Lochhead <br />Etecwive Dveaor <br />Michael B. Long <br />Division Dueaor <br />I have discussed with Harry Ranney in-house field equipment and <br />survey methods for completing an accurate survey of the pit area at <br />the Snowstorm Placer. As you know, it is very important to the <br />Division to have accurate measurements of the pit as soon as <br />possible in order to calculate a reclamation cost. The existing <br />mine plan map and aerial photograph from 1996 do not provide an <br />accurate representation of the pit as it exists today. <br />Harry informs me that a total station should be used to achieve the <br />highest degree of accuracy and efficiency for both horizontal and <br />vertical control. It takes two (2) people to operate the total <br />station and Harry is one of the Division's most experienced <br />operator's. Therefore, I request that we enlist Harry's help for <br />completing a survey of the pit. Two days of Harry's time will be <br />needed: one for the field survey and one for downloading data and <br />running the computer program in the office. <br />Please let me know soon if you agree with this assessment and if <br />permission is granted by Harry's supervisors. I can then <br />officially request Harry's help. Harry is willing to help me <br />perform the survey the week of August 11, 1997. <br />If all goes well, we will have a final reclamation cost for the <br />Snowstorm Placer prepared for the August 28, 1997 meeting at 1:30 <br />P.M. with Bernhard Free of Snowstorm Sand & Gravel, LLC. <br />Thanks for your help! <br />M:\oss\survey <br />
