Doesn't take much volume to move the share price when of the 213,486,376 shares outstanding 91,329,790 are owned by three entities Lewis Black, GTP, and Deutsche Rohstoff, none of who will be selling shares anytime soon and one Deutsche Rohstoff, who just did a placement for another 2,494,118.
Another 8 ish million are owned by other insiders and my assumption is these and many held by other long term holders like myself are not available for sale until at least the full value of three producing mines is reflected in the share price and more likely will be held for the dividends in the years to come.
Talk about a tightly held company!
