I asked perplexity.ai for the source of tin during the bronze age. Here was the answer.
Europe (especially Cornwall and Devon in Britain, Brittany in France, Iberia, and some Balkan regions): Recent chemical and isotopic analyses of tin ingots found at Bronze Age sites in Israel, Turkey, and Greece indicate that much of the tin originated from European deposits, especially southwestern Britain. These findings suggest extensive trade networks connecting Europe and the Eastern Mediterranean.
Central Asia (notably Afghanistan): Some scholars and ancient texts have pointed to Central Asian sources, particularly Afghanistan, as important tin suppliers, especially in the early Bronze Age. Tin from these regions likely traveled along overland routes into Mesopotamia and Anatolia.
Anatolia (Turkey): Archaeological discoveries, such as the Kestel mine in the Taurus Mountains, show that local tin mining was also practiced in Anatolia during the Bronze Age, contributing to regional supplies.
