The acreage was based on the projected or actual highwall mining <br /> panels as detailed on map series M4 and M10. Only areas under undisturbed, or Phase III bond release were <br /> accounted for as additional affected acreage. Areas of the mine that are active pit or disturbance or reclamation <br /> not yet Phase III bond released are already accounted for as affected and disturbed acres. The additional affected <br /> acreage was calculated at 283.5 acres and will be added to the relevant category on the permit application. <br /> Trappers' response adequately addresses DRMS's question <br /> DRMS 28 February 2023 <br /> DRMS finds Phase III site wide reclamation totals 1369.45 acres as per GIS querrie. <br /> DRMS finds Phase III reclamation in Pits N, B and C comprises a total of 415.66 acres <br /> including the totality of N Pit parcels AB99 and AB94. DRMS then measured the relevant <br /> portions in N Pit parcels AB99 and AB94 and utilized those measurements to arrive at 267.72 <br /> acres. <br /> Through GIS analysis DRMS finds Phase III reclamation comprises approximately 267.72 <br /> acres. And, undisturbed acreage in the B and C Pits to total 35.85 acres,for a total affected <br /> area of 3 03.5 7 acres. <br /> DRMS notes that Trapper estimated the penetration of the highwall miner (PR10), at <br /> approximately 1,200 ft. DRMS is aware that this criterion, has to date, been difficult to <br /> achieve in the N, I and J pits. <br /> 17. Please, as much as possible, ascertain a reasonable average penetration to utilize in <br /> calculating the affected areas undermined around the pit outlines as depicted on the <br /> M4 Map associated with PRI1, as well as for other pits. Please provide that <br /> information in the appropriate revised pages. <br /> Trapper Response to Comments 17: <br /> Despite the total penetration of the highwall mining not reaching the anticipated 1200 feet,the distance was not <br /> reduced for the calculation of the affected acreage. The mining panels are already established on the M4 and <br /> M10 map series and would require modification if a different depth were chosen. That would also potentially <br /> limit the possibility of actually utilizing maximum projected penetration.No change in depth will be presented <br /> at this time. <br /> Trappers' response adequately addresses the above question. <br /> 18. Please see Rule 3.2.2 below, and provide acreages for the various types of disturbance. <br /> In the past Table 3-1-3 has indicated disturbed and reclaimed acres. Should areas <br /> affected by highwall mining now be included in this table as well? <br /> Trapper Response to Comment 18: Trapper would prefer to not modify Table 3.1-3 with affected acreage. This <br /> table has traditionally depicted the same categories of activity as represented on the Annual Reclamation Report <br /> form. In this format,the projected disturbance and reclamation canbe compared directly to the ARR each year. <br /> 8 <br /> Trapper Mine PR I ADQ No 2 <br /> 2023 February <br />
