<br /> <br /> <br />' RECLAMATION BOND ESTIMATES <br />The following bond calculations are associated with the previously described forty seven hole exploration program <br />and 10 miles of seismic surveys and are based on worst case scenarios . This information is provided to assist in <br />determining required Performance Bond. <br />DriO Hole Abandonment <br />' Assumptions: <br />47 holes at an average depth of 1,327 feet per hole, with an additional 10 holes twinned. <br />' Hole diameter 6.25". <br />Cement Requirements based on entire hole fully grouted. <br />' Hourly Cost <br />Drill Rig, with water truck, flat bed, pickup truck. Hourly rate of $200. <br />estimated maximum of 8 hours per hole. <br />47 holes + 10 twins' $1,600/hole <br />Total Hourly $91,200 <br />Material Cost <br />Based on cement in entire drill hole <br />(most expensive alternative) <br />' Cement slurry mixture, 1.59 gal./lineaz ft. <br />(6.25" diameter drill hole). <br />' ] 5 sacks cement to create 500 gallons of slurry, enough for 314 lineaz feet of drill hole. <br />Total footage for project estimated at 75,639 feet, (includes 10 twin holes). will require a maximum <br />of 3,5 ] 1 sacks of cement. <br />~ , Cement cost $8.50 per sack • 3,613 sacks <br />t Total Material Cost $30,713 <br /> <br />1 <br />i~ <br />
