We worked with <br />a couple of different options to see if we couldn't realistically <br />lower the reclamation bond. I have the following suggestions for <br />your consideration: <br />1. On the reclamation of benches we recommend the use of <br />three trucks (the optimal number in your model) for the placement <br />of growth material. We estimate this job cost to be $13,629.00. <br />2. On the reclamation of the quarry floor we recommend the <br />use of a Cat 623B scraper instead of a Cat D8N. Both pieces of <br />equipment cost the same hourly rate, but with the scraper we can <br />increase our adjusted unit production to 350 LCY/hr. This should <br />reduce our total job cost for this phase to $15,410.00 <br />Take a look at these proposals and see what you think. I've <br />enclosed our notes for your review. <br />Thanks again for all your help and continued support. <br />Respectfully, <br />ob Stack <br />Manager, R.C.L.L.C. <br />
