# Resouro Files Technical Report for Tiros Project Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/resouro-files-technical-report-for-tiros-project--b0641a85-a88c-49c2-8f88-70561bcaa519 Original source: https://www.globenewswire.com/news-release/2026/07/30/3335706/0/en/resouro-files-technical-report-for-tiros-project.html Publisher: globenewswire Original announcement: 2026-07-30T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Resouro Strategic Metals Inc. - Ticker: RSM - Exchange: Unavailable - Region: Minas Gerais, Brazil - Primary commodity: Titanium - Secondary commodities: Rare earths - Document categories: Resource update, Other - Extracted: 2026-08-20 19:20:06 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Resouro Strategic Metals has filed a NI 43-101 compliant technical report and Preliminary Economic Assessment \(PEA\) for the Tiros Project in Brazil. The report supports a staged development strategy starting with a high-grade operation and outlines a massive 1.4 billion tonne Measured and Indicated resource. Reasoning: The filing of a NI 43-101 compliant technical report supporting a PEA for a large-scale titanium and rare earths project with strong economics is a significant de-risking and formalization milestone. - Positive factor: Strong project economics \(NPV US$714.9M, IRR 44.2%\) - Positive factor: Large scale resource \(1.4 Bt M+I\) - Positive factor: High-grade starter option identified - Positive factor: NI 43-101 compliant technical report filed - Negative factor: PEA is preliminary in nature - Negative factor: High sensitivity to reagent costs - Negative factor: Inferred resources are speculative Facts used in scoring: 18 ## Classification and evidence **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 explicitly stated to be NI 43-101 compliant. Evidence · text > NI 43-101 compliant report supports previously announced PEA results **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The project contains significant Inferred resources which are considered speculative. Evidence · text > It includes Inferred Mineral Resources that are considered too speculative geologically **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: Multiple Qualified Persons and Competent Persons are named and their responsibilities are detailed. Evidence · text > The announcement has been reviewed and approved by the relevant Qualified Persons under NI 43-101 and Competent Persons under the JORC Code ## Extracted facts Stored fact records: 18.

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.
