## Minestarters Atlas summary

Tintina Mines has completed its 2025 drilling campaign at the Domeyko Sulfuros Project in Chile. Preliminary metallurgical testwork shows favorable copper and gold recoveries, supporting the upcoming Preliminary Economic Assessment \(PEA\).

Reasoning: The announcement reports strong preliminary metallurgical recoveries \(92.6% Cu\) and confirms the completion of a drilling campaign, though full assay results are still pending.

- Positive factor: high copper recovery

- Positive factor: good mineral liberation

- Positive factor: QP sign-off

- Negative factor: incomplete assay results

Facts used in scoring: 2

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: 92.6% Cu recovery in flotation is at the top of the strong/exceptional band.

Evidence · text

> yielded average recoveries of 92.6% Cu

**QP/CP Signed**

Polarity: positive

Story-specific tag

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: Mr. José Luis Bello Soto, a qualified person, has reviewed and approved the release.

Evidence · text

> reviewed and approved by Mr. José Luis Bello Soto... a “qualified person”

**Mill Route**

Polarity: neutral

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

Why it applies: The report describes flotation and grinding circuits.

Evidence · text

> supporting the design of a conventional grinding circuit

## 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.
