Summary
Tudor Gold, American Creek's JV partner, has announced positive initial metallurgical results for the high-grade gold Supercell-One (SC-1) Complex at the Treaty Creek Project. Testing on SC-1C and SC-1D composites demonstrated gold flotation recoveries of up to 93% and successful whole ore POX extraction exceeding 91%. While a saleable concentrate of 33.6 g/t gold was produced, the cleaner concentrate contains deleterious elements including arsenic and antimony.
Reasoning: Initial metallurgical testing on the new SC-1 complex shows strong gold recovery via flotation and POX, though concentrate quality is impacted by penalty elements.
Positive factors
- High gold flotation recoveries (85-93%)
- Successful POX extraction (>91%)
- Saleable concentrate grade achieved (33.6 g/t Au)
- Demonstrated economic potential for a 'mine within a mine' concept
Negative factors
- Presence of deleterious elements (arsenic, antimony, bismuth, mercury) in concentrate
- Significant gold locked in sulphides (42%) requiring more complex processing
Facts used in scoring: 4
Classification and evidence
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: Testing involved flotation and cyanide leach processes.
Evidence · text
“achieving impressive recovery rates of 91-93% at the rougher stage with a primary grind of 75 microns”
POX/BIOX Routeneutral
Pressure or bio-oxidation for refractory ore — high CAPEX and OPEX.
Why it applies: Whole ore pressure oxidation (POX) was tested and performed well.
Evidence · text
“Whole ore POX performed well, yielding over 91% gold extraction”
Deleterious Elements Presentnegative · Story-specific tag
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: The cleaner concentrate contains arsenic, antimony, bismuth, and mercury.
Evidence · text
“the cleaner concentrate contains some deleterious elements such as 0.8% arsenic, 0.3% antimony, 0.005% bismuth, and 0.04% mercury”
Gravity Routeneutral
Gravity separation forms a material part of the flowsheet.
Why it applies: the document describes a gravity route ("gravity")
Single Domain Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: only one composite was tested

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.
