Kalo Gold Completes First Phase Drilling and Continues Field Program at Vatu Aurum Project, Fiji

01.10.2025  |  ACCESS Newswire

VANCOUVER, October 1, 2025 - Kalo Gold Corp. (TSXV:KALO) ("Kalo" or the "Company") announces completion of the first phase of drilling and the continuation of field programs at its 100%-owned 367 km² Vatu Aurum Project, Fiji. Phase 1 tested an initial subset of the more than 25 high-priority targets defined across the Aurum Epithermal Field, which hosts both vein-hosted and diatreme/surge-related epithermal gold. Assays are pending, with initial results expected in mid-October 2025.

Key Takeaways

• Vatu Aurum hosts two complementary gold systems: epithermal gold target corridors (Namalau, Loma, Buca) and volcanic breccias (diatremes) at Qiriyaga - styles that in similar Pacific Rim deposits have supported both high-grade and bulk-tonnage gold mineralization (no economic comparison is implied).

• Phase 1 drilling tested only 4 of 25+ defined targets, meaning the majority of the Aurum Epithermal Field remains untested.

• The geology indicates the Namalau Trend is interpreted to be a well preserved epithermal system, while at the Qiriyaga Complex, where several historical resource estimates and more than a dozen newly identified diatremes highlight potential for both shallow and deeper gold mineralization (*see Historical Estimate Disclaimer).

• Assays expected mid-October will provide the first test of gold tenor and continuity, guiding follow-up drilling.

Two Distinct Mineralization Styles at Aurum Prime

Phase 1 drilling, trenching, and mapping have provided important geological context, supporting the interpretation that Aurum Prime hosts two distinct mineralization styles.

Epithermal Vein-Hosted Systems - Namalau, Loma & Buca Trends

• Structurally controlled quartz veins and hydrothermal breccias - essentially fracture zones where gold-bearing fluids deposited quartz and breccia bodies.

• Pathfinder anomalies (Se, As, Sb, Hg, Tl) are consistent with a fertile low-sulphidation epithermal system.

• Preservation of surface sinters, bladed quartz, and silica flooding indicates limited erosion and supports the interpretation of a vertically intact epithermal profile.

• Geological features are consistent with vein systems such as the Martha Mine in Waihi, New Zealand, where narrow veins observed at surface were later shown to connect into broader mineralized zones at depth, though no resource or economic comparison is implied.

Diatreme/Surge Systems - Qiriyaga Complex

• Reinterpreted as a preserved diatreme system with an epithermal overprint - essentially a volcanic vent filled with explosive breccias that were later mineralized by gold-bearing fluids.

• Mineralization occurs both in the breccia matrices and in pyroclastic surge horizons around the vent.

• Earlier work defined five diatreme centers (QC1-QC5); mapping now identifies more than a dozen centers, the majority of which remain untested.

• Historical drilling and multiple past resource estimates demonstrated both broad zones and localized high-grade shoots. Reinterpretation suggests earlier work only sampled the shallow preserved portion of a system that is both vertically and laterally extensive (*see Historical Estimate Disclaimer below).

• For geological context, features are consistent with preserved maar-diatreme systems such as Kelian (Indonesia) and Balatoc (Philippines), which demonstrate how preserved maar-diatreme settings can host both bulk-tonnage breccia gold and structurally focused high-grade mineralization, though no resource or economic comparison is implied.

Together, these styles reinforce that Vatu Aurum is a large system with multiple mineralization pathways preserved and only a fraction tested to date.

"Our exploration to date supports the interpretation of two mineralization styles at Vatu Aurum - vein-hosted systems at Namalau, Loma, and Buca Trends, and diatreme/surge-related mineralization at the Qiriyaga Complex. The Namalau Trend is interpreted to be a well-preserved epithermal system, while Qiriyaga builds on several historical resource estimates and newly identified diatremes that remain largely unexplored. Together, these reinforce our view that we are advancing a vertically intact, large-scale system. With assays pending and additional drilling planned, we are well-positioned to create meaningful value for our shareholders." - Terry L. Tucker, P.Geo., President & CEO.

Exploration Progress

The 2025 exploration program continues to advance systematically across multiple targets within the 367 km² Vatu Aurum Project. Field operations have been executed safely and efficiently, with zero lost-time incidents (LTIs) recorded year-to-date. Completed work includes:

Next Steps

• Report pending assays from Phase 1 drilling, with initial results expected in mid-October.

• Report Aurum Prime trench results.

• Report Wainikoro, Coqeloa and Aurum Prime soil results.

• Step out at Namalau Trend to drill test feeder structures at depth and along strike, while expanding into the untested corridors at Loma and Buca Trends.

• Advance Qiriyaga Complex testing with additional drilling of breccia-hosted targets guided by the new diatreme framework.

• Expand systematic testing of the 25+ high-priority targets, the majority of which remain untested, supported by trenching and mapping to bring additional zones to drill-ready stage.

• Deploy a Portable PPB detectORE™ unit to generate near real-time gold data, accelerating targeting decisions and reducing reliance on external assay turnaround.

• Integrate multi-dataset vectoring (soils, trenches, TerraSpec, XRF, ICP, geophysics and geological relogging) to refine structural controls and prioritize feeder zones.

Together, these geological observations and the work completed to date position Kalo to advance from initial testing toward unlocking the broader district potential.

Exploration activities remain on schedule and aligned with the 2025 strategy, with Phase 1 drilling and trenching providing valuable geological context. Results to date support the interpretation of a vertically preserved epithermal system at Aurum Prime, alongside diatreme-related mineralization at the Qiriyaga Complex. Together, these observations reinforce the scale potential of Vatu Aurum as a multi-corridor, multi-target district.

Initial assays, expected in early to mid-October, will provide the first opportunity to evaluate gold tenor and continuity across feeder zones and breccia targets. Follow-up drilling is anticipated to test deeper structures and expand mineralization along the Namalau Trend and within the Qiriyaga Complex.

With assays pending, field verification ongoing, and vectoring continuing, Kalo is well positioned to advance its most prospective targets into the next phase of drilling. With more than 25 identified targets and only a fraction drill-tested, the current program represents just the beginning of unlocking the full scale of the Aurum Epithermal Field.

*Historical Estimate Disclaimer

The Qiriyaga Complex (Qiriyaga Hill and Vuinubu Ridge Gold Deposits) have been the subject of several historical mineral resource estimates completed between 1991 and 2017. These estimates are considered historical in nature and do not conform to current CIM Definition Standards or NI 43-101 reporting requirements. A Qualified Person has not done sufficient work to classify these historical estimates as current mineral resources, and Kalo Gold is not treating them as current resources. Additional drilling and technical studies would be required to verify and update any historical estimate.

** Comparison with Kelian and Balatoc

Analogue Context: Diatreme-Epithermal Gold Systems

For geological context, the Qiriyaga Complex shares key geological features with other diatreme-epithermal gold systems in the Pacific Rim, most notably the Kelian Deposit in Indonesia and the Balatoc Diatreme in the Philippines.

At Kelian (East Kalimantan, Indonesia), mineralization was hosted within maar-diatreme breccias and hydrothermal breccias. Before mining commenced, Kelian contained reserves of ~55 Mt at an average grade of 3.2 g/t Au, including localized high-grade zones >10 g/t Au. Between 1992 and 2004, the operation produced ~5.75 Moz of gold and ~4.66 Moz of silver. Mineralized breccias extended to depths of >600 m, with gold occurring both as broad zones of disseminated breccia-hosted mineralization (typically 1-2 g/t Au) and as structurally focused high-grade shoots localized along breccia contacts and splays.

At Balatoc (part of the Acupan system, Baguio District, Philippines), historical records indicate that Acupan as a whole produced more than 6.4 Moz of gold at an average grade of ~6 g/t Au. Within the Balatoc diatreme itself, past estimates outlined 2.5-4.0 Mt at ~3.8 g/t Au cut-off, with reported grades ranging from 4-30 g/t Au in vein zones and up to 12.6 g/t Au in breccia-hosted bodies.

While Qiriyaga is still at an early stage and no mineral resources have been defined, these analogues demonstrate how preserved maar-diatreme systems can host multimillion-ounce gold deposits, with a combination of bulk-tonnage breccia mineralization and structurally focused high-grade zones. This provides valuable geological context and underscores the scale potential of the Qiriyaga Complex within the Aurum Epithermal Field.

Cautionary Note on Analogues

The Kelian and Balatoc deposits are referenced strictly for geological context and exploration targeting purposes. The production figures, grades, and tonnages cited are historical in nature and are not intended to imply that similar results will be realized at the Vatu Aurum Project. The Qiriyaga Complex is at an early stage of exploration and no mineral resources or reserves have been defined under NI 43-101. Further drilling, sampling, and technical studies are required to determine the presence of any mineral resources at Qiriyaga.
