Since then <br />BLM has completed their Environmental Assessment and are working on the engineering and reserve estimate <br />for the modified lease. BLM has hired a new Mine Engineer (Foster Beckett) in the Craig, Colorado field office. <br />BLM representatives Foster Beckett and Rob Enrst have both been out to Colowyo to do a field tour of the <br />proposed lease area and reviewed our geological and mineable reserves. However, since drill hole data was <br />lacking for the specific area in question, additional drill hole information was requested. Colowyo has <br />completed additional drilling within the lease area that has enhanced our modeling of the area. Colowyo then <br />reviewed this new model with BLM representative Foster Beckett, to determine if it will meet their needs. BLM <br />has since told us that they are satisfied with the model and should be able to calculate the mineable and <br />geological reserves. <br />Due to the new modeling data, Colowyo has re-assessed the area for highwall mining potential and has <br />increased the overall tonnage and area to be modified. This will be sent to CDMG in the near future, early <br />September for their concurrent review. <br />In order to ensure there is enough time for both Colowyo and CDMG to review this permit submittal, Colowyo <br />requests a 90 day extension as per the Colorado Mining Rules and Regulations regarding abatement. If you <br />have any questions regarding this matter please call Bob Young. Thank you for your time and attention to this <br />matter. <br />Sincerely, <br />C.
