STLLR Gold intercepts 3.11 g/t Au over 15.70 m at Jonpol, Tower

Toronto, Ontario--(Newsfile Corp. - August 4, 2026) - STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) ("STLLR" or the "Company") reports additional assay results from its 2026 drilling program at the Jonpol Deposit (" Jonpol ") at the Garrison Property of the Tower Gold Project (" Tower " or the " Project ") in the Timmins Mining Camp in Ontario, Canada.

" g/t Au " = grams per tonne gold; " m " = metres; " TT " = True Thickness

"Our latest drilling continues to deliver high-grade, near-surface gold intersections, demonstrating the exceptional potential of the Jonpol Deposit," said Keyvan Salehi, P.Eng., MBA, President, CEO, and Director of STLLR Gold. "The combination of mineralized intervals, strong grades, and high metal factors in several holes demonstrates the continuity and strength of the system. These results provide further confidence in the potential to grow and upgrade the Jonpol mineralization, which we believe can make a meaningful contribution to improving the overall economics and production profile of the Tower Gold Project."

"With the success we've seen at Jonpol, we plan to continue targeting higher-grade, near-surface mineralization in the Garrison Property of Tower for the remainder of 2026."

The Jonpol Deposit is situated in the Garrison Property at the eastern end of Tower (see Figure 1) along the Munro Fault, a splay from the regional Destor-Porcupine Fault Zone (" DPFZ "). Mineralization is hosted in structurally controlled alteration zones within mafic to ultramafic rocks and gold mineralization is closely associated with felsic intrusive rocks.

STLLR has completed 8,536 m of drilling at Jonpol for its first-half 2026 drill program, with assay res
