Despite abundant copper deposits, the deep history of copper mining in Iberia has not been as extensively studied as in other European ore-rich areas. Here, the authors present new radiocarbon dates that demonstrate Late Bronze Age copper mining at Las Minillas, near Granja de Torrehermosa (southern Spain). Extensive mining infrastructure and abundant stone tools further identify Las Minillas as one of the largest Late Bronze Age copper-mining complex securely dated in Spain. The authors argue for a re-evaluation of links between southern Iberia and other European copper-producing and consuming regions, highlighting its potential as a major Late Bronze Age copper-producing hub.
Organic materials are rare but important components of the archaeological record. Here, the authors analyse textile residues adhering to artefacts excavated at Sanxingdui in Sichuan Province, China, a site associated with the ancient Shu culture. Through combined consideration of fibre characteristics, colouring practices, weaving structures and excavation contexts, the authors argue that, by the Late Shang period (1300–1046 BC), silk was in large-scale use at the site and, together with bronze, jade and ivory artefacts, was an important component of the Sanxingdui sacrificial system. The findings help situate ancient Shu within the broader trajectory of early Chinese silk traditions.
