Kalo Gold Updates Structural and Geological Model at Vatu Aurum Project, Fiji

VANCOUVER, BC / ACCESS Newswire / May 27, 2026 / Kalo Gold Corp. (TSXV:KALO)(OTCID:KLGDF)(FSE:9M51) ("Kalo", "Kalo Gold" or the "Company") is pleased to announce an updated structural and geological interpretation for its 100%-owned Vatu Aurum Project on Vanua Levu, Fiji. The updated interpretation integrates recently acquired LiDAR topography, surface mapping, the 2026 lineation survey, the high-resolution airborne magnetic survey, and historical regional geophysical datasets, and supports a refined exploration-targeting framework for the project. KEY HIGHLIGHTS Updated interpretation frames the Vatu Aurum Project as a single, multi-phase, structurally reactivated volcanic complex, integrating early intrusive and diatreme activity, regional extension, oblique faulting, and a hydrothermal overprint into one coherent geological model.

West-East Transfer Zone ("WETZ") - an interpreted regional accommodation corridor expressed as a continuous magnetic low, interpreted to link segmented fault systems across the project area and to act as a first-order control on fluid migration. Nubu Graben reinterpreted as segmented, en-echelon, and locally offset rather than continuous, producing relay zones and step-overs interpreted as prime dilation sites. NW-SE oblique fault network - interpreted as the dominant gold-hosting structural grain on present interpretation, with mapped gold-in-soil anomalies and recent trenching results aligning with this orientation.

Coastal belt of arcuate volcanic features interpreted as caldera-related centres, potentially representing a deeper magmatic source for hydrothermal fluids. Wainikoro target defined by coincident magnetic low and arsenic-gold soil anomaly, located within dilational structures linked to the WETZ. Updated targeting focus on intersections of the NW-SE oblique faults with the WETZ and the Nubu Graben, and on the interaction of structural intersections with the Qiriyaga vent field.

Recently completed 6,212 line-kilometre high-resolution airborne magnetic survey, flown at 100 m line spacing with infill at 50 m over priority areas, is expected to refine the definition of structural features at the project scale and improve targeting precision. Figure 1 - Vatu Aurum Structural Model Management Commentary Terry L. Tucker, P.Geo., President and Chief Executive Officer of Kalo Gold, commented: "The most important interpretive shift in this update is the recognition that Vatu Aurum behaves as a single, multi-phase, structurally reactivated volcanic complex rather than as a series of separate prospects. That reframing - combined with the high-resolution airborne magnetic survey and the active programme of trenching, traverse mapping, and soil-grid expansion across the Wainikoro area - gives us a much sharper and more defensible framework for prioritising the next phase of exploration and targeting.

The Updated Interpretation On the integration of LiDAR topography, the 2026 lineation survey, surface mapping, and the project's evolving geophysical and geochemical datasets, the Company now interprets the Vatu Aurum Project as a single, multi-phase, structurally reactivated volcanic complex rather than as a series of separate prospects. The interpretation comprises four overprinting elements that the Company believes together control the location of gold mineralisation across the project area: early intrusive and diatreme activity that created radial fracture permeability and established the Qiriyaga vent field and equivalent vent structures; regional extension that formed the Nubu Graben as a segmented, en-echelon system; subsequent oblique NW-SE faulting that cut the graben and reactivated earlier structures, creating relay ramps, pull-aparts, and dilation zones; and a hydrothermal overprint that exploited both the early diatreme-related permeability and the later structural intersections. Key Structural and Volcanic Elements At the regional scale, the Company has defined a broad east-west trending structural corridor referred to as the West-East Transfer Zone ("WETZ").

The WETZ is expressed geophysically as a continuous magnetic low - observed in the historical AusAID dataset and increasingly resolved in the ongoing high-resolution airborne magnetic survey - and is interpreted as a long-lived accommodation corridor linking segmented fault systems across the project area. Superimposed on the WETZ corridor is the Nubu Graben, which the updated interpretation describes as structurally segmented, en-echelon, and locally offset rather than a single continuous structure. The Company further interprets a network of NW-SE oblique faults, Riedel shears, P-shears, and minor transfer faults that cut across the graben and align with mapped gold-in-soil anomalies and recent surface trenching results.

On the integrated dataset, this NW-SE oblique fault network is interpreted to perform the dominant structural work hosting gold mineralisation at Vatu Aurum, with the highest fracture density and dilation expected at intersections of the oblique fault network with the WETZ and with the graben margins. A coastal belt of arcuate volcanic features identified in the LiDAR and lineation datasets is interpreted as a zone of caldera-related volcanic centres, considered to reflect a deeper magmatic control on the project and a potential source for hydrothermal fluids. At a more localised scale, the Qiriyaga Complex is interpreted to host approximately fourteen potential diatreme and breccia-pipe structures within an approximately 1 km × 1 km zone proximal to the Company's camp, with additional candidate vent structures identified at 1K and Vunisea.

The spatial relationship between the caldera belt, the WETZ corridor, the NW-SE oblique fault network, and the Qiriyaga vent field is interpreted to record a vertically integrated mineral system, with magmatic fluids channelled into structurally favourable zones at depth and subsequently focused into dilational sites at shallower structural levels. Targeting Implications The updated interpretation refines the Company's targeting framework. Highest-priority ground is interpreted to occur at intersections of the NW-SE oblique faults with the WETZ and with the Nubu Graben, particularly where those intersections occur at or near the margins of interpreted caldera-related features.

Parallel splays to the graben, step-over relay zones, and the inter-prospect corridor between Aurum Prime and Wainikoro are considered secondary-priority targets where structural grain is interpreted to continue but where existing geochemical coverage remains incomplete. Continuous, straight fault segments lacking structural complexity are considered lower priority. Refinement Through High-Resolution Airborne Magnetic Survey The current interpretation is supported by regional geophysical datasets including the historical AusAID magnetic data, which provide valuable regional context but are relatively low resolution.

The Company's 6,212 line-kilometre high-resolution airborne magnetic survey is complete - was flown at 100 m line spacing with infill at 50 m over priority target areas - is expected to materially enhance the definition of structural features at the project scale, allowing for more precise mapping of intersection geometries, fault traces, and prospective zones identified in the updated interpretation. Final processed datasets will be integrated with existing geological and geochemical data to support the next phase of exploration and targeting on the project.
