I have a few shares left and not sold because it is not worth bothering about. There was a time when this stock was over a dollar when their standard operating procedure started. It starts with a few generally promising announcements intended to say that there may be great promise here and then followed a CR. (Note how frequently they say in the announcements that nothing is promised ). This is followed by a gradual (sometimes quick) decline until they discover some new lease area and the announcement followed by CR pattern is repeated.
So predictable but all of us have to learn by their own mistakes.
However, who knows, one day they might stumble across, by mistake, something that is truly valuable. I am not punting on Lithium but who knows some rare earths would be useful.
