@Bebeto The November RNS you are referring to was from Nov-2021 and stated:
§ Gold sales of 569 ounces ('oz') achieved in September 2021, a 7.6% and 20.0% increase on gold sales recorded in August and July 2021, respectively.
§ Operating costs of US$985/oz were achieved in September 2021.
§ Total costs of US$1,694/oz were reported in September 2021. This includes the all-in sustaining costs and also the planned capital expenditures at the Company's underground mining operations and gold processing plant and acquisition of new equipment, purchase of increased stores and mine and plant consumables and exploration equipment. During this phase of replenishment, optimisation and capital investment total costs are not considered representative of the budgeted ongoing costs of the operations, which are expected to be more representative at the end of Q4.
So let's break this down ...
> Gold sales of 569oz, no production figures so lets assume sales = production = 569ozs
> Operating Costs = $985/oz for Sept-21 which was Plant 1&2 only as no heap leach was been built until Mar-22
> Total costs were $1,694/oz so the difference of $709/oz *569ozs = $403k as stated for Sept-21 only
However RNS goes on to say that $1,694 total costs included AISC plus other costs such as:
+planned capital expenditures at the Company's underground mining operations
+gold processing plant
+acquisition of new equipment
+purchase of increased stores
+mine and plant consumables
+exploration equipment
... put another way this STATES that these additional costs were NOT part of AISC AND then goes on to confirm that "During this phase of replenishment, optimisation and capital investment total costs are not considered representative of the budgeted ongoing costs of the operations".
You could then conclude that these additional non-representative costs could be higher or lower but this is academic as they are clearly not part of AISC as per the Nov-21 RNS. Not sure how these figures could then be cast forward to infer Heap Leach costs, but happy for you to break out your assumptions and related calculations
