Episode notes
Staged Open Pit Then Block Cave Plan
- Aldebaran's PEA favors a low-capex, long-life plan combining a 9-year open pit then block-cave underground lifts.
- This staged approach uses early pit cashflow to fund underground development and preserves buyer interest by keeping upfront costs lower.
Keep Options Open To Maximize Suitors
- Preserve optionality to attract many potential acquirers rather than designing a single mega-solution that narrows interest.
- Keep front-end capex modest and the footprint small to speed permitting and capture market windows when investment climate is favorable.
Designing A Study To Attract Majors
- The PEA prioritized making Altar a multi-generational, 100,000 tpa copper-equivalent project while keeping capex and permitting footprint manageable.
- SRK recommended benchmarking against actual operations to reflect current cost volatility and make the study credible to majors.
