Details Of The Scoping Study

The TREC Scoping Study is preliminary in nature and was used as a planning tool to evaluate the various mining and processing options available to Black Range. The Study incorporated information from the Ablation test work, leaching test work, a UBHM study carried out by Kinley Exploration Inc (“Kinley”), current resources prepared by Tetra Tech, TREC’s internal database, and previous feasibility studies. The engineering and design component of the Scoping Study is estimated at an accuracy level of plus or minus 30%, and TREC has recommended that a contingency of 20% be considered for OPEX and CAPEX.

In preparing the Scoping Study TREC used data form the August 2010 resource estimate prepared by Tetra Tech applying a 750ppm cutoff grade, the estimated Indicated and Inferred Resource is 7,78mt containing 19.72Mlb U3O8 at an average grade of 1,270 ppm.
