In Mexico, year on year in November, production rose for gold, copper, lead, and zinc, but silver production dropped 3.3%. Mexico is the worlds no. 2 producer of silver. It has been reported by all the silver experts that 70% of silver production is as a byproduct of gold, copper, lead, and zinc production. So if production of all those metals rose, howcome silver production dropped? Peak silver? http://af.reuters.com/article/metalsNews/idAFN3128824020110131.
