Exhibit "C" Exploration License No. COC -74911 with those of surrounding areas. We do not anticipate any unique values or resources of special concern. Soils on the ridgelines and steep valley sideslopes are generally shallow and rocky with deeper, more developed soils in the valley bottoms. Soils vary in thickness and generally contain a high percentage of rack fragments interbedded with clay and siltstones. Biology: Vegetation cover types are projected to be consistent with the terrain and semi -arid climate found on the upland area, with mountain shrubland (Juniper, Gambel's Oak, (waking Aspen, Big Sagebrush, and various grasses as the primary species), Juniper - Woodland (Juniper, Oak, Mountain Snowberry, Saskatoon Serviceberry, and Mountain Mahogany as the primary species) vegetation types being the dominant varieties. A wide range of wildlife species are projected to inhabit the general area, although use and habitat values maybe limited by the semi -arid climate and terrain and vegetative cover types. The area will be evaluated for applicable T&E and sensitive species per license requirements. Cultural Resources and National Register of Historic Places The area will need to be evaluated for cultural resources before drilling occurs. Typical drilling meth ods and�activi th at may occur during the exploration drilling process Oxbow Mining, LLC expects to drill 43 exploration drillholes as shown on Table I below. This table provides a summary of the proposed exploration hales. The attached map (Plate 2) Oak Mesa Project, Proposed Drilling Program shows the projected drilling locations. Once the exploration application and State NO to drill have been approved, drilling will commence as soon as weather and ground conditions and surface access agreements allow. The drilling season is expected to last from late March to Mid November, but may vary depending upon weather and surface owner access agreements. Drilling is projected to consist of at least two crews per drilling rig drilling 10 -12 hr. days with four days off. Drilling equipment is projected to consist of a PortadrilI TKT sized rig that can complete both rotary and coring activities with the same rig. All drilling equipment will be inspected to ensure that appropriate safety equipment is available should the need arise. Supporting that rig will be a 4000 gal water truck, a flatbed truck with drilling supplies, and an E -log truck for running digital logs of each drill hole and two pickups for crew transportation. Excavated earth or debris- disposal activities: Sites, whenever possible, will be accessed using existing available light duty pre - existing ranch roads. When roads are not available, temporary roads will typically be constructed using a grader, which will blade using sidecast methods an approximate 12 foot wide running surface. Road construction estimates are based upon currently available satellite photographs. Drillhole locations maybe adjusted slightly in the field to optimize the placement of the drill pad. Light use roads and road construction distances may be adjusted to represent the more current information. Most existing road alignments will not require modification, but may require road maintenance consisting of grading the road to provide a smooth operating surface, clean -out and repair of any existing drainage ditches and application of temporary drainage control measures (berms, straw bales, silt fences, gravel surfacing, etc.) as necessary. New road construction will be kept to a minimum and will follow applicable BLM specifications. Following the conclusion of drilling activities, the temporary roads will be obliterated by grading to approximate original contour and distributing the rock, brush, soils, etc pushed along the sides of the road back across the road corridor. Total estimated disturbance is 21.5 acres for Forty -three (43) drill pads and 14.29 acres for roads for a total disturbance of 35.79 acres. August 26, 2011
