Successful exploration depends on understanding the entire mine landscape – the dynamic economic conditions, intense regulatory scrutiny, and growing environmental concerns. Throughout the U.S., Canada, and abroad, we help mineral producers know the risks and benefits through realistic, impartial projections of mineable and marketable reserves, feasibility, mine and quarry sequencing, and associated operational costs.

Our Expertise

Greenfield and Brownfield Exploration

We specialize in managing all aspects of greenfield and brownfield explorations – planning, staffing, financial, and technical.  Our experience includes rare earth and multiple minerals within mines, including industrial minerals, base metals, non-petroleum energy minerals, and precious metals.

Expert Mineral Valuation

We provide project valuation, feasibility studies to enter proposed markets, and mineral appraisals for acquisitions and mergers. Our certified mineral appraiser, Fred Pirkle, Ph.D., P.G., is actively involved with a global effort to set consistent standards for the valuation of mineral assets as a member of the International Mineral Valuation Committee.

Full Environmental and Regulatory Landscape

Our evaluation of special environmental and cultural criteria gives you the comprehensive view needed to assess the mine site for federal and state permit requirements, local and regional impacts, zoning, and land development issues, especially for brownfields.
