Box 560 <br />Rye, Colorado 81069 <br />Attn: Mr. Joe Baxter <br />Re: Geotechnical Stability Exhibit <br />Sikes Pit, Section 7, T33S, R50W <br />Colorado <br />Dear Mr. Baxter. <br />In accordance with your request, this firm has reviewed the blasting plans for the <br />development of the referenced pit. It is understood that the pit will consist of a <br />rock quarry that will be located near the center of Section 7, Township 33 South, <br />Range 50 West, in southeastern Colorado. The quarry will be used for the <br />production of construction aggregates. The object of our review was to evaluate <br />whether the blasting activities will have an adverse affect on any permanent <br />man-made structures in the vicinity of the proposed quarry. <br />It is our understanding that the only permanent man-made structure in the nearby <br />vicinity of "the quarry is the Sikes residence. That residence is located <br />approximately 1.1 miles to the east-northeast of the proposed quarry and is <br />approximately 200 feet lower in elevation. The proposed blasting for the quarry <br />will involve drilling 5 inch diameter blast holes to depths of about 40 feet. The <br />holes will be spaced at approximate 11 foot centers. It is further understood that <br />the maximum charge weight per delay will be on the order of 650 pounds. <br />Based on the relatively low charge weight per delay along with the distance away <br />from the blasting activities of the nearest man-made structure, it is our opinion <br />that the blasting will have little to negligible affect on the Sikes residence, either <br />from ground motions or air pressures. <br />Should any question arise conceming the above, we would be pleased to oiscuss <br />them with you. <br />Respectfully submitted, <br />Geo-Test, Inc. <br />Robert D. Booth 4P.E
