You realize this doesn't actually work, right?

If it did, mining companies would be out of business almost instantly - their product being only useful in the market when it's worthless.

Futures contracts involve actual carrying costs - storage, transporation, delivery - with real physical goods; even if you personally aren't involved in the physical aspect (by trading derivatives or the like) someone else (e.g. the people with actual silver demand for their companies) is, and they'll make sure you can't just drive the price of silver up higher by cornering the physical market.
