Perpetua Resources: A laboratory sample from Perpetua Resources was received and analyzed. Preliminary indications are that the sulfide concentrate produced by Perpetua would probably not be feasible as a source of antimony trisulfide but would be ideal feedstock for processing into antimony metal and oxide at the Company's smelter in Mexico.

Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony xide, Sb 2 O 3.
