Stick to the gold math bow, I said there is not enough antimony on Tesoro to talk about. What I dont know, is if there is any significant amount on the Vilcoro. All deposits are accompanied by other metals and sometimes the secondary metals are economical and help pay for mining costs.

For ex; it may cost $300 oz to mine gold on a property, but if there is a secondary metal worth bothering with, it may cut that $300 to $200, making the property more valuable.
