GoodMiller #2 Pit 112c Permit <br />Table D -1: Mining Areas <br />It is important to note that the areas listed above are estimated areas to be mined. The total permit <br />area is larger than the sum of the mining areas, but this may change if the daylight edge of the <br />mining moves based on geologic conditions experienced during mining. The total expected gravel <br />to be produced is 5,613,000 tons over 8 years. <br />The material volumes described in Table D -1 are approximate but are based on the current <br />operation and estimated gravel extents. The "Years to Mine" column is based on an average annual <br />production of 500,000 tons per year of sales and 0% reject fines. Sales will always be dependent <br />on demand so mine life may change. Area 1 volume remaining is based on the area mined out as <br />of October 2014 from the original GoodMiller Pit (from Map C -1 vs Map C -2). Additional volume <br />has been mined since that time. <br />Table D -2: Mining Areas and Quantities <br />GoodMiller #2 Pit Dec 2014 D -3 <br />To be Excavated <br />To be Placed <br />(Map C -1 to Map C -2) <br />(Map C -2 to Map F) <br />Topsoil <br />(@ at <br />Overburden <br />Minimu <br />Topsoil <br />Acres <br />(@ at 2' Gravel <br />Total <br />m <br />(@ if <br />6' <br />depth) <br />Backfill <br />depth) <br />depth) <br />27.0 <br />10 <br />47 1,290 <br />1,399 <br />67 <br />22 <br />19.7 <br />16 <br />64 391 <br />470 <br />3 <br />16 <br />39.9 <br />32 <br />129 1,320 <br />1,481 <br />25 <br />32 <br />26.7 <br />22 <br />86 284 <br />392 <br />12 <br />22 <br />134.68 <br />81 <br />326 3,285 <br />3,742 <br />107 <br />91 <br />* Area 1 has been already been only partially mined. <br />GoodMiller #2 Pit Dec 2014 D -3 <br />
