The Nickel Heart of Sulawesi: Introduction

In 1901, a Dutch missionary named Albert Kruyt was walking the hills south of Lake Matano in central Sulawesi when he noticed something unusual in the reddish earth. Kruyt was an ethnographer by training, a man more interested in languages and rituals than rocks, but even an amateur mineralogist could recognize what the laterite soils of the Verbeek Mountains contained: nickel, and a great deal of it. His report traveled slowly back through colonial channels, drawing little immediate attention. It would take three-quarters of a century before anyone figured out how to profitably extract what Kruyt had found. When they did, the consequences would ripple across the island and into the global economy.

After Kruyt's discovery, Dutch mining engineer Eduard C. Abendanon confirmed the deposit in 1915, but the remoteness of the site and the challenges of lateritic nickel processing kept the ore in the ground. In 1934, a Canadian Inco geologist named H. R. 'Flat' Elves hiked into th...

The scale of the Sorowako mine is difficult to grasp without numbers. As of 2023, the operation holds proven and probable reserves of 107 million tonnes of ore grading 1.70% nickel, containing 1.81 million tonnes of nickel metal. Annual ore production in 2023 reached 13.5 million...

Nickel is essential to the batteries that power electric vehicles -- a fact that has placed Sorowako at the center of Indonesia's ambitions to dominate the global EV supply chain. But the environmental ledger is sobering. An analysis by the NGO Mighty Earth ranked PT Vale Indones...

Ownership of the mine reads like a genealogy of global mining capital. Canadian Inco built and operated it for decades. In 2006, Brazilian giant Vale S.A. acquired Inco, and PT Inco was reorganized as PT Vale Indonesia. Japanese partners Sumitomo Metal Mining have held a signific...

The Nickel Heart of Sulawesi: What Kruyt Saw

Albert Kruyt spent most of his career among the Toraja and the peoples of central Sulawesi, recording their languages, customs, and belief systems before they were altered by colonialism and conversion. He could not have imagined that his casual mineral observation would transfor...
