Analysis by Minestarters Atlas
Minestarters Atlas analysis
Summary
International Tower Hill Mines has released encouraging preliminary metallurgical results from its antimony study at the Livengood Gold Project. Initial testing on vein composites indicates that stibnite is well-liberated at a 250 micron grind and shows potential for recovery via flotation.
Reasoning: Preliminary metallurgical study shows good stibnite liberation and potential for flotation, which could unlock antimony as a byproduct.
Positive factors
- good liberation of stibnite at 250 micron grind
- potential for flotation response
- encouraging preliminary results
Negative factors
- results are very preliminary
- no economic analysis or recoverability established yet
Facts used in scoring: 8

Classification and evidence
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: The study is described as the first phase of a metallurgical study using composites, which is preliminary in nature.
Evidence · text
“The data presented here is very preliminary in nature”
Byproduct Commodityneutral
The tested commodity is a byproduct rather than the primary economic driver.
Why it applies: Antimony is being studied as a potential recovery from the gold project's stibnite veins.

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.
