Critical minerals explorer Ring of Fire has appointed a new leadership team, including CEO Kristan Straub and CFO Annie Sismanian.

The new appointments follow the recruitment of Stephen Crozier, VP of sustainability, in August, and long-standing employee Glenn Nolan's transition to the newly created role of VP of indigenous enterprises.

Ryan Weston continues as part of the leadership team in the role of VP for exploration.

Former acting CEO, Stephen Flewelling, will continue at the company in an advisory capacity while former CFO, Greg Rieveley, moves on to pursue other opportunities. 

Parent company Wyloo Metals CEO Luca Giacovazzi said the leadership reshuffle had taken place as momentum built on development in the Ring of Fire.

"Kristan and Annie join us at a time when developing Canada's critical nickel resources has never been more important," he said.

"Kristan's long career in nickel mining, having led global teams and delivered strong health and safety, exploration, sustainability and operational outcomes has prepared him well to lead Ring of Fire Metals in this next phase of the company's growth.

"Annie comes to us with strong experience leading financial performance at a senior level and her contribution will be invaluable as we progress our mine and battery metal production projects.

"Both Kristan and Annie share the broader team's passion and commitment to bringing Eagle's Nest to fruition, and their wealth of experience will stand us in good stead for the path ahead."

Giacovazzi said the creation of the VP indigenous enterprises and VP sustainability roles reflected the priorities of the company at the most senior level.

"Ring of Fire Metals, and Wyloo Metals, are committed to developing mining projects with the highest standards of environmental responsibility and in genuine partnership with First Nation communities – that's why you see these priorities reflected in our senior management structure," he said.

"We are already progressing plans to partner with Indigenous stakeholders on business and employment opportunities, and to develop Eagle's Nest as a net-zero-emissions mine with a small environmental footprint. Along with our promising exploration programme, the leadership team is deeply committed to these priorities."
