K2 Gold Corporation Announces Results of 2026 Reverse Circulation Drilling Program At Si2 Gold Project
K2 Gold Corporation announced the results of its 2026 reverse circulation drilling program at the Company's Si2 Gold Project located in Esmeralda County, Nevada in the Walker Lane trend. Drilling at the widely separated AOI1, AOI3, and AOI4 targets (600 to 1450m apart) 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. The assay results from the 2026 RC drilling campaign at Si2 have confirmed the presence of an extensive gold and silver bearing epithermal system at the Project. This phase of deeper drilling was designed to test for mineralization within the 'boiling zone' modelled by the technical team. The results from this program are encouraging, with the identification of a robust and extensive hydrothermal system now confirmed by drilling over a 1.6 x 1km area and open in all directions. The substantial gold-silver bearing quartz vein cut in hole SR26006 at AOI4 and higher-grade gold in the vein cut at AOI3 in SR26008 were unexpected surprises. Notably, both targets have zero gold expression at surface. The results at all targets make a compelling case for further exploration at Si2. Table 1: Results from the 2026 RC drilling program at Si2, highlights bolded. Note that reported widths are drilled widths and may not represent true thickness at this time. Analytical results for the submitted samples ranged from below detection to 2.367 g/t Au, and below detection to 11.38 g/t Ag. Results from the 2026 program have confirmed K2's exploration thesis, with extensive intervals of disseminated gold +/- silver mineralization within rhyolite and dacite host rocks cut once >150m below the present-day surface. Additionally, multiple blind-to-surface gold-silver-bearing epithermal quartz veins were intersected in the program, representing high-priority follow-up targets. AOI4 - SR26006: Hole SR26006 was drilled to a depth of 537.97m into the AOI4 alteration zone, an east-northeast trending, steeply northwest-dipping expression of strong to intense steam-heated alunite-kaolinite alteration in dacite and rhyolite host rocks extending for >600m along surface. The hole drilled through weakly altered dacite and rhyolite until intersecting the AOI4 structure at a depth of 327.66m down hole, where an interval of rhyolite-hosted gold (and silver) mineralization returning 0.123 g/t Au over 210.31m to EOH was cut. Within this broad interval of gold mineralization, a ~25m drilled thickness of opaque white quartz vein with minor sulphides was cut, returning 18.28m of 0.213 g/t Au including 4.57m at 0.493 g/t Au with 5.01 g/t Ag. The vein is underlain by breccias and quartz-silicified rhyolite in a mixed oxide/sulphide (mostly pyrite) environment containing highly elevated Ba to 5,272 ppm and consistently high Te ranging from 1.95 to 6.36 ppm in addition to strong As but weak Hg. Strong alteration and elevated gold continue beneath the vein interval, increasing in intensity at 394.72 where a 102.1m wide envelope returns 0.161 g/t Au, including 36.57m at 0.226 g/t Au and 1.96 g/t Ag from 429.77m, with sub-intervals of 7.62m at 0.30 g/t Au plus 2.96 g/t Ag from 432.82m, 7.62m at 0.29 g/t Au and 2.74 g/t Ag from 445.01m, and 7.62m at 0.208 g/t Au from 458.72m. The presence of a gold-bearing quartz vein with extensive swaths of gold mineralization with strong As, Ag, Sb, Te and Ba associations suggest, where intersected, may represent a precious-metal dominant feeder structure in the immediate vicinity of potentially stronger mineralization. AOI3 - SR26008: One hole for 475.49m was drilled at the AOI3 target, located 1.3km northeast of the Southern Rhyolite Dome. The target consists of a large zone of steam-heated alteration in dacite and rhyolite with anomalous mercury centred on a structural corridor extending northeast from the Southern Dome. SR26008 drilled through multiple intervals of illite-pyrite-silica altered dacite interlayered with strongly altered rhyolite, both exhibiting highly anomalous Hg from 0 to 150m before cutting a 20m wide fault interval from 176.5m down hole. In the footwall contact of the fault at 196.60m down hole a vuggy quartz vein hosted by rhyolite returned 2.376 g/t Au with 8.13 g/t Ag over 1.52m, with strongly elevated Te, Sb, and Pb and with weakly elevated gold following the vein interval. The hole additionally cut broad intervals of disseminated gold (+/- Ag) hosted by porphyritic dacite and rhyolite with elevated As and Sb, including an interval returning 124.97m of 0.063 g/t Au from 234.7m down hole with individual samples returning 0.431 (and 4.23 g/t Ag), 0.245, and 0.329 g/t Au. A second broad interval intersected at 365.28m down hole returned 57.92m at 0.124 g/t Au, including 4.57m at 0.232 g/t Au and a highlight sample of 0.729 g/t Au & 3.05 g/t Ag. AOI1 & AOI2 - SR26001, SR26002, SR26004, SR26005: The Southern Rhyolite Dome target area (AOI1 and AOI2) represents the southernmost drilled target at Si2 and hosts broad, low-tenor gold mineralization drilled in 2023 beneath an extensive steam-heated alteration cap. The 2026 program aimed to test the target within and below the boiling zone beneath the 2023 drilling. A total of 4 holes were completed (3 completed to target depth, 1 failed) for 1,853m drilled at the target area. Best results were intersected in SR26005 in the core of the target area, where an envelope of gold mineralization returning 73.15m of 0.117 g/t Au was cut beginning at 309.37m down hole. Within this broader envelope of gold mineralization, a core interval was intersected cutting 48.77m of 0.159 g/t Au, including 9.14m of 0.206 g/t Au from 312.42m down hole within a latite dyke with a strong Au-As-Sb-Pb-Te association, and 9.15m of 0.31 g/t Au with 2.96 g/t Ag beginning at 332.23m down hole in an interval of silicified, brecciated rhyolite with a strong Au-Ag-As-Sb-Pb-Mo-Te association. The coincidence of gold mineralization with localized silver, lead, and molybdenum enrichment within the core of the AOI1 target area is considered significant, as it may indicate greater proximity to a deeper hydrothermal source or specific pathway, further demonstrating the robust and extensive reach of the hydrothermal system at Si2. Holes SR26001 & SR26002 returned multiple intervals of weakly anomalous gold and may have been drilled slightly outboard of the primary fluid conduit at AOI1.
