical estimate isnot to be depended upon until the required work is completed.

Mineral Resource Estimate

On August 22, 2022 the Company filed an updated NI43-101 technical report supporting the resource estimate update forthe Granada Gold project (Please see July 6, 2022 newsrelease ) reporting that the Granadadeposit contains an updated mineral resource, at a base case cut-offgrade of 0.55 g/t Au for pit constrained mineral resources within aconceptual pit shell and at a base case cut-off grade of 2.5 g/t forunderground mineral resources within reasonably mineablevolumes, of 543,000 ounces of gold (8,220,000 tonnes at an averagegrade of 2.05 g/t Au) in the Measured and Indicated category, and456,000 ounces of gold (3,010,000 tonnes at an average grade of 4.71g/t Au) in the Inferred category.

About Granada Gold Mine Inc.

Granada Gold Mine Inc. continues to develop and exploreits 100% owned Granada Gold Property near Rouyn-Noranda, Quebec, andis adjacent to the prolific Cadillac Break. The Company owns 14.73square kilometers of land in a combination of mining leases andclaims. The Company is currently undergoing a large drill program with 20,000m out of 120,000m complete.The drills are currently paused to provide the technical team with thenecessary time to evaluate, assimilate existing data and wait forimproved market conditions.

The Granada Shear Zone and the South Shear Zonecontain, based on historical detailed mapping as well as from currentand historical drilling, up to twenty-two mineralized structurestrending east-west over five and a half kilometers. Three of thesestructures were mined historically from four shafts and three openpits. Historical underground grades were 8 to 10 grams per tonne goldfrom two shafts down to 236 m and 498 m with open pit grades from 3.5to 5 grams per tonne gold.

The property includes the former Granada Goldunderground mine which produced more than 50,000 ounces of gold at 10grams per tonne gold in the 1930’s from two shafts before a firedestroyed the surface buildings.  In the 1990s, Granada Resourcesextracted a bulk sample (Pit #1) of 87,311 tonnes grading 5.17 g/t Au. They also extracted a bulk sample (Pit # 2) of 22,095 tonnes grading3.46 g/t Au.
