During the next several months, Mr. Isto will transition his responsibilities to Dr. Martin Raffield, Vice President, Operations, who will assume the leadership of all aspects of Royal Gold’s technical functions upon Mr. Isto’s retirement.

“Mark has been a key member of Royal Gold’s executive management team since he joined in 2015,” commented Bill Heissenbuttel, President and Chief Executive Officer. “Mark’s counsel to me and the management team on technical matters has been invaluable over the past eight years, and his work ethic and attention to detail are truly remarkable. In addition to bringing his technical experience and judgement to every conversation, Mark has grown our internal technical capacity and we have a strong team that is ready to continue applying our high standards to all asset reviews. Martin has spent the last 18 months working alongside Mark learning about our portfolio and our technical due diligence process, and he is well equipped to lead our technical team with the same enthusiasm and commitment as shown by Mark.”
