i <br /> The primary source of hydrology for wetlands is provided by up-slope runoff, groundwater exfiltration, <br /> and flows from the creek. Groundwater flows from the Idaho and Cross adits are directed into pond #2 <br /> and contribute to wetland hydrology in the lower half of the property. Secondary sources are provided <br /> by naturally occurring side slope seeps, snowmelt, and precipitation events. <br /> 1 .3.4 Groundwater Resources: <br /> The proposed mine and its expansion area are not impacted by designated floodplains, because the site <br /> is located very near the headwaters of Coon Track Creek. Mining will be as presented in the original <br /> mine permit application. No impacts to ground water due to the proposed site modifications are <br /> expected. <br /> Groundwater at the site is generally controlled by drainage out of the existing mine adits, which report <br /> to two ponds for the addition of lime and discharge to Coon Track Creek through a permitted discharge <br /> point, and by discharge to stream channels, seeps, and springs. <br /> Waste rock analyses previously performed and part of the Division's existing permit file indicate the host <br /> rock and ore are non-acid generating. Ground water pH based on three quarters of analysis has been <br /> between pH 6.4 and 7.6 in the three domestic wells. <br /> The waste rock analyses and pH of the ground waters sampled at the three domestic wells indicate the <br /> waste rock is benign and there should not be a ground water quality issue. GIR is updating its Water <br /> Sampling and Analysis Plan. <br /> 2 References <br /> O'Shea-Stone, M. and Ash,J. 2008.
