Description 44 samples were prepped by dry sieve -150 mesh, crush and split, ceramic pulverizing and large vial surcharge. For sulfur analysis, samples were prepped by crush and split, and ceramic pulverizing. 44 samples were analyzed by the following methods and digestions: INAA, ICP after HF-HNO3-HClO4 acid digestion with HCl leach, AA after HNO3-HCl hot extraction and DC Plasma Emission after fire assay. Samples were also analyzed using LECO Sulfur analysis.

Description 32 samples were prepped by crushing and pulverizing. 32 samples were analyzed by the following methods and digestions: titrimetric analysis and gravimetric analysis. 32 samples were analyzed for major oxides by XRF after lithium tetraborate fusion. 32 samples were analyzed for trace elements by XRF after pressed pellet preparation. Fe2O3 % is calculated.
