Project Overview

The Manga Metals Project is located in the highly prospective Oakover Basin, approximately 25 kilometres south-south-west of Consolidated Minerals’ Woodie Woodie operations.

​

  • Comprising 28 graticule blocks over an area of 89.6 km²

  • Similar geological setting to Woodie Woodie, with Pinjan Cherts and Carawine Dolomites transected by major fault structures hosting hydrothermal manganese

  • Initial funding allocated to heritage surveys and a resource assessment drilling program

Work Underway

The project is progressing through multiple stages of technical and environmental preparation:

​

  • Structural geology and hydrothermal manganese targeting through Sentinel-2 satellite analysis

  • Compilation of historical exploration data

  • Field studies and drill program planning

Exploration Strategy

Our exploration approach is carefully designed to maximise discovery potential:

​

  • Focus on high-grade hydrothermal manganese targets with structural evidence

  • Implementation of induced polarisation (IP) geophysics to identify subsurface mineralisation

  • Systematic drill testing to confirm hydrothermal Mn sources

  • Ongoing environmental and heritage surveys to ensure responsible development

Opportunity Summary

The Manga Metals Project offers an outstanding investment and development opportunity:

​

  • Rising demand for manganese, driven by its role in steelmaking and critical minerals supply chains

  • Geopolitical pressures potentially constraining global supply

  • A significant ground position in a world-class district within a secure mining jurisdiction

  • Prioritised exploration strategy with clear high-grade manganese drill targets
