Sherritt International Corporation ("Sherritt") (TSX:S), a world leader in the mining and hydrometallurgical refining of nickel and cobalt from lateritic ores, today announced the planned retirement of Chief Operating Officer Steve Wood, effective April 30, 2022. Mr. Wood has worked in the mining industry for more than 40 years, including the past seven as Sherritt's COO.

"Steve has provided invaluable guidance on Sherritt's operations over the years, and I am grateful for his support and the many contributions he has made as a key member of the senior leadership team," said Leon Binedell, President and CEO of Sherritt International. "As a driving force behind our Purpose and Promises, Steve's legacy at Sherritt will be remembered for his commitment to safety, sustainability, operational excellence, and growth. On behalf of everyone at Sherritt, I would like to extend Steve best wishes for his upcoming retirement and look forward to his active role in the pending transition period."

Under Mr. Wood's leadership, the Moa Joint Venture consistently ranked as a low-cost HPAL nickel producer, Sherritt steadily improved its health and safety metrics, becoming peer-leading, and recently launched ambitious sustainability targets to achieve net-zero greenhouse emissions by 2050.

As a result of Mr. Wood's planned retirement, Sherritt made a number of promotions to its leadership team to accelerate the Corporation's multipronged growth strategy, naming:

• Dan Rusnell as Senior Vice President, Metals;
• Elvin Saruk as Head of Growth Projects in addition to his accountabilities as Senior Vice President for Oil & Gas and Power; and
• Greg Honig as responsible for Marketing and the Technologies group in addition to his accountabilities as Chief Commercial Officer.

As disclosed recently, Sherritt is embarking on an expansion strategy to capitalize on the growing demand for high purity nickel driven by the accelerated adoption of electric vehicles. The strategy, which will build on the 26-year successful track record of the Moa Joint Venture, centres on growing annual finished nickel and cobalt production by 15 to 20% from the 34,876 tonnes produced in 2020 and extending the life of mine at Moa beyond 2040 through the conversion of mineral resources into reserves using an economic cut-off grade. This expansion strategy supplements Sherritt's focus on growth through commercializing solutions developed by its Technologies Group.

"Dan, Elvin, and Greg have the right skills, experience, and expertise in their respective roles to drive our growth strategy forward," said Mr. Binedell. "The promotions, which are effective January 1, 2022 and will report to me directly, will help us to better align the organization to our growth initiatives while maintaining strong relationships with our key stakeholders, including our Cuban partners, customers around the world, and the local communities in which we operate."

Dan Rusnell will be responsible for the complete Metals portfolio of operations – from mining at Moa to finished nickel, cobalt and fertilizer production at the refinery in Fort Saskatchewan. Mr. Rusnell joined Sherritt in 2018 as the General Manager of Fort Site Operations where he focused on maturing the safety culture, building a continuous improvement mindset and modernizing business processes. Mr. Rusnell has more than 20 years of engineering and leadership experience, including 14 years at Syncrude Canada Ltd. and 5 years at Nexen Energy ULC (now CNOOC International). Mr. Rusnell is a Professional Engineer registered with APEGA and holds a Bachelor of Science in Engineering (Chemical Engineering) from the University of Saskatchewan.

Elvin Saruk is currently the Senior Vice-President, Oil & Gas and Power where he is responsible for all operational matters and also oversaw the construction of historical projects. Mr. Saruk has more than 30 years of experience in the Oil & Gas and Power businesses with Sherritt. Under his leadership, Sherritt's Oil & Gas and Power businesses have worked closely with various Cuban partners, produced more than 240 million barrels of oil and 43,680 gigawatt hours of power, and contributed more than $3.5 billion of EBITDA over the years. Mr. Saruk was also responsible for leading the construction of all Sherritt's power generating assets in Cuba, which currently have a capacity of 506 megawatts of electricity and were completed over eight phases. He is a professional engineer, with a Bachelor of Engineering (Chemical) from the University of Alberta, and a member of APEGA.

Greg Honig is Sherritt's Chief Commercial Officer, and has diverse international experience spanning private equity, corporate development, and investment banking. Since joining Sherritt in August 2021, Mr. Honig has worked closely with each of Sherritt's Technologies and Marketing groups to advance market development of the Corporation's proprietary solutions and identify opportunities for long-term supply agreements within the electric vehicle supply chain. Previously, he was Principal, Director of Canada for Resource Capital Funds. Mr. Honig's experience also includes business development and strategy, marketing and research at Xstrata Nickel. Mr. Honig holds an Honours Bachelor of Commerce degree from Queen's University, and is a graduate of the University of Toronto's Rotman Directors Education Program.
