Metro Mining Ltd (ASX:MMI) has achieved record shipping in June with a total of 536,454 WMT (wet metric tonnes) loaded onto ocean-going vessels.

Combined with the strong performances in April and May, Metro has exceeded the upper end of its June quarter guidance by 150,688 WMT (14%).

Mining rates remained high but were kept below shipping rates in order to reduce stockpiles to a level easier to manage.

Metro managing director and chief executive officer Simon Finnis said: “We have exceeded expectations throughout the entire June quarter, demonstrating that this level of production is sustainable.

“I must again congratulate all our operational teams, contract partners and all staff who have performed unbelievably well under the difficult circumstances we’re all experiencing as a result of COVID-19. “
