Its not a Tier 1 mine as it isnt built. Cascabel is also not a Tier 1 mine as it isnt built yet!
If you use the same metrics as you want to use for Cascabel ie todays Spot Prices it is a Tier 1 mine by anyone's definition.
i dont know which AI you are using but ive just used the paid Chatgpt and the google one and both say it is a Tier 1 mine.
Here is chatgpt
Is Cangrejos a tier 1 mine
ChatGPT said:
Here’s the most clear and balanced answer to “Is Cangrejos a Tier 1 mine?” — based on its data and the industry’s accepted definition of Tier 1.
📋 What defines a Tier 1 mine?
A Tier 1 mine is typically:
✅ Very large — long life (>20 yrs) and high annual production (>500 koz AuEq or >500 Mlbs Cu)
✅ Low cost — bottom half of the cost curve, robust even at low metal prices
✅ Low risk — politically stable, low jurisdictional risk, strong social licence
✅ Proven — consistent production & financial performance over time
🔷 Cangrejos Project (Lumina Gold, PFS 2023)
Metric Value
Mine life ~26 years
Reserves 11.6 Moz Au + 1.4 Blbs Cu
Annual production (avg) ~371 koz Au + ~44 Mlbs Cu
AISC ~$1,000–1,100/oz
Jurisdiction Ecuador (moderate risk)
Status PFS stage — not yet built
🧭 So — does it meet Tier 1 criteria?
✅ Scale & longevity: Yes — its reserves and 26‑year life clearly meet Tier 1 expectations.
✅ Costs & margins: Competitive ($1,000/oz AISC) and profitable even at conservative gold prices — good, though not exceptional.
⚠️ Jurisdiction & risk: Ecuador is better than it was but still riskier than top Tier 1 regions (like Canada, Australia).
❌ Proven performance: Not yet — still unbuilt, no operational track record.
⚖️ Conclusion:
Cangrejos is a Tier 1‑scale project — its size and mine life put it firmly in that league.
However, it is not yet a Tier 1 mine, because:
it is not producing yet,
and its jurisdictional risk & unproven operations make it less certain than classic Tier 1 mines.
It’s more accurate to say:
📝 Cangrejos is a potential Tier 1 asset — but whether it becomes a true Tier 1 mine depends on successful construction, stable operations, and how Ecuador’s political & social environment evolves.
