WGR <br /> WESTERN GEOLOGIC RESOURCES INC. <br /> STANDARD OPERATING PROCEDURES <br /> RE: STOCKPILE SOIL SAMPLING <br /> SOP 5 <br /> Soil samples collected from soil piles are collected in thin-walled brass tubes 4-in long by 2-19 <br /> outside diameter. The sampling protocol for stockpile sampling are determined by the dimensions of the <br /> soil pile. An average of one soil sample per ten cubic.yards is collected. Prior to-chemical analysis <br /> samples are composited: The number of samples in composite are dependent upon the amount of cubic <br /> yards of soil. Typically,composites are made up of minimum of two samples and range up to a maximum <br /> of four samples. <br /> The sampling tools used are hand driven sampling,devices that maintain the physical integrity of <br /> the samples by minimizing volatilization. Upon removal from the sampling device the tubes are <br /> immediately trimmed and scaled with aluminum foil and plastic end caps. They are then hermetically <br /> sealed with duct tape,labeled and refrigerated until delivery-to the laboratory under chain-of-custody. <br />
