Amerigo’s operations suffered no apparent direct damage.In normal times, Amerigo receives fresh tailings from El Teniente via a concrete channel that continues down past Amerigo
to the ultimate site of disposal. Right after the earthquake, Amerigo obliged El Teniente by excavating an emergency
channel, upstream from Amerigo’s plant, that allowed El Teniente’s tailings to decant into the Colihués tailings pond. This
halted the flow of fresh tailings to Amerigo. Meanwhile, the channel downstream from Amerigo’s plant was damaged by the
earthquake. This prohibited Amerigo from treating stored tailings, because the company would have had nowhere to put
them once it was done with them.
Amerigo reported that repairs to the channels were to have been completed last Friday or Saturday and that, as a result of
the necessity to repair the channels, it would have lost 7 to 10 days’ of full production.
On a wider scale, Amerigo noted that the tsunami consequent to the earthquake had caused more damage to Chile than had
the earthquake itself. So, for example, neither the two metallurgical plants smelters/roasters that purchase all of Amerigo’s
output, nor the roads leading to them, have been significantly affected by the earthquake. But the damage to Chile’s ports
does present the possibility that Chile’s imports of coal and oil could be hindered, with electricity prices running up in
response.
