BHP is a leading global diversified miner supplying iron ore, copper, oil, gas, and metallurgical coal. A 2001 dual-listed merger of BHP Limited (now BHP Ltd.) and Billiton PLC (now BHP PLC) created the present-day BHP. Shareholders in each company have equivalent economic and voting rights in BHP as a whole. Major assets include Pilbara iron ore, Queensland coking coal, Escondida copper and conventional petroleum assets, principally in Australia and the Gulf of Mexico. Onshore U.S. oil and gas assets were sold in 2018.
