With overwhelming shareholder approval and a projected completion date in October 2025, this $1.08 billion transaction signifies a carefully calculated expansion into the copper market. This acquisition enhances Harmony's exposure to a metal that's becoming increasingly vital in the global push toward renewable energy and electrification.
