With gold prices skyrocketing and demand for other minerals on the rise, mining poses a growing threat to communities and ecosystems around the world. Conducting geospatial analysis of the Amazon biogeographic region, this report estimates, for the first time, the full extent of legal, large-scale mining concessions and illegal mining operations on Indigenous territories within the rainforest. It finds that, together, legal and illegal mining now cover more than 20% of Indigenous lands, endangering hundreds of Indigenous communities and critical ecosystems across 450,000 square kilometers.
