North American lithium producer LibertyStream has appointed Keirah Burrell interim CFO to replace retiring Morgan Tiernan.

Burrell held the accounting operations VP position at LibertyStream.

She has more than 15 years' experience in public accounting, controllership and finance transformation, having worked at Siegfried Group and PricewaterhouseCoopers.

LibertyStream CEO and president Alex Wylie says Burrell has already been advancing the company's US accounting and reporting capabilities and the board has full confidence in her leadership of the finance function. "Her capabilities provide a strong operational foundation for LibertyStream," he concludes.
