The vast majority of this consumptive use is supplied by existing water rights that Golden Cross <br />has from the Sacramento Ditch which enters the site from the 6" pipeline as shown on the revised <br />Map C -2. These water rights consist of 2.0 cfs from the Sacramento Ditch pipeline that is <br />designated for mining related uses only and 2.0 acre feet that was sold to Golden Cross with the <br />property for any development use. Documentation on these water rights is given in Appendix 1. <br />However, since new groundwater exposures have been made, a Gravel Well permit and Substitute <br />Water Supply Plan is needed for the pit exposures, according to the local Water Commissioner <br />with the State Engineer's office in Fairplay, CO. This Well Permit Application and SWSP data is <br />included in Appendix 1. <br />According to the HASP approved augmentation plan for users along the Middle Fork of the South <br />Platte River, there is no lag depletions if the uses are within 1000 feet of the River. As seen from <br />Map C -2, all the ponds are within the 1000 feet to the River. <br />Since the Sacramento Ditch generally flows from late April to October in a normal year, this more <br />or less coincides with the time that the operation is active. The ground water exposures in the <br />ponds will remain when the pit is not active but these ponds are mostly frozen from late <br />November through early May in a normal year at this elevation. Taking this into account, it is <br />conservatively assumed that the operation will need to supplement the 2.0 cfs right by purchasing <br />50% of the total consumptive use. This is an amount of 2.22 acre feet based on 50% of 4.44 acre <br />feet total use. This amount will be purchased from HASP on an annual basis through a lease with <br />them, using their approved augmentation plan. <br />A new revised Mine Plan Map (Map C -2) has been created to reflect the current status of the site <br />and to show the future mine areas. This Map is attached to this technical revision. <br />Placer mining will be undertaken by digging a pit down to bedrock of no more than 9000 square <br />feet of water exposure. Subsequent pits will be excavated and some gravel will be processed in a <br />portable plant on site for sale and other gravel will be backfilled over the previous pit for <br />reclamation. <br />
