Commenting on the appointment, Jeremy Martin, Horizonte's CEO, said: "We are pleased to welcome Mike to the Horizonte team. He has extensive experience in developing, operating and optimising nickel operations, his experience across both RKEF and HPAL technologies is well suited to the development of both of Horizonte's projects.

Mike will oversee the development of Araguaia and Vermelho in Brazil and will also be an invaluable asset to the corporate team in London. Horizonte has the capability to build and deliver the Araguaia ferro-nickel project, as well as simultaneously progressing Vermelho.
