Transit Mix Concrete Co. <br /> The only exposed fault in the proposed mining pit is the west fault. The west fault is high angle <br /> fault that is striking approximately northeast-southwest and forms part of a series of similarly <br /> trending faults oriented parallel to the Front Range. The surface trace of the west fault can be <br /> seen in Figure C-3 geology plan and in Figure C-11 that illustrates west-east cross-sections <br /> across the pit (section B-B'). The west fault is interpreted to be a narrow (less than 2ft) and tight <br /> fault zone that is not expected to have a material impact on the mine plan. <br /> East of the west fault are a series of high angle faults that form part of the east fault zone as <br /> indicated in Figure C-3 geology plan. The fault zone forms part of a transition zone from granitic <br /> rock in the west to sandstone in the east. None of the east fault zone faults are exposed in the <br /> proposed mining pits and these faults have no impact on the mine plan. Exploration drilling and <br /> mapping has also identified the main drainage of Little Turkey Creek to be located above zones <br /> of faulting or shearing. The weakened rock fabric below these two drainages are not planned to <br /> be mined or exposed in the proposed mining pit. <br /> Topography and Drainage <br /> The area of interest for surface mining for aggregate stone is in the northwestern half of the Ranch <br /> property which covers Section 16 of Township 16 South, Range 67 West, 6th P.M., El Paso <br /> County, CO. Figure C-3 Geology Plan illustrates the surface topography contours for the <br /> proposed Quarry within Section 16. Here surface elevation varies from a maximum of 7,720 feet <br /> to a minimum of 6,770 feet in the east in the Little Turkey Creek riverbed. The Ranch property is <br /> bisected by the Little Turkey Creek which drains towards the east from its source in the Front <br /> Range mountains in the west. Within Section 16 the Little Turkey Creek valley floor elevation <br /> varies from 7,060 feet in the west to 6,770 feet in the east. The proposed access road extends <br /> south from Section 16 before heading east across the gently sloped, lower, and eastern half of <br /> the Ranch property. The access road crosses Little Turkey Creek at an elevation of 6,580 feet <br /> before connecting with State Highway 115 on the eastern extent of the affected lands. <br /> Exploration <br /> Surface mapping and exploration drilling in Section 16 was completed by Transit Mix in 2014 and <br /> Norwest Corporation in 2015 and 2017. Six (6) vertically orientated shallow core holes were <br /> completed in 2014 and seven (7) vertical and angled holes were completed in 2015. Seven <br /> boreholes were drilled in 2017, and these wells were completed as groundwater monitoring wells <br /> or piezometers. Core samples taken from the drill holes were tested for rock strength properties <br /> for surface mine planning and to determine the suitability of the rock for a sized aggregate stone <br /> product. The 2015 and 2017 programs included downhole geophysical log measurements that <br /> included an acoustic and optical televiewer for fracture/joint orientation analysis and density, <br /> natural gamma, and electrical resistivity measurements for material properties and changes in <br /> rock type (only 2015 drill program). Data acquired from the surface geologic mapping and <br /> exploration drill holes was used to construct a 3D geologic block model of Section 16 using <br /> MineSight'rm software. <br /> Hitch Rack Ranch Quarry Permit Application <br /> March 20, 2018 D-19 <br />
