It turns out that Javier was the only one to find any gold.  The resolution in this photo isn't enough to let you see the VERY tiny flake on the end of his thumb.  Even with the 4mb photo from an 8 megapixel camera fully zoomed in you can hardly see it.  Just thinking that the miners probably worked for months to see a flake like that would have been depressing if you were a miner.
