Gold Runner Exploration samples 25,306 g/t Ag, 11.22 g/t Au at Golden Girl

Vancouver, British Columbia--(Newsfile Corp. - August 31, 2026) - Gold Runner Exploration Inc. (CSE: GRUN) (FSE: CE70) (" Gold Runner " or the " Company ") is pleased to announce initial results for samples assayed up to 25,306 g/t Ag (grams per ton Silver) with 11.2 g/t Au (grams per ton Gold), or 12.7 ounces per ton Gold Equivalent, from the newly discovered 350 meter long and up to 50 meter wide Gold Stack Trend which remains open on the Golden Girl property, Golden Triangle, B.C. Eleven samples from the first batch of 60 samples collected during the Golden Girl 2026 exploration program assayed over 1 g/t AuEq, seven of which assayed over 10 g/t AuEq. This year's exploration program is designed to generate drill targets for the planned 2027 inaugural drill program. Strong initial results combined with confirmation and discovery of multiple showings that have scale as well as high-grade precious and base metals mineralization, bode well for a successful maiden drill program in 2027.

2026 exploration highlights:

Initial assay results from surface sampling at the newly discovered Gold Stack Trend returned grades up to 396.66 g/t or 12.7 oz/t AuEq (sample N908103 carried 11.22 g/t Au, 25,306 g/t Ag, 2.96% Cu, 8.19% Pb, and 5.89% Zn). Eleven samples assayed over 1 g/t AuEq and 7 samples assayed over 10 g/t AuEq. (See table below)

The Gold Stack Trend forms a broad mineralized corridor up to 50 meters wide with a confirmed exposed strike length of 350 meters that remains open for expansion.

Mineralization on the Gold Stack Trend is characterised by significant concentrations of galena, sphalerite, and tetrahedrite with lesser chalcopyrite and pyrite found predominantly in veins and veinlets within the altered shear zone.
