1. SITE LOCATIONS & GEOLOGY All maps haae Lat. /Long. Coordinates measured at the entrance of the permitted or leased area. 2. The Stocks Mine: (Permit # M-1977-324) Mau 2. shows the general location of the Stocks Mine, accessible from Canon City, via Field Rd. north of US Highway 50 approximately3.8 miles, turning left to private road of Stocks, going west crossing Wilson Creek Fremont, County. Further, the map shows streams, roads, utilities, wells, all dwellings with in 3000 ft., and other structures. There are no dwellings and wells within 3000ft. of the proposed blasting. The geology consists of the clays and shales (actively mined) of the Glencairn Formation, Dakota Group. Extensive published geological work has mapped the Dakota Sandstone Group with the associated clays throughout Fremont and surrounding counties. Near the middle of the Dakota Group lies the Glencairn Formation, which contains shales and clays, which have brick making properties. Site specific geology indicates that the Dakota strikes approximately N 75~ W, and has a +/- 22~ dip to the southwest, existing as an un-eroded island several hundred ft. above the alluvium of Wilson Creek, and other surrounding formations. Local wells are not producing from the Dakota Aquifer. It must be pointed out that the Dakota Group rock strata which is targeted for blasting at this site is completely separated from the farm and ranch land to the south, by a deep canyon cut by Wilson Creek. The mining is being conducted at approximately 6000 ft. in elevation, where as the farm and ranch land below lies at 5600 ft, to 5800 ft. Lonnie Loader Construction of Penrose, Colorado normally conducts blasting. Overburden consists of thin poorly cemented sandstone and shales about 5 to 15 feet thick. Due to the nature of the softness of the clays below the blasting level, a portion of the blast impulse is absorbed on site. Blast holes are usually 3.5 in diameter with an average depth of 8 ft on 8 foot centers. All holes are stemmed with 2 feet of dirt, thus powder thickness is usually less than 5 feet. An Ez-Det. delay system is incorporated with 25/350 milliseconds is used combining 2 holes. Mr. Loader is always striving to maintain his high level of expertise, by staying abreast of timely changes with in the blasting industry, where new techniques and devices are introduced as proven to aid in blasting to eliminate vibration and noise.
