The cost is based upon the volume <br />and the average distance to be moved. The distance was determined by centroid method. <br />The sheet was corrected to read "Golden Eagle Mine". The material was kept as 2~% <br />rock 75% earth due to the general weight and swell of "earth" material in Colorado. I <br />could accept the azgument in an azea that is composed of sandy soils, however generally <br />there will be some rock component in Colorado soils so the tendency is to use the <br />rock/soil swell factor. <br />Task 15 & 16: See explanation of swell factor in explanation of Task 7. <br />Task 13: Corrected as per your inputs. <br />Task 11: Seeding and subsoiling of l2 acres removed from Task 11, and calculated as <br />sepazate task 17. subsoiling of the remaining 49.85 acres was removed from Task 11. <br />Sealing of monitoring wells: My confusion on the inclusion of water monitoring. That <br />has been removed. Thank you for the detail on the alluvial wells and the bedrock wells. <br />Costs for sealing the wells has been included as Tasks 18 and 19. <br />C:\j hb\team\C 8 l 013 costest.doc <br />i <br />
