Well, metallurgy did arrive to the Finns with Indo-Europeans...In any case, Basque as we see it today is effectively a language of the iron age, and it's basically impossible to tell if the many later terms (agricultural terms, word for 'horse', words for metals) are foreign terms or common terms of whatever language family Basque belonged to. But in any case I think the case is very compelling that the Basque language was at it's location since at least the Neolithic, and also that I2a1 is probably the 'original' Y-Haplogroup of the Basques.
What is interesting is that for a comparison, the Finnic languages adopted a lot of terms from Proto-Indo-European (or IE close to it), including metal words. Most peculiar, the Finnic word for 'iron' is a cognate with the Balto-Slavic word for 'ore', which is in turn a cognate with the word for 'red' in most other branches of Indo-European.
I remember reading once that the Basque words for knife and axe may come from the same root as the word stone, though.
