A high-potential manganese exploration opportunity located in the Pilbara region of Western Australia.
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 
​

Tenement details.
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 
​

MC Hammer field testing.
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
