Mr. Peter Page 4 September V. O'C nor 23, 1985 189,350 cubic feet of underground storage area with a capacity of 1,416,000 gallons of water. A wall rock sample of Boulder Creek granite was taken from the face of the Time mine near the Wynone winze. It has been delivered to the Hazen Research Laboratory in Golden; Colorado, and a total chemical analysis is being performed to determine pos- sible contamination. As soon as the results from this sample ere obtained, a copy will be forwarded to the Mined Land Reclamation Division. The following averaged chemical compositions of Boulder Creek granite were taken from data published by the U.S. Geo- logical Survey. SiO2 - 66.0% Na2O - 3.3% A12O3 - 16.0% K2O - 2.5% Fe2O3 - 1.9% MnO - 0.1% FeO - 2.0% H2O - 0.7% MgO - 1.4% TiO2 - 0.7% CaO - 4.8% P2O5 - 0.8% These are averaged analyses of 7 samples that were grouped to facilitate compositional variations within the Boulder Creek granite near Gold Hill, Colorado. 3. A sample o[ the water flowing in Lett Hand Creek was taken from the creek near where the pump will be situated. It was delivered to the Hazen Research Laboratory in Golden, Colorado, and an analy- sis of the water is being performed. The Gold Hill Ventures Limited Partnership has discussed water monitoring methods with the Lett Hand Ditch Company, end plans to sample the creek above and below the point of diversion. 4. Gold HiH Ventures intends to draw water from a point of diversion located on the south bank o[ Left Hand Creek. The pumping station will occupy a 15 by 20 toot frame building, near a site with an existing access road and power source. Water will be pumped 3,900 feet up Akins Gulch in a 2 inch diameter pipeline that will be placed on the surface of the ground on the east side of an existing mine access road. The water line will follow this road until it reaches a point beneath the Gold Ring mine dump, where it will run directly uphill to the Time mine's portal. The total amount of )and surface that will be affected by the construction of the pumping station is 0.013 acres. As we discussed at our meeting on September 18, 1985, the pipeline will not be buried, and its assembly will not disturb the lend surface. We ere en ng topographic map showing the location of the pumping tion, and a are increasing the total acreage of affected land to 7.638 ecr s to encompass this additional area within the permi boundary (Se Map B3).
