~+t, L~~ h1 I N I NG F'LAN EXH 1 L~ I -i- D Mining of the M R G Git will be done ir. five phases. (See ® Exhibit C>. The five ^hases range from 13.1 tc. c1.8 acres ~~f the pr^oper•ty. They will each be stripped and all '~ overb~.rrden stockpiled aloha the property bo~_mdaries, After Phase I is mimed, waste fines and over•b~.irder~ fr•orn s~.~bsec~.rer~t phases will be used to backfill the North are es~~reiine pf this area. 'hase i serve as e p are site. ® Reclamation ~_ all phases will be done contemporaneously with the mining. The entire site has an average depth of 17 feet c,f sand aril er•avel deposits. Thirteen feet of this lies iri cood deposits and the r•emair~ir~g 4 feet ar•e sand ar~d clayey sand ~~ deposits. There are several areas where clay domes are irit er•s per^sed thro~_rgh the deec~sits. ',Jn er•e cr•act icai, these domes will be removed and ~_~sed for back.fill with waste sand. The underlying stratum f~:r this tleposit is a claystone that is hard to very hard, This claystone is ^ar•t of the Denver format ior~. There is a total of 76 acres that will be mined. EstLmated ® reserves that are mineable is adproxinrately 2,760,000 toms. This would arnount to 385,000 tens per year with a 7 year mine life. The mine life could vary dependir~e on the rnarN.et. There will be between 13.1 to 21.B acres of land under•gc~inq mining at any one time. Once mininb is completed ire each phase, reclaration will begin imrnediately. ~~~r mast phases, this will consist of sloping the shorelines and backfillind. R typical cr^oss section of the backfilled sh~_r•eline is shown in Figure E-1 ~_f the reclamation plan. The lama owner desires to have sc~rne of the or~~perty back.filled to create approxirnately ?.6 acres. TaSle D-i sh~~ws the dist ur•bance associated with each phase of the minino_ plan. ~j
