Kalo Gold Defines Kilometre-Scale Epithermal Gold Targets and Structural Corridors at Wainikoro Within a 40 km Gold Corridor, Vatu Aurum, FijiVANCOUVER, BC / ACCESS Newswire / April 22, 2026 / Kalo Gold Corp. (TSXV:KALO)(OTCID:KLGDF)(FSE:9M51) ("Kalo" or the "Company") reports results from ongoing exploration at Wainikoro, located approximately 5 km west of Aurum Prime within its 100%-owned Vatu Aurum Project, Fiji. Drill hole VA26-DH19 intersected interpreted bladed carbonate textures - observations consistent with the upper levels of a boiling-stage, low-sulphidation epithermal system - within kilometre-scale arsenic-in-soil anomalies along the Nubu Graben.Two exploration diamond drill holes (VA26-DH18 and VA26-DH19), together with trenching and systematic soil geochemistry, have defined kilometre-scale structural corridors at Wainikoro along the Nubu Graben and associated splay structures. Certified Fire Assay results for both holes are pending. Integrated with an airborne magnetic and radiometric survey now mobilized, these observations are advancing Wainikoro toward drill-ready targets for follow-up drilling. Wainikoro is emerging as a key component of the Company's broader exploration strategy across the Vatu Aurum Project, where multiple structurally controlled targets are being advanced systematically along a 40 km gold corridor.KEY HIGHLIGHTSKilometre-scale arsenic-in-soil anomalies: >1 km anomaly at Kope Road North (KRN), >750 m at Kope Road South (KRS), 1 km at Narusa Creek (NRC) and 300 m at Wainikoro West (WKW) (above 20 ppm As contour), spatially associated with Nubu Graben structuresInterpreted boiling indicators observed in drilling: VA26-DH19 (270.6 m) intersected bladed carbonate textures replaced by quartz and sulphide pseudomorphs, consistent with a boiling-stage epithermal environmentGold confirmed at surface: trenching returned up to 2 m at 3.41 g/t Au (TR13-5K04) and 32 m at 0.56 g/t Au (TR17-5K05); detectORE™ soil results up to 1,640 dU (~1.64 g/t Au) at KRN and up to 1,322 dU (~1.32 g/t Au) at KRSTwo drill holes completed: VA26-DH18 (245.7 m) at KRS and VA26-DH19 (270.6 m) at KRN; certified Fire Assay results pendingNubu Graben: Wainikoro lies along a 40 km NE-trending gold-in-drainage BLEG and stream sediment geochemical anomaly corridorCapital-efficient path to drill-ready targets: systematic mapping, geochemistry, and trenching are defining the highest-confidence structural corridors prior to follow-up drilling, supported by the upcoming high-resolution airborne magnetic surveyWainikoro: Two Exploration Drill Holes Complete; Kilometre-Scale Epithermal Targets DefinedExploration at Wainikoro has delineated multiple arsenic-in-soil anomalies associated with historical magnetic low features, interpreted to represent zones of hydrothermal alteration and fluid flow along the Nubu Graben and associated splay structures. These features are characteristic of low-sulphidation epithermal systems, where hydrothermal fluids alter host rocks and create pathways for mineralization. Two exploration drill holes were completed to advance the geological model, improve understanding of system scale, and provide context for the airborne geophysical survey. A total of 11,251 soil samples have been collected to date at Wainikoro with more than 7,500 additional samples planned with grids illustrated in Figures 3 and 4.Refining Targets Through Integrated ExplorationWainikoro has been advanced with systematic soil geochemistry, trenching, and first-pass drilling - consistent with the Company's strategy of defining drill-ready targets through systematic surface exploration.Wainikoro is a laterally extensive, structurally controlled low-sulphidation epithermal system - a target geometry that is defined globally through wide-spaced, surface-led exploration (mapping, geochemistry, trenching, geophysics), with drilling deployed to test corridors at depth. The Qiriyaga Complex is a vertically zoned, diatreme-hosted target where drilling is designed to test architectural depth toward an interpreted feeder zone at approximately 395 metres. The two programs are stage-appropriate to different target geometries.The Company is applying a disciplined, data-led approach at Wainikoro and across the entire Vatu Aurum Project. Ongoing work integrates geological, geochemical, geophysical, and structural datasets - including LiDAR-derived lineation mapping, which has highlighted zones of dilation and fluid focusing on fault intersections and flexures - to refine targeting before advancing to more capital-intensive drilling. Upcoming surface work will include systematic stream sediment and soil sampling, trenching, and geological mapping to define drill-ready targets. In parallel, the high-resolution airborne magnetic survey will commence shortly, with the survey helicopter now in camp. No further drilling will be completed on the Project until the magnetic survey is complete, and the resulting data have been integrated int
