Some of this financial uncertainty at Codelco’s operations could be explained by the miner’s recent decision to convert its Chuquicamata mine into an underground operation, a move that will require a series of changes to the mine’s assets and infrastructure, and as a result, could impact the mine’s insurance requirements.
“If you've got to go underground, it's not a cheap process,” said Neil Stewart, managing director of global and corporate property at Gallagher, who highlighted how differences between the needs of open-pit and underground operations could change the miner’s financial obligations. “That's usually more so than if you're just breaking off a bit of top soil and then you can start processing things,” he continued.
“When you go underground, you will insure things like the shaft infrastructure, the air conditioning-type infrastructure, the electricity power supply-type infrastructure, and then you'll have things like conveyors and trucks and hauls and things underground.
“Some of [the Latin American mines] are kilometres across and kilometres deep, as opposed to hundreds of meters wide and hundreds of meters deep, and over time they're susceptible to events like earthquakes and some pitfalls have collapsed. So that in itself creates operational challenges, but going underground really creates operational challenges.”
These insurance challenges are compounded by the vast scale of the new underground operations. The mine will require the construction of more than 750km of new underground tunnels up to a depth of 3km below the surface, and up to 60 blocks each measuring 35,000 square metres will be excavated using block caving techniques over the course of the mine’s life.
However, Stewart also noted that insurance projects remain broadly similar across heavy industries. Regardless of the assets involved or specific risks to workers, the overarching purpose of protecting employees and ensuring efficient operations means many mining insurance frameworks are fundamentally similar; “broadly, an underground mine is an underground mine,” he said.
