Natural Soda LLC <br />2016 Resource Drilling Program (RDP) <br />Prepared for <br />Natural Soda LLC <br />by <br />Daub & Associates, Inc. <br />Grand Junction, CO <br />Introduction <br />Natural Soda LLC (NS) is proposing a 10 well Boies Bed, nahcolite resource definition <br />exploration program critical to NS's planning and future development. The wells will be <br />either cored or rotary drilled and logged. They will be drilled to further define the <br />thickness and areal extent of the Boies Bed nahcolite, halite facies, and other saline <br />mineral intervals in the Parachute Creek Member of the Green River Formation. Ideally, <br />only four to six wells would need to be drilled. If further data is required to sufficiently <br />evaluate the resource, up to 10 wells may be drilled. The majority of the wells that are <br />actually drilled will be plugged and abandoned, and the associated disturbance <br />immediately reclaimed. A few of the wells may be completed as groundwater monitoring <br />wells and/or subsurface subsidence monitoring wells, as applicable. <br />Rotary/Core Hole Locations <br />The proposed rotary/core holes are located within the 160 acre NS federal sodium lease <br />modification area. The well/pad locations will be scouted, staked, and photographed. <br />Pre-existing disturbance, ease of access, density of vegetation, and topographic relief were <br />considered while staking the locations to lessen the environmental impact and surface <br />disturbance of the operations. NS would like to be able to plan for and permit two drill <br />holes per location; an initial rotary/core hole and a contingency hole. The contingency <br />hole would only be drilled if it is determined more data is needed in the immediate <br />vicinity, i.e. if halite is found where only nahcolite was predicted or vice versa. The <br />contingency hole may also be drilled if unexpected operational problems are experienced <br />Daub & Associates, Inc. NS 2016 Exploration Program <br />Page 1 of 8 Revised 1/14/2016 <br />
