<br /> <br />1 <br /> <br /> <br />1 <br />1 <br />MINING L='LAN <br />EXHI]~I-1- 1? <br />Mining of the M & C; Pit will be done in five phases. (See <br />Exhibit C>. The five phases range from 13.1 to 21.8 acres <br />of the property. They will each be stripped and all <br />overb~_rrden stockpiled alnr~p the property boundaries. Rfter <br />Phase I is rnined, waste fines and overburden firorn subsegr_rent <br />phases will be used to ack.fill the North ari e~hc~reline <br />of this area. Phase o serve as e p ari site. <br />Reclamation o all phases will be done conternpuraneo~.rsly <br />with the mining. <br /> The entire site has an average depth c.f 17 feet of sand and <br />' eravel deoosits. Thirteen feet of thi s lies in pond <br /> deoosits ar~d the r•ern airiir~q 4 feet ar•e sand ar~d clayey sand <br />' deposits. There are <br />iriter•spersed through several areas where <br />the deposits. 4Jher•e clay Burnes are <br />practical, these <br /> dornes will be removed ar~d used fnr• backfill with waste sand. <br /> The ur~der•lying str•at urn f~~r• this deposit is a claystone that <br />' is hard to very hard. This claystone is par t of the Denver <br /> format iori. <br />1 <br /> <br /> <br /> <br /> <br />1 <br /> <br /> <br /> <br />There is a total of 76 acres that will be rnined. Estimated <br />reserves that are mineable is approximately 2,760,000 toms. <br />This would anruurit to 385,000 tons per year with a 7 year- <br />mir~e life. The mime life could vary dependirip on the <br />rnarket. <br />There will be between 13.1 to 21.8 acres of land ur~der•gair~g <br />rnir~ing at arty one time. Once mining is completed ire each <br />phase, r•eclarnation will begin irnmediately. cor• mr_~st phases, <br />this will consist of sloping the shorelines ar~d back.fillir~p. <br />R typical cross section of the backfilled shoreline is shown <br />in Figure E-1 of the reclarnatior~ plan. The land owner <br />desires to have sc~rne ~~f the property backfilled to create <br />approximately 9.6 acres. <br />Table D-1 shc.ws the disturbance associated <br />of the mining plan. <br />D-1 <br />with each phase <br /> <br />
