Amerigo (TSX: ARG) has extended the repayment deadline for the outstanding US$56.25 million of a $99.7 million expansion facility from the end of next year to September 2023. The company can repay all or part of the four-year Scotiabank Chile and Export Development Canada term loan early without penalty.

First payment is due under the restructured loan next March.

Rob Henderson, Amerigo president and CEO, said the refinancing "substantially" reduced liquidity exposure for the company while adding repayment flexibility.

Amerigo retreats tailings from the massive El Teniente mine under a long-term agreement with Codelco.

The company's share price has dipped more than 19% since the start of the year on weaker copper prices which have impacted its profits from the expanded MVC operation.
