1 <br /> ' The location of these two monitoring wells are noted on <br /> Map A. <br /> ' Preoperational monitoring to establish the baseline <br /> ground water conditions which existed prior to the onset <br /> of milling activities has been accomplished. On March <br /> ' 25, 1987, Gold Hill Ventures' staff obtained water <br /> samples from the four wells that will be used to monitor <br /> the amount and quality of the ground water in this part <br /> ' of the permit area. The attached Reports of Analysis <br /> from Hazen Research, Inc. , of Golden, Colorado, includes <br /> total dissolved solids, and laboratory parameters of <br /> sulfate, iron, copper, lead, zinc, silver, mercury, <br /> ' arsenic, and cadmium. The field parameters that Gold <br /> Hill Ventures obtained of the water level, pH, and <br /> temperature for the four monitoring wells are noted on <br /> ' each Report of Analysis. <br /> Operational monitoring will be conducted during the <br /> ' life of the milling project on a quarterly basis, unless <br /> it can be demonstrated that potential ground water <br /> contaminants are not migrating downgradient from the <br /> tailings impoundment area. Two samples of the mill <br /> ' tailings were analyzed and the results submitted to the <br /> Mined Land Reclamation Division during the first year of <br /> milling operations. If the type of flotation reagents <br /> ' are changed during the life of the project, additional <br /> mill tailings samples will be analyzed and the results <br /> forwarded to the Mined Land Reclamation Division for <br /> ' comparison with the water samples from the monitoring <br /> wells. Mill operators will sample the mill tailings <br /> water for the following parameters: field parameters of <br /> pH, temperature, electroconductivity or total dissolved <br /> ' solids; and laboratory parameters of sulfate, iron, <br /> copper, lead, zinc, silver, mercury, arsenic, cadmium, <br /> xanthate concentrations, and any other mill chemicals <br /> ' used in our processing facility. <br /> The U. S. Bureau of Mines test well located closest <br /> to the Cash mine access road was selected for the <br /> ' purpose of monitoring the ground water level and <br /> chemistry of the water that will be stored in the Hazel <br /> A. edit. The preoperational water sample obtained on <br /> ' March 25, 1987, defined the baseline conditions which <br /> exist in this area prior to storing any decanted mill <br /> water in the Hazel A. adit. <br /> ' 15. There is a pre-existing permanent diversion ditch <br /> that is being used to protect the tailings pond from <br /> water runoff from the precipitation catchment area above <br /> ' the tailings impoundment structure. This water runoff <br /> diversion ditch was constructed according to the design <br /> submitted to Gold Hill Ventures by Ted Zorich and <br /> ' Associates, Inc. , of Englewood, Colorado. <br />
