"I am pleased to present this report and to acknowledge the significant environmental and community work that is undertaken by FCF Minerals. Our commitment to responsible resource management and community upliftment remains at the heart of everything we do. By prioritising local hiring, procurement, and long-term investments in infrastructure, education, training, and livelihood support, we continue to drive inclusive and sustainable growth.
