Where did you get the $48M figure come from? - according to the half year report they had $33M at the end of December.
Don't believe the 58 BTT implants either - according to the April update they had done 47 BTT implants as at 31st March meaning 31 have been done in the last 3 months - you would think for that sort of money they would be able to get someone who could handle basic mathematics.
