Ann: Diamond Drilling Commences at Lindi Jumbo Graphite, page-56

Yep, I reckon that's what it sounds like. An investor bought in big early on, hoping the stock would keep on running due to momentum. Didn't expect that there's still a bit more time for this stock to mature (proving up by drilling for potential partner some time this month and early next month as explained by you, GB, in one of your previous FA threads by the Gant chart you posted up via the company's announcements). I reckon they needed that money back or they are a period trader that has to follow the trading rules they have established for themselves and have bailed on the first sign of good news dragging a few short term period traders along for the ride. The SP looks like it's being controlled by short-term traders at the moment rather than medium to long-term traders and potential investors. Will have to see how this stock plays out in the next couple of weeks. Interesting...
