I am an internationally-recognized authority on tailings storage, including alternative tailing disposal. I have been involved with all aspects of heap leach facility design, including dozens of projects globally. I have more than 30 years of experience in independent review, engineering, project management, design, construction, and site investigations for mining-related projects.

I am a recognized leader in geotechnical designs for the mining industry. I am experienced in leading design teams and performing independent reviews of mine waste and heap leach facilities. I am comfortable and experienced with business development, and have the ability to easily make industry contacts. I am a trusted practice leader, having ran one of Knight Piésold’s offices for 12 years. I have many good industry contacts, especially in Nevada.

I am a geotechnical engineer with more than 30 years of experience with engineering, project management, design and construction, analysis, and site investigations of mining-related work. I have participated in all aspects associated with the design of tailings and heap leach facilities and has carried out numerous other geotechnical design efforts, including direct involvement with over 50 geotechnical site investigations. I am considered to be an expert in several fields, including use and interpretation of in situ tests, propensity for static and earthquake-induced liquefaction, material property derivation, laboratory analyses, and slope stability analysis, including the estimation of earthquake-induced slope deformation. I have completed numerous independent reviews of geotechnical designs.

I was on the organizing committee for South Africa’s first major conference on heap leaching, and initiated the Elko Roundtable Discussion seminar series in Nevada, the proceeding of which has been published several times in Mining Engineering Magazine. I have extensive experience in the analysis of slope stability. In addition, I have performed numerous assessments to estimate potential seismic activity for projects located throughout the world. I am well versed in numerous fields associated with soil mechanics, including the basic characteristics of soils, phase relationships, soil compaction, permeability, seepage, the principles of total and effective stresses, shear strength relationships, the critical state concepts of soil mechanics, earth pressure theory, retaining walls, consolidation theory, bearing capacity, slope stability and earthquake hazard. I have received awards from both universities from which I graduated and I also serve on the Minerals Engineering department’s Industrial Advisory Board for the New Mexico Institute of Mining and Technology. I have served on the organizing for the annual Tailings and Mine Waste conference and am a charter members of the ASDSO Tailings Dam Regulatory Committee.
