SURFACE LITHOGEOCHEMISTRY TO ESTIMATE URANIUM MINERALIZATION


Resources in a second northern Arizona uranium exploration JV. Work conducted during and immediately after this relatively short-lived JV (the region was effectively closed to uranium exploration in 2009) provided the data supporting the research and paper provided here. Larry D. Turner is currently conducting greenfields exploration for Au-Te deposits in central Colorado for DIR using a variation of the innovation described by the report.


Irving (Larry) Turner is a retired first-generation mineral explo- ration geologist who graduated from SIU-Carbondale (BS, geology/ physics) and UT-Knoxville (MS, economic geology, 1960). He has two sons and two grandsons professionally involved in mineral exploration and mining, as well as a daughter and granddaughter who graduated


from the Colorado School of Mines in other disciplines. After gradu- ate school, I.L. Turner spent 10 years in underground and surface base metal exploration with St. Joe Lead, and then 4 years manag- ing exploration programs for Vanguard Exploration in Washington State’s Metaline mining district. Following Vanguard, Larry senior became a consultant for several years, managed exploration for NL Industries in Idaho’s Bayhorse fluorspar mining district, and then oined Texasgulf Minerals, Inc.. He retired from maor mining com- pany exploration work after working for a number of years as Leo Miller’s successor as Texasgulf’s VP of Exploration. In 1987, he, his son Larry, and Mohammed Ikramuddin, formed DIR Exploration, Inc., a company that has been active since that year in uranium and precious metals exploration.
