....as suspected!
(Don, Gilder was one of AUMN's largest holders and per SEC filings they've been liquidating). They still had like 1MM + shares at the end of March.
Gilder admits on their website that they buy everything on margin and this can force liquidation:
Our firm was founded to help small investors build significant capital over time.
Since we believe in owning as many promising stocks as possible, we generally buy on margin.* Borrowing to invest can force liquidations if the market collapses, so we try to balance this exposure by selling short.

This is EXACTLY what has happened. These guys buy on behalf of small investors. With the stock markets globally getting slammed, I bet they've been dumping a lot of positions because small investors do not pony up cash when they get margin calls.
