Services
Project Management
We provide comprehensive Engineering, Procurement, and Construction Management services for mining projects. Our team has successfully delivered major projects like the $140 million Pinos Altos mine in Mexico, including infrastructure development, plant construction, and operational start-up. We manage all project phases from feasibility studies to commissioning, ensuring technical excellence and budget adherence.
Engineering Services
Our engineering division specializes in metallurgical process design and plant optimization. We offer feasibility studies, LiDAR scanning for plant retrofits, and heap leach system design. With decades of experience in precious metals processing, we develop customized solutions for new facilities, expansions, and operational improvements across diverse global environments.
Laboratory Testing
Our 35-member laboratory team conducts comprehensive metallurgical testing on over 100 projects annually. We specialize in cyanide and acid leaching processes, gravity concentration, and electrowinning. Our facility features North America's premier HPGR pilot unit for comminution testing, supporting flowsheet development for heap leach and milling operations worldwide.
Heap Leach Design
As pioneers in heap leaching since 1972, we design efficient leaching systems with optimized solution application methodologies. Our expertise includes large-scale operations like the 17,000 tonne/day La India project. We develop complete heap leach pads, solution recovery systems, and environmental controls for sustainable mineral extraction operations.
HPGR Testing
Our pilot-scale HPGR unit processes 6-8 tonnes per hour for flowsheet development. This advanced facility enables accurate scaling for full production units in both heap leach and milling applications. We analyze operational parameters like pressure settings and gap control to optimize energy efficiency and particle size distribution for various ore types.
