| Notes |
The Panguna mine was operated by BCL, majority owned by Rio Tinto, for 17 years from 1972 until 1989, when operations were suspended due to an uprising against the mine and subsequent civil war. A peace agreement was signed in 2001 and Bougainville was given greater autonomy within PNG, with a non-binding referendum in favour of independence held in 2019.
Rio Tinto transferred its 53.83 per cent majority shareholding in BCL to the ABG and the PNG Government in 2016 for no consideration, enabling ABG and PNG to hold an equal share in BCL of 36.4 per cent each. BCL is an ASX listed company with the remaining 27.2 per cent held by public and institutional investors. Rio Tinto holds no shares in BCL. |
