Twenty-five White Channel gravel samples were processed to estimate gold content, with levels ranging from <0.03 to 0.33 g/t. The Government of Yukon conducted metallurgical tests, including bottle rolls and column tests with cyanide, yielding maximum gold extractions greater than 65%. Sampling challenges were noted due to the low grade and discrete nature of gold particles.
Use Cases
- Evaluate gold extraction viability via heap leaching based on cyanide bottle roll and column test results
- Analyze pre-concentration effectiveness based on screening at 4 mesh upgrade rates
- Assess gravity concentration potential based on reported low recovery rates
- Model sampling challenges for low-grade materials based on described 'nugget' effect
Strengths
- Gold levels are quantified, ranging from <0.03 to 0.33 g/t
- Pre-concentration upgrade factor is specified as an average of 2.4 times
- Maximum gold extraction from cyanide tests is reported as greater than 65%
- Cyanide consumption is quantified as less than 1.2 kg/t of leach feed
Limitations
- Row count is unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
- Data may reflect geographic bias inherent to the Yukon region
