# Compass Reports Strong Gold Recoveries from Recent Metallurgical Testing at Massala Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/compass-reports-strong-gold-recoveries-from-recent-metallurgical-testing-at-mass--4175010f-6dcb-451b-b3e2-f642df06792a Original source: https://money.tmx.com/en/quote/CVB/news/6499604508799748/compass-reports-strong-gold-recoveries-from-recent-metallurgical-testing-at-mass Publisher: tmx Original announcement: 2026-06-01T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Compass Gold Corp. - Ticker: CVB - Exchange: TSX - Region: Southern Mali - Primary commodity: Gold - Secondary commodities: Mercury, Lead, Antimony, Tellurium, Bismuth, Arsenic - Document categories: Metallurgy, Drill results, Other - Extracted: 2026-09-15 18:45:57 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Compass Gold Corp. reported robust metallurgical results at the Massala prospect, including a 95.3% gold recovery via bottle roll leaching on sample MA-5. The company also announced the completion of Phase 1 resource definition drilling, which included high-grade visible gold intercepts. Reasoning: Strong metallurgical recoveries and completion of a major drilling phase significantly de-risk the project's path to production. - Positive factor: High gold recovery \(95.3%\) achieved via bottle roll leaching - Positive factor: Gold characterized as free-milling and straightforward to process - Positive factor: Completion of Phase 1 drilling program on schedule - Positive factor: Presence of high-grade visible gold \(>100 g/t Au\) - Negative factor: Presence of potential deleterious elements \(arsenic, mercury, etc.\) noted Facts used in scoring: 3 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: 95.3% gold recovery achieved via bottle roll leaching is exceptional. Evidence · text > A final gold recovery of 95.3% was achieved on sample MA-5 **Free Milling** Polarity: positive Definition: Simple, clean ore amenable to standard processing without oxidation. Why it applies: Gold is characterized as free-milling, suggesting simple processing. Evidence · text > gold content is characterized as moderate-to-fine-grained and free-milling **Deleterious Elements Present** Polarity: negative Definition: A source-stated penalty, refractory or recovery concern in the fact's scope. Element detection alone, including measured elements explicitly below penalty thresholds, does not trigger this tag. Respect negation and retain a separately stated concern even when another risk is explicitly absent. Why it applies: Release mentions potential deleterious elements like mercury, lead, and arsenic. Evidence · text > All samples contain low concentrations of potential deleterious elements \(e.g., mercury, lead, antimony, tellurium, and bismuth\) **Gravity Route** Polarity: neutral Definition: Gravity separation forms a material part of the flowsheet. Why it applies: the document describes a gravity route \("gravity"\) **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 2 distinct composites were tested ## Extracted facts Stored fact records: 3.

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.
