Check out this story filed by Associated Press on the relationship between big mining and small villages in Peru, with the massive Antamina mine as its focus. For example, this snippet about the locality that hosts Antamina, San Marcos:
The district of San Marcos, where the mine is located, is the country’s richest — receiving about $50 million a year in royalties. Yet it has no paved highways, no hospital, and no water treatment plant. Nearly one third of toddlers suffer from chronic malnutrition — double the national average.
It’s compelling reading, the story that neither the government of Peru nor the mining companies want you to read. Whole thing here, including a great photoshow.
