## Minestarters Atlas summary

Orestone Mining Corp. has signed an option agreement to earn up to an 85% interest in the Francisca gold property in Salta Province, Argentina. The property features a large oxide gold stock-work system with historic high-grade intercepts, targeting open-pit mining and heap leach recovery.

Reasoning: The company has secured an option to a significant gold system with high-grade historic potential, though technical risk is elevated due to the reliance on non-compliant historical data and poor previous drilling orientation.

- Positive factor: Acquisition of a large \(7 sq km\) oxide gold system

- Positive factor: Potential for bulk tonnage open pit and heap leach mining

- Positive factor: High-grade historic intercepts up to 109 g/t Au

- Positive factor: Significant strike length and width indicated by mapping

- Negative factor: Data is historical and non-NI 43-101 compliant

- Negative factor: Previous drilling was poorly oriented and did not adequately test the target

- Negative factor: Orestone does not possess the original detailed assay data

Facts used in scoring: 6

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Historic reports note grades up to 109 g/t gold.

Evidence · text

> grades from 1 to 109 g/t gold

**No QA/QC Disclosure**

Polarity: negative

Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.

Why it applies: The document explicitly states that historic trenching data is non-43-101 compliant and the company lacks detailed assay data.

Evidence · text

> The observations of gold assay values in the trenches are non-43-101 compliant due to their historic nature

## 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.
