Argo Advisors International is a fully incorporated and insured entity based in Massachusetts, USA that specializes in consulting and engineering projects in the extractive metallurgical and precious metals industries. Mike Mooiman is the President of the Argo organization and, as needed, he draws upon the expertise of consultants, engineers and specialists in extractive metallurgy as well as precious metals recovery and refining to assemble highly qualified and experienced teams that can quickly and effectively resolve challenging and pressing issues.

With its depth and variety of expertise, Argo is well positioned to advise its clients. The Argo team works with clients to understand their needs and constraints and collaborates to find solutions that are practical, prudent and cost effective. Argo Advisors International is selective in its choice of clients and prides itself on delivering honest and straightforward answers.

With our specific focus on the precious metals industry, we are different from large engineering consulting groups. You will not be paying us to learn your industry and business. We are industry veterans, many of us with over 30 years of experience in precious metals with an extensive list of contacts.

Specific engagements have included:

Extractive Metallurgy and Precious Metals;

 Independent Reviews of Operations

 Strategic Planning Reviews and Studies

 Flowsheet Development for Precious Metals Operations

 Technical and Financial Assessments of New and Existing Precious Metals Projects

 Preliminary Costing of Precious Metals Projects

Energy Industry;

 Energy analysis of cogeneration of hot water and heat for a large apartment building in Toronto, Canada

 Development of Renewable Energy Grant Funding Criteria for a Public Utilities  Commission

 Review of Carbon Footprint Impacts of Large Solar Project

Mike has Master’s degrees in Chemistry and Business and a PhD in Metallurgical Engineering (University of Utah) and he has spent most of his career in the extractive metallurgy and precious metal business starting as a gold miner in South Africa. He has served as VP Production and General Manager for Metalor Technologies USA, one of the largest precious metal companies and refiners in the US, and has published over 40 papers.

He is also the holder of two US Patents for precious metal recovery. He is the President of Argo Advisors International, a consultancy and engineering company that specializes in the precious metals and extractive metallurgical industries.

Mike has worked and consulted for major metallurgical research organizations and metals operations in the USA, South Africa, Europe, and Canada. When he is not consulting, he is a Professor in the MBA program at Franklin Pierce University, New Hampshire.

He is a member of the Mineral, Metals and Material Society and Co-President of the New England Chapter of the International Precious Metals Institute. During the summer of 2009, he was a Visiting Scholar at the Federal Reserve Bank in Boston. In 2015 Mike was awarded a Fulbright Scholarship by the US Government for energy studies in Botswana.

Mike is a Professor in the MBA Program at Franklin Pierce University where he developed and administers the MBA in Energy and Sustainability Studies

Mike is a member of the Advisory Board for EMEW, a company involved in the design of equipment and processes for the electrolytic recovery of metals from dilute solutions
