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 factors
- Confirmed preferred purification pathway (+4N silica)
- Integration of energy storage system to reduce CAPEX/OPEX
- Successful R&D testing at 1,000°C
Facts used in scoring: 1
Classification and evidence
Mill Routeneutral
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.

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.
