Vancouver, BC — November 6, 2025 — Leads & Copy — Klondike Gold Corp. announced assay results from its 2025 Phase 1 diamond drill program, which totaled 2,354.70 meters across 13 holes. The program tested the orientation of major structural features believed to control gold deposition at the company’s 100%-owned Klondike District Property in the Dawson mining district, Yukon, Canada.

Highlighted results from the drill program include:

• Hole EC25-554: 0.25 g/t Au over 64.80 meters from 7.55 to 72.35 meters, including 1.30 g/t Au over 10.00 meters from 62.35 to 72.35 meters.
• Hole EC25-557: 0.13 g/t Au over 14.50 meters from 171.50 to 186.00 meters.
• Hole EC25-557: 0.14 g/t Au over 10.50 meters from 197.00 to 207.50 meters.
• Hole EC25-561: 0.76 g/t Au over 2.00 meters from 121.50 to 123.50 meters.
• Hole EC25-562: 0.47 g/t Au over 5.00 meters from 26.00 to 31.00 meters.
• Hole EC25-566: 5.20 g/t Au over 3.00 meters from 75.00 to 78.00 meters.

According to Klondike Gold Corp. CEO and President Peter Tallman, the Phase 1 drill holes were designed to test the orientation of structural controls on specific faults and estimate offset distances rather than directly target mineralization. He added that the fact that several holes encountered gold mineralization, including a new gold discovery zone in EC25-566, suggests the company is on the right path to understanding the geological architecture that originally emplaced the substantial gold endowments within the historic Klondike Gold District.

The Phase 1 drill holes were completed outside of previously defined Lone Star and Stander mineral resource areas. Hole EC25-566 intersected 5.20 g/t Au over 3m, representing a new gold mineralization discovery.

The intent of Phase 1 drilling was to constrain or discern the relative ages of these structures and provide information on potential displacement, laying the groundwork for future mineralization-focused drilling later in Phase 3 drilling. Six holes intersected notable gold mineralization, highlighting the potential relationship between key structural controls and gold-bearing zones.

Following the success of Phase 1, the company initiated Phase 2 exploration, focusing on completing a detailed 3D structural and lithologic model for the main resource areas. This work included:

• Re-logging over 60,000 meters of historical drill core.
• Conducting detailed analysis of local fault systems.
• Collecting Short Wave Infrared (SWIR) measurements on Phase 1 drill core from the 2025 season.
• Evaluating correlations between lithology and gold mineralization.

The evolving exploration model suggests multiple ages and orientations of faulting, which has positive implications for guiding the expansion of the company’s existing resources at the Lone Star and Stander deposits and for new exploration discoveries throughout the property.

Peter Tallman, President and CEO of Klondike Gold Corp., reviewed and approved the technical and scientific information in the news release.

Klondike Gold Corp. is a Vancouver-based gold exploration company advancing its 100%-owned Klondike District Gold Project in Dawson City, Yukon. The project targets gold associated with district-scale orogenic faults along the 55-kilometer length of the Klondike Goldfields placer district. Gold mineralization and indicated/inferred mineral resources have been identified at the Lone Star Zone and Stander Zone.

The company retains a 10% production royalty on the active Montana Creek placer property with payments capped at $9.5 million total over six years. The company is focused on exploration and development of its 729 square kilometer property, accessible by scheduled airline and government-maintained roads located on the outskirts of Dawson City, Yukon, within the Tr’ondëk Hwëch’in First Nation traditional territory.
