Erich 1118111w, RE <br />ENV <br />AfAr ED <br />?qo p. <br />M?,v)4 aR <br />17 a sa '!, of "91c, off" <br />aflety n, <br />May ?y M?? ?? <br />M-19ai-l8S_ <br />The following presents the proposed sampling plan Wildcat Mining Corporation to address permit adequacy questions. <br />In addition we have attached the proposed laboratory program for water, and whole rock analysis. <br />Surface Water <br />Sample locations are presented in Exhibit E-6 (May Day) and Exhibit E-6 (Idaho). Please note that surface water <br />samples and flow quantity will be collected from all sampling sites. Included in the sampling program are two samples <br />from the La Plata River and two from Little Deadwood Gulch.. One sample from Little Deadwood Gulch will be taken <br />above the Lamb Portal and one below the May Day Level 2 permit boundary. In addition, as noted on Exhibit E-6 a <br />surface water sample will be obtained from the spring (below Idaho) that discharges to the La Plata River. A total of <br />five samples and one duplicate sample for Quality Assurance/Quality Control purposes will be collected. <br />Samples and flow data will be obtained using R2 Incorporated's Standard Operating Procedures- <br />• SOP 1 Surface Water and Seeps <br />• SOP 2 Stream Flow Measurements <br />• SOP 8 Field Equipment Calibration <br />• SOP 52 Photos <br />Samples will be field filtered in the field and sent to a certified laboratory for analysis under established sample <br />management protocols. Each sample will be analyzed for the analytes summarized in Table 1. <br />Ground Water (Deferred) <br />If needed groundwater samples will be obtained from either the underground workings or through the construction of <br />groundwater wells. The preferred method is to obtain representative samples from the underground workings. <br />Whole Rock Sample <br />Run of mine rock is currently stored on the May Day Level 2 bench. Five one pound samples will be randomly selected <br />and composited to form one sample that will be sent to the laboratory for analysis under established Chain of Custody <br />procedures. Samples will be analyzed using established laboratory protocols for: <br />• Acid-Base Accounting; <br />• Whole rock analysis; and <br />• Synthetic Precipitation Leachate Potential (SPLP) with the leachate analyzed for the same analytes <br />as Table 1. <br />`.Strategically Positioned - Technically Prepared' <br />8034 East Eastor Place, Sulte 100, Centennial, CO 80112 <br />303.8327664
