Ore extracted from the Agua Rica mine will be transported from the open pit by truck to the primary crusher area and then transported via a conventional conveyor to the existing Alumbrera processing plant. To route the overland conveyor system, approximately 5.2 kilometres of tunnel development will be required. The conveyor will extend 35 kilometres to the Alumbrera processing plant, where it will feed the existing stacker conveyor via a new transfer station. Annual ore feed increased to 42 million tonnes per year.

Relatively modest modifications to the circuit are needed to process the Agua Rica ore at the Alumbrera plant. The copper and by-products concentrates will be transported by the existing pipeline to Tucuman and then by rail to the port for commercialization. An in-situ blending strategy has been defined to manage the concentrate quality over certain years of the mine life, which will allow the project to achieve the desired targets. Further optimizations to this strategy are being studied as part of the current design phase.

Average annual production: 556 million pounds of copper equivalent during the first ten years.
