VANCOUVER, BC / ACCESS Newswire / June 30, 2026 / Kalo Gold Corp. (TSX-V:KALO)(OTCID:KLGDF)(FSE:9M51) ("Kalo", "Kalo Gold" or the "Company") is pleased to report geochemical and mineralogical results from two reconnaissance drill holes VA26-DH18 and VA26-DH19 completed at Wainikoro within its 100%-owned Vatu Aurum Project.

The two wide-spaced (1,027 m) reconnaissance drill holes were designed to test the potential for gold mineralisation associated with regional faulting, hydrothermal brecciation, elevated arsenic and epithermal pathfinder geochemistry and coincident geophysical anomalies identified at Wainikoro. Results from both holes confirm the presence of anomalous gold associated with fault-controlled quartz veins and continue to support the Company's interpretation that Wainikoro represents a structurally controlled epithermal gold system. These reconnaissance holes were drilled as geological vectoring holes, intended to advance the geological model, improve the Company's understanding of the scale of the system and guide future drill targeting.

Highlights

• VA26-DH19 intersected multiple low-grade gold-bearing quartz veins within a broad hydrothermal system.

• Gold-bearing veins found at surface are associated with elevated arsenic and antimony, characteristic of high-level epithermal systems.

• QEMSCAN (Quantitative Evaluation of Minerals by Scanning Electron Microscopy) analysis identified arsenopyrite replaced by pyrite pseudomorphs, interpreted as an early mineralizing phase.

• VA26-DH18 returned anomalous gold values associated with elevated arsenic within hydrothermal breccias and fault zones.

• Surface sampling from quartz veins and hydrothermal breccias surrounding VA26-DH18 returned detectORE^™ values up to 1,920 dU (~1.92 g/t Au estimated).

• Results demonstrate that gold-bearing hydrothermal activity extends across the 1.8-kilometre-long Wainikoro magnetic-low target, one of several identified within the broader district.

• Ground geophysical survey (CSAMT, IP and gravity) will be completed by Fender Geophysics Pty Ltd at Wainikoro, scheduled to commence in mid-July 2026 to refine drill targeting.

CEO Commentary

Terry L. Tucker, P.Geo., President and CEO of Kalo Gold, commented: "These results strengthen our confidence that Wainikoro is a structurally controlled, multi-stage hydrothermal gold system developed along the Nubu Graben corridor. The widespread alteration, multi-stage quartz veining, strong arsenic and mercury pathfinder signature, and arsenopyrite-related mineralization all support the presence of a fertile epithermal system. Importantly, mineralization intersected in VA26-DH18 demonstrates that gold-bearing hydrothermal activity extends beyond the main 1.8-kilometre magnetic-low target, highlighting the potential for multiple mineralized centres across the broader Wainikoro area. With gold-bearing quartz veins now confirmed in drilling, the integration of drilling, airborne magnetics and the planned CSAMT, IP and gravity surveys will allow us to prioritize and target future drilling with significantly greater precision as we continue to evaluate the scale and architecture of the Wainikoro epithermal system."

VA26-DH19 - Kope Road North

Drill hole VA26-DH19 (270.6 m) was designed to test the eastern extent of a 1.8-kilometre-long coincident magnetic low and arsenic-in-soil anomaly previously reported by the Company. The hole was oriented to intersect the principal bounding fault of the Nubu Graben, a major structural corridor interpreted to have focused hydrothermal fluid flow.

The drill hole intersected extensive hydrothermally altered andesitic breccias from 75.6 m to 188.5 m before crossing the interpreted Nubu Graben-bounding fault zone at approximately 268 metres depth.

This altered interval contains dispersed quartz veins and distinctive lath-shaped sulphide crystals. These quartz veins are consistently associated with elevated arsenic and antimony values, a geochemical association commonly observed in the upper levels of epithermal gold systems.

VA26-DH19 cross-section (Wainikoro) showing the drill hole through hanging-wall andesite, basalt flows and minor volcaniclastics, a sulphide-bearing quartz-carbonate vein zone returning 1.5 m at 1.61 g/t Au (150.0-151.5 m), the Nubu Graben Fault and the footwall breccia zone in andesites.

Fire assays (and dU values) from individual intervals returned:

*Where gold is hosted within sulphide minerals, the on-site crushing and leaching process of the detectORE^™ system does not fully liberate all the gold prior to analysis, resulting in dU values that underestimate fire assay grades in these intervals.

QEMSCAN analysis of selected sulphide-bearing vein samples, completed at Intertek (Kamloops, Canada), indicates that the lath-shaped sulphide crystals were likely originally arsenopyrite and were subsequently replaced by pyrite, preserving their original crystal morphology as pseudomorphs. The presence of arsenopyrite is considered significant, as it may represent an early mineralizing phase associated with gold deposition within the hydrothermal system.

VA26-DH18 - Kope Road South

Drill hole VA26-DH18 (245.7 m), drilled at Kope Road South prior to the airborne magnetic survey, returned anomalous gold mineralization associated with elevated arsenic in hydrothermal breccias and fault zones. Associated trench and surface samples returned detectORE^™ values up to 1,920 dU (~1.92 g/t Au estimated; see Technical Notes on detectORE™ Gold Screening Results). The hole demonstrates that gold-bearing hydrothermal activity extends beyond the main Wainikoro magnetic-low target.

Fire assays from brecciated and faulted intervals returned:

*Where gold is hosted within sulphide minerals, the on-site crushing and leaching process of the detectORE™ system may not fully liberate all the gold prior to analysis, resulting in dU values that underestimate fire assay grades in these intervals.

Geological Interpretation

Results from both drill holes support the interpretation that Wainikoro hosts a structurally controlled hydrothermal system centred on the Nubu Graben fault corridor. Surface mapping and detectORE^™ sampling at Wainikoro indicate that gold-bearing veins occur on multiple orientations - E-W, NE-SW and NW-SE - with the strongest responses where these structural trends intersect.

The association of gold with elevated arsenic and antimony, together with the widespread occurrence of hydrothermal brecciation, silicification, faulting, and arsenopyrite-bearing veins, suggests the Company may be exploring the upper levels of an epithermal gold system.

Detailed logging and petrographic review of VA26-DH19 further support this interpretation. The hole intersected a significant volume of intense clay (illite-dominant, with subordinate chlorite) and silica alteration, together with at least three generations of quartz veining - early quartz-hematite veins, cut by quartz-carbonate-pyrite veins, and later quartz ± carbonate veins - consistent with long-lived, multi-pulse hydrothermal activity. The hole also intersected coherent andesite, a competent host rock favourable for the development of continuous quartz veins.

Importantly, mineralization identified in VA26-DH18 demonstrates that gold-bearing hydrothermal activity extends beyond the currently defined magnetic-low target, highlighting the potential for multiple mineralized centres across the broader Wainikoro area. Consistent with the Company's measured, data-led approach, the next phase of drilling will follow integration of the recently completed airborne magnetic and radiometric survey and the planned ground geophysics into the project-wide exploration model.

The Company has engaged with Fender Geophysics Pty Ltd to complete a CSAMT, IP and Gravity ground geophysical survey at Wainikoro with work scheduled to commence mid-July, subject to any import requirements and crew scheduling requirements.

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 by the Company in 2025 on 824 Vatu Aurum samples showed a strong correlation between dU and certified Fire Assay (Pearson R = 0.98 for drill core; R = 0.96 for trench samples). Soil dU has not been directly validated against Fire Assay, and the relationship is variable and influenced by lithology, mineralogy and sample preparation. Where gold is hosted within sulphide minerals, the on-site crushing and leaching process of the detectORE^™ system does not fully liberate all gold prior to analysis, resulting in dU values that underestimate fire assay grades in these intervals. Any approximate equivalence (e.g. ~1,000 dU ≈ ~1 g/t Au) is for contextual reference only and must not be relied upon for grade estimation. See the Company's news release dated 24 February 2026 for full details.
