Golden Girl Highlights

• The Golden Girl Property covers 8,471 hectares in the prolific Iskut River region of Northwestern British Columbia, located just 17 km from the Snip Mine and 14 km from the Bronson Airstrip.

• Discovery exploration in 2024 identified a major new gold-silver system measuring 12 km by 7 km with high grade gold-silver mineralization:

  • Grab samples assayed up to 11.28 g/t Au, 3,262 g/t Ag, 5.37% Cu, 20% Pb, and 14.15% Zn.

  • Channel cuts assayed up to 3.74 g/t Au, 2,105.45 g/t Ag, 0.88% Cu, 5.48% Pb, and 7.42% 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 ~1M oz Au, 390k oz Ag, and over 249k kg 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% 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.

• Upcoming Summer 2026 Program Details:

  • Airborne Magnetic survey;
  • Radiometric survey;
  • Mapping, sampling, and channel cutting;
  • LiDAR survey;
  • Photogrametry;
  • Photon assays of samples;
  • Poly-metallic laboratory assays;
  • Staging from Forrest Kerr Camp.

Geologist, Nicolai Goeppel and partner, Ryan Purnell of Higher Ground Exploration Corp. ("Higher Ground"), are leading the 2026 exploration program. Goeppel and 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 (TSXV: GOT) Golddigger discovery and Juggernaut Exploration's (TSXV: JUGR) Big One discovery.

Both Goliath Resources and Juggernaut Exploration are partners within the B-ALL Syndicate ("B-ALL"), the optionor of Golden Girl, holding respectively, 4% and 13% interest in B-ALL, and as such are important strategic partners of the Company. Golden Girl is located approximately mid-way between Goliath's Surebet Discovery and Juggernaut's Big One discovery in the Golden Triangle.

CEO Chris Wensley states, "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."
