Lucapa Diamond managing director and chief executive Stephen Wetherall is set to resign from his position at the end of July.
He will be replaced on an interim basis by Nick Selby, who had been an executive director of operations since September 2017.
"I have thrived on the challenges put to me by the board and shareholders, and together with our valued teams worked hard to build on our vision," said Wetherall.
"We have together navigated the company successfully through a difficult pandemic, repaid all the project interest-bearing debt, successfully delivered and expanded two mining operations now generating solid margins, positioned the company for growth with future production from Merlin and our kimberlite exploration programme at Lulo is at an advanced and exciting phase."
Lucapa said that it plans to retain Wetherall as an independent consultant on arm's-length commercial terms to continue to advance the company's diamond marketing and downstream operations.
He joined Lucapa in 2014 and helped the company grow and transform from a pure exploration company to an integrated multi-asset diamond group with niche high-value assets spanning exploration, mine development, and production, according to company chairperson Miles Kennedy.
