Summary

Aldebaran Resources announced a Preliminary Economic Assessment (PEA) for its Altar copper-gold project in San Juan, Argentina, revealing robust economics with an after-tax NPV (8%) of US$2 billion and an IRR of 20.5% over a 48-year mine life. The study outlines a combined open pit and underground operation with average annual production of 101,413 tonnes copper equivalent (CuEq) and competitive C1 cash costs of $2.02/lb payable Cu. The PEA is based on an updated Mineral Resource Estimate, with approximately 80% of the mine plan resources categorized as Measured and Indicated, and also explores a Nuton Technology processing alternative.

Reasoning: The Preliminary Economic Assessment (PEA) for the Altar copper-gold project demonstrates robust economics with a high NPV and IRR, supported by a long mine life and significant production. The underlying Mineral Resource Estimate (MRE) has a high proportion of Measured and Indicated resources. While copper recovery is strong, gold and silver recoveries are low, and arsenic in concentrate presents a potential penalty risk.

Positive factors

  • High after-tax NPV (8%) of US$2 billion and IRR of 20.5% for the project
  • Long mine life of 48 years with significant average annual production of 101,413 tonnes CuEq
  • Attractive initial capital of US$1.59 billion with a NPV/Initial Capex ratio of 1.27x
  • Competitive C1 Cash Costs of $2.02/lb payable Cu LOM and AISC of $2.59/lb payable Cu LOM
  • Combined open pit and underground operation maximizes value by pulling forward higher-grade material
  • High proportion of resources (80%) in the mine plan are in Measured and Indicated categories
  • Potential for Nuton Technology to reduce LOM capital and operating costs, and eliminate tailings dam
  • Copper recovery of 87.76% for the flotation circuit is strong for a porphyry deposit

Negative factors

  • Gold recovery of 57% and silver recovery of 50% from the flotation circuit are low
  • Arsenic is present in the concentrate (0.5% to 2.2%), potentially incurring penalties
  • The PEA includes Inferred Mineral Resources, which are considered speculative
  • Nuton Technology does not recover precious metals (gold and silver)

Low confidence — this extraction should be reviewed alongside the original source.

How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
