Vancouver, June 11, 2026 - Maple Gold Mines Ltd. (TSXV: MGM) (OTCQX: MGMLF) (FSE: M3G0) ("Maple Gold" or the "Company") today announced the filing of a technical report in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") on its 100%-owned Douay Gold Project ("Douay") and Joutel Gold Project ("Joutel") (together, "Douay/Joutel" or the "Project") located along the Casa Berardi-Douay Gold Trend in Québec, Canada. The technical report, titled "NI 43-101 Technical Report, Douay/Joutel Gold Project, Northwestern Quebec, Canada" and dated June 11, 2026 (effective date of April 24, 2026) (the "Technical Report"), was prepared by Mr. Denis Decharte, P.Eng., of SLR Consulting (Canada) Ltd. ("SLR"), an Independent Qualified Person as defined under NI 43-101, to support the disclosure of the updated Douay/Joutel MRE that was previously announced in the Company's news release dated April 27, 2026. The Technical Report is available on SEDAR+ (www.sedarplus.ca) under Maple Gold's issuer profile and on the Company's website at www.maplegoldmines.com.

"Our updated MRE marks a major milestone, demonstrating rapid resource growth at Douay and establishing a maiden high-grade gold resource at Joutel adjacent to existing underground development," stated Kiran Patankar, President and CEO of Maple Gold. "With a total estimated Mineral Resource Inventory of 0.9 Moz at 1.48 g/t Au (19.1 Mt) in the Indicated Resource category and 4.3 Moz at 1.03 g/t Au (130.2 Mt) in the Inferred Resource category, Douay/Joutel combines meaningful scale, an attractive grade profile and significant near-term upside potential. Over the next twelve months, we are planning aggressive, fully funded drill programs and project de-risking initiatives aimed at further expanding the MRE, making new discoveries and building a premier, district-scale gold camp in Québec's established, infrastructure-rich Abitibi Gold Belt."

Table 1: Douay/Joutel Project Updated Mineral Resource Estimate - April 24, 2026

Table 1 Notes:

1. MRE prepared by Mr. Denis Decharte, P.Eng., of SLR Consulting (Canada) Ltd. with an effective date of April 24, 2026.
2. CIM (2014) definitions were followed for Mineral Resources.
3. Mineral Resources are estimated using a long-term gold price of US$2,500 per ounce and a US$:C$ exchange rate of 1:1.35.
4. For Douay:
   a) A minimum mining width of three (3) metres was applied to the resource domain wireframes;
   b) Bulk density was interpolated for the Nika, Porphyry, and 531 zones. For all other zones, bulk density ranging between 2.72 t/m³ and 2.88 t/m³ was assigned to Mineral Resources based on the zone;
   c) The Whittle pit shell used to estimate Mineral Resources is based on a C$4.00/t rock mining cost, a C$3.00/t overburden mining cost, a C$12.50/t processing cost, a C$2.86/t G&A cost, a 90% process recovery, and 25° and 50° pit slopes for overburden and rock, respectively;
   d) Potential open pit Mineral Resources are reported within a Whittle pit shell using an elevated cut-off grade of 0.35 g/t Au. The actual discard cut-off grade is lower at approximately 0.16 g/t Au; and
   e) Underground Mineral Resources are reported within constraining shapes using a cut-off grade of 0.98 g/t Au based on a C$80.00/t underground mining cost, a C$12.50/t processing cost, a C$2.86/t G&A cost, a 90% process recovery and include low grade blocks situated within the constraining shapes.
5. For Joutel:
   a) A minimum mining width of two (2) metres was applied to the resource domain wireframes;
   b) A constant bulk density of 2.85 t/m³ was assigned to all mineralized zones; and
   c) Underground Mineral Resources are reported within constraining shapes using a cut-off grade of 1.70 g/t Au based on a C$120.00/t underground mining cost, a C$25.00/t processing cost, a C$20.55/t G&A cost, a 90% process recovery, and include low grade blocks situated within the constraining shapes.
6. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
7. Numbers may not add due to rounding.
8. Further information about key assumptions, parameters, and methods used to estimate the Mineral Resources, as well as legal, political, environmental, or other risks that may affect the MRE are included in the Technical Report.

The Mineral Resource estimates have been constrained within conceptual open pit and underground shapes that are based on reasonable assumptions for mining, metallurgical, economic, and permitting parameters and demonstrate reasonable prospects for eventual economic extraction (RPEEE). These assumptions include metal prices, recoveries, operating costs, and mine design parameters consistent with comparable projects in the Abitibi Greenstone Belt and reflecting current industry practice at the time of estimation.

For readers to fully understand the information in this news release, they should read the Technical Report in its entirety, including all qualifications, assumptions and risks. The Technical Report is intended to be read as a whole, and sections should not be read or relied upon out of context.

Qualified Person

The Mineral Resources disclosed in this news release have been estimated by Mr. Denis Decharte, P.Eng., an employee of SLR and independent of Maple Gold. By virtue of his education and relevant experience, Mr. Decharte is a Qualified Person for the purpose of NI 43-101. The Mineral Resources have been classified in accordance with CIM Definition Standards for Mineral Resources and Mineral Reserves (May 2014). Mr. Decharte has read and approved the contents of this news release as it pertains to the disclosed MRE. Further information about key assumptions, parameters, and methods used to estimate the Mineral Resources, as well as legal, political, environmental, or other risks that may affect the MRE are included in the Technical Report.

Ian Cunningham-Dunlop, P.Eng. (PEO/EGBC), Executive Vice President of Maple Gold, has reviewed, verified and approved the scientific and technical information related to exploration and Mineral Resource matters contained in this news release. No limitations or failures to verify were identified. Mr. Cunningham-Dunlop is a Qualified Person for the purpose of NI 43-101.

Factors Affecting the Mineral Resources

Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. At the present time, SLR's Qualified Person is not aware of any environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues that may have a material impact on the MRE other than those discussed below and in the Technical Report.

Mineral Resource estimates for the Project may be influenced by technical and economic factors, including assumptions related to metal prices, exchange rates, cut-off grades, geological interpretation, grade continuity, density values, and the design parameters used for open-pit and underground reporting shapes. Actual mineralization may differ from current interpretations due to natural geological variability typical of Abitibi gold deposits and future drilling, sampling, and updated estimation methodologies. Uncertainty increases from the Indicated to the Inferred Resource categories.

About Maple Gold

Maple Gold Mines Ltd. is a well-funded Canadian advanced exploration company focused on advancing its 100%-owned, district-scale Douay/Joutel Gold Project located in Québec's prolific Abitibi Greenstone Gold Belt. Douay/Joutel benefits from exceptional infrastructure access and boasts ~481 square kilometers of highly prospective ground including an established gold mineral resource at the Douay² and Joutel³ deposits, both with significant expansion potential, as well as the past-producing Telbel and Eagle West mines at Joutel. In addition, the Company holds an exclusive option to acquire 100% of the Eagle Mine Property, a key part of the historical Joutel Mining Complex⁴.

Maple Gold's property package also hosts a significant number of regional exploration targets along a 55-kilometer strike length of the Casa Berardi Deformation Zone that have yet to be tested through drilling, making the property ripe for new gold and volcanogenic massive sulphide (VMS) discoveries. The Company is currently focused on carrying out exploration and drill programs to grow mineral resources and make new discoveries to establish an exciting new gold district in the heart of the Abitibi.
