A representative sample was collected from mine rock stockpiled at the bench near Mayday No. 1 portal to characterize and to evaluate the extent to which the sulfidic material and metals may leach to the environment. 1.0 Mine Rock Sampling and Analyses 1.1 Sampling A mine rock pile consisting of various materials derived from the May Day No. 1 Portal was located approximately 10 feet west of the mine portal entrance. The location and layout of the pile are shown in Plate 1. The mine rock pile was of approximate dimensions 25 feet long by 13 feet wide. The peak of the pile was approximately 8 feet high, forming a rectangular conical structure. The volume of mine material was estimated at approximately 150 cubic feet. One - gallon bucket samples were collected at five locations as shown in Plate 1. A composite sample was prepared by placing the samples onto plastic sheeting and thoroughly mixing (Plate 2). The subset of the composite sample was placed in a 5- gallon bucket and transported under chain of custody to Green Analytical Laboratories in Durango, Colorado for analysis. 1.2 Analysis p 2INCORPORATED x.
