~~. `- YY~ ~~ ~~ r~ w r~ TUTTLE APPLEGATE RINDAHL, INC. Consultants for Land and Resource Development Mr•. Rick. Everist, Jr. L. G. Everist, Lnc. July 15, 1988 Pade 2 The mining area c~~nsists ~~f an alluvial de p~~sit. This de p.~sit as described by the U. S. G. S. c~~ns lsts mainly ~~f sand and er•avel, some beds si lts and clays, and s~~me scattered c.~bbles ar,d boulder^s. This allravi unr at the nr >_ning site is thin and generally d~~es rn~t exceed 1rB feet in thickness in m~~st places. The mast ere lrst or the Division ~~f Water Res~~r_rr•ces f.~r• well. permits cent ains s~~nre well depth and water level inf•~rrrrat i~~r~ for permitted welts in the area. This infor•mati~~n was ~~r•ioinaily compiled fr~r• the £xhiblt G tlata used in the appl iCat i.~n t~~ the State Mined Land Recianrat ion Division. Nine of the well per•mit_:; sh~~wed the depth tt~ groundwater. Tfie depth t~~ groundwater rangetl fr•onr 19 to TS feet. Most of these wells appear to draw their supplies either from the terrace deposits or the Ogallala formation. q few wells midht get water from fractures in the Brine formation. Most cif the wells in the area are located in ore ar•~~und the Commranity of Carer, Co lor•ado. The surface etevat ion fore thesee wells varies from S, TiDO to 5, 74rP Teet MSL. Division .~f Water• Resources information shows the wells to range in depth from 3i:.'. to 'c^85 feet. Dosed on tfi is inf~~rmat ion, the groundwater table appears to be deeper than the proposed depth oY' nri nine. In addition t~~ these wells, 4rD test holes were drilled on the property for resource enalysis. These test holes ranged in depth from 4.5 feet to i'c' feet, depending on the depth of the sand and gravel resource in the area. Gr•oundwatere was not encountered iri any of the 40 fioles that were drilled. The proposed mining operation is situated approximately 'c7 feet: above tone Tree Creek in a terrace tlep~~sit. Rem~~val of material to a depth of 14 feet and r•epiacenrent of usable material woulcl place the mining ~~perat ion cc feet ab~~ve the stream channel. Dosed on the available r•ecor•ds from the State Eng ineer• and the U. S. Ge~~logical Survey and also on the eleveti~~n of the mining oper•aLion relative to the Lone Tree Creek channel, it appears: conclusive that no groundwater will be exp~~sed during the mining operation.
