# Masivo Confirms High-Grade Gold-Copper Mineralization Beneath Historic Boston Mine with 45 ft. of 3.25% Cu Equivalent Including 5ft. of 6.39% Cu equivalent Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/masivo-confirms-high-grade-gold-copper-mineralization-beneath-historic-boston-mi--ce91d0a1-e7eb-4f72-b8ed-5464b6a933b2 Original source: https://money.tmx.com/en/quote/MASS/news/6540707436197211/masivo-confirms-high-grade-gold-copper-mineralization-beneath-historic-boston-mi Publisher: tmx Original announcement: 2026-07-15T14:38:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Masivo Silver Corp. - Ticker: MASS - Exchange: TSX - Region: Nevada - Primary commodity: Copper - Secondary commodities: Gold, Silver - Document categories: Drill results, Other - Extracted: 2026-08-21 22:31:56 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Masivo Silver Corp. has reported high-grade gold-copper mineralization at the Boston Mine Project in Nevada, including a 5 ft intercept of 6.39% CuEq. The results confirm the continuation of mineralization beneath historic underground workings and demonstrate successful step-out drilling along the trend. Reasoning: Strong high-grade copper-equivalent intercepts in step-out drilling confirm the extension of mineralization beneath historic workings. - Positive factor: High-grade copper equivalent intercepts - Positive factor: Step-out drilling success - Positive factor: Continuation of mineralization beneath historic workings - Negative factor: Historical data not independently verified Facts used in scoring: 9 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Significant intercepts in step out drilling along the trend of underground development. Evidence · text > significant intercepts in step out drilling along the trend of underground development **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 includes detailed CuEq calculation assumptions and mentions a Qualified Person \(Brian Brewer, PGeo\). Evidence · text > Brian Brewer, PGeo, is Masivo Silver's qualified person ## Extracted facts Stored fact records: 9.

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.
