## Minestarters Atlas summary

Lundin Gold has discovered a fifth porphyry, extending its porphyry corridor to 10km at the Fruta del Norte mine in Ecuador. The drilling at Sandia returned the highest grade intercept to date, including 322 metres of 1.08% CuEq.

Reasoning: The announcement reports a major discovery \(fifth porphyry\) and a significant high-grade, wide intercept \(322m @ 1.08% CuEq\) that extends the known corridor.

- Positive factor: Discovery of fifth porphyry

- Positive factor: Extension of porphyry corridor to 10km

- Positive factor: Highest grade intercept to date at Sandia

- Positive factor: Significant width of 322m at 1.08% CuEq

Facts used in scoring: 1

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The announcement states the porphyry corridor has been extended to 10km.

Evidence · text

> Extends Porphyry Corridor to 10km's

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: The 322m intercept at 1.08% CuEq is exceptionally large and high-grade for a porphyry system.

Evidence · text

> 322 Metres of 1.08% CuEq

#### Tags used in scoring

**No QA/QC Disclosure**

Polarity: negative

Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.

Why it applies: qaqc\_disclosed is not true

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**Metal Equivalent Opaque**

Polarity: negative

Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used.

Why it applies: an equivalent grade is reported without its assumptions

## 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.
