Appendices — DRMS Form 2 Public <br />Lynx -Royal JV LLC Wray Mesa NOI <br />Drilling will be done by a truck- mounted rotary rig capable of drilling from approximately 1,000 feet to <br />1,500 feet, such as a Gardner - Denver 1500 or equivalent. Drill hole diameter will be in the 5 "to 6 "range, <br />and cuttings will be removed from the hole by airlift. Although considered unlikely, a nominal 1,000 gal <br />to 2000 gal water truck will be available if water is needed to make an air /foam mixture. If an air foam <br />mixture is needed, then the foaming agent will be an environmentally benign, nonhazardous and non- <br />toxic product such as Quik- FoamTM 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 or portable unit possessing gamma and <br />electric logging tools. No tool with a radioactive source will be used. Water from the water truck may be <br />added to the hole to improve the down -hole electrical characteristics, however this is unlikely. <br />Surface Disturbance <br />No roads will be constructed. The anticipated surface disturbance will be the possible excavation of 24, <br />nominal, 10 foot x 10 foot by 3 foot deep containment pits for cuttings and, if needed, airlifted water <br />from the drill holes. The estimated disturbed area for the pit and stockpiled material will be about 13ft X <br />18ft or 234ft or 0.005 acres per site. 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 "disturbed" <br />although this is highly unlikely. Total surface disturbance therefore is estimated to be about 1.07 acres. <br />Given the equipment and mud pit constraints, a pad can be a more amorphous shape than indicated <br />above as it is configured to fit around minor topographic and vegetative features. Figure A -1 is a <br />schematic drawing of a proposed pad with equipment locations and cuttings /fluid flow. <br />= a utp uzr; ,.> <br />Drill Pcci SLI1.9irdf.it >� <br />nr,innc fn: <br />Spod <br />11...

In the event that large amounts of water <br />are encountered during drilling, the pits will be designed and maintained so that only decanted water is <br />allowed to absorb into surrounding areas that are not ephemeral drainages. <br />Appendices Page 3 of 8 <br />
