7. A review of USGS seismic histories of this area show no recent fault movements <br />or earthquakes within historic time frame. Those areas in Southern Colorado that <br />have experienced earthquake tremors are located in the Raton Basin near the New <br />Mexico border and have been associated with deep waste water injection wells <br />operating in methane gas recovery operations in that region. The fault zones mapped <br />in the southern Front Range area have been aged dated between 15,000 to 130,000 <br />years ago and apparently do not rate a concern from earthquake risk assessors <br />evaluating current risks of earth tremor. The .15 risk coefficient factor used is the <br />same as used for all front range estimations unless local conditions (or uses, per <br />above) warrant a different co -efficient. <br />8. The eastern margins of the permit area both north and south of the east/west <br />drainage that crosses the area is considered active mining area at this time and will <br />continue to be evaluated for potential resource extraction over the next number of <br />years of mining of the main granite resource lying west of the granite/sedimentary <br />unit contact (shown on the highwall study map). The 2013 reclamation map reflects a <br />maximum build out final scenario which will be modified based on landscape rock <br />demand, economics, and geographic considerations prior to mining this area. Once <br />these factors critical to decision making regarding mining of the southeast corner of <br />the permit area have been clarified, a detailed final highwall plan for this area will be <br />submitted for Division review and approval. <br />If you have any questions regarding the above responses, please do not hesitate to <br />contact me. <br />KSKIco <br />Consulting Geologist <br />Azurite, Inc. <br />
