Appendix A - DRMS Form 2 Non Confidential <br />Cotter Corporation - SR-13A 2009 N01 <br />horizons of sandstones assigned to the Salt Wash Member of the Morrison Formation in the <br />project area. <br />Drilling will be done by a truck-mounted rotary rig capable of drilling from 1,000 feet to 1,500 <br />feet or so, such as a Gardner-Denver 1500 or equivalent. Hole diameter will be in the 5"to <br />6"range, and cuttings will be removed by airlift. Although considered unlikely, a nominal 1,000 <br />gal to 2000 gal water truck will be available if water is needed to make an air/foam mixture. If <br />an air foam mixture is needed, then the foaming agent will be an environmentally benign, non- <br />hazardous and non-toxic product such as Quik-Foamrm or equivalent. <br />Cuttings will be directed into the containment pits at each site and mineralized cuttings will be <br />segregated within the pit. <br />Probing will be accomplished with a truck-mounted probe unit possessing gamma and electric <br />logging tools. No tool with a radioactive source will be used. <br />Surface Disturbance <br />No roads will be constructed. The only surface disturbance anticipated will be the excavation of <br />two 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 0.002 acres in total. <br />Drill Hole Abandonment <br />A) Plugging Procedure - The drill hole will be backfilled as much as possible with <br />cuttings, using the mineralized material first. After backfilling to within about 5 feet <br />from the surface, a spray foam plug will be brought to within about 2 feet of the <br />surface. The remainder of the hole to the surface will be filled with soil and cuttings. <br />The hole will be permanently marked with a 2"x2" wooden stake on which a tag <br />bearing the hole designation number is affixed. <br />B) Surface Restoration - To the extent possible, remaining drill cuttings will be placed <br />into the containment pit for burial. The disturbed ground will be graded and an <br />approved seed mixture will be broadcast immediately following reclamation <br />C) Estimated Cost of Surface Restoration - Estimated cost of the surface restoration is <br />approximately $200.00 <br />Compliance with Statues and Regulations <br />For exploration, Cotter will use the services of contractors. All Cotter contracts with service <br />companies will contain specific sections requiring compliance with all applicable Federal, State <br />and local statues and regulations. <br />Page 2 of 3
