STLLR Gold Inc. announced the remaining infill drilling results using artificial intelligence technology ("AI") at the Company's Tower Gold Project ("Tower") in the Timmins Mining Camp in Ontario, Canada. Zone, Hole ID, Assay Result, 903, MGA25-237, 2.61 g/t Au over 13.65 m (10.39 m TT), including 3.42 g/t Au over 2.80 m (2.13 m TT), including 5.30 g/t Au over 3.90 m (2.97 m TT), 903, MGA 25-240, 1.42 g/t Au across 11.15 m (7.27 m TT), Including 2.77 g/t Au over 2.,30 m (1.50 m TT) and, 1.33 g/t Au over 17.00 m (11.10 m TT), Including 1.85 g/t Au over 9.50 m (6.20 m TT), 903,MGA25-239, 1.67 g/t Au over 10.85 m (7.75 m TT), Including 2.36 g/t Au over 4.50 m (3.21 m TT), 55, MGA25-542, 2.18 g/t Au over 8.00 m (7.22 m TT), including 4.33 g/t Au across 3.40 m (3.07 m TT) Grams per tonne gold ("g/t Au"); Metres ("m"); True thickness ("TT") Keyvan Salehi, P.Eng., MBA, President, CEO, and Director of STLLR, commented: "Our infill drilling program continues to validate the enhanced block model introduced in the Tower 2025 MRE1. The latest results reaffirm near-surface mineralization with strong potential for resource conversion to higher- confidence categories.

Notably, several holes intersected grades above the average open pit grade defined in the 2025 MRE, underscoring the upside potential within existing pit shells. In parallel, the company have completed a series of technical drill holes to support advancing Pre-Feasibility Study work programs. This includes eight geotechnical holes across the broader Tower deposit areas to inform slope design, overburden characterization, and overall geotechnical modelling, as well as three metallurgical holes in the Golden Highway area to support ongoing process optimization and recovery modelling. These efforts are foundational to de-risking the Project and refining conceptual mine plan.

In addition to today's positive results from the 903 and 55 Zone deposits, the company also look forward to reporting on assay results from the Hollinger Tailings Project characterization program in the near future." 903 Zone and 55 Zone Infill Drilling. The 903 Deposit, part of the Garrison Area at Tower, features gold mineralization linked to quartz veining within syenites hosted in highly deformed, carbonatized ultramafic volcanics of the Kidd-Munro assemblage. Using AI to optimize drill meterage and mineral resource conversion, STLLR's infill program intersected near-surface mineralization with grades higher than the current 903 and 55 Zone Deposits 2025 MRE open-pit mineralization1, potentially enhancing confidence in the targeted areas.
