Triple listed Clean TeQ has warned of a A$180-million noncash writedown of the carrying value of its Sunrise nickel/cobalt/scandium project, in New South Wales, for the 2020 financial year. The company on Friday told shareholders that a review of the carrying value of the Sunrise project was undertaken based on a conservative best estimate of what the probable project execution plan (PEP) outcomes would be, as well as highly conservative macroeconomic assumptions, including the forecast metal process.
