Marimaca Copper has chosen a preferred lender for a project finance loan of $375 million to $400 million to build its copper mine in northern Chile. Its chief executive said the copper rally is making it easier for new projects to raise money.
At a glance
- Marimaca needs about $750 million in total to build the mine.
- The open-pit mine is designed to produce about 50,000 tonnes of refined copper a year, with first output in 2029.
- The company aims to close the financing by the end of the year.
Background
Project finance is a loan repaid from a mine's future cash flow. Marimaca's project is in Chile's northern Antofagasta region, and the company is listed in Toronto and Sydney. Copper prices are near record highs as new mine supply struggles to keep pace with demand.
What happened
Marimaca Copper selected a preferred lender for a project finance loan of $375 million to $400 million, chief executive Hayden Locke said in an interview on Wednesday, Bloomberg reported via MINING.COM. He did not name the lender, which he described as a specialist mining lender.
The company weighed future supply deals and offers from commercial banks before making its choice, and aims to close the financing by the end of the year.
Why lenders are interested
"There's financing available for copper projects," said Locke, a former JPMorgan Chase banker. Inflation, higher interest rates and geopolitical tension would normally weigh on funding, he said, but demand from electrification is meeting limited supply, with few projects ready to build.
He said the lender's terms were very competitive, at or below the lower end of what Marimaca expected.
The project
Marimaca expects to need about $750 million in total for the open-pit mine in the Antofagasta region, designed to produce about 50,000 tonnes of refined copper a year. It could become larger through the nearby Pampa Medina discovery.
The company has begun infrastructure work, aims to start full construction in the second half of next year and expects first production in 2029. Its shares have lost about a third of their value this year.
