David Morgan interivew with The Daily BellHere is a reference in his interview June 21 to Azteca:
David Morgan: First it is important to mention that 70% of the silver brought to surface by mining is a result of base metal mining. And among the top ten silver producers in the world you will find companies like BHP, KGHM Polska, Goldcorp, Rio Tinto, Pan American Silver, and Industrias Peñoles. As far as primary silver companies, you can look to Pan American Silver and perhaps Hecla, Coeur, and Silver Wheaton.
For smaller companies I like the ones that have large upside, and we have several on our list. I normally do not reveal this information for free, but will mention a few here: Endeavour Silver, First Majestic, and Great Panther. We are currently looking at a company that has made a discovery of perhaps a Sullivan type, so once the analyst tour is completed later this month, we might want to visit that, if you are inclined to give me a follow-up interview.
