K2 Gold drills disseminated mineralization at Si2 Project

Vancouver, British Columbia--(Newsfile Corp. - June 18, 2026) - K2 Gold Corporation (TSXV: KTO) (OTCQX: KTGDF) (FSE: 23K) ("K2" or the "Company") today announced the results of its 2026 reverse circulation ("RC") drilling program at the Company's Si2 Gold Project located in Esmeralda County, Nevada in the prolific Walker Lane trend. Highlights Drilling at the widely separated AOI1, AOI3, and AOI4 targets (600 to 1450m apart) successfully confirms the presence of a very large, fertile epithermal gold system capable of producing broad intervals of disseminated gold as well as large epithermal quartz veins with the capacity to carry higher grades at depth. Hole SR26006 at AOI4 returns consistently elevated gold over 210m Gold mineralization is consistently intersected beneath an extensive blanket of advanced argillic alteration, consistent with the model of a preserved steam-heated epithermal system and analogous with the >15Moz Silicon/Arthur Gold Project, which was initially identified by the same team that staked Si2.

John Robins Executive chairman of K2 stated: "While this round of drilling did not intersect economic grades it nonetheless demonstrates the presence of a very large gold bearing system at depth. The fluid inclusion results ( see K2 News Release dated January 19, 2026 ) correlate positively with the drill results observed to date and the extensive(8km 2 ) surface alteration expression is consistent with the steam heated alteration zone associated with fully preserved epithermal systems." " The assay results from our 2026 RC drilling campaign at Si2 have clearly confirmed the presence of an extensive gold and silver bearing epithermal system at the Project." Stated Anthony Margarit, President and CEO of K2 Gold. " This phase of deeper drilling was designed to test for mineralization within the 'boiling zone' modelled by our technical team.
