Before sunrise, boats cross the San Juan River carrying miners, fuel, radios and chemical supplies toward Crucitas, a gold-rich corner of northern Costa Rica. Costa Rican officials estimate that between 3,000 and 5,000 people are involved, while the government says roughly $252 million in gold is removed from the country each year.<\/p>\n\n\n\n

This is no longer simply a story about informal miners digging in the jungle. It has become a cross-border supply<\/a> chain with fast river access, semi-industrial processing and alleged buyers on the Nicaraguan side, all while Costa Rica absorbs the environmental damage and policing bill.<\/p>\n\n\n\n

A border built for escape<\/h2>\n\n\n\n

The geography gives the mining networks a major advantage. Costa Rican officers cannot use the river as an armed patrol route<\/a> and must approach key extraction zones over land, sometimes after a three-hour walk, while miners can retreat across the border within minutes when spotters report approaching police.<\/p>\n\n\n\n

How do authorities hold ground when the escape route is by boat and reinforcements are hours away? Officials say the networks use WhatsApp, radios and drones to monitor police movements, turning a remote forest into something closer to a coordinated logistics hub.<\/p>\n\n\n\n

Former Security Minister Mario Zamora told lawmakers that about 90% of the miners were foreign nationals, mainly Nicaraguans. Officials have put the monthly security cost at between $1 million and $1.3 million, yet the flow of people and ore continues. That is a costly stalemate.<\/p>\n\n\n\n

The forest pays<\/h2>\n\n\n\n

The damaged area has expanded from roughly 2,200 acres to more than 7,400 acres, reaching beyond the original Crucitas site into Las Conchuditas. What began largely as hand digging now includes pumps, powerful diesel generators and cyanide leaching systems that can process far more sediment.<\/p>\n\n\n\n

The result is easy to picture. Tree cover gives way to muddy pits, unstable tunnels and pools used for chemical processing, while disturbed soil can wash into streams and aquifers<\/a> after heavy rain.<\/p>\n\n\n\n

Costa Rica\u2019s Constitutional Chamber cited alleged mercury and arsenic contamination, biodiversity loss and risks to drinking water. It ordered a permanent police presence, continued potable water deliveries and a coordinated restoration plan, a clear sign that the damage is now treated as a public health issue as well as an environmental crime.<\/p>\n\n\n\n

The trail leads north<\/h2>\n\n\n\n

Costa Rican officials and the environmental group Fundaci\u00f3n del R\u00edo allege that gold-bearing sediment<\/a> crosses into Nicaragua and reaches the Las Cruces camp, near concessions held by Thomas Metal. According to those accounts, buyers weigh sacks, pay in cash and use processing methods capable of recovering far more gold than small miners can extract on their own.<\/p>\n\n\n\n

The claimed efficiency gap is striking. Officials say artisanal miners may recover 15% to 20% of the gold in sediment, while industrial techniques can reach as much as 95%, creating a strong incentive to move unprocessed material across the border.<\/p>\n\n\n\n

China\u2019s ambassador to Costa Rica rejected the allegation that Chinese companies were buying ore stolen from Crucitas and called it unverified media propaganda. That denial matters, but so does traceability, especially because researchers identify Thomas Metal as Chinese-linked and Nicaragua has expanded concessions into protected areas.<\/p>\n\n\n\n
