## Minestarters Atlas summary

Lahontan Gold Corp. reported high cyanide \(CN\) extractable recoveries of 81% for gold and 60% for silver from pulp samples at the West Santa Fe project. These results exceed historical projections and support the potential for heap leach processing.

Reasoning: The cyanide extraction results \(81% Au, 60% Ag\) are high and exceed historical projections, supporting the amenability of the project to heap leach processing.

- Positive factor: High cyanide extraction rates for both gold and silver

- Positive factor: Results exceed historical projected recoveries

- Positive factor: QA/QC protocols clearly disclosed

- Positive factor: Validates previous metallurgical testing

- Negative factor: Results are based on pulp samples from RC drilling rather than full-scale metallurgical testing

Facts used in scoring: 2

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Gold recovery of 81% is high for cyanide extraction.

Evidence · text

> This is a very high CN extraction ratio

**QA/QC Disclosed**

Polarity: positive

Story-specific tag

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release details specific QA/QC protocols including blanks, CRMs, and duplicates.

Evidence · text

> Lahontan conducts an industry standard QA/QC program

**Heap Leach Route**

Polarity: neutral

Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.

Why it applies: The testing was designed to mimic potential cyanide heap leach processing.

Evidence · text

> mimics potential gold and silver recoveries utilizing CN heap leach processing

## 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.
