Ann: SO4 Recapitalisation process has commenced, page-44

You need to either a) sell your shares in an off market transfer, b) wait for SO4 to resume trading on the ASX (may or may not happen) and then sell them (probably close to $0) or c) wait for the Deed Administrator to provide a declaration the shares are worthless (which is unlikely to happen as it seems like SO4 still owns so tenements of questionable value).
