<br />4.0 SEEP AND SPRING INFORMATION <br />Two spring monitoring points, SP-8 and SP-9 are monitored and the results compared with <br />baseline and historic monitoring data. A significant change in the quality or quantity of flow <br />from these springs and seeps after retreat mining might indicate that the mine might be impacting <br />these water resources. <br />The data collected from Oxbow's groundwater monitoring stations, along with the results of <br />laboratory analyses are presented in Exhibit 2 -Groundwater Information <br />Spring SP-8 <br />Based on the quality and location of spring SP-8, it was determined that the source of the spring <br />was the abandoned Oliver Mine. Until 1999, flows from this spring were been relatively <br />consistent. No flows were recorded during any of the 2001, 2002 or 2003 monitoring events. <br />Based solely upon coincidence, Oxbow believes that water from the Oliver Mine may have <br />drained into the Sanborn Creek mine at the time of the 1999 mine fire event. Since this event <br />occurred, no flow from Spring 8 has been recorded. <br />Suring SP-9 <br />• Spring 9 is a seep at the base of a landslide feature in the Unnamed Gulch. Historically, flow <br />had been nearly continual, but at very low rates. The source of the spring appears to be a <br />shallow perched water zone discharging from the toe of a surface slide feature. During 2003 the <br />spring did not flow. <br />l J <br />9 <br />
