Lost Creek


On August 2, 2013, the Company began production activities at its Lost Creek Project.  Innovative design and development have focused on employee and environmental safety, water management practices, and advanced instrumentation monitoring and data capture.  As of October 2013, all production circuits of the plant were commissioned and uranium yellowcake had been processed, dried and packaged.  First sales of Lost Creek yellowcake were made in December 2013.

In all six quarters since production operations began, Lost Creek has made product sales into contractual commitments. During the first quarter 2015, 192,280 pounds of U3O8 were captured within the Lost Creek plant. 177,057 of those pounds were packaged in drums and 171,505 pounds of drummed inventory were shipped to a conversion facility where 146,000 pounds were sold to utility customers. Operational results quarter to quarter are as follows:

The Lost Creek Project is part of the larger Lost Creek Property located in the Great Divide Basin, Wyoming which comprises six projects covering a total of approximately 42,000 acres (16,997 hectares): Lost Creek permit area (“Lost Creek Project”), EN, LC South, LC North, LC East and LC West.  The uranium deposit at the Lost Creek Project is referred to as the Main Mineral Trend (“MMT”).  The Company’s East Mineral Trend (the “EMT”) is a second mineral trend of significance.  It was identified by historic drilling on the lands forming LC East.  Although geologically similar, it appears to be a separate and independent trend from the MMT.  

Lost Creek currently employs approximately 56 full time employees.  The Company holds long-term sales contracts with several U.S. based nuclear utility companies, spanning the time frame 2013-2020, and anticipates making additional sales into spot market sales agreements.  The uranium produced at the Lost Creek Project will ultimately become the fuel that provides clean energy for the nation’s power grid.
