I think they added to their hedge after the end of Jan. Either that or they are overstating the percentage hedged in figure 11 by about 10% to be conservative (i can only hope). From the last quarterly:
55500oz hedged in FY2020 is only 88% of the expected 63koz production for the rest of year.74106oz hedged in FY2021 is only 90% of the expected 120oz production.
Also note Mar 2020 quarter only had 22koz hedged as at 31 Jan but is expected to produce 30koz. So they might be selling 8koz at a good margin for this quarter at least. Next quarter will be tragic though.
