Quick summary: Five gold prospectors trapped for 10 days in a flooded cave in Laos have been rescued following an international operation involving divers from several countries, with the final four men walking out unaided after continuous pumping lowered the water level sufficiently. The rescue, which drew on expertise from veterans of the 2018 Thai cave rescue, has highlighted the growing dangers of informal gold mining across the Mekong basin, where economic desperation and record global gold prices are pushing rural communities into increasingly life-threatening situations. Two other villagers who entered the cave system earlier remain missing, and the rescued men may face legal consequences as Lao authorities intensify warnings against illegal mining.
Five gold prospectors who had been trapped for 10 days in a flooded cave in Laos were rescued at the weekend after a sustained international operation involving divers from several countries.
The men had entered an abandoned mine in Xaisomboun province on 20th May in search of gold ore before being cut off by flash flooding. A fellow villager who escaped in time alerted the authorities, setting off a rescue effort that drew teams from Laos, Thailand, Malaysia, Australia, France, Indonesia, and Japan.
Rescuers located five of the group in a ventilated chamber roughly 300 metres from the cave entrance on Wednesday, a week after they went in. Two other villagers who had entered the cave system earlier remain missing. Divers brought the trapped men food, water, and blankets while planning their extraction through narrow, unstable passages containing sharp rocks and sections of submerged, zero-visibility water.
Cave diving specialists Mikko Paasi, a Finnish veteran of the 2018 Tham Luang rescue in Thailand, and Thai diver Norrased Palasing arrived on 25th May and led the operation. The most difficult section was a flooded length of murky, silty water that Paasi described as resembling coffee, with passages in places barely 60 centimetres wide. None of the villagers had any prior diving experience.
Ahead of the extraction, Paasi and Palasing trained the men in how to use breathing apparatus and oxygen tanks. On Friday, the first survivor was successfully guided through the submerged section with a regulator, tethered between the two divers, in what Paasi called a “trust me dive.”
“I got him through the restrictions and everything, and he’s healthy and he’s alive,” Paasi said. “It’s not a nice place to dive. The guy was super strong.”
After the first man was brought out, rescue teams ran emergency pumping operations continuously overnight to lower the water level. The effort worked beyond expectations. On Saturday afternoon, the remaining four men walked out of the cave on their own.
“I was literally putting my wetsuit on to head in when they emerged on their own,” said Australian rescue diver Josh Richards.
Paasi said the team had joked during the operation that if the pumping succeeded, the divers might not be needed at all.
“It was the best outcome, because the pumping was always the plan, and is the safest way, where nobody’s gonna get into a risk, so we’re happy that we didn’t have to go anymore, and the pumps worked,” he said.
The Thailand Rescue Diver group confirmed the last of the five men was brought out at 15:10 local time on Saturday. Photos shared on social media showed the men on stretchers, wearing oxygen masks and wrapped in foil blankets, some with expressions of visible relief. One local involved in the rescue was searching for his own father. When the man emerged, his son Thao Oun dropped to his knees and embraced him before wiping away tears.
The damp underground conditions had taken a physical toll over ten days, with some of the men developing skin and intestinal problems. Their survival has nonetheless been described as remarkable, given the conditions they endured.
The incident has also drawn attention to the dangers of informal gold prospecting in Laos. According to the Stimson Center, a Washington-based think tank, hundreds of suspected unregulated mining sites operate across the Mekong basin outside formal oversight. In Xieng Khouang province in 2021, seven people were killed when heavy rain destabilised an illegal gold digging site and triggered a shaft collapse. Human rights groups and regional NGOs have pointed to economic desperation in rural communities, where limited wage labour and subsistence farming leave few alternatives. Record-breaking global gold prices have intensified the drive, pushing prospectors into riskier terrain during the rainy season.
Lao state media coverage of the rescue has emphasised warnings against illegal mining, raising questions about the legal consequences the rescued men may now face.
The two missing villagers are believed to have entered the cave earlier than the group that was found. Josh Richards said a significant air pocket exists roughly 100 metres further into the cave, through what he described as “a fairly lethal passage” beyond where divers have so far gone. Overnight rain has raised water levels again, complicating any further search.
“From what we know, there is a significant air pocket that is considerably further on, through fairly lethal passage,” Richards said. Paasi told CBS News that the two men were no longer believed to be alive, or may have been trapped in spaces too small for divers to enter.
