This is a very difficult question to answer. Everyone has different costs. Think about it this way- if you ran a business and were in a state like California where the real estate is expensive and the government does a lot of taxing, your costs would likely be much higher than someone running the same business in, say, Wyoming.
Another factor is that more than half of all silver is mined as a byproduct of something else. In other words, they are taking zinc, lead, copper or gold out of the ground and also find some silver. Their cost for the silver is often times considered to be ZERO when this happens, and that applies to something like 60-65% of all silver mined.
Yet another factor is what is termed hedging. This is much more complicated, as you'd have to have a fairly decent understanding of options (puts and calls) to understand this. I will oversimplify- If you bought ABC stock at $16 a share (let's say that equates to $16/oz. for silver), you might not want to sell now at a loss. So, what you could do would be to sell covered calls at a $17 strike price to add some cash to your account. Let's say the options expire in 3 months and you get $1 a share cash by selling them. You then are agreeing to sell your stock (or silver in the case of the miners) at $17 s share no matter how high it goes anytime over the next 3 months until the options expire. So, if the stock stays in the $14-16 range and you never have to sell the stock, you keep the $1 per share premium as your profit.
If silver were to go to $25, you would still make a profit. Remember your cost was $16 minus the $1 premium you got, so your net cost is $15 a share. Since you are selling at $17, you have a $2 per share profit. Still, you might be disappointed that you were forced to sell for $17 when you could have gotten $25 if you never sold the covered calls.
Remember how I said that options can be complicated? This is just the tip of a huge iceberg. If it only took you 10-20 hours of study to get a good understanding of options, I'd say that would be pretty good.
So, to combine all of these factors with the notion that many companies are not totally honest about everything they know that can affect their earnings, you can understand how this could be a very complicated situation to deal with.
