LKA International Inc. Golden Wonder / Level 6/ Hydrologic Setting Methods A summary of the geologic formations encountered, the water levels and the well development features is provided in Table 2. • Piezometer Well C - GWPZ-C: was installed immediately down-gradient of the Historic Collapse seep in order to characterize the potential seep subsurface flows that may contact the waste rock pile. In the absence of locating seep related subsurface flows, this well would provide strategic drill profile column information for the waste rock pile immediately adjacent to the historic Deadman Gulch drainage. The piezometer well was drilled with the intent to develop the slotted portion of the well within the identified `wet zone'. Thus, the core was reviewed real-time at the time of drilling to define the depth to the water saturated formation. The core was simultaneously characterized by a geologist from Richmont Mines Inc., to identify the geologic formations encountered; and the entire core was sampled into 10'ft composite samples. The well was developed in a manner where the well would capture and contain `formation-specific' water and would not act as an integrative well where water from any formation could fill the space. The geologic log for Well C is provided in Appendix B. A summary of the geologic formations encountered, the water levels and the well development features is provided in Table 2. 2.3 SAMPLE ANALYSIS The suites of analysis for each sampling effort vary depending upon the ultimate purpose of the sample result. For instance, the historic samples gathered from Deadman Gulch, the Golden Wonder Underground Sump and the Waste Rock toe seep were initially analyzed for dissolved metals. The actual suite of metals was recommended by the DRMS at the time of the initial sampling efforts. The later samples were typically analyzed for more robust suites of analysis. At times, for specific sampling events (such as the 2007 Chemical Trace analysis) a very select list of analytes was chosen (i.e. for the Chemical Trace study, major cations and anions were chosen in order to model/graph water types). Samples from the 2008 piezometer wells, and associated sources (Deadman Gulch, Historic Collapse, Golden Wonder underground sump, Level 3 water etc.) were typically analyzed for total and dissolved metals content, as well as standard water chemistry parameters such as pH, conductivity, alkalinity etc. Solids samples were analyzed for bulk total solids metals content, SPLP metals potential, and Acid Base Accounting parameters - including forms of sulfur. Samples were transported directly to the laboratory and within the required holding time time-frame. Additional, in-field water quality measures were taken using hand-held meters that were pre- and post-calibrated. Solid samples were also analyzed for immediate paste pH measures following standard USGS guidance and techniques (USGS, 2005). 6
