NI 43-101 Preliminary Assessment - Centennial Uranium Project, Weld County, Colorado - August 13, 2010 (Released August 20, 2010)
Posted August 25, 2010, Updated August 26, 2010
This 162-page, 8.5 MB file has been split into 35 smaller files to facilitate review and analysis. The report contains the most detailed and current maps and descriptions of Powertech's proposed Centennial project, including the novel and unproven mining technique of "aquifer enhancement". However, it is missing several important facts that impact the economics and risks of the project.

News release - "POWERTECH RECEIVES POSITIVE RESULTS FROM INDEPENDENT PRELIMINARY ECONOMIC ASSESSMENT ON CENTENNIAL PROJECT" - Powertech Uranium Corp. - August 20, 2010 (PDF 162 KB, 3 pages) From Powertech CEO Dick Clement: "the project is one of the best undeveloped uranium deposits in the U.S." If the Centennial project is one of the best, why do six out of nine proposed mine units require aquifer enhancement to raise the groundwater level? Why can't Powertech cite even one ISL uranium mine that has successfully used this mining technique?
