very good copper article, page-7

papertigger - the reason i didn't think much of the article is that it didn't explain why the pig farmers might be building a private stockpile.
this article goes a little deeper but still doesn't hit any marks. those pig farmers are just as inscrutable as the rest of their countrymen.

until we get some further insight those pig farmers might as well be taxiing their charges on the runway in readiness for take off.
