10. Rule 6.5 Geotechnical Stability—Blasting <br /> a. A new engineering survey addressing blasting affects for blasting operations <br /> taking place in the May Day #1 underground workings was requested in the <br /> previous adequacy review. A new engineering survey was not performed or <br /> included. The survey that was resubmitted addressed blasting in the May Day #2 <br /> underground workings and is not consistent with the plans for blasting operations <br /> at the May Day #1. Please have a new analysis performed by a 3`d party licensed <br /> engineer to address the possible blasting effects from blasting in the May Day #1 <br /> underground workings. This analysis should include but is not limited to a <br /> narrative on the scaled distance calculations, details on the expected ground <br /> vibrations as well as a map showing the distance from the blast area to the nearest <br /> structure. The engineering survey should also review and assess the as built <br /> certifications for the portal and stabilization work that was performed at the May <br /> Day #1 portal in relation to the effects on the portal and its structures from <br /> blasting activities. <br /> Response: Please see Attachment 10—Blasting. <br /> Please let me know if you have any other questions. <br /> Sincerely, <br /> Sara Glinatsis <br /> Manager of Sunrise Mining, LLC <br /> sglinatsiskdiamondhi 11 farms.com <br /> 308-760-8925 <br /> 8 <br />
