Access roads will be approximately twelve feet wide, and utilize pre- existing roads <br />wherever possible. Most of the locations will be accessible from the Yellow Creek Jeep <br />Trail (RBC 83), RBC 91, and from RBC 31 (see Figures 1A and 1B). Prior to any access road <br />utilization or construction (to allow for entry onto proposed locations) both BLM and <br />Landowner permissions will be secured as necessary. Two locations (K and O), which if <br />drilled, may require access via power line Right of Ways. Due to the temporary nature of <br />the locations, NSI is not planning on using hauled in materials to construct the access <br />roads, only native material. Accesses will be designed to reduce disturbance of forested <br />areas and existing drainages. A majority of the proposed locations are located in sage <br />brush parks, and not forested areas. Access will be cut at the edge of forested areas <br />whenever possible to minimize tree damage and disturbance. Alternative routes have <br />been noted where appropriate. Note that alternative routes will be an "either /or" <br />situation. If an alternate route is deemed more appropriate then another route will not be <br />constructed. The utilization of an alternate route could occur if, for example, it is <br />determined that a proposed well or wells are not needed and the alternate route could <br />provide access with less disturbance. <br />Drilling, Abandonment, and /or Completion <br />Most of the proposed core holes will be drilled and immediately plugged and abandoned. <br />The typical coring target interval will be from 10 to 20 feet above the Dissolution Surface <br />(DS) to 10 to 20 feet below the bottom of the Boies Bed. Some holes will core the entire <br />Saline Zone, or all of the nahcolitic oil shale from the DS down to the L -1 Zone. The <br />intermediate hole interval will be rotary drilled and temporarily cased using a 4.5 inch <br />scabliner. The coring medium will be a saturated brine of sodium chloride and /or sodium <br />bicarbonate to minimize saline mineral losses from the target interval due to drilling <br />induced dissolution. The saturated brine drilling fluid will be collected in lined pits or <br />containers if they exceed 5,000 ppm TDS. The target interval will be cored, and then the <br />scabliner will be removed and the well will be plugged and abandoned by cementing the <br />hole to surface. The core sample size will be HCL 2.5 inch, with a hole size of <br />approximately 3.83 inch. <br />Daub & Associates, Inc. NSI 2014 Exploration Program <br />Page 3 of 10 Revised 3/14/14 <br />
