o Transit Mix Concrete Co. <br /> Figure C-3 Geology Plan illustrates the location of exploration holes and various geologic zones <br /> identified after interpretation of the exploration data. The extent of the 3D geologic block model <br /> used for mine planning is also illustrated in Figure C-3. The exploration program confirmed <br /> regional geologic trends as observed from USGS maps available in the public domain. <br /> Creek Bed Fault Zone <br /> Inclined drilling below Little Turkey Creek indicated the presence of a significant zone of shearing <br /> and fault gouge below the creek bed. These observations were sufficient to define separate <br /> geologic fault zones that are interpreted to follow the creek bed as indicated in Figure C-3. <br /> Granitic basement rock was observed within the Little Turkey Creek fault zone, however the rock <br /> in general, is more fractured and includes intrusions of gabbro as results of the weakened rock <br /> fabric. <br /> East Fault Zone <br /> This zone is identified from surface mapping and aerial photo interpretation as a transitional zone <br /> between the Proterozoic basement rock in the west, confirmed by drilling, and the Cretaceous <br /> sandstone zone in the east, confirmed by surface mapping. Granitic basement rock was observed <br /> on surface, however there was evidence of abundant pegmatite veins reducing the suitability of <br /> this zone as a potential source of aggregate stone. <br /> Sandstone Zone <br /> Surface outcrop of sandstone was observed east of the East Fault zone as illustrated in Figure <br /> C-3. The sandstone is not suitable for aggregate stone and will not be mined. <br /> Basement Rock Zones <br /> The elevated ridges south of the Little Turkey Creek, as illustrated in Figure C-3, have exposed <br /> on surface uplifted basement rocks comprising mostly granite, diabase, and granite gneiss. These <br /> rocks are similar to what is described as granodiorite from detailed mapping completed by the <br /> USGS on the Cheyenne Mountain quad (Rowley et al., 2003) located east of the property. The <br /> USGS has not completed any detailed mapping of the Mound Big Chief quad that covers Section <br /> 16 of the property. These basement rock zones are described as follows from west to east across <br /> Section 16. <br /> South Ridge Zone <br /> The zone includes the area south of the Little Turkey Creek up to where the basement rock <br /> transitions into younger Cretaceous sandstone across the east fault zone as indicated in Figure <br /> C-3. The basement rock in the elevated ground above the Little Turkey Creek is predominantly <br /> granite, diabase, and granite gneiss. The granite typically has abundant plagioclase crystals that <br /> impart a reddish color to the rock. There are occasional pegmatite veins that appear to be more <br /> abundant nearby the east fault. Deformation in the basement rock results in an abundance of <br /> Hitch Rack Ranch Quarry Permit Application <br /> March 20,2018 D-20 <br />
