Episode notes
High Gold Recovery From First Tests
- Initial metallurgical tests returned ~95% gold recovery from three underground bulk samples.
- That high recovery came without any optimization, signaling strong gold processing potential.
Use Gravity First To Boost Recovery
- Run gravity concentration before leaching to boost overall gold recovery.
- Remove gravity concentrate early, then leach tails to potentially raise the combined recovery above 95%.
Silver Recoveries Are Variable
- Silver recoveries were variable, ranging ~41% to 76% across samples.
- Pinnacle will run mineralogical tests to determine how silver occurs and which process (e.g., flotation) could improve recoveries.
