Tolu Minerals’ founding managing director and chief executive officer Iain Macpherson will exit the business from the end of his current contract on November 9.

The company board praised Macpherson for leading the company through its most recent phase of growth.

“The board of Tolu Minerals is appreciative of (Macpherson’s) efforts in preparing for restart of the Tolukuma gold mine and assisting in putting Tolu on the global map,” the company said, noting that the company’s next phase would be even more pivotal.

“Tolu is at a critical time in its development and preparing for a substantial increase in exploration and resource definition leading into production.”

Tolu Minerals executive chief geologist Chris Mueller has been tapped to lead the company into this period.

Mueller joined the company in January, having led the exploration function at K92 Mining for eight years prior to that. Overall, he has more than 25 years of global mining and exploration experience across underground, open pit and surface operations. That includes 20 years deeply committed to PNG’s mining sector, where he has helped shape several landmark projects.

In a previous position at K92 Mining, Mueller won the Thayer Lindsley Award for the discovery of Kora North and contributed to the definition of more than 22 million gold equivalent ounces across a range of projects.

“Dr Mueller brings a proven track record in mine restarts, resource development and world-class discoveries,” the company said.
