@Drugo, the production & cost trends for WMX convey a theme of under-performance....
FY18 :
70,565 oz @
AISC $1,629 /oz
FY19 :
65,406 oz @
AISC $1,760 /oz
FY20 :
61,885 oz @
AISC $1,950 /oz
FY21 : considering the rate of declining production & increasing AISC over the past (3) years, ongoing impact of CoVid related site restrictions, inadequate workforce, delayed access to high-grade ore & ore grade issues......I'd say your 60koz @ AISC $1950/oz is overly optimistic.
