# Magna Terra Samples High-Grade Copper Assaying up to 8.17% Cu at the Restigouche Trend, Rocky Brook Project, New Brunswick Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/magna-terra-samples-high-grade-copper-assaying-up-to-8-17-cu-at-the-restigouche--57179b01-1c56-4483-b82b-53ef760654bf Original source: https://money.tmx.com/en/quote/MTT/news/5856187314042705/magna-terra-samples-high-grade-copper-assaying-up-to-8-17-cu-at-the-restigouche- Publisher: tmx Original announcement: 2026-01-13T13:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Magna Terra Minerals Inc. - Ticker: MTT - Exchange: TSX - Region: New Brunswick - Primary commodity: Copper - Secondary commodities: Zinc, Lead, Gold, Cobalt - Document categories: Drill results, Other - Extracted: 2026-08-25 22:59:13 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Magna Terra Minerals reported high-grade copper assays up to 8.17% Cu and zinc up to 1.57% Zn from rock grab samples at the Restigouche Trend. The prospecting program also identified potential new VMS and sediment-hosted copper targets within the Rocky Brook Project in New Brunswick. Reasoning: Strong high-grade copper and zinc grab samples from a regional prospecting program, though sample type \(grab\) limits geological confidence. - Positive factor: High-grade copper intercepts \(8.17% Cu\) - Positive factor: Discovery of new VMS prospectivity - Positive factor: Proximity to existing infrastructure \(Caribou Mill Complex\) - Negative factor: Results are from grab samples \(selective/not representative\) - Negative factor: Historical drill results mentioned without new assay validation Facts used in scoring: 5 ## Classification and evidence **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: Results are from prospecting/grab samples near the past-producing Restigouche Mine. Evidence · text > to the past-producing Restigouche massive sulphide deposit **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: While a lab \(ALS\) is named, specific QA/QC protocols \(blanks, standards, duplicates\) are not detailed for these specific grab samples. Evidence · text > All rock samples collected were submitted to ALS Canada Ltd. ## Extracted facts Stored fact records: 5.

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.
