The holes are NE- 01 -12, NE -17 -12 and NE- <br />18-12 as shown on Map 20 Sheet 1. <br />The exploration holes will require small drill pads and mud pits. Sedimentation control for the drill sites <br />will be provided as shown on Map 25 and explained in Exhibit 19(20) pages 1 -17. The drill holes will be <br />sealed in accordance with permit application pages 2.05 -53a and 54. <br />Drill hole NE -01 -12 is over 100 feet from the Purgatoire river and located above the area that would be <br />considered alluvial valley floor. <br />Amended page 2.05 -5e explains that three exploration holes will be drilled in 2012. Amended page 2.05 - <br />10c explains the sedimentation control plan for the exploration holes. <br />The disturbed area increases 0.5 acres as a result of this revision. The affected area does not increase <br />since the areas have been undermined. <br />Sincerely, <br />J. E.
