## Minestarters Atlas summary

Tungsten Mining has successfully produced saleable tungsten concentrate from its Watershed project in Queensland, with grades reaching up to 65.9% WO3. The metallurgical results, which include recoveries of 60-70% and low sulphur levels, support the upcoming Definitive Feasibility Study \(DFS\) and a targeted late-2026 Final Investment Decision \(FID\).

Reasoning: Successful metallurgical test work producing high-grade tungsten concentrate advances the project toward DFS and FID.

- Positive factor: High concentrate grades achieved \(up to 65.9% WO3\)

- Positive factor: Low sulphur content in concentrate \(0.02%\)

- Positive factor: Successful production of saleable concentrate

- Positive factor: Advancement toward DFS and FID

- Negative factor: Recovery rates \(60-70%\) are moderate for the commodity

Facts used in scoring: 4

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The company plans to use flotation and gravity separation.

Evidence · text

> plans to produce concentrate using conventional ore sorting, gravity separation and flotation

**Gravity Route**

Polarity: neutral

Definition: Gravity separation forms a material part of the flowsheet.

Why it applies: the document describes a gravity route \("gravity"\)

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 2 distinct composites were tested

## 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.
