Overview
- Rescuers are laying a three‑kilometre power line to run high‑capacity pumps, and managers say draining and clearing could take several more days before crews can enter safely.
- Specialists report the five‑meter concrete plug is roughly 50% complete and designed to hold full water pressure, with cleaning finished and concrete injection underway under CFE oversight.
- Crews have removed about 129–130 meters of tailings and advanced an exploratory bore, and an alternate entrance identified by the operator could shorten the route by roughly one kilometre.
- The operation follows the March 25 collapse of a tailings dam and liner rupture that sent water and fine mine waste into the tunnels, where one worker was rescued and three remain trapped.
- About 300 responders work in rotating shifts as officials brief families, and canine checks found no personal gear swept away, which authorities say reduces concern the miners were carried off by the surge.
