Klondike Gold Completes Phase 1

Exploration Program

Vancouver, British Columbia, Canada – Klondike Gold Corp. (TSX.V: KG; FRA: LBDP; OTCQB:

KDKGF) (“Klondike Gold” or the “Company”) is pleased to announce the compleƟon of Phase 1

drilling of the mul Ɵphase 2025 Explora Ɵon program. A total of 13 diamond drill holes were

completed on the Company’s 100% owned Klondike District Property (the “Property”) in the

Dawson mining district, Yukon Canada. (see Figure 1).

Summary

 CompleƟon of 2,354.70m 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

 ProspecƟng, mapping, and relogging are ongoing to refine 3-D geological, structural, and

mineralizaƟon models within the Eldorado Target.

 Montana Creek placer mining advancing steadily

Peter Tallman, President and CEO of Klondike states: “Years of explora Ɵon are now coming

together as we step out from known high grade gold structures in the most expedi Ɵous way

possible targeƟng lateral and verƟcal extensions to idenƟfied resource areas1 along the Eldorado

Target. We’re intently focused on demonstraƟng the outsized potenƟal 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 exis Ɵng large placer ‘pay streak’

are all proceeding well which raises expectaƟons for a great season of gold recovery.”

Phase 1 Drill Program

Klondike Gold’s Phase 1 program targeted lateral and verƟcal extensions of high-grade gold vein

zones and aimed at tesƟng the orientaƟon of major structures that control gold deposiƟon along

porƟons of the Eldorado Target (see Figure 2). Understanding these major controls will guide the

next phase of drilling which is planned to include deep holes up to 750m of length. Phase 1 Drilling

began on April 28 th and was executed by Kluane Drilling, based out of Whitehorse YT. A total of

2,354.70 meters of drilling was completed across 13 holes which varied from 50–350 meter

lengths (see Figure 3). Samples were collected along prospecƟve intersecƟons throughout the 13

drill holes have been shipped to MSA Labs in Prince George, BC and results are pending.

As referenced by the April 24 th, 2025Klondike Gold News release, the Eldorado Target focusses

current exploraƟon on a 5km strike and 1400m width area which covers a major crustal structure

mapped by Klondike Gold (see Figure 2). Prior to the 2025 ExploraƟon season, drilling successfully

and prudently focused on exploring orogenic gold deposi Ɵon to shallow depths of ~75 meters

below surface. With this data now in place to guide deeper exploraƟon, prospecƟve efforts target

lateral and depth extensions of previously defined mineralized zones with planned drillholes

ranging from 100 meters up to 750 meters in length. To be Ʃer target mineralizaƟon to greater

depths, priority work includes mapping, prospecƟng, and detailed relogging to refine constructed

3-D lithology, structural, and mineralizaƟon models.

Montana Creek Placer Property Lease Update

Work is well underway on the Montana Creek Placer Property Lease (refer to the Company’s

March 11, 2025 News Release) under the agreed ‘ Mining Lease and Op Ɵon t o Purchase

Agreement with Armstrong Mining Corp. (see Figure 1 for locaƟon). A substanƟal overburden drill

program tesƟng the Montana Creek surface gravel alluvial gold to expand the placer “pay streak”

will complete shortly. Overburden stripping is ongoing (see Figure 4) and ‘pay gravel’ is being

stockpiled in advance of work underway commissioning the sluice (gold recovery) plant.
