GOLD RUNNER EXPLORATION ANNOUNCES COMMENCEMENT OF RADIOMETRIC AND AIRBORNE MAGNETIC SURVEYS AT GOLDEN GIRL PROPERTY, GOLDEN TRIANGLE B.C.

Further to Gold Runner Exploration Inc.'s press release dated May 26, 2026, the radiometric and airborne magnetic surveys designed for its Golden Girl project in the Golden Triangle of British Columbia, being performed by Precision GeoSurveys Inc., have commenced. Data acquisition has been completed, and processing and interpretation of the data is under way and is expected to be ready and available for further guidance by Gold Runner's field teams by the time they mobilize. Mobilization is on schedule for July 12, 2026, with fieldwork beginning on July 13, 2026.

Golden Girl highlights:

• The Golden Girl property covers 8,471 hectares in the prolific Iskut River region of northwestern British Columbia, located just 17 kilometres from the Snip mine and 14 kilometres from the Bronson airstrip.
• Discovery exploration in 2024 identified a major new gold-silver system measuring 12 kilometres by seven kilometres with high-grade gold-silver mineralization:
  • Grab samples assayed up to 11.28 grams per tonne gold, 3,262 grams per tonne silver, 5.37 per cent copper, 20 per cent lead and 14.15 per cent zinc.
  • Channel cuts assayed up to 3.74 g/t Au, 2,105.45 g/t Ag, 0.88 per cent Cu, 5.48 per cent Pb and 7.42 per cent Zn.
• High-grade mineralization occurs in structurally controlled shear zones with sulphide-rich veins, stockwork and breccias, similar to the nearby past-producing Snip gold mine (which historically produced approximately one million ounces Au, 390,000 ounces Ag and over 249,000 kilograms Cu). (The reader is reminded that the information provided herein from neighbouring projects and properties is not necessarily indicative of resources and should not be relied upon for the determination of mineralization or potential results of the company's properties.)
• More than 95 per cent of the property has never undergone systematic modern exploration. Recent rapid glacial retreat and melting snowpacks have exposed vast areas of previously buried bedrock, opening large, untouched tracts of ground for immediate mapping and sampling.
• Coming summer 2026 program details include:
  • Airborne magnetic survey;
  • Radiometric survey;
  • Mapping, sampling and channel cutting;
  • Lidar survey;
  • Photogrametry;
  • Photon assays of samples;
  • Polymetallic laboratory assays;
  • Staging from Forrest Kerr camp.

Geologist Nicolai Goeppel and partner Ryan Purnell of Higher Ground Exploration Corp. are leading the 2026 exploration program. Mr. Goeppel and Mr. Purnell bring long-term experience working in the world-renowned Golden Triangle region of northwestern British Columbia and contributed to relevant exploration discoveries, including Goliath Resources' Golddigger discovery and Juggernaut Exploration's Big One discovery.

Both Goliath Resources and Juggernaut Exploration are partners within the B-ALL Syndicate, the optionor of Golden Girl, holding respectively, 4-per-cent and 13-per-cent interests in B-ALL, and as such are important strategic partners of the company. Golden Girl is located approximately midway between Goliath's Surebet discovery and Juggernaut's Big One discovery in the Golden Triangle.

Chief executive officer Chris Wensley stated: "The diligence, expertise and reliable effectiveness of this highly experienced and knowledgeable exploration team continue to show at every stage of the rapidly evolving and developing Golden Girl project. This is an exciting time for the Gold Runner and our shareholders as we launch our initial summer 2026 program, which, based on the initial discovery exploration sampling, we are very optimistic will bring about strong results."
