Burned Green Rocks and a Child's Bones Reveal a 6,000-Year-Old Copper Mining Camp High in the Pyrenees

Archaeologists have uncovered evidence of a prehistoric copper mining camp in a cave at 2,235 meters above sea level in the Spanish Pyrenees, dating back to 5000 BC. Nearly 200 fragments of malachite and 23 ancient hearths were found alongside human remains including a child's finger bone and tooth. The site, published in Frontiers in Environmental Archaeology on June 3, 2026, shows the cave was used intensively during Europe's Copper Age from around 3600 to 2400 BC.
