Speaker
Mark Bowater
Founder & Director
Insignia Mining
Keynote | Built to fail: Rethinking mine planning from the ground up
10:15 AM - 10:45 AMBiography
Mark Bowater is a mining engineer with more than 35 years of experience in the Australian and global open pit mining industry, spanning coal and metalliferous operations. He has held senior operational and technical roles, founded and led a successful mining consultancy, and worked across more than 50 mining operations.
In recent years, Mark has shifted his focus toward working “on the industry” rather than in it—challenging conventional thinking and advancing how mine planning is understood and practiced.
He is the author of Crimes Against Mine Planning and a recognised thought leader on the evolution of mine planning. Through his writing, speaking, and training, he advocates for a fundamental shift away from deterministic planning toward decision-centric approaches that better reflect the realities of uncertainty and variability.
Mark is driven by a clear purpose: to leave mine planning in a better place than he found it. He is passionate about helping the industry rethink how mine planning is structured, how decisions are made, and how capability is developed—so that mine planning can better support operational performance and decision-making.
