• to prevent hole squeezing, a water mist will be utilized to allow the hold sides to pack in <br />and stabilize. Water will be carried to the site in a 2000 to 3000 gallon tanker and a <br />portable mud pit will be used to inject water into the drilling air stream. The drilling unit <br />would be a 2 -1/2 ton to 5 ton type truck with a Mayhew 1000 or equivalent type drill <br />mounted on the truck. There will also be a tool truck (2 -1/2 ton flatbed) and pickup for <br />crew transport. A logging unit will also be used and is typically a suburban-sized <br />vehicle. KMG will also have a 4x4 type vehicle for the project geologist and additional <br />transport. <br />The core holes will utilize the same equipment except that the hole will be drilled down <br />to 1' above the lignite seam. At that point a core barrel and core bit will be mounted and <br />the drill will penetrate the lignite seams and recover a solid core of approximately 2 -1/2 <br />to 3 inch diameter. The geologist will immediately describe the core and package the <br />core for transport to a laboratory for analysis. <br />To the extent possible existing two track roads will be used to access sites. Where <br />necessary, the trucks will drive over virgin ground to access the site. No new road <br />construction is anticipated and no diversion of overland flow is planned. <br />At the drill site, activities will be contained in an approximate radius of 50' from the drill <br />hole. Drill cuttings not used in the reclamation process will be broadly scattered to less <br />than 1" depth. All trash will be removed from the site area upon completion of the hole. <br />• Location of Topsoil Areas <br />There is no expectation of removing topsoil at any of the drill hole sites. <br />Earth Moving for Roads and Drill Sites <br />There is no intention to develop roads or drill pads, therefore, there is no earth moving <br />required. <br />Seed Mixture <br />The recommended seed mixture by the Simla NRCS and Department of Agriculture is <br />shown in Exhibit D . They consist primarily of dry land grasses. <br />Depth of Drill Holes <br />Exhibit E is a table of drill holes and their expected depth and the amount of coring <br />expected at each cored location. In general, most of the holes are less than 120' in depth. <br />The pilot holes will be sub - drilled between 8 to 10 feet depending on the geophysical <br />probe utilized for logging the hole. <br />1 <br />-10- <br />
