## Minestarters Atlas summary

Erdene Resource Development has released a preliminary economic assessment for its Zuun Mod molybdenum-copper project in Mongolia, outlining a $687 million development plan. The study estimates an after-tax NPV of $745 million and an IRR of 16% based on a base case scenario.

Reasoning: The announcement of a PEA for the Zuun Mod project shows strong economic potential with a high NPV, though geological confidence is currently limited by a high Inferred resource component.

- Positive factor: Strong NPV of $745M at 8% discount rate

- Positive factor: Significant upside potential at higher metal prices

- Positive factor: Large resource base with significant molybdenum content

- Positive factor: Strategic location near infrastructure development

- Negative factor: High proportion of Inferred resources \(74% of plant feed\)

- Negative factor: Preliminary nature of the assessment \(PEA\)

- Negative factor: Significant capital expenditure required \($687M build\)

Facts used in scoring: 4

## Classification and evidence

**Inferred Resource**

Polarity: negative

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

Why it applies: 74% of the proposed plant feed is in the Inferred category.

Evidence · text

> Inferred resources account for about 74% of the proposed plant feed

**Maiden Resource**

Polarity: neutral

Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component.

Why it applies: The document describes a preliminary economic assessment for the Zuun Mod project.

Evidence · text

> The preliminary economic assessment gives Erdene a potential second development centre

#### Tags used in scoring

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: category is "indicated"

**Cut-off Undisclosed**

Polarity: negative

## 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.
