Analysis by Minestarters Atlas

Atlas analysis published:

Minestarters Atlas analysis

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 factors

  • "excellent results" from metallurgical test work
  • "High lithium recovery rates were achieved"
  • 96% conversion to the acid-soluble beta phase
  • Lithium extraction of up to 94.6% was achieved
  • Competent Person review disclosed for metallurgy

Negative factors

  • third stage postponed due to COVID-19 related restrictions
  • laboratory work is ongoing and phase 3 not yet completed
  • no quantitative details on purification/crystallization stage

Facts used in scoring: 0

Classification and evidence

Mill Routeneutral

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 Signedpositive · Story-specific tag

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 Commodityneutral

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 Routeneutral

Pressure or bio-oxidation for refractory ore — high CAPEX and OPEX.

Why it applies: the document describes a pox_biox route ("roasting")

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.
