## 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 advancing two CAPEX configurations, including a hybrid model that integrates an Enduring Energy Storage system to provide thermal pre-treatment.

Reasoning: The company has successfully de-risked the technical pathway for high-purity silica production through complementary leaching test work, moving towards CAPEX definition.

- Positive factor: Confirmed preferred purification pathway \(+4N silica\)

- Positive factor: Integration of energy storage system to reduce CAPEX/OPEX

- Positive factor: Successful R&D testing at 1,000°C

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 purification process involves acid leaching and calcination, which are part of a mill/processing plant flowsheet.

Evidence · text

> calcination \(thermal treatment\) followed by acid leaching of the silica feedstock

**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.
