Summary
Sitka Gold reported successful initial metallurgical testing at the Rhosgobel deposit, achieving 94.3% gold recovery via cyanidation and 84.7% tungsten recovery via flotation. The results suggest tungsten could serve as a valuable byproduct for the project.
Reasoning: Initial metallurgical testing shows high recoveries for both primary gold and tungsten using conventional methods.
Positive factors
- High gold recovery
- Strong tungsten byproduct potential
- Conventional processing route
Facts used in scoring: 2
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: Gold recovery of 94.3% is in the exceptional band for mill/CIL routes.
Evidence · text
“Gold recovery averaging 94.3%”
Byproduct Commodityneutral
The tested commodity is a byproduct rather than the primary economic driver.
Why it applies: Tungsten is identified as a potential valuable byproduct.
Evidence · text
“tungsten could be a valuable by-product”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: Testing utilized cyanidation leaching and flotation.
Evidence · text
“utilizing conventional whole ore cyanidation leaching”

Reasoning: 84.7% recovery is strong for tungsten flotation and achieved with a very low mass pull.
Positive factors
- Strong tungsten recovery
- Low mass pull
Evidence · text
“tungsten recovery of 84.7% in rougher concentrate using conventional flotation with a very low mass pull of less than 1%”
How Atlas produces this analysis
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.
