# PL3: Well 9 Drilling Completed Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/pl3-well-9-drilling-completed--1ee518c2-9771-41cd-bf93-9b4071a317e3 Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03149427 Publisher: asx Original announcement: 2026-10-06T22:45:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-06T23:06:25.531Z Atlas analysis updated: 2026-10-06T23:06:25.531Z - Company: Patagonia Lithium Ltd - Ticker: PL3 - Exchange: ASX - Region: Jujuy province, Argentina - Primary commodity: Lithium - Secondary commodities: Gypsum - Document categories: Drill results, Metallurgy - Extracted: 2026-10-06 23:06:26 UTC Narrative sentiment: 0.10 · Bullish ## Minestarters Atlas summary Patagonia Lithium has completed infill drilling at Well 9 \(JAM 26-09\) to a depth of 230m. While the well did not yield multiple brine assays, it successfully conducted a packer test showing brine flow of 66 L/hr and provided samples for Ekosolve pilot plant testing. Reasoning: The announcement reports the completion of an infill well \(Well 9\) that failed to provide significant new lithium assays but successfully conducted a packer test for brine flow. While the drilling itself was limited, the metallurgical sampling for pilot testing and the packer test results provide technical data for the upcoming MRE upgrade. - Positive factor: Successful packer test with reasonable brine flow - Positive factor: Information valuable for modelling aquifers - Positive factor: Brine samples shipped for pilot plant testing - Negative factor: Inability to acquire more than one brine assay - Negative factor: Drilling stopped at 230m due to lack of assays - Negative factor: Clays encountered represent a basement layer with low porosity Facts used in scoring: 3 ## Classification and evidence **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The well was designed to infill existing drilling. Evidence · text > Well 9, which designed to infill existing drilling **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release details sampling techniques, laboratory use \(Alex Stewart, Analytics NOA\), and use of standards/blanks. Evidence · text > A distilled water sample and a lithium standard sample C 3001 \(400ppm\) was supplied to Alex Stewart labs. **Gravity Route** Polarity: neutral Definition: Gravity separation forms a material part of the flowsheet. Why it applies: the document describes a gravity route \("gravity"\) **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 3.

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.
