A $2.51, 7.86%, drop in the price of silver over the past 30 days and a breakthrough below $30/oz might, just might, have had a small impact - might be headed to July 2012 price of $27/oz, or less.
Don't see any technical reason for it not to continue to decline.
A $2.51 drop with a projected 2.5 million ounces produced is about $6.3 million of "lost" revenue. A $100/oz drop in gold from $1,600 to $1,500/oz on 20,000 oz is another $2 million for a total of $8.3 million.
The reality of a drop in precious metal prices for 2013 will test the "metal" of this management to realize projected cost savings, to increase production in order to offset the revenue "lost".
