Environmental Protection Plan <br />Appendix T -E <br />Climax Molybdenum Company <br />Geochemical Data <br />Table T -E-3 - McNulty Overburden Storage Facility Reactor Data <br />McNulty Overburden Storage Facility (OSF) Reactor Data was obtained <br />from waste rock reactors set up on the McNulty OSF in 1998. Natural <br />precipitation was sampled as it percolated through the reactors over time. <br />Nine reactors were set up, each composed of a 100 gallon HDPE tank with <br />a conical bottom, containing approximately 1,000 pounds of waste rock. <br />Samples were taken periodically between 1998 and 2000. <br />1 of 3 July 2011 <br />Sample ID <br />Matrix <br />Lab ID <br />Date Sampled
