Star Metro - Kalo Gold Defines Kilometre-Scale Epithermal Gold Targets and Structural Corridors at Wainikoro Within a 40 km Gold Corridor, Vatu Aurum, Fiji

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.

Wainikoro: Two Exploration Drill Holes Complete; Kilometre-Scale Epithermal Targets Defined

Exploration 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 Exploration

Wainikoro 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 into the exploration model.

CEO Commentary

Terry L. Tucker, P.Geo., President and CEO of Kalo Gold, commented:

"Wainikoro is behaving the way a large epithermal system should behave at this stage of exploration. We have kilometre-scale arsenic anomalies at surface and now textural evidence in drill core that DH19 has intersected the upper levels of a boiling zone.

Over the coming months, pending Fire Assay results and the airborne magnetic survey will define where we drill next. Our surface-led approach is working: it is focusing capital on the most prospective structural corridors across a 40 km gold corridor that is, stage by stage, revealing itself."

Detailed Geological Information

KRN: Drillhole VA26-DH19

Drillhole VA26-DH19 (270.6 m) was completed at the eastern extent of the KRN target (Figures 1 and 3), intersecting brecciated andesitic volcanics with quartz veining and sulphide mineralization within a >1 km arsenic-in-soil anomaly, above 20 ppm As contour, along a Nubu Graben-related fault. detectORE™ soil values reach 1,640 dU (~1.64 g/t Au) and trench results include 1.73 g/t Au from hydrothermal breccia and 32 m @ 0.56 g/t Au (including 12 m @ 1.0 g/t Au) (historical trench TR17-5K05*). Core logging defines a multi-stage paragenetic sequence:

• Early iron oxide veining

• Main-stage quartz-carbonate veining

• Interpreted bladed carbonate, now replaced by quartz and sulphide pseudomorphs (sulphide characterization pending confirmation)

• Sulphide mineralization, includes arsenic-bearing phases

The presence of interpreted bladed carbonate is consistent with boiling and pressure fluctuations - key processes associated with gold deposition in epithermal systems. Elevated arsenic and antimony with low base metals support the interpretation that drilling intersected the upper levels of a vertically zoned epithermal system. Samples have been submitted for QEMSCAN (Quantitative Evaluation of Minerals by Scanning Electron Microscopy). Assays are pending. (*see NR 27 October 2025)

Figure 1: KRN - KRS Targets

VA26-DH19-10: Open-spaced quartz-carbonate vein hosted within a polymictic, chlorite-altered breccia. Interpreted bladed carbonate (calcite), partially replaced by quartz and sulphide pseudomorphs, post-date initial vein formation and are consistent with boiling and pressure fluctuations during hydrothermal fluid flow. Open-space (vuggy) textures with euhedral crystal growth indicate open-channel deposition along a dilational structure.

KRS: Drillhole VA26-DH18

KRS is located approximately 750 m southwest of KRN along a splay structure interpreted to represent a parallel structural corridor, provisionally interpreted as a Riedel shear within the same hydrothermal system (pending structural confirmation from the planned high-resolution airborne magnetic survey). The target area is characterized by a series of low, dome-shaped hills, interpreted to represent zones of intense silicification and hydrothermal alteration which have increased resistance to erosion.

Trenching returned 24 m @ 1.0 g/t Au (including 2 m @ 3.41 g/t Au) (historical trench TR13-5K04*). Soil geochemistry defines a coincident arsenic-in-soil anomaly directly associated with both trench-hosted mineralization and anomalous gold values, detectORE™ screening values up to 1,322 dU (~1.32 g/t Au), reinforcing the prospectivity of the target.

Drillhole VA26-DH18 (245.7 m) intersected polymictic breccias, quartz-carbonate veining, and sulphide mineralization consistent with a hydrothermal system. Assays are pending (*see NR 27 October 2025).

Expanding Target Pipeline

Additional targets continue to emerge across Wainikoro:

• NRC (Figure 2), approximately 1.5 km northwest of KRN: 1000 m by 530 m arsenic-in-soil anomaly with rock grab samples up to 0.6 g/t Au; follow-up fieldwork ongoing to expand the geological understanding of this target

• WKW: additional 300m by 200m arsenic-in-soil anomaly follow-up work ongoing

• Navialoa (NAG): expanding soil coverage over a magnetic low identified in regional historical TMI airborne geophysics and a possible circular feature in LiDAR

Structural Controls and System Interpretation

Integration of LiDAR, geophysics, and mapping has refined the structural model highlighting dilation zones at structural intersections - where N-S to NW-SE faults intersect the NE-trending Nubu Graben. These create localized areas of dilation and structural complexity which is a key control on fluid flow.

The combination of:

• interpreted boiling-related textures (bladed carbonate)

• multi-stage sulphide mineralization with evident arsenic enrichment

• strong structural controls on fluid flow

• widespread hydrothermal alteration and brecciation

• NE-SW trending graben architecture (Nubu Graben)

• cross-cutting N-S to NW-SE structures

• flexures and fault intersections that create zones of dilation

These observations support the interpretation of a structurally controlled epithermal system. VA26-DH19 is interpreted to have intersected the upper levels of this epithermal system.

Next Steps

• Receipt and interpretation of Fire Assay results (VA26-DH18 and DH19)

• Additional trenching across priority structural targets

• Expansion of soil geochemistry

• A high-resolution airborne magnetic and radiometric survey is now mobilized and will provide critical data to refine the structural framework and its connection to the broader Vatu Aurum corridor.

• Continued integration of geological, geochemical, and geophysical datasets to refine drill targeting

Taken together, these activities will continue advancing the geological model at Wainikoro and refining drill targeting and advancing priority targets toward drill testing through the remainder of 2026.

Technical Notes on detectORE™ Gold Screening Results

This news release references gold (Au) values reported in detectORE™ Units ("dU"), generated using the detectORE™ field-based gold analysis system developed by Portable PPB Pty Ltd. dU values represent a semi-quantitative, ppb-equivalent measure of leachable gold response and are used for exploration screening purposes only. They are not a direct measure of total gold content and are not equivalent to certified Fire Assay results. Accordingly, dU results are not used to estimate Mineral Resources or Mineral Reserves.

Internal validation work conducted by the Company in 2025 on 824 samples from the Vatu Aurum Project demonstrated a strong correlation between dU values and certified Fire Assay results (Pearson R = 0.98 for drill core; R = 0.96 for trench samples). Soil dU results have not been directly validated against Fire Assay. While a positive relationship exists, it is variable across different ranges and may be influenced by lithology, mineralogy, and sample preparation. Any approximate equivalence (e.g., ~1,000 dU ≈ ~1 g/t Au) is provided for contextual reference only and should not be relied upon for grade estimation. For full details, refer to the Company's news release dated 24 February 2026.
