Summary
Outcrop Silver & Gold Corporation announced an updated Mineral Resource Estimate for its Santa Ana Primary Silver Project in Colombia. The Updated MRE reports 29.9 million ounces (Moz) silver-equivalent (AgEq) in the Indicated category at 518.7 g/t AgEq, and 27.9 Moz AgEq in the Inferred category at 368.5 g/t AgEq. This represents a 23.5% increase in Indicated AgEq ounces and a 106.3% increase in Inferred AgEq ounces compared to the maiden MRE, with the estimate applying a more rigorous classification standard.
Reasoning: The updated Mineral Resource Estimate for the Santa Ana project demonstrates substantial growth in contained silver equivalent ounces, particularly in the Inferred category, while maintaining very high average grades relative to global epithermal silver deposits. The application of a more rigorous classification standard and clear economic assumptions enhance the credibility and future potential of the project.
Positive factors
- Significant increase in contained silver equivalent ounces in both Indicated (+23.5%) and Inferred (+106.3%) categories, demonstrating substantial resource growth.
- High average silver equivalent grades (518.7 g/t AgEq Indicated, 368.5 g/t AgEq Inferred) and high average silver grades (376.4 g/t Ag Indicated, 266.4 g/t Ag Inferred) compared to global epithermal silver deposits.
- Application of a more rigorous classification standard, including RPEEE and MSO, enhances the confidence and quality of the resource estimate.
- The estimate is NI 43-101 compliant and signed off by a Qualified Person, ensuring adherence to industry best practices.
- Detailed disclosure of metal equivalent assumptions (prices, recoveries) and cut-off grade parameters provides transparency.
- Significant exploration upside remains with twelve known veins yet to be drill tested and a pipeline of untested anomalies.
Negative factors
- The resource is reported with two different cut-off grades (95 g/t AgEq and 130 g/t AgEq) depending on the vein area, which can complicate direct comparisons across the project.
Low confidence — this extraction should be reviewed alongside the original source.
Facts used in scoring: 84
Classification and evidence
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.

Contained Metal Growthpositive
True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.
Why it applies: Contained AgEq ounces in Indicated resources in the Updated MRE increased 23.5% compared to the maiden mineral resource estimate, and Inferred resources increased 106.3% to 27.9 Moz AgEq.
Evidence · text
“Contained AgEq ounces in Indicated resources in the Updated MRE increased 23.5% compared to the maiden mineral resource estimate for the Santa Ana Project outlined in a technical report dated June 8, 2023 (the " Maiden MRE "). Inferred resources increased 106.3% to 27.9 Moz AgEq.”
Category Upgradepositive
Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal.
Why it applies: Mineral Resource classification in the Updated MRE applied a more rigorous standard than the Maiden MRE, including constraining resources based on reasonable prospects for eventual economic extraction (" RPEEE ") and mineable shape optimization (" MSO ").

Reasoning: The El Dorado vein area contributes a high-grade Indicated resource, significantly enhancing the overall project's value and confidence.
Positive factors
- Indicated resource category provides higher confidence for future development.
- Exceptionally high silver grade (502.3 g/t Ag) for an underground resource, well above the 75th percentile for epithermal silver deposits.

Reasoning: The La Isabela vein area contributes a moderate Inferred resource with a good silver equivalent grade, indicating some potential for future conversion.
Positive factors
- Inferred resource tonnage and contained metal, indicating future growth potential.
- High silver equivalent grade (249.2 g/t AgEq) for an underground resource.
Negative factors
- Inferred category has lower geological confidence.

Reasoning: The Morena vein area contributes a substantial Inferred resource with a high silver grade, indicating strong potential for future conversion to higher confidence categories.
Positive factors
- Significant Inferred resource tonnage and contained metal, indicating future growth potential.
- High silver grade (285.2 g/t Ag) for an underground resource, exceeding the 75th percentile for epithermal silver deposits.
Negative factors
- Inferred category has lower geological confidence.

Reasoning: The total Inferred resource demonstrates significant contained silver ounces at a high average grade, indicating strong potential for future conversion to higher confidence categories.
Positive factors
- Substantial Inferred resource (2.35 Mt) with high contained metal (20.1 Moz Ag), indicating significant future growth potential.
- High average silver grade (266.4 g/t Ag) for an underground resource, exceeding the 75th percentile for epithermal silver deposits.
Negative factors
- Inferred category has lower geological confidence.
- The total resource is derived from areas with two different cut-off grades (95 g/t AgEq and 130 g/t AgEq).

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 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
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

Reasoning: The total Inferred resource includes a significant gold component, adding to the polymetallic nature and overall value of the project.
Positive factors
- Gold contributes to the overall value of the resource.
Negative factors
- Inferred category has lower geological confidence.
- The total resource is derived from areas with two different cut-off grades (95 g/t AgEq and 130 g/t AgEq).

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.
