The Canadian Mining Hall of Fame (CMHF) announced four new inductees on Oct. 15, who are being honoured for their significant contributions to both the Canadian and global mining industry. The new members are Sean Boyd, Frank Giustra, Donald Roderick MacLean, and Patricia Ann Sheahan. 

“The 2025 inductees are exemplary pillars within the mineral exploration and mining community, each of whom has left a lasting legacy in advancing a more sustainable, responsible and prosperous industry,” said Deborah McCombe, chair of the CMHF, in an Oct. 15 press release. “Mining is an essential economic driver of prosperity, and our 2025 inductees have played a major role during their careers in ensuring Canada is a global mining leader. They are role models for future generations to follow, and we are proud to recognize their achievements and share their stories to inspire others who will follow in their footsteps.” 

During his tenure at Agnico Eagle, Sean Boyd transformed the company from a single-mine operation into one of Canada’s largest public corporations and a leading global mining company. He started with the company as chief financial officer (CFO) in 1990, and later served as chief executive officer (CEO) from 1998 to 2022. After that, he became executive chair and chair of the board. Successes credited to Boyd include growing the company’s market capitalization to more than $55 billion from $400 million and expanding its operations into Europe, South America and Australia. Beyond corporate success, Boyd has made significant contributions to the communities that Agnico Eagle operates in, including spearheading the company’s $1 million donation to the Historic Cobalt Legacy Fund in 2015 and setting up the Dr. Leanne Baker Scholarship and Development Program in 2022 to support women in leadership roles in the mining industry. Boyd’s success as a leader earned him a spot on Harvard Business Review’s list of Best-Performing CEOs in the World. 

Frank Giustra is an entrepreneur, financier and philanthropist who founded Silver Wheaton, which is now Wheaton Precious Metals, and played a crucial role in establishing and growing Wheaton River Minerals, leading its merger with Goldcorp. In 2001, Giustra was appointed chairman of Endeavour Financial, and later founded Endeavour Mining. In 2005, Endeavour created UrAsia Energy, which was acquired by SXR Uranium in 2007 for $3.4 billion. From 2016 to 2019, Giustra served as chairman of Leagold Mining, leading its successful merger with Equinox Gold. He is also a major backer of Nations Royalty, Canada’s largest majority Indigenous-owned public company. Giustra's philanthropic work includes founding The Giustra Foundation in 1997 to support initiatives for women, children, education and refugee resettlement, as well as co-launching Acceso in 2007, a non-profit that empowers rural smallholder farmers in several countries through sustainable market participation. 

For over 60 years, Donald Roderick MacLean dedicated his career to revolutionizing underground mining safety worldwide. MacLean grew up in small mining towns in Quebec, where his father, Don MacLean, managed local mines, providing him with early hands-on experience in underground mining. Following his time as shift boss for International Nickel at the Levack site in Sudbury, he established MacLean Engineering in 1973, which now employs over 1,000 people in six countries. A year prior to MacLean's passing in 2024, MacLean Engineering celebrated its 50th anniversary. MacLean's contributions to the industry led to his induction into the International Mining Technology Hall of Fame in 2014, the Sudbury Area Mining Supply and Service Association Hall of Fame in 2016 and won him the CIM Mining Safety Leadership Medal in 2023.  

Patricia Ann Sheahan is a geologist and industry leader who dedicated nearly 60 years to publishing her impactful newsletters through Sheahan Literature Service, a global technical information service for exploration companies focused on diamonds and base and precious metals. Sheahan first worked at Selco Exploration Corporation before establishing Konsult International Inc., her own consulting firm, in 1972. Sheahan continued working on the newsletter she started in 1963 until she retired in 2022, ultimately serving over 400 clients across the globe. Sheahan's impact also reached her volunteer work with various professional associations, including the Engineers’ Club of Ontario and the Geological Association of Canada. Her numerous accolades include the 2016 PDAC Distinguished Service Award and the 2012 Queen Elizabeth II Diamond Jubilee Medal. 

These four new members will be honoured during the CMHF’s annual dinner and induction ceremony, which will take place on Jan. 9, 2025, at the Metro Toronto Convention Centre.
