Prince Albert Mine Plan of Operations Surface Exploration Drilling <br />4. A truck- mounted drill is used to drill a four to six -inch diameter test hole from the ground <br />surface to the desired depth. <br />5. A water tanker truck, crew service truck, and a utility truck to carry additional drill stem and <br />other support equipment may also be used in support of the drill rig. <br />6. A geophysical log using a truck- mounted probe system may also be used to evaluate the <br />geology and mineralogy of the test hole during and after drilling. <br />7.2 Reclamation of Exploration Disturbances <br />The following general methodology is used to reclaim surface exploration drilling - related <br />disturbances. <br />1. After the test hole is completed and evaluated, the drill cuttings are placed back in the drill <br />hole to a depth five (5) feet below the ground surface (as much as is possible); a three (3) foot <br />cement plug is placed on top of the backfilled drill cuttings to within two feet of the surface; <br />and the top two (2) feet of the hole is backfilled with native material. Any remaining cuttings <br />are spread over the ground surface to a depth of one inch or less. <br />Note: Any drill holes where ground water is encountered will be sealed using bentonite to <br />plug the test hole from a depth 25 feet below the zone of ground water inflow to 25 feet above <br />the inflow zone. <br />2. Any mud pit that was constructed is dewatered by evaporation, or by pumping any <br />accumulated water into a suitable container for reuse, and the pit is graded to bury any <br />remaining accumulated drill cuttings and conform to the surrounding terrain. <br />3. The drill site is graded to conform to the surrounding terrain and ripped or disced for seed bed <br />preparation. <br />4. The drill site access road is graded and disced or ripped where necessary for seed bed <br />preparation. <br />5. The disturbed areas are seeded with the USBLM - specified seed mix for the Club Mesa area <br />(see Table 6 "BLM Approved Seed Mix "), or another suitable seed mix as specified in the <br />relevant Notice conditions or stipulations. <br />6. The reclaimed areas are monitored for proper vegetation growth, with suitable weed control <br />and reseeding provided as necessary. <br />7.3 Surface Exploration Program State Agency Review and Approval <br />Appropriate CDRMS clearances and approval for an expansion of the surface exploration drilling <br />program currently defined in CDRMS Prospect NOI P- 2005 -021 will be obtained on a case -by -case <br />basis whenever the ongoing evaluation of the exploration and mining programs indicates additional <br />exploration work beyond the activity defined in CDRMS Prospect NOI P- 2005 -021 is warranted. <br />Rimrock Exploration and Development Page 27 of 27 <br />
