AISC, All in sustaining cost, is a financial metric adopted by gold, silver, and other precious metal mining companies to report their costs related to sustaining the production level of materials.
Key components of the metric include
- On site mining costs
- On site general and admin costs
- Taxes like royalties or production
- Permits, community costs, reclamation/remediation costs
- Sustaining costs for exploration and studies
AIC, All in costs includes those costs but adds in additional costs for growth. For example exploration projects to increase production or capex to provide better benefits for workers. Any any financing costs like interest.
