EXHIBIT G - WATER INFORMATION <br /> Operations at the Stiles Mining Resource will affect surface water associated with the South Platte River <br /> located to the north of the mine (Exhibit C)and groundwater associated with the South Platte River <br /> alluvial aquifer(i.e., uppermost aquifer).The only structures on adjacent lands with the potential to be <br /> affected by the mining operation are five(5)wells that were identified within 600 feet of the permit <br /> boundary using on the Colorado Division of Water Resources(DWR)Colorado's Decision Support System <br /> (CDSS)Well Permit Viewer.The location of the wells is shown on Exhibit C.The following table <br /> summarizes construction details for each of the wells. t <br /> r•�' fir,`. r �s ;,j 4: <br /> .i • ..
