This request is submitted pursuant to C.R.S. 37-92-308(4), <br />referencing the plan for augmentation applied for in case no. 06CW91, for Water <br />Division 7. Notice has been provided to those listed on the Division 7 SWSP <br />notification list. That notice was sent on December 21, 2006 and no comments <br />were received during the 30-day statutory review period. The required fee of <br />$300 has been received (receipt number 3611940). <br />PLAN OF OPERATION <br />Wildcat Mining Corp. is a small mining operation in La Plata Canyon, in La <br />Plata County, Wildcat has purchased a patented mining claim, and intends to <br />mine for gold and silver within the Idaho mine, and reopen a mill site near the <br />portal of the mine. A water rights application, including an augmentation plan, <br />has been filed in the Division 7 water court, case no. 06CW91. No decree has <br />been issued to date, thereby necessitating an approved SWSP from the <br />Colorado Division of Water Resources. Wildcat proposes to use surface water <br />from a nearby stream channel, where a diversion point will be established. <br />Water will be diverted from this structure to the mill. From the mill outlet, water <br />and mill waste will be conveyed to a settling pond. From the settling pond, water <br />will be recycled back into the mill. The milling process will result in a 100% <br />consumptive use of the water. Since the La Plata River is over appropriated, <br />Wildcat will augment depletions during periods of river call. Wildcat proposes a <br />pond in which augmentation water will be stored, for releases when the river is <br />on-call. The pond will be filled when Wildcat's water right is in priority. If <br />insufficient water is available for release from the augmentation pond to cover <br />depletions, operations at the mining site will cease.
