## Minestarters Atlas summary

GoldMining Inc. announced an updated Preliminary Economic Assessment \(PEA\) for its La Mina Project in Colombia, highlighting a $1.0 billion after-tax Net Present Value \(NPV\) and a 32.2% Internal Rate of Return \(IRR\). This updated PEA, which represents a 265% increase in after-tax NPV from the prior assessment, outlines a conventional open-pit operation with an 11.2-year mine life. The project is projected to produce an average of 152.4 koz gold equivalent annually over the first five years, with high metallurgical recoveries for gold, copper, and silver.

Reasoning: The updated Preliminary Economic Assessment for the La Mina Project demonstrates significantly improved project economics with a $1.0 billion after-tax NPV and 32.2% IRR, representing a 265% increase from the prior PEA, supported by a robust production profile and high metallurgical recoveries for gold, copper, and silver.

## Classification and evidence

**PEA-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.

Why it applies: The document is an updated Preliminary Economic Assessment \(PEA\) for the La Mina Project.

Evidence · text

> updated preliminary economic assessment

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The document presents an updated PEA which includes a review of the existing Mineral Resource Estimate.

Evidence · text

> updated preliminary economic assessment

**QP/CP Signed**

Polarity: positive

Definition: 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: The PEA was prepared by independent Qualified Persons Scott E. Wilson, Zeke Blakeley, and Rick Jordan, as defined in NI 43-101.

Evidence · text

> The PEA was prepared for the Company by Scott E. Wilson, CPG, Zeke Blakeley, SME-RM, and Rick Jordan, SME-RM, each of which is independent of the Company and a Qualified Person, as such term is defined in NI 43-101.

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: The disclosure regarding the Project, including the PEA and Mineral Resource estimates, has been prepared in accordance with NI 43-101.

Evidence · text

> Disclosure regarding the Project, including the PEA and Mineral Resource estimates included herein, has been prepared by the Company in accordance with NI 43-101.

**Inferred Resource**

Polarity: negative

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

Why it applies: The PEA includes Inferred Mineral Resources, which are considered too speculative geologically to be categorized as Mineral Reserves.

Evidence · text

> The PEA includes Inferred Mineral Resources, which are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves.

**Stale Estimate**

Polarity: negative

Definition: Effective date is >2 years old — data currency concern, may not reflect current geological understanding.

Why it applies: The Mineral Resource Estimate used for the PEA has an effective date of December 20, 2022, which is over two years old at the time of this announcement \(April 28, 2026\).

Evidence · text

> current MRE with effective date December 20th, 2022

**Cut-off Disclosed**

Polarity: positive

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

Why it applies: The cut-off grade of 0.30 g/t Au for the Mineral Resource Estimate is explicitly stated.

Evidence · table

> 0.30

Context: Cut-Off Grade: 0.30 g/t Au.

**High Recovery**

Polarity: positive

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

Why it applies: Gold metallurgical recovery is reported at 91%, which is exceptional for a mill/CIL processing route.

Evidence · table

> 91

Context: Average gold metallurgical recovery

**Mill Route**

Polarity: neutral

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

Why it applies: The processing flowsheet utilizes conventional grinding and flotation followed by a leach circuit.

Evidence · text

> conventional grinding and flotation to generate a copper concentrate, with tailings of the copper process reporting to a leach circuit to generate gold-silver doré on site.

**Open Pit**

Polarity: neutral

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The PEA contemplates a conventional open-pit truck-and-shovel operation.

Evidence · text

> conventional open-pit truck-and-shovel operation

## 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.
