Security - Reverse Circulation and Core Samples Clause Samples

Security - Reverse Circulation and Core Samples. Crated samples are delivered to the analytical laboratory in the numbered bags, along with a transmittal sheet stating whether the samples are “cuttings” or “core”, the range of sample numbers, and the total sample count. The lab has no knowledge of the spatial reference of the individual samples, beyond being able to figure out that sequential numbers from a drill hole represent top-to-bottom sampling. In the case of cuttings, they can also infer that the sample intervals are 5 feet long (standard in Nevada). In the case of core, it will be obvious from the volume that the maximum sample length would be 6 feet, but there would be no way of identifying any interval, and many such core samples will have a variety of lengths, ranging from 1 foot to 6 feet. In addition, because of Atna’s insertion of blanks and standards in the sample stream, the lab cannot know with certainty exactly what footage a particular sample represents. Although forewarned that duplicates are present, the lab does not know where they occur in the group. By inspection of the submitted sample bag, the lab will be able to identify the blanks (red landscaping stone) and standards (pulp powder in Kraft envelopes), and will know that they occur in sample numbers divisible by 5, but will have no idea of the accepted value of each.
