Granada Gold Mine Advances On-Site Processing Authorization for Gravity Concentration at Granada Gold ProjectMay 26, 2026 9:01 AM
NewsfileCompany 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 external polishing pond, and a flocculation and precipitation treatment stage designed to manage suspended solids and dissolved metals. The facility is designed as a closed-loop system with no anticipated water discharge to the surrounding environment.The residue from the concentration process is expected to be non-deleterious and to hold resale value as a construction aggregate, consisting essentially of crushed rock that has undergone physical separation only. The Company intends to characterize the residue in consultation with the MELCCFP to determine the appropriate regulatory classification and requirements. The concentrate produced on site is intended for further metallurgical evaluation and recovery, including through the Company's ongoing optimization work with SGS Lakefield.The on-site gravity concentration step is complementary to the ore sorting results announced on April 28, 2026, which demonstrated a 2.7x gold-grade uplift with 88 percent gold recovery using XRT sorting. When combined in sequence, ore sorting followed by gravity concentration, these pre-concentration technologies have the potential to significantly reduce the volume of material requiring final processing, with direct implications for capital intensity, operating cost per recovered ounce, and the economics of a stand-alone processing operation at Granada."This authorization modification is the bridge between an exploration project with a permit and a project with processing infrastructure on the ground," stated Frank J. Basa, P.Eng. Ontario, President and CEO. "Our existing authorization already covers extraction of mineralization. Adding gravity concentration on site means we can begin producing a gold-bearing concentrate from our own property using proven, low-capital-intensity technology that generates a residue we expect to be non-deleterious, essentially crushed rock with potential resale value as construction aggregate. When you combine that with our ore sorting results, which reject two-thirds of the mass before it ever reaches the gravity concentration process, and the mineral resource update now underway with GoldMinds, the picture that emerges is a project where the path from permitted extraction to revenue has been materially shortened."EEC Engagement and TimelineEEC is a Québec-based environmental engineering company, with offices across Canada including in Rouyn-Noranda. EEC has supported environmental authorization processes for major Québec mining projects. The firm was recommended by the Company's advisors for its direct experience in environmental authorization applications for mining and industrial projects in the Abitibi region.The scope of work covers the consolidation and filing of the authorization modification application with the MELCCFP, including mandatory activity and impact forms, a geolocation file, and an accompanying report providing context for the requested modification. The application will require engineering design packages for both the concentration process and the water treatment circuit, which will be provided by an engineering firm to be selected by the Company. EEC will provide limited support in the identification of requirements for the engineering services provider. A preliminary version of the application is expected by September 2026, with the final version targeted for October 2026, subject to the timely provision of engineering design packages and other client-furnished documentation.Development Framework and Processing StrategyThe on-site processing authorization advances in parallel with the mineral resource estimate update being prepared by GoldMinds Geoservices Inc. under the direction of Claude Duplessis, P.Eng. (OIQ #45523). The Company is evaluating the scope of a Preliminary Economic Assessment to complement the updated MRE, which would assess development scenarios centred on production, including both toll milling to a third-party processing facility in the Abitibi region and the option of on-site processing at the Granada property. The authorization modification announced today would establish the regulatory foundation for the on-site processing scenario and, if approved, provide the Company with the flexibility to pursue either pathway, or a combination of both, based on the economic analysis to follow.The authorization modification builds on the Company's existing Certificate of Authorization for mineralized material extraction, the ore sorting results announced on April 28, 2026, and the mineral resource estimate update currently underway. Together, these workstreams are intended to establish the technical and economic foundation for a production decision. The Company continues to evaluate project financing alternatives, including potential non-dilutive structures such as offtake agreements and prepayment facilities.Qualified PersonThe technical information in this news release was reviewed and approved by Matthew Halliday, P.Geo., Director of Granada Gold Mine Inc. and member of the Ordre des Géologues du Québec, who is a Qualified Person in accordance with NI 43-101.Mineral Resource EstimateOn August 22, 2022 the Company filed an updated NI 43-101 technical report supporting the resource estimate update for the Granada Gold project (Please see July 6, 2022 news release) reporting that the Granada deposit contains an updated mineral resource, at a base case cut-off grade of 0.55 g/t Au for pit constrained mineral resources within a conceptual pit shell and at a base case cut-off grade of 2.5 g/t for underground mineral resources within reasonably mineable volumes, of 543,000 ounces of gold (8,220,000 tonnes at an average grade of 2.05 g/t Au) in the Measured and Indicated category, and 456,000 ounces of gold (3,010,000 tonnes at an average grade of 4.71 g/t Au) in the Inferred category.

The Company owns 14.73 square kilometres of land in a combination of mining leases and claims. The Company is currently advancing the Granada Gold Project through an updated mineral resource estimate and preliminary economic assessment, with drilling planned to target both lateral extensions and depth expansion of the existing mineral resource.The Granada Shear Zone and the South Shear Zone contain, based on historical detailed mapping as well as from current and historical drilling, up to twenty-two mineralized structures trending east-west over five and a half kilometres. Three of these structures were mined historically from four shafts and three open pits. Historical underground grades were 8 to 10 grams per tonne gold from two shafts down to 236 m and 498 m with open pit grades from 3.5 to 5 grams per tonne gold (43-101 reference).The property includes the former Granada Gold underground mine which produced more than 50,000 ounces of gold at 10 grams per tonne gold in the 1930's from two shafts before a fire destroyed the surface buildings. In the 1990s, Granada Resources extracted 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 grading 3.46 g/t Au.

Granada Gold Mine Engages GoldMinds Geoservices for Mineral Resource Estimate Update Reflecting Current Gold PricingMay 19, 2026 9:01 AM
NewsfileUpdated MRE to Evaluate Expanded Open-Pit Gold Potential Using various cut-off gold gradesRouyn Noranda, Quebec--(Newsfile Corp. - May 19, 2026) - Granada Gold Mine Inc. (TSXV: GGM) (OTC Pink: GBBFF) (FSE: B6D) (the "Company" or "Granada") is pleased to announce the engagement of GoldMinds Geoservices Inc. ("GoldMinds") to complete an updated NI 43-101 compliant Mineral Resource Estimate ("MRE") for the Granada Gold Project located near Rouyn-Noranda, Québec. The MRE will be prepared under the direction of Claude Duplessis, P.Eng. (OIQ #45523), a Qualified Person as defined under NI 43-101.The MRE update will incorporate all available drilling and exploration data accumulated since the last resource update and will evaluate the deposit using various cut-off grades for pit-constrained mineral resources. This approach builds on the methodology employed by GoldMinds in its May 2017 NI 43-101 Technical Report. That report, which constitutes a historical mineral resource estimate, reported pit-constrained Measured resources of 17,068,500 tonnes at 1.14 g/t Au for 625,000 ounces and Indicated resources of 4,507,000 tonnes at 1.26 g/t Au for 182,700 ounces (combined Measured and Indicated of 21,575,500 tonnes at 1.16 g/t Au for 807,700 ounces), plus Inferred underground resources of 10,386,500 tonnes at 4.56 g/t Au for 1,523,800 ounces. With gold now trading near US$4,700 per ounce, compared to the US$1,250 per ounce price assumption used in the 2017 estimate, the Company believes a re-evaluation of the deposit at current price levels is warranted and could demonstrate a materially larger economic resource envelope. Inferred mineral resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically, and it cannot be assumed that all or any part of an Inferred mineral resource will be upgraded to a higher category.The study will also consider the integration of ore sorting technology, following the Company's recent independent test program at the Saskatchewan Research Council, which demonstrated a 2.7x gold grade uplift with 88 percent recovery (see news release dated April 28, 2026)."The original author of the 2017 historical resource estimate is now updating his own work with the benefit of additional drilling data, a structural reinterpretation of the deposit, and a gold price environment that no longer requires us to apologise for a 0.39 gram per tonne cut-off," stated Frank J. Basa, P.Eng. Ontario, President and CEO. "We engaged GoldMinds because Claude Duplessis and his team bring direct continuity with the geological model and block model they built for this deposit."MRE Scope of WorkThe GoldMinds engagement covers a two-phase scope of work:Mineral Resource Estimate Update will include a mass model update, updated pit-constrained and underground mineable shape optimization, and preparation of an NI 43-101 compliant technical report. The update will incorporate data from all drill programs through 2025, including the 158,000+ metres drilled from surface across more than 1,000 holes, as well as the structural interpretation completed by Ronacher McKenzie Geoscience Inc. (see news releases dated November 17, 2025 and January 8, 2026).Historical Mineral Resource Estimate and Gold Price ContextThe following table summarizes the May 2017 historical mineral resource estimate prepared by GoldMinds Geoservices Inc. (the "2017 Historical Estimate") using a pit-constrained methodology with a 0.39 g/t Au cut-off (US$1,250/oz gold, CDN/US exchange rate of 1.37) for pit-constrained M&I resources and a 1.5 g/t Au cut-off ($81.99 per tonne) for underground Inferred resources. Key parameters include: a density of 2.7 to convert volume to tonnage; original assays capped at 60 g/t Au for compositing; gold recovery of 94.1% for full mill cyanidation; search ellipsoid estimation ID2 of 50x50x5, 100x100x10, 200x200x15 and 300x300x20; open-pit constrained resources modelled on 10mE x 5mN x 5mZ block size and underground resources on 10mE x 3mN x 3mZ. Classification criteria required a minimum of 4 holes with 2 composites per hole for Measured, 3 holes with 2 composites per hole for Indicated, with the remainder classified as Inferred. The resource categories used in the 2017 Historical Estimate are consistent with the CIM Definition Standards on Mineral Resources and Mineral Reserves (2014) as adopted by CIM Council. The 2017 Historical Estimate is considered relevant to the planned MRE update because it was prepared by the same Qualified Person (Claude Duplessis, P.Eng.) using a methodology, database, and block model that will form the foundation of the updated estimate; however, the Qualified Person has not done sufficient work to classify the 2017 Historical Estimate as a current mineral resource, and the Company is not treating the 2017 Historical Estimate as a current mineral resource. The work required to upgrade and verify the 2017 Historical Estimate as a current mineral resource includes incorporation of all post-2017 drill data, updated geological and structural interpretation, re-optimization of pit shells and underground mineable shapes using current economic parameters, and preparation of a new NI 43-101 compliant technical report, which is the subject of the GoldMinds engagement announced herein:
