Pan concentrate samples with the Ci prefix were analyzed for concentrations of Sn, W, Nb, and Ta using X-ray fluorescence analysis. Pan concentrate samples with the Be prefix were analyzed for Cu, Pb, Zn, Mo, and W using atomic absorption analysis and for a suite of elements using semiquantitative spectrography. Pan concentrate samples with the CP prefix were analyzed for Ag, Cu, Mo, Pb, and Zn using atomic absorption analysis and for W using colorimetry.
