Au Gold Corp Samples 40 g/t and 22 g/t Gold from the Harvey’s Reef Complex Defining Additional High-Priority Drill Targets and Engages Prestige Drilling at the Havelock Gold-Antimony Project

5 November, 2026 – Au Gold Corp (TSXV: AUGC) (the “Company” or “AUGC”) is pleased to provide a target development update for the Havelock Gold-Antimony project in Victoria, Australia.

Marc Blythe, founder & CEO of Au Gold, commented, “The Harvey’s Reef Complex target delivered high-grade gold-bearing surface samples from shallow intermittent workings along 600 m of the main reef trend in addition to a historic shallow 9.24 g/t gold over 1.5 m RC drill intercept on a parallel reef to the west.  The Harvey’s Reef Complex adds to AUGC’s growing list of targets and we are eager to advance this target area with the first diamond drill testing.”

Harvey’s Reef is located 800 metres (“m”) west of the Shaw-McFarlane Trend (SMT) and was explored by prior operators in the 1980’s and 1990’s targeting low-grade open pit style mineralization.  Prior exploration includes RC and RAB drilling.  Previous descriptions and sampling results at Harvey’s Reef were released April 8, 2026.
