Geological Setting
Located in the Nubu Graben back-arc basin, the project hosts intact, high-grade epithermal gold systems. This dynamic environment has produced 25 high-priority gold targets within the broader Aurum Epithermal Field, including the geologically distinct and high-grade Qiriyaga Complex — a maar-diatreme system now recognized as an important structural and mineralizing center of the project.

Exploration Strategy & Drill Program
The Namalau Trend hosts a fully preserved epithermal gold system with significant discovery potential. Despite historical high-grade results, much of the system remains untested. Our upcoming up to 9,000-meter drill campaign is designed to systematically evaluate key upwelling zones, advance priority targets, and unlock the trend’s full potential. This program represents a major step forward in unlocking the Namalau Trend’s gold resources through modern exploration techniques.

Compilation and Model Development (2023–2025)
Led by SGDS Hive
In mid 2023 to mid 2024, Kalo Gold, under the direction of Andy Randell, P.Geo. (SGDS Hive), completed a transformative reinterpretation of the Vatu Aurum Project. This marked the first comprehensive integration of more than 30 years of geological, geochemical, and geophysical data across the full 367 km² tenement area.
Using a suite of advanced tools — including structural lineament analysis, multi-element geochemical clustering, alteration zonation, and 3D inversion modeling of CSAMT and airborne magnetic data — the team constructed a new district-scale geological framework for the Aurum Epithermal Field. This model revealed the potential for vertically preserved mineralized systems and expanded the project's exploration footprint both laterally and at depth.
Systematic Approach
Our exploration is data-driven, integrating historical data, modern geophysics, detailed mapping, and geochemical surveys.

Comparison to Major Pacific Rim Deposits
Vatu Aurum shares key geological features with major Pacific Rim epithermal systems, notably the Martha Mine (New Zealand) and Kelian (Indonesia). These analogues provide exploration context only and do not imply potential resources or economic viability.

Epithermal Gold System Zonation: From Surface Clues to Bonanza Gold
Epithermal gold systems form when hot, metal-rich fluids rise from deep in the Earth and interact with volcanic rocks. These systems develop distinct vertical zones, each with its own geochemical and mineralogical fingerprint — helping explorers like Kalo Gold target high-grade gold at depth.

+Se and –K in Soils: What It Means for Exploration
Elevated selenium (+Se) and depleted potassium (–K) in soils are powerful geochemical indicators of a gold-fertile, vertically preserved epithermal system. +Se reflects evolved hydrothermal fluids that underwent extensive boiling, while –K indicates acidic alteration from fluid-rock interaction near the paleo-surface. Together, they not only vector toward bonanza-grade Au–Ag mineralization, but also suggest that the system is deep-rooted, with a strong magmatic heat source — increasing the potential for large-scale gold discovery at depth.

Combined +Se / –K Signature
· Defines a gold-fertile system, capable of hosting bonanza-grade mineralization.
· Marks a preserved vertical profile, ideal for targeting feeder zones with high-grade Au–Ag at depth.
· Acts as a reliable vector for drilling in low-sulfidation epithermal belts with magmatic influence.
The presence of Se-rich minerals and potassium depletion near surface strongly suggests that the Vatu Aurum system is vertically preserved and sourced from deep, magmatic fluids. This deep-rooted architecture, combined with evidence of boiling and alteration zonation, indicates a robust gold-fertile system with potential for significant mineralization at depth.
