Mr. Yancey is responsible for all of the Company’s exploration projects in the Western US and Paraguay.  With the commencement of production, and with development occupying a good portion of the Company's efforts, he will ensure that the Company's exploration projects remain a priority and advance at a rapid pace.

Mr. Yancey received his BSc in Geology from  Trinity   University San Antonio Texas  in 1975, and his MSc in Geology from the South Dakota School of Mines and Technology in 1978. Mr. Yancey began his professional career with the USGS, Uranium and Thorium Resources Branch, in 1978.  He continued working in uranium development through 1989 while employed in exploration and in-situ mining production for Wyoming Minerals Corporation, Caithness Mining Corporation, Mobil Oil, and Moore Energy. From 1989 to 2005, Mr. Yancey concentrated on reclamation investigations at various uranium mill tailings sites throughout the southwest  United States  for mining companies, government agencies and First Nations. He has served as a member of the UEC team since January 2006, and is currently a Registered Professional Geologist in Wyoming and Texas.

Andrew Kurrus, BSc, MSc Vice President of Resource Development 

Mr. Kurrus is a professional geologist specializing in the exploration and production of economic uranium deposits in South Texas. Mr. Kurrus has an impressive 36-year career in South Texas beginning with Intercontinental Energy Corp in 1978, followed by other notable uranium mining companies: Pioneer Nuclear, Tenneco, Malapai, Total, and Cogema.

While at Total (now Areva), and most recently at Mesteña Uranium LLC (owner of the Alta Mesa ISR uranium mine), he discovered previously unknown ore deposits and orebody extensions at existing ISR operations that contributed significantly to the economics of those projects. Mr. Kurrus is registered as a Professional Geologist; he received his BSc and MSc in Geology from the University of Arkansas.

Harry Anthony, BSc, MSc Engineering Mechanics, PEng Senior Advisor 

Mr. Anthony is an internationally recognized expert in the uranium industry. Mr. Anthony has been a professional engineer for 44 years, the latter 38 of which, he has been at the forefront of multiple aspects of the uranium industry.

Mr. Anthony is particularly noted as being a pioneer of the emerging extraction technology for the uranium mining sector known as In Situ Recovery, or ISR. ISR is a significantly less costly and less environmentally obtrusive technique for mining uranium than any other method currently in use. He has been involved with every notable ISR uranium mine in the US and abroad, at all levels of development, including feasibility, design, operations, and management.

Mr. Anthony was a senior officer and director of Uranium Resources Inc. ("URI"), a public company and a significant uranium producer in the US. During his 20-year tenure at URI he was responsible for all technical aspects of mine development. He has also provided technical services and mine plans for Union Carbide, Urangesellschaft, Kennecott, Rio Algom, Heathgate Resources, and others.

Mr. Anthony is a sought-after speaker on uranium and related issues, having written and presented numerous reference papers on behalf of leading internationally recognized bodies including the IAEA. He is a current and past member of several professional uranium-related societies. Mr. Anthony has a BSc and MSc in Engineering Mechanics from Pennsylvania State University.

Leonard Garcia, RPL Land Manager
