Coeur’s addition to the S&P MidCap 400 Index reflects the Company’s growth and transformation into the sector’s only all-North American senior precious metals producer and a leading global silver company following two recent successful acquisitions, and its commitment to portfolio development through investments in exploration and mine expansions.
