~-~ • Adequacy Letter Page 2 had incurred same problems with tailings pond collapse we would have already made the necessary engineering studies. We have never held nor do we expect any tailings pond problems, thus we cane not agree to this request, If the State of Colorado wishes to employ sin independent engineering firm (at the states expence) to inspect the present and future tailings pond and our mechanism for the construction of said pond feel free to do so. Make sure that Camp Bird Colorado, Inc, knows which firm will be doing the inspection and when the inspection will take place. Also, make sure the ins{:action team has the proper personal safety protection equipmecit as required by state and federal laws. 5. Sailinga; pond construction: Moat tailings pond berms are constructed of the c:oarae material contained in the tailings slurry. Approx- imately 10~, of the slurry is composed of 50 mesh or lager sand grains. This material is separated by a system of cyclones and placed on the berm. 7'he compaction of the berm is accomplished when the coarse material. is dewatered. Occasionally additional material ie used as berm material, Thia material meet the standards for berm contraction. 6. On site runoff: Runoff will be controlled by ditches, rip rap and seeding, At Present we have no runoff problems. Problems which ma.y occur in the future will be handled appropriately when they occur. EXHIBIT E - RECLAMATION PLAN We will do whatever ie required by the appropriate state,federal, or local agency to reclaim this operation at that future date when mining operations cease. In another 100 years many new substances and seed mixtures will be found which may lessen costs and the time involved in the reclamation process. The grade of dump~and tailings slopes cannot be determined at this time as they are unknown. We contacted the Soil Conservation Service in an effort to obtain ideas for possible revegation and grading, but for us to say we will use any particular reclamation method is unwise for both Camp Bird and the State of Colorado. We will Do Whatever is required by the proper authority at that time when mining operations are abandoned. EXHIBIT F - RECLAMATION PLAN MAP For us to estimate even the approximate contours of graded areas, drainage diversions, etc. we would have to know the amount of tailings added to the pond, the amount of rock brought to the surface and numerous other figures which by the very nature of hard rock mining are impossible to determine. We will Do Whatever is Required by those in charge at the time mining operations are abbandoned,
