Minestarters Atlas analysis

Summary

Granada Gold has announced an updated 2026 Mineral Resource Estimate for its Granada Gold Project in Quebec, showing a 64% increase in Measured and Indicated resources to 890,600 oz Au and a 90% increase in Inferred resources to 865,500 oz Au. The growth is largely attributed to the higher gold price environment supporting lower economic cut-off grades.

Reasoning: The update shows substantial growth in both tonnage and contained gold ounces across all categories, primarily driven by the higher gold price allowing for lower cut-off grades.

Positive factors

  • Significant tonnage growth in M&I (+64%) and Inferred (+90%)
  • Contained metal growth driven by higher gold price environment
  • QP/CP sign-off provided by Claude Duplessis, P.Eng.
  • Cut-off grades lowered to capture more material at current prices
  • Deposit remains open along strike and at depth

Negative factors

  • Average grade declined due to lower cut-off grades
  • Resource is not yet a reserve

Facts used in scoring: 5

Classification and evidence

Tonnage Growthpositive

Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved.

Why it applies: M&I tonnage increased by 64% and Inferred by 90% compared to the 2022 estimate.

Evidence · text

“64% increase in Measured and Indicated contained gold and a 90% increase in Inferred contained gold”

QP/CP Signedpositive

Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.

Why it applies: Claude Duplessis, P.Eng. of GoldMinds Geoservices Inc. is named as the independent Qualified Person.

Evidence · text

“prepared by Claude Duplessis, ing. (P.Eng.), of GoldMinds Geoservices Inc., an independent Qualified Person”

Cut-off Disclosedpositive

Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: Cut-off grades for in-pit (0.25 g/t Au) and underground (1.4 g/t Au) are clearly stated.

Evidence · text

“Pit-constrained resources reported at a 0.25 g/t Au cut-off; underground resources at a 1.4 g/t Au cut-off.”

Maiden Resourceneutral

First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable.

Why it applies: The project is an update to a 2022 estimate, not a maiden resource.

Evidence · text

“re-evaluates the independent SGS Canada Inc. block model that supported the Company’s 2022 estimate”

Reasoning: Explicit resource disclosure recovered from source prose.

Evidence · text

“As expected, when a deposit is re-evaluated at a materially higher gold price, the average grade of the reported resource is lower than in 2022, because lower-grade material that was previously below the cut-off grades applied in 2022 is captured within the reported resource at the lower cut-off grades applied in 2026.”

Tags used in scoring

Cut-off Lowerednegative

Cut-off grade reduced beyond the suspicious bound vs prior estimate — tonnage growth may be artificial inflation.

Why it applies: As expected, when a deposit is re-evaluated at a materially higher gold price, the average grade of the reported resource is lower than in 2022, because lower-grade material that was previously below the cut-off grades applied in 2022 is captured within the reported resource at the lower cut-off grades applied in 2026.

Context: Noranda, Quebec

Cut-off Undisclosednegative

High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff_grade was stated

No Contained Metalnegative

Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.

Why it applies: contained_metal was not reported

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.
