Mexico’s Mercury Boom is Poisoning People and the Environment (Associated Press)

In Mexico’s Sierra Gorda mountains, soaring international gold prices also have created a mercury boom. Since 2011, mercury prices have skyrocketed from $20 per kilogram to between $240 and $350 per kilogram today. Most of Mexico’s mercury is trafficked to Colombia, Bolivia, and Peru for use in illegal Amazon gold mining operations that contaminate rivers and ecosystems.

The Mining Town Funding Congo’s Rebels and Tech Giants (Reuters)

In April 2024, the M23 rebel group seized control of Rubaya, a mining town that produces 15% of the world’s coltan—a critical mineral worth used in mobile phones, computers, and aerospace components. Rebels imposed a parallel administration in the town, and placed a 15% tax on mineral traders that generates $800,000 monthly from levies. Thousands of impoverished miners in the town, however, still work 12-hour shifts in dangerous conditions earning just $5.15 per day.
