ASX-listed aspiring manganese producer, Element 25, has struck an offtake agreement to sell half the manganese ore produced under a proposed stage two expansion of its Butcherbird project development in WA’s southern Pilbara region. The Perth-based company says its new offtake partner, private equity firm and commodity trader Semeru Energy, will buy between 175,000 tonnes and 200,000 tonnes per annum of Butcherbird manganese ore.
