June 18, 2025 - Vancouver, Canada - Klondike Silver Corp. (the "Company") plans to continue an underground drill program during 2025 at the Silvana Mine, targeting western extensions of the mine within the historic Silvana claim block that the Company owns in southeastern British Columbia.

Exploration has advanced according to plan along the interval of approximately 1220 metres (4000 feet) of unexplored lode structures between the Silvana Mine and the Mammoth Mine to the west. Drill stations have been sited at approximately 80 metres (250 foot) intervals along the 4625 West Level.

Five holes were drilled in a fan southerly from drill station #2.  Four of the holes intersected the Main Vein structures that were projected downwards from the surface workings of the historic Jennie Lind-Read and Evening Lode mines and one hole was ended short of the zone in a fault with a strong flow of water.

Three uncompleted holes were drilled northerly from drill station #2. These holes will be extended in the 2025 program to cross the projected locations of hanging wall and footwall lodes of the Carnation structure.

Core logging and core sampling of drilling to date has been completed. Intervals of core were marked for sampling. These cores were sawed lengthwise with one half bagged and sent to an independent lab for analysis, and one half was retained for further inspection. Analytical results were received from Activation Labs. No anomalous values of silver, lead and zinc were reported.

Klondike president and CEO, Mr. Tom Kennedy stated: “We are extremely pleased to have intersected an extension of the Main Vein structure that supported production at the Silvana Mine and numerous other historic mines on the company's tenure in the Slocan Mining Camp. The Silvana Silver Mile is 100% within Klondike's claim block. Klondike's management and exploration team are encouraged by the potential to find and develop a new zone of mineralization in the Main Vein structure between the Mammoth and Silvana mines in the Company's 1.5 km Silvana Silver Mile zone, as combined historic production of the Main Lode included 28 million oz silver, 209 million lbs zinc and 258 million lbs lead.”
