KLONDIKE GOLD COMPLETES PHASE 1 EXPLORATION PROGRAM

Klondike Gold Corp. has completed phase 1 drilling of the multiphase 2025 exploration program. A total of 13 diamond drill holes were completed on the company's 100-per-cent-owned Klondike district property in the Dawson mining district, Yukon, Canada.

Summary

• Completion of 2,354.70 metres across 13 diamond drill holes throughout phase 1;
• Assay results from 13 holes are currently pending;
• Planning of holes up to 750 meter in length for the upcoming drill phase.;
• Prospecting, mapping and relogging are continuing to refine 3-D geological, structural and mineralization models within the Eldorado target;
• Montana Creek placer mining advancing steadily.

Peter Tallman, president and chief executive officer of Klondike, states: "Years of exploration are now coming together as we step out from known high-grade gold structures in the most expeditious way possible targeting lateral and vertical extensions to identified resource areas1 along the Eldorado target. We're intently focused on demonstrating the outsized potential of bedrock sourced gold deposits within the historic Klondike gold district and are making steady progress. We are also pleased to see our colleagues at Armstrong Mining making solid progress at our Montana Creek placer mine. Stripping, mining and drilling ahead to expand the existing large placer 'pay streak' are all proceeding well which raises expectations for a great season of gold recovery."

Phase 1 drill program

Klondike Gold's phase 1 program targeted lateral and vertical extensions of high-grade gold vein zones and aimed at testing the orientation of major structures that control gold deposition along portions of the Eldorado target. Understanding these major controls will guide the next phase of drilling which is planned to include deep holes up to 750 m of length. Phase 1 drilling began on April 28 and was executed by Kluane Drilling, based out of Whitehorse, Yukon. A total of 2,354.70 metres of drilling was completed across 13 holes which varied from 50- to 350-metre lengths. Samples were collected along prospective intersections throughout the 13 drill holes have been shipped to MSA Labs in Prince George, B.C., and results are pending.

As referenced by the April 24, 2025, Klondike Gold news release, the Eldorado target focuses current exploration on a five-kilometre strike and 1,400 m width area which covers a major crustal structure mapped by Klondike Gold. Prior to the 2025 exploration season, drilling successfully and prudently focused on exploring orogenic gold deposition to shallow depths of approximately 75 metres below surface. With this data now in place to guide deeper exploration, prospective efforts target lateral and depth extensions of previously defined mineralized zones with planned drill holes ranging from 100 metres up to 750 metres in length. To better target mineralization to greater depths, priority work includes mapping, prospecting and detailed relogging to refine constructed 3-D lithology, structural and mineralization models.

Montana Creek placer property lease update

Work is well under way on the Montana Creek placer property Lease (refer to the company's March 11, 2025, news release) under the agreed mining lease and option to purchase agreement with Armstrong Mining Corp. A substantial overburden drill program testing the Montana Creek surface gravel alluvial gold to expand the placer "pay streak" will complete shortly. Overburden stripping is continuing and pay gravel is being stockpiled in advance of work under way commissioning the sluice (gold recovery) plant.

About Klondike Gold Corp.

Klondike Gold is a Vancouver-based gold exploration company advancing its 100-per-cent-owned Klondike district gold project located at Dawson City, Yukon, one of the top mining jurisdictions in the world. The Klondike district gold project targets gold associated with district scale orogenic faults along the 55-kilometre length of the famous Klondike goldfields placer district. Multikilometre gold mineralization has been identified at both the Lone Star zone and Stander zone, among other targets. The company has identified a pit-constrained mineral resource estimate of 469,000 indicated and 112,000 inferred gold ounces, a milestone first for the Klondike district. The company retains a 10-per-cent 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 727-square-kilometre property accessible by scheduled airline and government-maintained roads located on the outskirts of Dawson City, Yukon, within the Tr'ondek Hwech'in First Nation traditional territory.
