Glenn Kondo has joined Orca after being announced as CFO at Strongbow Exploration in March but not making it to the June 1 start date.
Before that, he served in the same role at fellow Lukas Lundin-linked company Lucara Diamond Corp.
Orca CEO Rick Clark said Kondo's experience in the team that brought the Karowe mine to production would be helpful as his company developed the Block 14 gold project.
Outgoing CFO Yip would "continue his career with the Lundin Group of companies in Vancouver", Clark said.
Kondo will be based in the UK.
