Selling looks WAY over the top. TIE still has plenty of exploration upside and their updated LOM and Heap Leach FS is due soonish. In the meantime, the strengthening AUD GP is helping de risk the project, (not that the SP reflects this.)
AISC or All In Sustaining Costs is not a true reflection of total costs. CAIC or Corporate All In Cost is the one you want to focus on.
The CAIC adds growth capex, corporate costs etc
TIE's feasibility study will be a fair way off as it was compiled before the worst of the inflation hit. I would add $250 USD an ounce to that AISC figure. Growth Capex shouldn't be anymore than $250 USD an ounce for the first couple of years (likely a lot less than this if mined pre stripped before production).
This is my cost worst case scenario when hitting guidance (just my guess). AISC $651 INFLATION ADD ON $250 CAIC ADD ON $250 CAIC USD $1151 Current Gold Price $1850 Margin $699
Ounces produced 260,000 x $699 Cashflow USD $181,740,000
Tax loss offsets should cover first couple of years of production. TIE will still make huge money even if one argues that the production guidance figure for CY23 will ultimately be overly optimistic.
200,000 ounces produced x $699 Margin Cashflow USD $139,800,000
