Comparable-company framework
Gold miner AISC comparison—with definitions attached
Compare all-in sustaining cost disclosures only after aligning co-product treatment, attributable output, currency, period, and company methodology.
What changed
The comparison schema now records reported AISC, by-product credits, attributable production, sustaining capital, reporting currency, period, and filing page for each observation.
Why it matters
Two miners can report different AISC despite similar mines because portfolio mix, co-product accounting, sustaining-capital timing, and attributable ownership differ.
- Read the reconciliation.
- Compare the same period and currency.
- Separate company-wide and mine-level metrics.
- Keep guidance distinct from actual results.
Historical context
AISC was developed to provide more context than cash cost, but it still excludes items that can matter to equity value, including some growth capital, financing, taxes, and acquisition costs.
What could change the conclusion
Acquisitions, mine sequencing, stripping campaigns, foreign exchange, grades, recoveries, and by-product prices can change comparability from one quarter to the next.
Reproducible by design
Methodology and limitations
- Extract only issuer-reported figures and the adjacent definition.
- Convert currency only with a documented average rate and retain the reported value.
- Never mix guidance midpoint with actual AISC in the same ranking.
