RE: Mountain Province Diamonds Announces Second Quarter 2020 It is a pretty sad situation . We are selling the diamonds at 44.92 canadian per carat on average that cost "All in cash costs of $50 – $55 per carat recovered, unchanged from previous guidance" to produce. That is a 5 to 10 dollar loss per carat before EBITDA. It is going to be a bad quarter with negative cash flow. Ouch.
