Summary
Mako Mining has released an updated Mineral Resource Estimate for the Moss Mine in Arizona, reporting 646,000 ounces of gold and 6.8 million ounces of silver within Measured and Indicated categories. The resource is based on an optimized open pit shell with a 0.17 g/t AuEq cut-off grade.
Reasoning: Updated M&I resource for an existing open pit project with high-grade silver credits and clear technical sign-off.
Positive factors
- NI 43-101 compliant
- QP/CP signed
- Cut-off grade disclosed
- Open pit resource
Negative factors
- Significant Inferred component
Facts used in scoring: 14
Classification and evidence
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: The resource estimate is reported in accordance with NI 43-101 standards.
Evidence · text
“in accordance with National Instrument 43-101”
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: Qualified Persons Chris Keech and Gary Wong are named and have verified the data.
Evidence · text
“Mr. Chris Keech, P.Geo. of CGK Consulting Services Inc., meets the requirements of a Qualified Person”
Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: The estimate includes an Inferred component which is speculative in nature.
Evidence · text
“There is an additional estimated Inferred open pit mineral resource”
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: The cut-off grade of 0.17 g/t AuEq is clearly stated.
Evidence · text
“at a 0.17 g/t AuEq 1 cutoff”

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 Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: cutoff_grade is 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

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.
