I can only assume the news was not as positive as many had hoped. Not enough indicated resources ... too many inferred. That is only a guess on my part. A lot of selling now is due to the 'herd instinct'.
I still see this story as positive and getting better. I do have some dry powder in reserve, and am waiting to take on more shares once I get a sense of how far we might drop today.
Most of the drills are working on 50m infill, which will move a lot of ounces to indicated. There will also be expansion to the North. This stock has always been quite volatile, but it does provide opportunties to take up new positions ... like today.
