Most gold production officially reported in government statistics was a byproduct of Freeport Indonesia's copper mining. In 1989 total official gold production was about 6,000 kilograms, of which about 4,000 kilograms was extracted by Freeport Indonesia with a 15,000 kilogram production expected by the end of 1992. However, a large number of small-scale mining operations in Kalimantan may have produced as much as 18,000 kilograms of gold in 1989. Many of these small mines were operated illegally on foreign concessions. In 1989 there were approximately eighty foreign contractors with concessions for gold exploration, primarily in Kalimantan, but only a small number had producing mines.
