Just supose for a moment the mineing tax goes through in its current form.
First year companys make large profit in excess of 6%, government gets large tax payment and starts spending.
Second year companys makes 5.9% profit ,either through downturn or creative accounting.
Government gets nothing but has already spent the money.
Guess who get to make up the difference.
