Mount Fubilan was a mountain in Papua New Guinea. It is the site of the Ok Tedi Mine which has reduced the mountain to a pit in the ground. The copper mining potential of Mount Fubilan was discovered by Kennecott Copper Corporation in 1968. After feasibility studies for an open pit operation by a consortium of companies led by the Broken Hill Proprietary Company Limited, mining started in 1984 and the first copper processing facilities were commissioned in 1987.〔(【引用サイトリンク】title=TECHNICAL REPORT ON THE OK TEDI MINING LIMITED MT.
