Appendix A - DRMS Form 2 Public <br />GeoLynx LLC Crampton Project 2010 N01 <br />No more than two drill holes will be left open at any one time. <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 or concrete plug will be brought to within <br />about 2 feet of the surface. The remainder of the hole to the surface will be filled <br />with soil and cuttings. <br />- Wet Hole - Non-flowing Aquifer. While not expected to occur, the hole will be <br />backfilled with a thick bentonitic mud with a > 50 second viscosity to a point 50 <br />feet above the static water level. The mud will be pumped to the bottom of the <br />hole through the drill pipe and the pipe will be periodically withdrawn as the mud <br />level rises in the hole. If closure occurs when the drill rig is not available, <br />3/8"bentonite chips will be added to the hole in a manner as to avoid bridging <br />until the bentonite chip backfill column is at least 50 feet above the static water <br />level. The remainder of the hole will be backfilled as per a dry or damp hole. <br />- Wet Hole - Flowing Aquifer. While considered highly unlikely, if a flowing <br />aquifer is penetrated, then drilling will pause and the permitting agencies will be <br />consulted for recommended abandonment methods. <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 (See Attachment C) will be broadcast immediately following <br />reclamation <br />Estimated Timetable and Reclamation Costs <br />A) Timetable: <br />a. Drill holes will be backfilled/plugged within 48 hours of completion of <br />drilling. <br />b. Site reclamation: <br />i. If dry spring/summer, the site will be reclaimed as described above <br />within 1 week from when the rig is removed. The ground will be <br />raked and the seed will be broadcast at that time per Exhibit C and, if <br />need be, again in the late fall. <br />ii. If winter and the ground is frozen and/or snow covered, the site will be <br />cleaned up and any pits backfilled, but the final reclamation will occur <br />as soon as the site is accessible with minimal impact in the spring or <br />summer. <br />B) Estimated Cost of Drill Hole Abandonment. - The estimated cost of backfilling the <br />proposed drill holes is $1.25/ft. <br />C) Estimated Cost of Surface Restoration - Estimated cost of the surface restoration is <br />approximately $400.00 per hole. <br />Page 4 of 6
