Overview
- Four workers remain underground after Wednesday's tailings-dam breach at the Santa Fe mine in El Rosario, where 21 of 25 on shift got out.
- A unified command said Sunday it now has about 300 specialists and 42 vehicles on site, working in rotating teams around the clock to reach them.
- Teams are working near 300 meters on mud‑clogged ramps, adding wood supports and a cement mix now, with resin due Monday, to stabilize a safe path.
- Officials say the men are alive and receiving water and oxygen, with three believed to be near 350 meters and one near 100 meters as extraction plans continue.
- Preliminary checks point to a liner failure in the tailings dam that let waste seep into tunnels, and the incident was reported to authorities a day after it happened.
