# Savannah is pleased to announce that the ongoing metallurgical test work programme associated Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/savannah-is-pleased-to-announce-that-the-ongoing-metallurgical-test-work-program--624f696b-49f0-430f-9462-353f346ca322 Original source: https://www.rns-pdf.londonstockexchange.com/rns/1313T_1-2020-7-15.pdf Publisher: research Original announcement: Unknown date Analysis by Minestarters Atlas Atlas analysis published: 2026-11-08T14:08:52.764Z Atlas analysis updated: 2026-11-08T14:08:52.764Z - Company: Unavailable - Ticker: SAV - Exchange: LSE - Region: Portugal - Primary commodity: Lithium - Secondary commodities: None reported - Document categories: Metallurgy, Other - Extracted: 2026-11-08 14:08:52 UTC Narrative sentiment: 0.75 · Bullish ## Minestarters Atlas summary Savannah reported strong early metallurgical results for Mina do Barroso spodumene concentrate, with 96% conversion to the acid-soluble beta phase and water leach extraction up to 94.6%. The third stage of battery-grade lithium hydroxide testing was postponed due to COVID-19 restrictions at the laboratory, so the programme remains incomplete. Reasoning: The release reports strong lithium conversion and leach results from early-stage metallurgical test work on Mina do Barroso concentrate, but the programme is incomplete because the final purification/crystallization stage was postponed. - Positive factor: "excellent results" from metallurgical test work - Positive factor: "High lithium recovery rates were achieved" - Positive factor: 96% conversion to the acid-soluble beta phase - Positive factor: Lithium extraction of up to 94.6% was achieved - Positive factor: Competent Person review disclosed for metallurgy - Negative factor: third stage postponed due to COVID-19 related restrictions - Negative factor: laboratory work is ongoing and phase 3 not yet completed - Negative factor: no quantitative details on purification/crystallization stage Facts used in scoring: 0 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The release describes conventional calcination, leaching, purification and crystallization rather than a mining or drilling event. Evidence · text > conventional processing \(calcination/acid roasting and water leaching\) **QP/CP Signed** Polarity: positive Story-specific tag Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: The metallurgy was reviewed by Mr Tim Newton, who is stated to qualify as a competent person. Evidence · text > has been reviewed by Mr Tim Newton **Byproduct Commodity** Polarity: neutral Definition: The tested commodity is a byproduct rather than the primary economic driver. Why it applies: The testwork is on spodumene concentrate to produce lithium chemicals, which is the target product rather than a byproduct context. Evidence · text > spodumene concentrate for the production of battery grade, lithium chemicals **POX/BIOX Route** Polarity: neutral Definition: Pressure or bio-oxidation for refractory ore — high CAPEX and OPEX. Why it applies: the document describes a pox\_biox route \("roasting"\) ## Extracted facts Stored fact records: 0. Some facts used in scoring do not have a stored record. No stored fact records are available for this extraction. ## 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.
