Tucano Gold's iron ore plantTucano has one of the only green iron ore plants in the world that will process gold tailings/ waste that's rich in iron ore. The region they're in is traditionally a big iron ore producing area and their tailings are said to contain 20-40% Fe.
This could be a great way to bring down AISC on gold production, plus a way to lower costs on the tailings dam capacity by processing the roughly 35 million tonnes of tailings currently sitting there. They're also talking about a possible spin out.
