## Minestarters Atlas summary

Patagonia Lithium has completed a successful 72-hour pump test at Well 8 on the Cilon concession. The test achieved a flow rate of 2,043 L/h and confirmed lithium concentrations of up to 232 mg/L in the brine, validating the aquifer's potential.

Reasoning: The pump test successfully demonstrated hydraulic conductivity and confirmed lithium concentrations in the target aquifer, which is a key de-risking milestone for a brine project.

- Positive factor: Strong aquifer performance with high flow rate \(2,043 L/h\)

- Positive factor: Rapid water level recovery

- Positive factor: Confirmation of lithium-rich brines \(232 mg/L\) in the main aquifer interval

- Positive factor: Successful packer tests

## 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.
