Ancient Cave in Pyrenees Reveals 5,500-Year-Old Evidence of Copper Mining Industry

Archaeologists have uncovered a trove of artifacts and evidence within a remote cave nestled over 7,300 feet above sea level in the Pyrenees mountains. The findings suggest that this site was repeatedly visited by ancient Europeans for more than two millennia, challenging previous assumptions about high-mountain environments being marginal to human activity. Among the discoveries are numerous hearths containing fragments of green minerals, which researchers believe indicate the presence of an early copper mining industry.

Professor Carlos Tornero from the Catalan Institute of Human Paleoecology and Social Evolution led the excavation team that uncovered these artifacts. The cave, now known as Cave 338, contains a rich archaeological sequence spanning thousands of years. Initial excavations revealed evidence of human activity in four distinct layers, with the most significant findings located within layers two and three. These layers include nearly two dozen hearths filled with burned fragments believed to be malachite, a green mineral often associated with copper deposits.

The repeated use of Cave 338 over such an extensive period suggests that it played a crucial role in prehistoric mining activities. This discovery could alter our understanding of how ancient Europeans utilized mountain landscapes and highlights the importance of high-altitude regions in early metallurgical practices. The presence of malachite fragments, along with other green mineral remnants, provides compelling evidence for copper extraction and processing at this remote site.
