Samples of pit excavation material were tested for Nb, P2O5, Zr, and Zn using X-ray fluorescence and for La via atomic emission spectroscopy. Hard rock samples were analyzed for Nb and Ta using X-ray fluorescence, for Sn using activation analysis, for Au and Ag using inductively coupled plasma analysis, for Ce, La, and Y using atomic emission spectroscopy. Selected regolith samples were analyzed for a suite of elements using atomic emission spectroscopy.
