10:50 AM EDT, 05/12/2025 (MT Newswires) -- Rock Tech Lithium ( RCKTF ) , which gained 3% last Friday, was down near 4% at last look on Monday after announcing a change in its executive leadership team, effective immediately.

The company named Mirco Wojnarowicz as chief executive officer and Christopher Wright as chief financial officer and added that Kerstin Wedemann will continue as chief legal & corporate officer.

Dirk Harbecke, who has served as interim CEO since 2022, will remain Chairman and as Rock Tech's largest shareholder will "also ensure ongoing leadership continuity and strategic oversight".

A statement noted Wojnarowicz, with over 15 years of international leadership experience in the industrial and energy sectors, joined Rock Tech in 2022 as vice president of business development. Since joining Rock Tech, he has led strategic initiatives, including securing offtake and feedstock agreements and establishing Rock Tech's lithium joint-venture with Transamine SA in Switzerland. Before Rock Tech, he held senior divisional leadership roles at Mitsubishi Power Europe.

Wright, with more than 15 years of experience in finance and mining, was an external hire in 2024 with the intention to transition him into the CFO role in 2025. He recently held a role at Liontown Resources where he helped deliver project financing for the Australian based lithium producer. Before that, he provided corporate advice to mining companies, managed natural resource investments for "ultra-high net worth clients", and led assessments of project financing at the Australian Treasury.

A statement noted that the company had also accepted the resignation of Harbecke and Derek Sobel from their interim positions. Sobel was serving as interim CFO. He will continue his work at Rock Tech as the its group financial controller.

"For Rock Tech, these appointments mark an important milestone on the path of our ambitious execution strategy," said Harbecke.
