||Rock samples were processed by ALS Geochemistry using their PREP-31 package. The samples were crushed to greater than 70 percent passing through a 2 mm mesh, and a 250-g split was pulverized to greater than 85 percent of the material being less than 75 microns in diameter. Prior to crushing, samples for whole-rock analysis were trimmed by DGGS staff to remove weathering, and cut surfaces were sanded to remove any saw metal. For whole-rock geochemistry samples, major and minor oxides were analyzed by lithium fusion digestion and ICP-AES (ALS Geochemistry method ME-ICP06). Trace elements, including rare-earth elements, were determined using lithium borate fusion digestion and ICP-MS (ALS Geochemistry method ME-MS81). Ag, Cd, Co, Cu, Li, Mo, Ni, Pb, Sc, and Zn were determined by four-acid digestion and ICP-AES (ALS Geochemistry method ME-4ACD81); and As, Bi, Hg, In, Re, Sb, Se, Te, and Tl were determined by aqua regia digestion followed by ICP-MS (ALS Geochemistry method ME-MS42). Total C and S were analyzed by Leco furnace (ALS Geochemistry methods C-IR07 and S-IR08, respectively). Au values for Whittier and Turnagain Arm samples were determined using flux digestion and fire assay and ICP-AES (ALS Geochemistry method Au-ICP21). Platinum, palladium, and gold values for the sample collected at the base of Panorama Mountain were analyzed by 30-g fire assay with ICP-MS finish (ALS Geochemistry method PGM-MS23).
