## Minestarters Atlas summary

Rock Tech Lithium has completed pilot-scale ore-sorting test work at its Georgia Lake Lithium Project in Ontario. The results indicate a potential to reduce crushing and concentrator capital costs by up to 50% and improve ore quality by 1.4x to 1.8x through waste removal.

Reasoning: The announcement reports successful pilot-scale ore-sorting test work that suggests significant potential for CAPEX reduction and grade improvement, though these are not yet confirmed in a formal study.

- Positive factor: Ore-sorting test work demonstrated significant waste removal \(25-45%\)

- Positive factor: Potential to reduce crushing and concentrator CAPEX by up to 50%

- Positive factor: Upgrade factor of 1.4x to 1.8x identified for ore stream

- Negative factor: Results are preliminary and based on limited-scale pilot testing

- Negative factor: Economic benefits are conceptual and require further engineering/DFS validation

Facts used in scoring: 2

## Classification and evidence

**Bench Scale Only**

Polarity: negative

Definition: Only preliminary bench tests completed — no locked-cycle or pilot work.

Why it applies: Test work was conducted using pilot-scale equipment on limited sample sets and is described as preliminary.

Evidence · text

> The ore-sorting test work results described above are preliminary in nature and based on limited-scale testing.

**High Recovery**

Polarity: positive

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

Why it applies: While specific recovery % isn't given, the upgrade factor of 1.4x-1.8x and 25-45% waste removal indicates high efficiency in pre-concentration.

Evidence · text

> Ore-sorting test work removed approximately 25 to 45 per cent of waste material

**Mill Route**

Polarity: neutral

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

Why it applies: the document describes a mill\_cil route \("concentrator"\)

**Single Domain Only**

Polarity: negative

Definition: Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was 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.
