Kalo Gold Corp Identifies In-Situ Epithermal Gold Veins At Wainikoro With Surface Values Up To 3,397 Du Estimated 3.40 G/T Au
Kalo Gold Corp. has reported that its 2026 surface campaign at Wainikoro, on the 100%-owned Vatu Aurum Project in Fiji, has identified multiple in-situ low-sulphidation epithermal quartz veins in rock — including a chalcedonic quartz vein returning 1,157 dU (~1.16 g/t Au estimated) and surrounding float at 3,397 dU (~3.40 g/t Au estimated) as determined through detectORE analysis. Integrated 2026 soil-geochemistry and airborne magnetic data extend the previously disclosed greater than 1 km arsenic-in-soil anomaly at Wainikoro to approximately 1,800 m of strike length, oriented NW–SE within the central magnetic-low feature. The recently completed 6,212 line-kilometre airborne magnetic and radiometric survey is being integrated with surface mapping, trenching and soil geochemistry, with an induced polarization survey at Wainikoro planned for July 2026 mobilisation; drilling will follow once the integrated dataset is in hand. The 2026 surface campaign at Wainikoro identified multiple in-situ low-sulphidation epithermal quartz veins in rock, including a chalcedonic quartz vein at 1,157 dU (~1.16 g/t Au estimated) with surrounding float up to 3,397 dU (~3.40 g/t Au estimated). Additional headline surface values include 2,728 dU (~2.73 g/t Au estimated) from a chalcedonic-banded quartz vein in bedded tuff; 1,364 dU (~1.36 g/t Au estimated) from the adjacent silicified polymictic breccia; 916 dU and 904 dU from silicified host rocks. Trench channel sampling returned values up to 1,446 dU (~1.45 g/t Au estimated); a 13-metre channel interval at TR26-011 averaged 275 dU (~0.28 g/t Au estimated) within silicified fault-controlled structures. Arsenic-in-soil, magnetic-low features and surface vein samples converge on an approximately 1,800 m NW–SE corridor within the central magnetic-low feature. Beyond the central approximately 1,800 m corridor, additional arsenic-in-soil anomalies across the Wainikoro area coincide with discrete magnetic-low features in the recently completed 6,212 line-kilometre airborne magnetic survey, extending the magnetic-low-controlled target footprint across Wainikoro. Certified Fire Assay results from VA26-DH18 and VA26-DH19 are pending. The 2026 soil-geochemistry programme has collected 9,994 soil samples to date with a further 5,390 samples planned across magnetic-driven grids based on the recently completed airborne magnetic survey. This work builds directly on the updated structural and geological interpretation announced on 27 May 2026, which framed the Vatu Aurum Project as a single, multi-phase, structurally reactivated volcanic complex rather than a series of separate prospects. Earlier drilling was conducted concurrently with surface mapping, geochemistry and the airborne magnetic survey — providing the geological control required to interpret the geophysical response and to integrate subsurface observations into the project-wide model. The Company identifies the West-East Transfer Zone as a regional accommodation corridor expressed as a continuous magnetic low and interpreted as a first-order control on fluid migration across the project. The Nubu Graben is cut by a network of NW–SE oblique faults, Riedel shears and transfer faults that, on present interpretation, perform the dominant gold-hosting structural work at Wainikoro and property wide. The highest fracture density and dilation are expected at intersections of the oblique fault network with the West-East Transfer Zone and the graben margins. Surface geological mapping, soil and rock geochemistry, detectORE screening and trench results at Wainikoro converge with the new airborne magnetic data on the same structural intersections — providing a coherent geological explanation for the distribution of gold, arsenic, silicification and hydrothermal brecciation observed at surface, and sharpening the Company’s ability to vector toward priority drill targets. The 2026 field campaign at Wainikoro extends the surface programme reported in the Company’s 22 April 2026 news release, which disclosed peak detectORE soil values of 1,640 dU (~1.64 g/t Au estimated) and 1,322 dU (~1.32 g/t Au estimated) within the previously defined arsenic-in-soil corridor. The traverse and rock-sampling campaign has identified multiple in-situ low-sulphidation epithermal quartz veins, silicified breccias and altered host rocks returning detectORE values of up to 3,397 dU (~3.40 g/t Au estimated). An important geological observation is newly identified in-situ chalcedonic quartz veins with results of 1,157 dU, ~1.16 g/t Au estimated. It occurs immediately adjacent to the KRN-ZB26-021 silicified polymictic breccia (1,364 dU, ~1.36 g/t Au estimated) and is surrounded by float material returning values up to 3,397 dU (~3.40 g/t Au estimated) at KRN-LR26-027A, consistent with weathering of a gold-bearing vein and breccia source at or near the float location. Table 1 summarises the detectORE values and lists multiple epithermal quartz veins identified across the campaign area, distinguishable by host rock, orientation and texture. These samples sit along an approximately 1,800 m NW–SE strike length within the central magnetic-low feature at Wainikoro. DetectORE values from 2026 field traverse and rock-sampling campaign at Wainikoro are summarised in Table 1. Rock-type descriptions are diagnostic of the upper levels of a low-sulphidation epithermal gold system — chalcedonic and comb-textured quartz veining, silicified polymictic breccias, and pervasively silicified bedded and dacitic tuffs. Additional surface samples in the 100–500 dU range (~0.1 – ~0.5 g/t Au estimated) across the same area at Wainikoro demonstrate the breadth of the gold-bearing footprint. Trench channel and point sampling returned values up to 1,446 dU (~1.45 g/t Au estimated) within silicified fault-controlled structures, with a 13-metre interval at TR26-011 averaging 275 dU (~0.28 g/t Au estimated) and point samples of 724 dU (~0.72 g/t Au estimated) at 14.5 m (TR26-011) and 701 dU (~0.70 g/t Au estimated) at 9 m (TR26-012). The strongest detectORE responses consistently sit at intersections of the NW–SE oblique fault network with the West-East Transfer Zone corridor and the segmented Nubu Graben margins. The newly identified in-situ chalcedonic vein, the adjacent silicified breccia, the other quartz veins listed in Table 1 and the trench-hosted channel and point samples are spatially clustered along these intersection points, reinforcing the interpretation of a coherent, structurally controlled hydrothermal system at Wainikoro.
