I certainly don't see anything sinister about the trading lately. This is just the way things go with a very illiquid stock. Someone wants out and it puts pressure on the sp. I certainly can't see anything negative about the drill results, just the opposite in fact and would be surprised if they prompted a sell, More likely profit or loss taking or rebalancing of portfolios.
The positive side of recent trading is that despite Ochre selling their 8.8mill shares for their own reasons, the slack was taken up by others in the top 20 over the last two months. Perth Select +3m, HSBC +5.2m and JP Morgan 3.2m etc. The top 20 held 293.8m shares at the end of March and 293.3 at the end of May. So the other major shareholders were quite willing to take Ochres' 8.8m shares off their hands. That, to me, is very positive and a show of confidence.
