Charted cyanide levels appeared related to the Lab MDL. No significant changes were noted, <br />however, in the analytical data with nothing to suggest adverse impact by the Elk Creek Mine or <br />Sanborn Creek Mine to the River. <br />The water flows for the North Fork are obtained from the USGS Gauging station located on the <br />river upstream of the mine. Discussion took place with USGS regarding the future of the station <br />in light of funding challenges. If the data from the station becomes unavailable, some other <br />mechanism may have to be employed for flow data. <br />HN -1 —Lower Hawk's Nest Creek <br />Surface water monitoring site HN -1 Lower Hawk's Nest Creek, is monitored to verify that the <br />Sanborn Creek Mine does not have an adverse effect on the quality or quantity of runoff from <br />this ephemeral drainage. During 2013 there was, again, minimal flow in Hawk's Nest Creek <br />during spring snowmelt, and no flow after snowmelt was completed. Higher sulfate levels seen <br />in 2011 appeared to return to normal in 2013. An analysis of the data suggests there is no adverse <br />impact of the Sanborn Creek Mine to Lower Hawk's Nest Creek. <br />10 <br />
