Summary
Savannah reports a 17% increase in the Mina do Barroso JORC Mineral Resource to 23.5Mt at 1.02% Li2O, with 241,000t contained Li2O. The update also lifts Measured and Indicated tonnage to 13.3Mt and highlights that metallurgical test work supports conventional processing, while further optimisation work continues.
Reasoning: The release reports a material JORC resource increase and improved confidence at Mina do Barroso, alongside supportive but still preliminary metallurgical commentary. It is positive and materially important, but not a feasibility or production milestone.
Positive factors
- JORC compliant Mineral Resource increased to 23.5Mt at 1.02% Li2O
- Measured and Indicated resource increased to 13.3Mt and now represents 58% of the total resource
- QA/QC, competent person sign-off and cut-off grade are disclosed
- Metallurgical test work indicates conventional processing can generate high-grade lithium concentrate
Negative factors
- Exploration Target remains conceptual and is not a resource
- No modifying factors were applied to the reported Mineral Resource Estimate
- Metallurgical work is ongoing and no final flowsheet is defined
Facts used in scoring: 18
Classification and evidence
JORC Compliantpositive
Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.
Why it applies: The announcement states the estimate is a JORC 2012 compliant Mineral Resource Estimate.
Evidence · text
“JORC 2012 Compliant Measured, Indicated and Inferred Mineral Resource Estimate”
QP/CP Signedpositive
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 release names Paul Payne and says the resource information is based on his work as Competent Person.
Evidence · text
“Mr Paul Payne, a Competent Person”
Cut Off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: The resource table explicitly states a 0.5% Li2O cut-off.
Evidence · table
“0.5% Li2O Cut-off”
Context: Table 3. April 2019 Mineral Resource Summary (0.5% Li2O cut-off)
QA/QC Disclosedpositive · Story-specific tag
Reported assays have a certified laboratory, actual QA/QC methods, or named QP/CP responsibility. Generic CP boilerplate, old-release references, plans and unrelated work are insufficient. Approval of a correction does not verify expressly unverified historical assays; assay accuracy is not guaranteed.
Why it applies: The release states QAQC protocols were in place and names blanks, standards and field duplicates.
Evidence · text
“QAQC protocols were in place”
Infill Drillingneutral · Story-specific tag
Confirmatory drilling to raise resource confidence, not new discovery.
Why it applies: The program is described as focused on improving the resource category and increasing confidence in the existing mining inventory.
Evidence · text
“focused on both improving the Mineral Resource Estimate category of the existing Mining Inventory”
Free Millingpositive
Simple, clean ore amenable to standard processing without oxidation.
Why it applies: The metallurgy section says conventional processing technology can generate concentrate, without refractory treatment being required.
Evidence · text
“using conventional processing technology”
Deleterious Elements Presentnegative · Story-specific tag
A source-stated penalty, refractory or recovery concern in the fact's scope. Element detection alone, including measured elements explicitly below penalty thresholds, does not trigger this tag. Respect negation and retain a separately stated concern even when another risk is explicitly absent.
Why it applies: Iron contamination in assay data is discussed and corrected for before estimation.
Evidence · text
“a large proportion of the assayed iron is due to contamination”
Apparent Width Onlynegative · Story-specific tag
A reported assay interval gives downhole or apparent length without a disclosed true width. It describes geometric uncertainty, not a measured true thickness or proof that the interval is overstated; drill orientation alone is not a true-width measurement.
Why it applies: Some mineralisation widths are described in terms of thickness and true width, but many resource tables do not carry drill orientation details; this is mainly a resource-summary release rather than a drill intercept report.
Evidence · text
“The lower portion is a steep dipping dyke, which is 15m-20m in true width”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a flotation route ("concentrate")
Multi Domain Testedpositive
Completed testwork covers multiple identified ore domains and addresses variability under DOMAIN_COVERAGE_TIERS. Multiple sample or composite identifiers from the same domain do not establish multiple domains, and a proposed programme is not completed coverage.
Why it applies: 3 distinct composites were tested

Measured Resourcepositive
A source-reported Measured Mineral Resource with sufficiently established geological continuity and quality. After the required study and Modifying Factors it may convert to a Proved/Proven or Probable Reserve; the resource classification alone is not a reserve or a demonstration of economic viability.
Why it applies: category is "measured"
Cut Off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: cutoff_grade is stated
QP/CP Signedpositive

Why it applies: reporting_standards includes jorc
Resource Updateneutral
The announcement publishes a new or revised estimate for an existing resource, with a source-backed change in tonnage, grade, classification, commodity or estimation basis. An older resource table reproduced as background to drilling or exploration is not a new resource update. A table heading or an effective date alone does not establish a revision in this announcement; compare the actual estimate and its scope with the prior disclosure.
Why it applies: the release compares against a previous estimate
PEA Supportingneutral
Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.
Why it applies: the release names the study this estimate supports
DFS Supportingneutral
Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.
Why it applies: the release names the study this estimate supports
Stale Estimatenegative
The estimate effective date exceeds the MRE_STALENESS window measured at the document event date. Preserve the actual dates; age alone does not establish non-compliance or a change in the resource.
Why it applies: effective date is 7.6 years before this release

Tags used in scoring
Indicated Resourcepositive
A source-reported Indicated Mineral Resource with sufficient geological confidence to apply Modifying Factors and evaluate economic viability. It may support conversion to a Probable Reserve after the required study; it is not itself a reserve.
Why it applies: category is "indicated"
Cut Off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: cutoff_grade is stated
QP/CP Signedpositive
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: qp_signed is true
JORC Compliantpositive
Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.
Why it applies: reporting_standards includes jorc
Resource Updateneutral
The announcement publishes a new or revised estimate for an existing resource, with a source-backed change in tonnage, grade, classification, commodity or estimation basis. An older resource table reproduced as background to drilling or exploration is not a new resource update. A table heading or an effective date alone does not establish a revision in this announcement; compare the actual estimate and its scope with the prior disclosure.
Why it applies: the release compares against a previous estimate
PEA Supportingneutral
Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.
Why it applies: the release names the study this estimate supports
DFS Supportingneutral
Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.
Why it applies: the release names the study this estimate supports
Stale Estimatenegative
The estimate effective date exceeds the MRE_STALENESS window measured at the document event date. Preserve the actual dates; age alone does not establish non-compliance or a change in the resource.
Why it applies: effective date is 7.6 years before this release

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.
