Ann: Gwalia Mass Extraction Feasibility Study, Guidance & webcast, page-169

Could the sharp drop be explained by a so-called "bear raid', instigated by professional shorters (SBM has been heavily shorted lately), who were in the knowing of some 'negative' information before it's release to the market? I wonder how the stock market would look like if shorting was banned (a bit less of a casino perhaps?). To me, insignificant retail investor, shorting seems like betting that an otherwise healthy horse will not reach the finish line, or to make it a bit more personal, betting that your son or daughter will have a low HSC score to avoid having to pay his/her uni fees....sorry to all shorters out there! :0
