Ann: Quarterly Report Q2 FY23, page-82

To highlight how pathetically incompetent St Barbara management are; AISC $2,666/oz

Today Kingstone Resources KSN reported record gold production at Mineral Hill of 1,457 ounces. (They must be using pans down at the local creek)

• Reconciled processing recovery was also a record high of 64.8%, a significant improvement
from 41.8% one year ago.
• All-in-sustaining costs (AISC) were A$1611/oz for January and the gold price received for the
month was A$2,725/oz January

Yes this very small operation puts SBM to shame and good on them. 1,457 ounces with an AISC of $1,611/oz more than $1000/oz less than SBM can produce it for with all their experience and so called expertise. It is just pathetic.
