RECEIVED <br />EXHIBIT D <br />OCT 201983 <br />MINING PLAN <br />MINED LAND RECLAMATION DIVISION <br />Colo. Dept of Natural Resources <br />4.1 INTRODUCTION <br />Industrial Resources, Inc. (IRI) proposes to construct and operate a pilot <br />solution mine to recover nahcolite within NE 1/4, T1S, R98W in Rio Blanco <br />County, Colorado. The nahcolite will be extracted from the Boies Bed on <br />Bureau of Land Management (BLM) Sodium Lease No. C-01]9986. The nominal <br />production rate of the pilot mine will be three tons per hour and will <br />involve a total of five solution mining wells. The duration of the pilot <br />plant operations is anticipated to be one to two years. A general location <br />map is shown as Exhibit B. Details of the operation and associated schedule <br />are given below. <br />D.2 FACILITIES AND MINING METHODS <br />• The permit area for the proposed project will consist of 37.1 acres. The <br />Pilot Solution Mining Plant will consist of a recrystallizatio<n1~Cp/lant, <br />product load-out bin, three evaporation ponds, and a well field. F'LvC~ wells <br />will comprise the well field. The Pilot Plant is designed to/produce a <br />nominal three tons per• hour of nahcolite.(~eference Figure D-1) <br />D.2.1 Facility Construction <br />Surface facilities include a 58-feet by 96-feet recrystallization building, <br />and a 24-feet by 24-feet by 45-feet nahcolite storage/load-out bin (144-tan <br />capacity). The buildings will be steel construction over slab-on-grade <br />floors meeting Rio Blanco County's building codes. In addition, an 8-feet <br />by 26-feet trailer will be utilized for a shower and locker facility, and a <br />12-feet by 66-feet trailer will be utilized as an office facility. The <br />trailers will be jacked and blocked for stability. <br />D.2.2 Solution Mininrl Wells <br />S IJC <br />A total of~mining wells will be rotary drilled to a depth averaging <br />1,820 feet. The resultant two new cavities plus continued use of the small <br />D-1 <br />,T, ~,s <br />A ~~ Via` <br />
