Development
Development

Our success is underpinned by our commitment to growing in a sustainable manner. Developing projects involves two critical stages in the mining lifecycle: evaluation and construction. Effective evaluation and design is critical to maximise value and make the best use of mineral assets. Construction requires significant input of capital and resources, and the Group will often seek a partner for projects.
