Shares in Hochschild Mining (LON: HOC) fell nearly 22% on Tuesday, their steepest drop since November 2021, after it announced a six-week halt of processing operations at its Mara Rosa gold mine in Brazil due to heavy seasonal rainfall.

The South America-focused precious metals miner is suspending activities at the mine’s processing plant carry out maintenance and repair work on the tailings filtering system, which has been affected by rain and contractor-related issues. Mining operations will continue during the shutdown, Hochschild noted.

Mara Rosa, which began commercial production in early 2024, yielded just over 25,000 ounces of gold between January and May, well short of pace to meet its guidance of 94,000 to 104,000 ounces of gold this year.

That forecast will now be “significantly reduced,” the company said, adding the production shortfall will impact operational costs.

Chief executive Eduardo Landin will oversee a full review of mining, processing, and waste management activities at the site in an effort to identify bottlenecks and stabilise output.

Berenberg analysts, who had previously expressed caution about the mine’s first wet season, now expect production to fall to about 74,000 ounces, roughly 20% below the original target. They estimate the downgrade will hit group earnings per share by about 10%.

“The challenges at Mara Rosa have gone beyond weather-related delays and now include serious issues with the tailings filtering process,” Berenberg noted. “It remains to be seen how effectively operations can be steered back onto the right track in the near term.”

By early afternoon in London, Hochschild shares were still trading down at 234p, valuing the company at £1.22 billion ($1.7 billion). 

Mara Rosa, located in Goiás state, is Hochschild’s first operation in Brazil, where it is expanding its footprint. Last year, the miner acquired the Monte Do Carmo project for $60 million.

Other than in Brazil, Hochschild has mines in Peru and Argentina and is advancing development projects in Chile and Peru.
