G88 Energy Advances to 95% Stake in Leviathan Copper-Molybdenum Project with A$3 Million Investment

G88 Energy's Exploration Approach and Leviathan Project Acquisition Details

G88 Energy Limited focuses on exploring and developing mineral projects with strong commercial prospects. Its portfolio includes various mineral exploration interests, emphasizing deposits with economic viability through systematic exploration. Acquiring an interest in the Leviathan Porphyry Copper-Molybdenum Project strategically enhances the company's exploration pipeline, targeting a hydrothermal system within a well-established mining region.

Situated in Mohave County, Arizona, USA, the Leviathan Project benefits from a region known for copper and molybdenum mineralisation and established mining infrastructure. G88 Energy's interest is secured through an earn-in agreement with Golden Mile, allowing the company to earn up to 95% ownership by investing A$3 million in the project. This structure enables advancing exploration while managing capital across its portfolio. Arizona’s location places the project within a premier global copper-molybdenum mining district.

Sampling Programme Outcomes and Mineralisation Insights

The first-stage regional sampling involved collecting 110 rock chip and stream sediment samples across the Leviathan Project area. Assay results revealed widespread anomalous copper and molybdenum mineralisation, suggesting the hydrothermal system extends well beyond previously known zones. The sampling aimed to map mineralisation distribution linked to the Leviathan vein and identify additional vein structures within the project.

Results showed 72% of rock chip samples contained copper and molybdenum grades above 500ppm. Notably, 18 samples exceeded 1,000ppm copper, indicating high-grade mineralisation zones. These findings demonstrate robust, extensive mineralisation with multiple economically interesting zones across the area. The prevalence of elevated copper and molybdenum grades supports the presence of a significant porphyry copper-molybdenum system featuring multiple mineralised structures.

Leviathan Vein Features and Multi-Phase Breccia System

The Leviathan vein is the primary structural feature identified, characterized as a multi-phase northeast-trending breccia vein system. It sub-outcrops for roughly 800 metres with widths up to 6 metres, offering substantial scope for exploration and development. This geometry suggests a sizeable mineralised body warranting systematic follow-up exploration, including drilling. The vein’s northeast orientation aligns with regional structural trends in Arizona’s copper-molybdenum districts.

This multi-phase breccia system implies mineralisation formed through several hydrothermal episodes, creating varied mineral textures and grades within the vein. Multiple mineralised phases may indicate repeated fluid flow and mineralisation events, typical in porphyry systems where higher-grade zones can develop. The vein’s significant strike length and width present key drill targets for upcoming exploration, with potential extensions beyond mapped outcrops.

Extensive Anomalous Mineralisation and Broader Exploration Potential

Beyond the Leviathan vein, the sampling identified widespread anomalous copper and molybdenum mineralisation throughout the project, indicating multiple affected zones within the Leviathan boundary. This suggests additional vein structures exist, providing discrete targets for further exploration. The regional sampling approach effectively delineated the broader mineralised system and supports prioritising future drilling efforts.

Discovering additional vein structures expands the Leviathan Project’s exploration upside. The widespread anomalous mineralisation indicates a multi-vein hydrothermal system rather than a single feature, enlarging the target area. Future exploration may uncover more high-grade zones suitable for economic development. These initial results lay a strong foundation for follow-up drilling and refining exploration models.

Earn-In Agreement and Capital Investment Framework

The G88 Energy and Golden Mile earn-in agreement allows G88 Energy to acquire up to 95% interest by spending A$3 million on exploration and development. This commitment underscores management’s confidence in the project’s potential, as indicated by the initial sampling results. The earn-in aligns G88 Energy’s interests with project progression, requiring capital deployment to secure full ownership.

This structure offers G88 Energy capital flexibility across its portfolio while securing a major stake in a project with strong exploration prospects. The company has not disclosed the timeline or milestones for the expenditure commitment, providing optionality on capital deployment pace while advancing Leviathan.

Geological Context and Hydrothermal Porphyry System Characteristics

The Leviathan Project targets a hydrothermal copper-molybdenum system formed by heated fluid circulation within host rock. Hydrothermal porphyry systems are major global sources of copper and molybdenum ores. The project’s multiple northeast-trending multi-phase breccia veins align with typical porphyry mineralisation patterns, indicating repeated hydrothermal activity.

Arizona’s geological history includes significant porphyry copper-molybdenum mineralisation, with active and historic mines demonstrating deposit viability. This regional setting provides a model for understanding Leviathan’s mineralisation and its economic potential. The widespread anomalous mineralisation and Leviathan vein characteristics are consistent with porphyry systems known to host major deposits in the southwestern US.

Assay Grade Distribution and Importance of High-Grade Samples

Assay data shows 72% of rock chip samples exceed 500ppm copper and molybdenum, well above typical background levels, indicating extensive mineralisation beyond narrow veins. The 18 samples with over 1,000ppm copper highlight zones of concentrated mineralisation warranting priority drilling.

The distribution of high-grade samples across the project suggests typical porphyry grade variation, with higher-grade zones interspersed within lower-grade envelopes. This pattern aligns with the multi-phase breccia vein model and indicates mineralisation may extend below surface weathering. Drilling is expected to intersect elevated copper and molybdenum zones, supporting economic ore body potential.

Upcoming Exploration Plans and Future Steps

The initial sampling programme sets the stage for follow-up exploration at Leviathan. While specific drilling timelines or scopes have not been disclosed, the anomalous mineralisation and Leviathan vein geometry provide clear targets for systematic drilling. Priorities will likely focus on areas with highest copper and molybdenum grades and the main vein structure.

Next milestones include designing and executing drilling to test the Leviathan vein and other identified vein structures. Details on drilling metres or schedules remain undisclosed. Drilling results will clarify mineralisation depth, grade consistency, and economic potential, guiding resource estimation and development decisions.

Exploration Risks and Uncertainties

Early-stage exploration projects like Leviathan carry inherent risks regarding discovery of economically viable deposits. Although initial sampling shows widespread anomalous mineralisation, drilling may not confirm sufficient grade or tonnage for mining. No drilling results have been released, so mineralisation depth and continuity remain unknown. Investors should consider exploration risk as capital may not yield economic discoveries.

Specific risks include geological uncertainties about mineralisation extent, operational challenges in Arizona, and market fluctuations in copper and molybdenum prices. G88 Energy’s ability to earn full 95% interest depends on meeting the A$3 million expenditure and potentially securing further funding for resource development. Regulatory and permitting risks in Arizona, though generally manageable at exploration stage, could affect timing and scope.
