Bronze Age Interactions: The Tin Trade

[snip] archaeologists are able to cross-reference the trace elements found in artifacts with naturally occurring concentrations across the world. For example, at shipwreck near Haifa, present-day Israel, numerous tin ingots, with Minoan symbols indicating ingots are from the bronze age, had trace elements of cobalt. Archaeologists must now find a source of tin with similar traces of Cobalt to determine the origin. Yet, they have failed to find an exact match, the closest being Cornwall, present-day England, which has concentrations of cobalt and germanium. [/snip]

Bronze Age source of tin discovered [1994]
http://chronicle.uchicago.edu/940106/tin.shtml
[snip] The site of the mine, Kestel, is about 60 miles north of Tarsus. Yener’s work at the mine and at nearby Goltepe, an ancient miners’ village, provides new insights into the development of the tin industry. Perhaps most important is her discovery that tin can be smelted in crucibles at relatively low temperatures, a finding that may change established theories about economic and metallurgical developments in the Bronze Age Mediterranean world.

Enduring Mystery Solved as Tin Is Found in Turkey
https://www.nytimes.com/1994/01/04/science/enduring-mystery-solved-as-tin-is-found-in-turkey.html
[snip] The mine, at a site called Kestel, has narrow passages running more than a mile into the mountainside, with others still blocked and unexplored. The archeologists found only low-grade tin ore, presumably the remains of richer deposits that had been mined out. For this reason, Dr. James D. Muhly, a professor of ancient Middle Eastern history at the University of Pennsylvania, said he was skeptical of interpretations that Kestel was a tin mine. [/snip]
Yes, I could see how that would work if you found tin ingots.
