Bali Project

A High-Potential Critical Minerals and Gold Target in the Eastern Goldfields

The Bali Project is one of Greta Minerals Australia Ltd’s flagship exploration assets, strategically located in the heart of Western Australia’s Eastern Goldfields, an area globally recognized for its rich lithium and gold endowment.

Covering nearly 300 km² of highly prospective terrain, the Bali Project lies within a structurally complex and geologically fertile corridor shaped by significant granitic intrusions and greenstone sequences. The project has been targeted for both critical minerals (notably lithium-caesium-tantalum pegmatites) and gold, reflecting its dual-mineral potential and strong alignment with regional exploration trends.

Geological Highlights

The project area is geologically anchored by two major fertile granitic intrusions—part of the post-regional folding “Bali Suite” granitoids—widely considered prospective for hosting lithium-bearing pegmatites. These granites are in direct contact with north to northeast-trending greenstone belts, including basaltic and ultramafic rocks, providing the ideal geological environment for both pegmatite intrusion and gold mineralization.

Key structural features include:

Multiple northwest- and north-northeast-trending shear zones, similar to those controlling mineralization at the nearby Mount Marion lithium mine, operated by Mineral Resources Ltd.

The Kunanalling Shear Zone, an interpreted influence on local faulting and fluid migration pathways.

Mapped anticlinal structures and quartz-rich reefs near granite-greenstone contacts—areas known to host mineralized pegmatites in similar deposits regionally.

Early Exploration Indicators

Initial exploration has yielded promising indicators:

Soil geochemistry surveys using CSIRO/LabWest’s advanced UltraFine+™ technique revealed lithium anomalism peaking at 266 ppm Li, along with elevated caesium and rubidium values.

These anomalies occur along the contact zone between komatiite and fertile monzogranite, consistent with known LCT pegmatite emplacement models.

The anomalous lithium zone extends across a broad corridor up to 600m x 400m, suggesting a substantial pegmatite system.

Additionally, historic gold exploration intersected multiple high-grade gold intervals exceeding 1 g/t Au, further supporting the area’s dual mineralisation potential.

Strategic Outlook

The Bali Project shares striking geological parallels with some of Western Australia’s most

significant lithium and gold deposits, including:

Mount Marion (lithium)

Granny Smith, St Ives, and Paddington (gold)

With a combination of fertile source granites, structurally prepared greenstone sequences, and validated geochemical anomalies, Greta Minerals is well positioned to advance the Bali Project through targeted exploration that preserves geological integrity while unlocking long-term value.
