Global Resource Engineering (GRE) is a multifaceted engineering firm specializing in the mining industry. Our focus is to add value to your project and company by understanding your needs, employing innovative ideas, and applying sound engineering practices while maintaining an economically-driven approach.


While other companies might have a “we are the experts” attitude, which discounts or often ignore the experience of the clients on their own sites, we will work closely with you and your team to provide a solution that fully meets your needs and expectations. Our team recognizes mining is a complex and multi-faceted business, where a solution to each challenge may have unexpected effects elsewhere in the project. At GRE, we work to consider the project as a whole, no matter what portion of the project our focus may be on. Our clients tell us that we provide personalized service, consistent high-quality work, and better communication than larger firms.


Our mining consulting services includes: geology mapping and modeling; hydrology; resource and reserve estimation; open pit and underground mine design, mine planning, and optimization; financial analysis and constraint modeling; metallurgical design and process flow sheet development; process audits; heap leach and tailings design; mine waste facility design; geochemical risk mitigation; geotechnical; ARD auditing, mitigation, and closure planning; field investigations; site water management; groundwater modeling and overall project water balance; project due diligence; and land management.


GRE was pleased to be awarded the "Fastest Growing Business" in Denver (2013). GRE experts have presented papers in PeruMin, for the International Council on Acid Generation, for the International Mine Water Association, ALTA Copper Conference, Mining Sustainability and Environmental Management Conference, International Biohydrometallurgy Symposium, Minerals Engineering, Hydrometallurgical Journal, and many others. 



Over the last 5 years, GRE has been involved in projects ranging from a feasibility study where GRE performed geology, resource, reserve, project optimization, metallurgical review and geometallurgy, site hydrology, tailings, waste rock facility design, closure, and ESIA submittal for a 22,500 tonne per day polymetallic project in South America, to ARD kinetic testing, mitigation modeling and pilot testing for a 20,000 tonne per day operating porphyry copper mine in eastern Europe.

GRE personnel have experience working in a wide variety of countries including: USA, Canada, Mexico, Venezuela, Peru, Bolivia, Brazil, Chile, Gyana, Argentina, Costa Rica, Columbia, Honduras, Puerto Rico, Ireland, Greece, Armenia, Turkey, Tajikistan, Kazakhstan, Papua New Guinea, Australia, New Zealand, Ghana, Mali, Burkina Faso, Namibia, South Africa, Zimbabwe, Botswana, Tanzania, India, Russia, and China.
