Cadence Minerals has received a preliminary environmental licence in respect of its Amapa iron ore project in Brazil, encompassing both mining at Amapa and the re-commissioning of the Azteca processing plant. The next stage in permitting is for the Installation licence, and the process for acquiring this is already well underway. After that comes construction at Azteca, which is already funded, and then production, slated to begin by the end of June. Kiran Morzaria is Cadence's chief executive, and he joins Vox to tell us more.
