## Minestarters Atlas summary

Homerun Resources has confirmed that calcination followed by acid leaching is the preferred pathway to produce +4N high-purity silica at its Santa Maria Eterna project. The company is now advancing CAPEX studies for two configurations, including a hybrid model that integrates an Enduring Energy Storage system.

Reasoning: The company has successfully identified a preferred metallurgical pathway \(calcination + acid leaching\) to reach +4N purity, de-risking the technical route for their high-value silica products.

- Positive factor: Confirmed preferred purification pathway

- Positive factor: Integration of energy storage with processing

- Positive factor: Strategic partnership with Anzaplan and NLR

- Negative factor: CAPEX configurations still in development

Facts used in scoring: 1

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The process involves acid leaching and thermal treatment, characteristic of a mill/concentrator 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.
