# TDG Announces Positive Results from Ongoing Metallurgical Test Work - Conventional Processing Achieves >90% Gold and Silver Recoveries At Shasta, Toodoggone District Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/tdg-announces-positive-results-from-ongoing-metallurgical-test-work-conventional--c32c2bb1-27b6-41cb-a186-47cc65e4e941 Original source: https://money.tmx.com/en/quote/TDG/news/6959598297832111/tdg-announces-positive-results-from-ongoing-metallurgical-test-work-conventional Publisher: tmx Original announcement: 2026-06-17T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: TDG Gold Corp. - Ticker: TDG - Exchange: TSX - Region: British Columbia - Primary commodity: Gold - Secondary commodities: Silver, Sulfur - Document categories: Metallurgy - Extracted: 2026-08-20 21:48:35 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary TDG Gold Corp. has reported positive metallurgical test results for the Shasta Gold-Silver Project, achieving average gold recoveries of 92.4% and silver recoveries of 90.3% using a conventional gravity and flotation circuit. Locked-cycle testing on master composite MC1 confirmed over 91% recovery for both metals with a highly selective 1.4% mass pull. The results support the selection of a simple, low-cost processing route for the project's Preliminary Economic Assessment. Reasoning: The announcement reports strong, consistent recoveries for gold and silver using a conventional flowsheet, which significantly de-risks the project's metallurgical profile for the upcoming PEA. - Positive factor: High gold and silver recoveries \(>90%\) - Positive factor: Conventional processing route \(gravity + flotation\) - Positive factor: Low concentrate mass pull \(1.4%\) - Positive factor: Low impurity levels \(arsenic/copper\) - Positive factor: Locked-cycle testing confirms results - Negative factor: Results are preliminary and laboratory-scale - Negative factor: Variability noted in Baker tailings and METS prospect Facts used in scoring: 8 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route.

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.
