RE: Leverage to silveri stand to be corrected yet i believe his point is this:
if you had a cost of production of $1. and silver was $1.10 you make 10cents or 10% 'profit'
if silver increases to $1.20 then you make 20cents, YET you have effectively doubled your profit (thus more leverage - ie 100% increase in 'profit')
VS the company with a cost of production of 10 cents that was already making $1.00 'profit' at the same $1.10 silver and ONLY makes an additional 10% on the move from $1.00 profit to $1.10 profit
feel free to enlighten me if i am off here
