RE: Resource Estimates5 Jun 2025 18:30
JORC and different levels of MRE are far above my head. But I asked ChatGPT, more out of interest in AI than something to hang my hat on. Here’s what it said:
“ Based on what we know so far, Empire Metals is most likely targeting an Indicated Mineral Resource Estimate (MRE) for its Pitfield Project, not a Measured one — at least for the maiden MRE planned for Q3 2025. Here’s why:
⸻
1. Typical Progression of MREs
• Measured resources require very high confidence in geological continuity and grade distribution.
• Indicated is one step below and allows for some variability but still supports mine planning.
• Inferred is the lowest confidence level, suitable only for preliminary assessments.
A maiden MRE — especially in an emerging project — is almost always Indicated or Inferred because companies are usually building toward Measured status over time with tighter drill spacing and additional data.
⸻
2. Drill Program Scope
• Empire has reported a significant drill campaign: 15,000+ meters of RC drilling, 2,000+ meters of diamond core drilling, and an upcoming 36,000 meters more.
• This suggests they’re working toward an Indicated classification—a level needed for economic studies (like a Preliminary Economic Assessment or Scoping Study), but likely not yet sufficient for Measured, which typically needs very dense drilling grids.
⸻
3. Language and Milestones
• The company has consistently referred to the upcoming MRE as maiden, and has not used “Measured” in any public statements.
• When companies expect a Measured resource, they explicitly state it due to its higher value for shareholders and technical credibility.
⸻
Conclusion
Unless Empire surprises with an exceptionally detailed geological model and dense drilling pattern (which doesn’t appear to be the case yet), the maiden MRE will most likely be classified as Indicated, potentially with some portions Inferred.
A Measured MRE would more likely follow in subsequent updates, once they’ve further delineated high-confidence zones.
