The deal grants Teck’s subsidiary Teck Chile options to earn up to a 75% interest in Loreto by providing Golden Rim with $600,000 in staged cash payments. The Vancouver-based miner will also have to spend $17 million on exploration.
“Golden Rim believes that Loreto could well represent the last unexplored outcropping Oligocene-Eocene porphyry system in northern Chile,” managing director Craig Mackay said in the statement.
The company noted that mineral concessions at its adjacent Paguanta project are not included in the agreement, adding it was pursuing an alternative deal for the asset.
Teck is currently expanding its Quebrada Blanca mine in Chile. The project, dubbed Quebrada Blanca Phase 2 (QB2), is slated to begin operations in the second half of the year, doubling the company’s copper production by 2023.
The company recently flagged costs at the almost-finished expansion could rise by up to $500 million to between $900 million and $1.1 billion.
The project will allow Teck to extend the aging mine’s life by 28 years and substantially boost production to 300,000 tonnes of copper a year from 23,400 tonnes in 2017.
The mining giant is already studying a Phase 3, which will double Quebrada Blanca’s capacity to 600,000 tonnes of copper a year. The potential extension will make the mine Chile’s second-largest copper operation, after Escondida. It will also situate it among the world’s top five copper mines.
