Proof of Hedge Funds Shorting Miners?

I understand a lot of respectable people have been throwing around the idea that hedge funds have been massively short silver miners, which is to blame for their under performance. However, I've checked out quite a few of these miner stocks, one of which (my favorite) SLW, only has a short interest that would take 1 DAY, that's one trading day, to completely cover.

Am I missing something? I have quite a bit of money in the miners, for obvious reasons, but really, I cannot seem to find any real data that backs up the myth that hedge funds are to blame for shorting the miners below real valuations...

any help?
