Name of the Project
Butcherbird Stage 2 manganese expansion project.

Location
The project comprises eight known manganese mineral resources in an estimated 600 km2 of the southern Pilbara region, in Western Australia.

Project Owner/s
Manganese developer Element 25 (E25).

Project Description
Butcherbird comprises eight known manganese mineral resources.

The project is based on the extraction and processing of the Yanneri Ridge and Coodamudgi mineral resources and reserves. 

It builds on additional resource delineation conducted in June 2024 and an updated mineral resource estimate completed in October 2024, which increased measured and indicated resources at the deposits. 

The project, with an 18.3-year life-of-mine, will use 87% of measured resources and 77% of indicated resources within the Butcherbird resource base. 

The project proposes the expansion of the operation to 1.1-million tonnes a year of manganese concentrate. 

It will use expanded opencut mining methods, a modified primary comminution circuit and a dense-media separation back-end solution to optimise grade and recoveries.

The concentrate production strategy complements and enhances E25’s plan to develop a proposed high-purity manganese sulphate (HPMSM) plant, in Louisiana, in the US, to supply offtake partners General Motors and Stellantis with HPMSM for electric vehicle battery cathodes.
