Summary

Collective Mining has announced strong metallurgical results for its Apollo deposit at the Guayabales Project in Colombia, demonstrating high recoveries for gold, silver, copper, and tungsten using conventional processing methods. The company is advancing an integrated flowsheet to support a planned 2027 licensing submission. The release also includes details of the maiden mineral resource estimate for Apollo, effective August 31, 2026, which outlines significant indicated and inferred resources across multiple metals.

Reasoning: The document highlights strong metallurgical results for multiple commodities and details an integrated processing strategy, which de-risks the project. The accompanying maiden mineral resource estimate provides a substantial base, further enhancing the project's potential. While some metallurgical results are historical, the overall advancement towards a licensing submission is a significant positive.

Positive factors

  • Strong metallurgical recoveries for gold, silver, copper, and tungsten using conventional methods, supporting project viability.
  • Advancement of an integrated processing flowsheet tailored to the deposit's metal distribution, indicating a clear development path.
  • Maiden Mineral Resource estimate provides a solid foundation for the project, with significant indicated and inferred resources across multiple metals.
  • High M&I percentage in the resource estimate (43.4% of total contained AuEq) indicates good geological confidence.

Negative factors

  • The metallurgical results for the Apollo master composite are historical, having been disclosed in August 2026.
  • The resource estimate is a maiden resource, which typically has a higher inferred component, and a significant portion of the contained metal is in the inferred category.

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 29

Classification and evidence

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: Ned Jalil, P.Eng., Chief Executive Officer of the Company and a Qualified Person as defined by National Instrument 43-101, has reviewed and approved the scientific and technical information.

Evidence · text

“Ned Jalil, P.Eng., Chief Executive Officer of the Company and a Qualified Person as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101"), has reviewed and approved the scientific and technical information contained in this news release.”

NI 43-101 Compliantpositive

Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.

Why it applies: The Mineral Resource is classified in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves, and the QP is defined by National Instrument 43-101.

Evidence · text

“Mineral Resources are classified in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves.”

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 document explicitly states 'Apollo Maiden Mineral Resource (announced September 8, 2026)'.

Evidence · text

“Apollo Maiden Mineral Resource (announced September 8, 2026)”

High Recoverypositive

Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: The Apollo master composite achieved 95% gold, 92% silver, and 85% copper recovery, which are strong to exceptional for conventional processing methods.

Evidence · table

“95% gold, 92% silver, and 85% copper recovery using conventional processing methods”

Context: Au: 1.4 g/t Ag: 20 g/t Cu: 0.08%

Pilot Scale Completepositive

Pilot or demonstration plant testing completed under continuous operation.

Why it applies: The Apollo master composite test work is described as 'Locked-cycle testing', which is a strong indicator of test scale maturity.

Evidence · table

“Apollo master composite / Locked-cycle testing”

Context: Au: 1.4 g/t Ag: 20 g/t Cu: 0.08%

Mill Routeneutral

Processing via mill or concentrator (CIL, CIP, tank leach, flotation).

Why it applies: The processing strategy involves 'conventional cyanidation circuit' and 'flotation' for different material types.

Evidence · text

“The majority of the Mineral Resource, where copper and tungsten grades are low, will be processed through a conventional cyanidation circuit with low reagent consumption to produce gold and silver doré. The higher-grade copper and tungsten sub-domains which are contained mostly within the Open Pit portion of the mineral resource will be selectively routed through dedicated flotation concentrate circuits designed to recover those metals.”

Recovery Improvingpositive

Recovery improved versus a like-for-like prior test program on the same domain and route.

Why it applies: The document states '95% copper, 90% gold and 94.4% silver recovery through gravity, flotation and cyanidation' for the copper sub-domain composite, which is a new result and shows high recoveries.

Evidence · table

“95% copper, 90% gold and 94.4% silver recovery through gravity, flotation and cyanidation”

Context: Au: 1.16 g/t Ag: 71 g/t Cu: 0.42%

Cut-off Disclosedpositive

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

Why it applies: A current resource fact retains the disclosed cut-off grade

Gravity Routeneutral

Gravity separation forms a material part of the flowsheet.

Why it applies: the document describes a gravity route ("gravity")

Multi-Domain Testedpositive

Variability across ore domains (oxide, transition, fresh) has been addressed.

Why it applies: 3 distinct composites were tested

Reasoning: An inferred silver resource in the underground Ramp Zone, adding to the polymetallic nature of the deposit, but with lower confidence due to its category.

Positive factors

  • Inferred silver resource in the underground Ramp Zone, contributing to polymetallic potential.
  • Maiden resource estimate provides a new baseline for the project.

Negative factors

  • Inferred category has lower geological confidence.

Tags used in scoring

Inferred Resourcenegative

Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: category is "inferred"

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

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

No Contained Metalnegative

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

Why it applies: contained_metal was not reported

Reasoning: Moderate tungsten recovery from new test work on a specific sub-domain, indicating a viable processing route, though the test scale and variability are not fully detailed.

Positive factors

  • Moderate tungsten recovery of up to 74% through gravity and flotation.
  • New test results, adding novel information to the project's metallurgical understanding.

Negative factors

  • The test scale is not explicitly stated beyond 'test work', suggesting it might be bench-scale.
  • The 'up to 74%' implies variability or a best-case scenario.

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.
