MBA, B. Eng., FAusIMM CP(Met) Principal, Resourceful Paths, Vancouver, Canada
Laurie has 20 years base metals and gold mining operations and consulting experience. He has a Bachelor of Engineering (Minerals Process) from University of Queensland and an MBA (Certificate in Business and Engineering Sustainability) from UC Berkeley.
As Plant Metallurgist at Mount Isa Mines, he worked with a team of metallurgists to configure the AG/SAG/ball mill circuit to operate efficiently at a range of throughputs through optimizing ball charges, cyclone configurations and operating parameters. At Elura and Century mines, he improved operation of fine stirred mill regrind circuits.
At Amec Foster Wheeler, he led the Process Engineering team that provided design, due diligence and operational support services for crushing and grinding, flotation, dewatering, smelting, hydrometallurgy, paste backfill and water treatment in commodities including copper, gold, nickel, zinc and diamonds. He has also led several studies, including the Oyu Tolgoi feasibility study update and Blackwater PEA.
Laurie recently started Resourceful Paths, a sustainability and strategy consultancy, focused on reducing energy and water use in mining, mitigating climate change and maximizing resource recovery.
Laurie is committed to using mineralogy and laboratory ore characterization data to determine optimal flotation feed and regrind sizes that balance concentrate grades and metal recoveries with energy and media costs. He also assesses opportunities for selective mining and pre-concentration to reduce energy currently expended on grinding uneconomic particles.
