I wasn't watching live but saw it in the chart the next day. There was a similar jump downwards last Friday and Tuesday and Wednesday this week. With these low volumes maybe these movements are typical? Or it someone dumping a position a little bit each day? Tox Free are not so keen on putting out ASX news. I seem to get updates on the gold miners at least once a week. Maybe they could do more to get their story out?
