<br />Five-minutes at the site would go a long way toward convincing you of the <br />validity of the above statements. We would be glad to accommodate you on a <br />site visit. <br />Hydrology <br />Your Questions: <br />1. Has there ever been a discharge from the mine entrance due to fluctuations in <br />the water table? <br />Answer: No. <br />2. What is the recorded fluctuation of the ground water table for the area? <br />Answer: The fluctuation of the ground water table has never been documented. <br />However, general observations from the very infrequent trips down to the flooded <br />levels of the mine indicate that the water table might fluctuate ± 6 inches. <br />You also requested one complete suite analysis of water quality data from the <br />lower levels of the mine before operation commences. <br />Response: We will comply with that request, but before we do that we need to <br />know exactly which analyses you require. <br />Your Requests: In addition, please provide the following: <br />1. The depth and gradient of groundwater beneath the permit area. <br />Response: The depth to groundwater was stated in the permit and <br />acknowledged by you in the adequacy letter to which we are responding. You <br />correctly read that the elevation of the groundwater in the Smuggler Mine is <br />approximately 105 feet below the collar of the Smuggler shaft. You incorrectly <br />read that the elevation of the Clark and No. 2 Tunnels (there is no No. 23 Tunnel) <br />is 65 to 70 feet above the phreatic surtace. The permit states that the elevations <br />of the Clark and No. 2 Tunnels are 65 to 70 feet above the collar of the Smuggler <br />Shaft, which means that the phreatic surface at the Clark and No. 2 Tunnels is <br />about 170 to 175 feet below the ground surtace. <br />We have not measured the groundwater gradient. <br />2. Any perched aquifers or other contiguous ground water bodies that are <br />separate from the regional groundwater. <br />Response: There is no indication of perched aquifers or other contiguous <br />groundwater bodies that are separate from the regional groundwater. <br />3. All surface streams <br />
