Those 5 sellers building up at 23c could have bought the stock for 4c 12 months ago and paid only $3000. each.
The sellers are not massive and are probably the gold bugs that bought 2K - 5K 12 months ago.
They are selling out as 5 Baggers and are very happy with their profit. Probably 20-30% of stock holders left are in it for the gold not the Uranium.
