Chinese Plan

AO-ZHONG INTERNATIONAL MINERAL RESOURCES PTY LTD has sold 522272 shares since the last Top 20 update. Now i believe these where the shares sold 1min before close of trade again at 18cents. Then followed up with the 1m sell order in market. Which still sits there today
The previous sell was late friday when TNG share price was starting to look good again and was 17cents and a late friday sell down happened and brought the stock to 15cents
And finally there was the big sell down, where they sold right before the close around 27-29 cents and then followed it up ruthlessly the following day.
They seem to me not wanting to sell all there shares but to keep a lid on TNG from going up or succeeding. For what reason i don't know. But there is a pattern emerging. Why always the late sell? Because that causes max share price slide without giving away to many shares.
