TORONTO, ON / ACCESS Newswire / July 13, 2026 / Galway Metals Inc. (TSXV:GWM)(OTCQB:GAYMF) (the "Company" or "Galway") announced today an updated Mineral Resource Estimate ("MRE") for its 100%-owned Clarence Stream Gold Project in southwest New Brunswick. The updated MRE reports Indicated Mineral Resources of 27.2 million tonnes grading 1.62 g/t Au containing 1.42 million ounces of gold and Inferred Mineral Resources of 28.5 million tonnes grading 1.40 g/t Au containing 1.29 million ounces of gold. The updated estimate also includes approximately 19,500 tonnes of contained antimony in the Indicated category and 3,100 tonnes in the Inferred category, representing increases of approximately 103% and 45%, respectively, compared to the 2022 Mineral Resource Estimate¹.

"This updated Mineral Resource Estimate marks a significant milestone for the Clarence Stream Project," stated Robert Hinchcliffe, President and CEO of Galway Metals. "The 20% increase in total contained gold, together with the 54% increase in Indicated gold ounces, provides a substantially stronger foundation for the Project. We are extremely happy with our new resource estimate and look forward to an exciting 2026.

"Approximately half of our contained Indicated gold ounces occur at grades above 3.0 g/t Au (see Table 2.0 below), underscoring the quality of the updated resource and its potential to support future development. Most importantly, the North, South and Southwest Deposits remain open for expansion through ongoing drilling, while our broader 65-kilometre Clarence Stream district continues to provide significant discovery potential."

"With four drill rigs currently operating as part of our planned 40,000-metre 2026 drill program, Galway is well positioned to continue expanding and upgrading the Mineral Resource, make new discoveries across our 65-kilometre district, and advance Clarence Stream through future economic studies.

Notably, the next milestone for Clarence Stream is the Preliminary Economic Assessment (PEA). We are currently reviewing proposals for this next step."

Notes: 1. CIM (2014) definitions were followed for Mineral Resources. 2. Mineral Resources are estimated at a cut-off grade of $31/t NSR and $171/t NSR for open pit and underground, respectively. 3. Mineral Resources are estimated using a long-term gold price of US$3,250 per ounce, a long-term antimony price of US$29,000/t, and a US$/C$ exchange rate of 1.35. 4. Minimum mining widths of approximately three metres were used for the open pit portion of the North and South Zone deposits. A minimum mining width of approximately 1.5 m was used for the underground portion of the South Zone deposit. A minimum width of approximately two metres was used for the Southwest deposit. 5. Bulk density is 2.74 t/m³ for the North Zone mineralization, is 2.81 t/m³ for the South Zone mineralization, and 2.73 t/m³ for the Southwest Deposit mineralization. The bulk densities for the Southwest Zone mineralization range from 2.39 t/m³ to 2.77 t/m³. 6. Mineral Resources are inclusive of Mineral Reserves. 7. There are no Mineral Reserves at Clarence Stream. 8. Open pit Mineral Resource statements are prepared using surfaces generated using the pseudoflow algorithm. 9. Underground Mineral Resource statements are prepared using three-dimensional shapes to outline volumes of continuous blocks which satisfy the cut-off grade and minimum width criteria. 10. Numbers may not add due to rounding. 11. Antimony contents are rounded to the nearest 100 tonnes.
