Sphinx helps clients achieve their business goals by helping publicly traded mining companies provide compliant and meaningful disclosure regarding their mining properties. Sphinx also provides decision-making support through the application of modeling, simulation, and optimization to mining systems. We will work with your staff or independently to provide technical support and help you make better business decisions so you will have more sustainable and profitable mines. We also provide mine planning services for improving efficiency or for feasibility studies.

Dr. Kwame Awuah-Offei is the Union Pacific/Rock Mountain Energy professor of mining engineering at Missouri University of Science & Technology and the principal consultant at Sphinx Mining Systems. From Jan 2015 to Aug 2016, he served as the mining engineering academic fellow at the US Securities & Exchange Commission (SEC). In that role, he was the technical lead in the SEC’s effort to review and revise its mining property disclosure rules. His work led to the Commission proposing new rules for mining property disclosures. He also contributed to the final rules for disclosure of payments by resource extraction (oil, gas and mineral) companies. Thus, he has experience in disclosure issues for mining registrants relating to property and other disclosures that are specific to mining.

He holds a BS (Hons) from the Kwame Nkrumah University of Science & Technology, Ghana. He has over 15 years of research and teaching experience. Dr. Awuah-Offei has extensive experience in modeling, simulation, and optimization of discrete, dynamic, and discrete-dynamic systems in mining. His current research interests include modeling and optimization of mining systems, design and management of sustainable mining systems, mining equipment performance evaluation, and earthmoving equipment-formation interactions.

Dr. Awuah-Offei is the author of a book and over 70 peer-reviewed journal and conference papers (see publications). He has also served as editor of a volume on Energy Efficiency in the Minerals Industry. He is also the author of three technical reports for US state and federal agencies. He is a member of the Editorial Board of the International Journal of Mining & Mineral Engineering.

He has worked in surface gold mining and aggregates operations. He worked in the corporate engineering group of Granite Construction, Inc. (NYSE: GVA). His work with Granite included evaluating and managing (in conjunction with site engineers) capital expenditure projects; working with site engineers to optimize and improve mine and plant processes; long-range mine planning; and equipment management. He has taught graduate and undergraduate mining engineering courses in addition to his research responsibilities.
