* Based on USGS estimates of synthetic manganese dioxide (assuming 57 percent average manganese content) and natural manganese dioxide (assuming 49 percent average manganese content).
** Data source of Indium Corporation includes in this estimate both primary/virgin and reclaimed sources of indium.
** Data source of USGS includes in this estimate primary/virgin and refined gallium, but not secondary supply because secondary supply of gallium is difficult to ascertain.
2015 figures represent the potential supply for each of these elements.
