The mineral industry is still not a nationally managed industry by the Government of Indonesia, even though the economic potential and workforce are very large. Realizing this, KALLA then established PT. Bumi Mineral Sulawesi as a form of contribution to the National economy.

PT. Bumi Mineral Sulawesi is engaged in the Mineral processing project (SMELTER) with the final product in the form of ferronickel with a capacity of 33,000 tons/year and stainless steel. Currently, the management location is in Bua District, Kab. Luwu, South Sulawesi.
