The report also highlights a significant Mineral Resource update, increasing the Inferred resource to 52.2Mt of graphite. Reasoning: The announcement of a PEA with strong economics and a significant resource expansion is highly material for a developer. - Positive factor: Significant increase in Mineral Resource tonnage \(2.4x\) - Positive factor: Strong economic indicators: 34.8% Pre-tax IRR and US$2.4B Pre-tax NPV - Positive factor: Vertically integrated strategy from mine to battery-grade anode material - Positive factor: High metallurgical recoveries \(90% average\) - Positive factor: Strategic location in US EV/defense corridor - Negative factor: Resource is 100% Inferred category - Negative factor: PEA is a low-confidence study level \(Class 5 estimate\) - Negative factor: Environmental risks noted regarding tailings \(PAG\) Facts used in scoring: 2 ## Classification and evidence **All Inferred** Polarity: negative Definition: 100% of resource is Inferred category — very early stage, no engineering confidence. Why it applies: The updated Mineral Resource estimate is stated as 100% Inferred. Evidence · text > increase to 52.2Mt from 22Mt of Inferred pit-constrained Mineral Resources **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The technical report is prepared in accordance with NI 43-101 requirements. Evidence · text > prepared in accordance with the requirements set forth by Canadian NI 43-101 **Tonnage Growth** Polarity: positive Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved. Why it applies: Mineral Resource tonnage increased from 22Mt to 52.2Mt. Evidence · text > increase to 52.2Mt from 22Mt **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a mill\_cil route \("concentrator"\) **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: 2.

Cannot support economic studies alone. Why it applies: category is "inferred" **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: cutoff\_grade is stated **QP/CP Signed** Polarity: positive 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: qp\_signed is true **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: reporting\_standards includes ni\_43\_101 **No Contained Metal** Polarity: negative Definition: Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting. Why it applies: contained\_metal was not reported **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: the release compares against a previous estimate **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: the release names the study this estimate supports ## Metallurgical Results (1) ### flotation [Link to this fact](https://atlas-staging.minestarters.com/news/south-star-announces-filing-of-technical-report-with-significant-increase-in-min--fb3d491e-65fb-494f-b4e4-c952a6fc9057#fact-metallurgical-facts-1) BamaStar · graphite #### Identity - Project: BamaStar - Commodity: graphite - Region: usa - Reported Region: Alabama, U.S.A. - Ticker: STS #### Test Work - Program Status: preliminary - Test Type: flotation - Processing Route: flotation - Sample: BamaStar Mine and Concentrator Plant #### Recovery - Recovery: 90 % - Recovery Basis: actual\_test - Head Grade: 2.11 - Head Grade Unit: % Cg #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2024-11-14T00:00:00.000Z Reasoning: Strong metallurgical recovery reported for the concentrator circuit. - Positive factor: High average recovery of 90% Evidence · text > average recovery of 90% #### Tags used in scoring **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: the release describes a byproduct credit ## 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.
