Summary
Aya Gold & Silver has filed an updated Preliminary Economic Assessment (PEA) for the Boumadine Polymetallic Project in Morocco. The 2026 PEA reports a significantly improved economic profile with a base case NPV (5%) of $3.5B and an IRR of 93%, supported by an extended 14-year mine life.
Reasoning: The updated PEA shows substantial economic improvements in NPV, IRR, and mine life compared to the previous study, driven by higher price assumptions and improved payability.
Positive factors
- Significant NPV improvement (doubled from prior PEA)
- Strong IRR of 93% in base case
- Extended mine life from 11 to 14 years
- Increased metal payability for gold and silver
- Strong capital efficiency ratio (7.6x)
Negative factors
- Project is in preliminary stage (PEA)
- Includes significant Inferred resource component

Tags used in scoring
Indicated Resourcepositive
Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.
Why it applies: category is "indicated"
Cut-off Undisclosednegative
High-grade interval reported without stating the cut-off grade used for compositing.
Why it applies: no cutoff_grade was stated
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: qp_signed is true
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: reporting_standards includes ni_43_101
Resource Updateneutral
Revised estimate for an existing resource — compare to prior to assess progress.
Why it applies: the release compares against a previous estimate
PEA-Supportingneutral
Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.
Why it applies: the release names the study this estimate supports
DFS-Supportingneutral
Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.
Why it applies: the release names the study this estimate supports

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.
