Be careful. They are a beneficial owner of 10,511,323 shares with the remainder being borrowed shares (shorts). From their last full disclosure (
www.asx.com.au/asxpdf/20160715/pdf/438l3b4405zktf.pdf) they were a beneficial owner of 7,793,201 shares so since the 15/07/2016 they have been net buyers of 2,718,122 shares, so not much dollar value given share price since.
Since the 27/02/2017 they have bought 1,702,198 and sold 1,399,749 for a net buy of 302,449 shares (@ 0.10c per share $30,245 - so very little value). If they've sold anything significant since 03/03/2017 they will cease to be a substantial holder in the next couple of days. This announcement is not a buy signal.
