While roughly 100 tons of ore from mining shipped from Sliscovich in 1914 and 1915 contained about 35 percent antimony, the value of the gold and silver in this ore outweighed the critical mineral. "Antimony is often a high-level indicator of deeper gold deposits," said Barker.

Natural antimony consists of a mixture of two stable isotopes that have atomic weights 121 (57.25 percent by weight) and 123 (42.75 percent by weight); in addition, about three dozen radioactive isotopes are known. Antimony's average concentration in the Earth's crust is 0.20 gram per metric ton (g/t).
