Pinnacle is building a portfolio aligned with surging demand for electrification, defence materials, and battery technologies. Antimony, lithium and rare earths are all on global critical minerals lists, and Pinnacle’s North American and Australian footprint provides a strong foundation for long-term growth.

 — rapidly emerging as a major critical minerals hub; home to historic antimony and gold mines and supportive permitting frameworks.

 — one of the world’s most active and well-understood lithium exploration districts.

South Australia & Western Australia (Australia)

 — globally competitive jurisdictions with excellent infrastructure and strong ESG baselines.

This geographic spread reduces jurisdictional risk and increases optionality.

Across all projects, Pinnacle has well-defined exploration pathways:

Lightning Peak restart assessment underway (mapping, sampling, modelling).

Multiple new drill targets emerging at Thunder Mountain from geophysical interpretation.

Field exploration planned at Adina East to validate high-priority lithium targets.

Metallurgical review and further REE assessment at Wirrulla.

Ongoing mineralogical studies and JV discussions at Capel HMS.

Each of these workstreams provides material news flow potential.

Pinnacle Minerals is advancing a diversified portfolio of critical mineral projects positioned for long-term global demand. With exploration progressing across multiple jurisdictions, we are focused on delivering sustainable value for shareholders.
