DIGEST No. 31 (Indonesian news with comment)
Title: After Busang, Batu Hijau Date: 28 April, 1997
Indonesia's location on the volcanic Ring of Fire means it is blessed, or cursed, with a large number of porphyry copper deposits. Though an economic blessing, they are an environmental calamity. The extremely low grade of their ore means dumping tens of thousands of tons of tailings into the environment every single day throughout the decades of a mine's life. Most such mines would fail to satisfy environmental regulations in the West.
If Busang (Kalimantan) indeed contains much less copper and gold than was touted, the next largest in Indonesia after Freeport (Irian Jaya) will be Batu Hijau. Why has this deposit in Sumbawa attracted almost no media attention?
Some figures. At 15 million ounces of gold, Batu Hijau may fall well below Freeport's 80 million ounces, but it is still nearly three times larger than Kelian (East Kalimantan), the largest of another half a dozen other sizeable deposits scattered around the country. Batu Hijau was discovered in 1990 by Newmont of the US. It is now owned 45% by Newmont, 35% by the Japanese trading company Sumitomo Corp, and 20% by the private Indonesian company Pukuafu Indah. Late last year the US power and energy company Fluor Daniel landed a contract for the bulk of the US$1.6 billion construction costs at Batu Hijau. The mine will start production in 2000. Besides the gold, it contains 5 million tons of copper. Each year, it will produce almost a quarter of a million tons of copper, and half a million ounces of gold. Five thousand will be employed during construction, 2000 during production.
Now the environmental side. Its reserves may not match Freeport's, but Batu Hijau's environmental impact should easily match it. In all, 2.6 billion tons of material will be removed from the 500 m hills that make up the Batu Hijau deposit in West Sumbawa. After 20 years there will be a crater 2.2 km across, with its floor 300 metres below sea level.
Overburden, to be left to one side, makes up 1.6 billion tons of that. The remaining 1 billion tons will be processed. The vast bulk of this will becomes waste tailings, produced initially at a rate of 120 000 tons a day (similar to Freeport's today), rising to 160 000 tons a day.
Where will these mind-boggling amounts of tailings go? Simple - into the ocean. Fluor Daniel will construct a pipeline 13 km from the mine site to the beach, and then another out into the Indian Ocean for 3.2 km. At a depth of 100 m it will disgorge the entire muddy amount onto the sea floor.
It's cheap. Newmont says its production costs will be among the lowest 25% in the world. But environmentalists will want to check Newmont claims that from there the underwater mountain of tailings will slide harmlessly into an oceanic trench 3400 m deep to the south. There are international conventions about dumping wastes at sea.
Other questions also deserve an airing. We have not yet heard the views of locals about the project. Sumbawa Besar is by no means sparsely populated.
Nor have we heard what Indonesian commentators think about the composition of the mine's ownership, which excludes state participation. Both Newmont and Sumitomo are new to Indonesia. Newmont opened another porphyry copper mine, in Minahasa, early last year. This is Sumitomo's first venture into mining. Sumitomo Corp was badly hit by a copper trading scandal last year, and may sell some of its share to subsidiary Sumitomo Metal.
Indonesian partner Pukuafu Indah, according to the tabloid Kontan, is owned by flamboyant businessman Yusuf Merukh. Merukh is also a partner in Busang. He is a leader in the East Java branch of the small political party PDI, and hit headlines in recent years over his support for attempts to remove Megawati from the leadership of the party.
