Our History

Otraco was founded in 1972, by Basil Winterbourn at the Mount Newman Mining (now BHP Billiton) Mount Whaleback mine – a contract that we still have, over four decades later. 

Within a few years we had won contracts at Savage River and Goldsworthy/Shay Gap, and in 1985 added Argyle Diamonds and Koolan Island Iron Ore. 

In 1993, we won our first Hamersley Iron (now Rio Tinto) contract at Paraburdoo/Channar. This has now extended to contracts with all Rio Tinto iron ore operations in the Pilbara. 

A year later, we expanded our operations internationally, winning a contract with Rio Tinto at Kelian Gold mine in Kalimantan (Indonesian Borneo). By 1996, we were working at the largest mine in the world, BHP Billiton’s Escondida Copper mine, expanding later to Cerro Colorado and Codelco’s Radomiro Tomic operation.

In March 2006, Otraco was purchased by Downer Mining after having been in private ownership for 34 years. 

Our first contract in Southern Africa was won in 2010, at Anglo American’s Mogalakwena platinum mine. A year later, we started licensing our Otracom software overseas.

In the years following, we have increased our presence both in Australia and overseas, with over 30 contracts in Australia and a plethora of international contracts including the world’s richest diamond mine - Jwaneng in Botswana, Kumba Iron‘s Sishen mine in South Africa, and Codelco’s Ministro Hales.
