This was based on a very conservative <br /> approach where cross-country overland travel for a temporary access road to a drill pad was calculated <br /> at 100%disturbance. For example,if a proposed cross-country road is to be 200 feet long,then the <br /> surface disturbance was estimated at 200 ft x a 10 ft width, or a disturbance of 2,000 (0.046ac). A <br /> subsequent discussion in the field between myself and Ryan Joyner,BLM Tres Rios Assistant <br /> Manager for Land and Minerals on this NOI, indicated that they thought this approach was unrealistic. <br /> They felt that the 100%approach was appropriate for where mechanized equipment dropped a blade <br /> or used a bucket to create accessways, and that a 30%disturbance factor was more suitable for <br /> overland travel. <br /> Given that the nature of the terrain at the-Sec. 23 Project Area is suitable for cross-country travel to all <br /> of the proposed drill pads, Standard Minerals would like to propose a reduction in estimated <br /> disturbance calculations from 0.94 acres to 0.73 acres. Please see Table 1 and Figure 1 below. For <br /> consistency, all drill pads are considered to be 100%disturbed. <br /> The reduction of surface area also affects the bond calculations. The original volume measurement of <br /> 1,511.1 yd3 would be reduced to 1,176 yd3 if the access road calculation are modified to a 30% <br /> disturbance <br />
