The exploration geologist known for discovering 17 major mineral deposits and co-authoring the Lowell Guilbert Model died in Arizona this week aged 92.
J. David Lowell’s discoveries included La Escondida in Chile, which was developed into the world’s largest copper mine, and the nearby Zaldivar-Escondida Norte orebody.
His 50-plus published articles included the paper co-authored with John Guilbert in 1970 defining the porphyry copper model – a deposit type thought to account for 60 per cent of the world’s copper.
He has recently been working as a consultant and strategic partner of Solaris Resources, which this week issued an announcement celebrating his achievements.
“David was the ‘World’s Best Mine Finder,’ discovering 17 major minerals deposits over a 50-year career,” Solaris president and chief executive officer Daniel Earle said.
“Our flagship project, Warintza, was a discovery he made while exploring in southeast Ecuador in the early 2000s, and our pipeline of grassroots exploration projects were his targets for future discoveries.”
Lowell’s achievements were detailed in his autobiography, ‘Intrepid Explorer: The Autobiography of the World’s Best Mine Finder‘.
