# IMC Rare Earths Discovers New High-Grade, Near-Surface Terbium Zone Beyond Existing 1.1 Billion Tonne Resource at Block H, Itarantim Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/imc-rare-earths-discovers-new-high-grade-near-surface-terbium-zone-beyond-existi--fa15124a-89a7-4726-95c6-85a7aee0428e Original source: https://www.juniorminingnetwork.com/junior-miner-news/press-releases/3537-nysemkt/imc/212600-imc-rare-earths-discovers-new-high-grade-near-surface-terbium-zone-beyond-existing-1-1-billion-tonne-resource-at-block-h-itarantim.html Publisher: jmn Original announcement: 2026-10-08T21:39:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-08T12:27:53.344Z Atlas analysis updated: 2026-10-08T12:27:53.344Z - Company: IMC Rare Earths Ltd - Ticker: IMC - Exchange: NYSE American - Region: Brazil - Primary commodity: Rare earth elements - Secondary commodities: Terbium, Dysprosium, Yttrium - Document categories: Drill results, Other - Extracted: 2026-10-08 12:27:54 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary IMC Rare Earths has announced a new high-grade, near-surface terbium-rich discovery at Block H of its Itarantim project in Brazil. The discovery, located outside the company's existing 1.1 billion tonne resource, features mineralization starting just two meters below the surface with strong initial leach recoveries. Reasoning: Discovery of a high-grade terbium-rich zone at Block H, which is entirely outside the existing 1.1 billion tonne resource, represents significant growth potential. - Positive factor: High-grade terbium discovery - Positive factor: Near-surface mineralization - Positive factor: Located outside existing resource - Positive factor: Strong initial leach recoveries - Negative factor: Single hole discovery - Negative factor: Conceptual nature of exploration target Facts used in scoring: 10 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Block H lies outside the existing 1.1 billion tonne Mineral Resource and has not previously been drill tested. Evidence · text > Block H lies outside the Company's existing 1.1 billion tonne Mineral Resource **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions blanks, field duplicates, and certified reference materials. Evidence · text > Sample batches include blanks, field duplicates and certified reference materials ## Extracted facts Stored fact records: 10. Some facts used in scoring do not have a stored record. ## Drill Results (10) ### AD-00555 [Link to this fact](https://atlas-staging.minestarters.com/news/imc-rare-earths-discovers-new-high-grade-near-surface-terbium-zone-beyond-existi--fa15124a-89a7-4726-95c6-85a7aee0428e#fact-drill-facts-0) Itarantim · rare earth elements #### Identity - Hole ID: AD-00555 - Project: Itarantim - Commodity: rare earth elements - Region: brazil - Reported Region: brazil - Ticker: IMC #### Geometry - Grade: 5695 - Grade Unit: ppm - Intercept: 7 m - From: 2 m - To: 9 m - Hole Depth: 16 m - Intercept Depth: 2 m #### Classification - Deposit Type: other - Program: exploration - Sample Type: drill - Group ID: AD-00555:2-9 - Mining Method: unknown #### Location - Location: Block H - Loc.

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.
