Overview
- The collapse occurred Friday before 5 p.m. in an underground gallery where six to eight meters of sandstone roof fell in a roughly 70-meter section.
- The two workers killed were identified as Oscar Diaz, 32, and Anilso Soares, 42, while a third worker narrowly escaped, according to colleagues.
- Inspectors from the regional mining service had examined the exact area the previous day and detected no risk, and authorities describe the event as sudden and fortuitous.
- The Principality launched a mining authority probe parallel to the Guardia Civil’s judicial investigation, and the Mining Safety Commission has been called to meet on Wednesday.
- Operator Tyc Narcea holds a valid research extraction permit and is seeking a full exploitation permit, has been subject to regular inspections, and says it is devastated and cooperating fully.
