## Minestarters Atlas summary

Rio Silver reported initial metallurgical results from the Maria Norte property in Peru, demonstrating high recoveries for silver, gold, and lead using flotation. The tests produced two concentrates with low arsenic levels, supporting the company's processing strategy.

Reasoning: Initial flotation test work on a bulk sample shows strong recoveries for silver \(85%\), gold \(74%\), and lead \(77%\) with low arsenic penalties.

- Positive factor: High silver and gold recoveries

- Positive factor: Low arsenic levels in concentrates

- Positive factor: High grade concentrates

- Negative factor: Initial test work scale is limited \(bulk sample from surface showing\)

Facts used in scoring: 9

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Silver recovery of 85% is in the exceptional/strong band for flotation.

Evidence · text

> Initial Silver - Gold - Lead Recoveries of 85 %, 74 % and 77%

**Free Milling**

Polarity: positive

Definition: Simple, clean ore amenable to standard processing without oxidation.

Why it applies: The release mentions low arsenic and successful flotation of quartz-lead veins.

Evidence · text

> concentrates are expected to contain low amounts of arsenic
