Wenco will supply its fleet management system and BenchManager high-precision machine for the high-altitude project.
The BenchManager machine guidance system will be used to manage the site's excavators and drills, while a high-precision system will be used on the fleet of trucks.
Salares Norte has also purchased Wenco's ReadyLine asset health management system.
The system at Salares Norte will be connected using LTE telecommunications technology.
"Salares Norte is an exciting opportunity for us," said Wenco regional manager for Latin America, José Eugenio Saravia.
"Gold Fields is one of the largest gold mining companies in the world and we already have a strong relationship with them through the St Ives project in Australia. The recent successes we've had throughout Latin America — from Mexico through to Argentina — really shows the expansion of Wenco's capabilities in the region in just the past few years," he added.
The Salares Norte project is located in the Atacama region of northern Chile at altitudes of up to 4,900m above sea level. A maiden mineral reserve of 3.5Moz of gold and 39Moz of silver was declared in December 2018. The gold-equivalent Mineral Reserve is 4.0Moz.
