Supplementary Figure C: Mount map of 2022-IGO1, showing locations of xenotime with respect to ore mineralogy (including chalcocite). Note that not all xenotime was analyzed; the numbering system was initially chosen on low-resolution BSE images obtained with the TIMA, but high-resolution images revealed that many xenotime grains were below the analytical resolution. Two depth slices of 2022-IGO1 are shown, with the original depth also corresponding to the automated mineral analysis maps of the individual polished blocks in Supplementary Fig. A.
