Extract silver from ore, win $10,000,000

Scott says:
Picture 9-12 Barrick Gold has a problem. It's got a whop of silver in Argentina, but it's tapped in silica-encapsulated ore. If you can "unlock the value" -- ie figure out a way to economically boost their current 6.7 per cent recovery rate -- they'll give you a cool $10 mil. Kinda like the X Prize, only underground.
