Newmont Corp's stock experienced a significant intraday plummet of 5.02%, underperforming the broader market. The sharp decline occurred during Thursday's trading session, reflecting heightened investor concerns.

The movement appears driven by a combination of operational and market factors. A primary contributor is the suspension of underground operations at Newmont's key Cadia gold and copper mine in Australia, following a 4.5 magnitude earthquake in the region. This disruption introduces uncertainty regarding production from a major asset.

Additionally, a softer trend in gold prices is pressuring near-term sentiment for gold miners. Investors are also likely positioning ahead of the company's upcoming first-quarter 2026 earnings report, with management having previously guided for lower production and higher costs for the full year.
