Appendix A - DRMS Form 2 Public <br />Lynx-Royal JV LLC Slick Rock LH-2 2009 NOI <br />No roads will be constructed. The only surface disturbance anticipated will be the excavation of <br />five nominal 10 foot x 10 foot by 3 foot deep containment pits for cuttings and, if needed, air- <br />lifted water from the drill holes. The estimated disturbed area will be about 100 ft square per <br />site, or 0.0115 acres in total. The test pits will be within the larger 30 ft x 65 ft proposed drill <br />pads. For bonding calculations, the entire 1,950 square foot drill pad will be considered <br />"disturbed" although this is highly unlikely. Total surface disturbance then is estimated to be <br />about 0.224 acres. Given the equipment and mud pit constraints, a pad can be a more amorphous <br />shape than indicated above as it is configured to fit around minor topographic and vegetative <br />features. Figure A-1 is a schematic drawing of a proposed pad with equipment locations and <br />cuttings/fluid flow. <br />Drill Pad Schemdtic)l< <br />(approximate olrnensions - for unexcavated pads) <br />65 <br />/ "N""` '?""

Cut material will be temporarily placed <br />in a pile or piles adjacent to the access trail or drill site, and then scattered back over the trail or <br />site during reclamation. See Attachment B for a photo record of the proposed drill sites and <br />access trails. <br />Drill Hole Abandonment <br />A) Plugging Procedure <br />- Dry or Damp Hole - The drill hole will be backfilled as much as possible with <br />cuttings, using the mineralized material first. After backfilling to within about 5 <br />feet from the surface, a spray foam plug will be brought to within about 2 feet of <br />Page 3 of 5
