While the six months ended December 31, 2018, had been challenging for Aim-listed Rainbow Rare Earths from a production perspective, the company is confident that its performance will improve in the coming months. "We have begun to address the teething issues and are now focused on increasing production from new mining areas, targeting near-term positive earnings before interest, taxes, depreciation and amortisation and becoming a key strategic supplier to the market," CEO Martin Eales said in a statement published on Tuesday.
