Last month, Mountain Province said it would withdraw its forecast for 2020 until it had gauged the effect of COVID-19 on its operations. The miner confirmed Monday that it had suspended most long-term and non-core projects, as well as the company's formal sales in Antwerp. It added that its mine continued to operate, albeit on four-week rather than two-week crew rotations.The miner noted that it was currently "working through various planning scenarios" to assess the full impact on production and would "communicate this to the market when [it had] more clarity and certainty on what the future may look like." It has meanwhile drawn $25 million from its revolving credit facility to alleviate the blow.Shares in Mountain Province rose 10% Monday.Image: The Gahcho Ku?(C) mine. (Mountain Province)
