The AIM-traded firm said Tyrrell would remain available until 30 June to assist with the transition.

A formal process to appoint a permanent chief operating officer was confirmed to be underway.

Richter has served as Greatland’s group mining engineer since 2021 and has more than 25 years’ experience, predominantly in open pit and underground gold mining.

The company said he had been a key member of the senior leadership team, involved in operational and mine planning decisions, and had a detailed understanding of its assets.

“Simon has been an important part of Greatland's management team and we appreciate his positive contribution towards the company's safety and operational outcomes,” said managing director Shaun Day.

“I thank Simon for his efforts and commitment to Greatland and wish him well in his future endeavours.”

At 0937 GMT, shares in Greatland Resources were up 0.14% at 640.9p.
