## 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 gravity and flotation. Locked-cycle testing on the MC1 composite demonstrated highly selective recovery with a low concentrate mass pull of 1.4%.

Reasoning: The locked-cycle test on MC1 demonstrates high recoveries for both gold and silver using a simple, conventional flowsheet with low mass pull and low impurities.

- 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: Coarse grind size \(150 um\) potential for lower OPEX

- Negative factor: Results are preliminary and laboratory-scale

- Negative factor: Lower recoveries observed in Baker tailings samples

Facts used in scoring: 7

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
