Manado, Indonesia—An illegal gold mining shaft structurally failed and caved in during a period of torrential rain on Tuesday, trapping and killing three informal miners deep underground in a remote sector of North Sulawesi. The makeshift extraction tunnel, dug without engineering oversight into a steep hillside, succumbed to water saturation that compromised the primitive timber shoring. Fellow miners attempted a rescue using hand tools but were forced back by secondary cave-ins.

Local disaster response units and police teams required four hours to reach the remote mountainous site due to mudslides blocking the main access tracks. By the time professional rescuers cleared the debris from the primary shaft entrance, oxygen monitors indicated lethal levels of carbon monoxide inside the pocket. Recovery teams retrieved the bodies of the three victims late Tuesday afternoon.

The deceased were identified as local villagers who regularly worked the unlicensed site to supplement their agricultural income during the dry-crop season. Unregulated gold extraction operations have expanded significantly across the province as international commodity prices reach record highs. Most of these sites utilize primitive methods, relying on makeshift wooden ladders and hand-cranked winches to lower workers into narrow vertical pits.

Local police confirmed the site was operating within a protected production forest area where all mining activities are explicitly prohibited by law. Authorities have repeatedly issued warnings to the operators of these illegal concessions, but enforcement is undermined by the remote geography and shifting encampments.

Environmental agency officials noted that the heavy rain loosened the topsoil on the cleared hillsides, creating a high risk of systemic slope failure. The water entered the unlined shafts from above, eroding the clay walls until the entire overhead structure dropped into the working chamber.

The bodies of the miners were transported to a regional health center for identification and post-mortem examinations before being handed over to their families. Local village elders expressed frustration over the lack of economic alternatives that drives young men into hazardous, unregulated underground labor.

Regional police commanders announced a comprehensive investigation into the ownership of the illegal mine site, pledging to arrest the financiers who supply the equipment and buy the raw gold. Past crackdowns have rarely resulted in long-term closures, as operations quickly relocate to adjacent valleys once security personnel depart.

Engineers from the provincial mining department arrived at the scene to assess the stability of neighboring tunnels, which remain at risk of immediate collapse due to ongoing rainfall. Police have erected warning tape around the perimeter of the hillside and seized diesel generators and water pumps left behind by fleeing workers.

The regional government issued a formal directive ordering the immediate suspension of all traditional mining activities in the district until safety inspections can be conducted. Pumping equipment continues to drain water from the main breach while police guards remain posted at the trail entrance.
