Liberty Gold Validates Gold Recovery Assumptions in Black Pine Metallurgical Tests
Event summary
- Liberty Gold completed Phase 6 metallurgical testing on Black Pine Oxide Gold Project, validating gold leach recoveries for run-of-mine (ROM) sized material.
- Bulk column tests confirmed modeled gold recoveries, with average extraction of 72.4% for ROM-sized samples.
- Rangefront Ppos sample outperformed modeled recoveries by over 13%, potentially increasing the value of this unit.
- Tests demonstrated rapid leach kinetics, with 90% of gold extraction achieved within 36 days for most samples.
- Cyanide and lime consumption values aligned with commercial-scale performance, de-risking operating cost estimates.
The big picture
Liberty Gold's successful validation of gold recovery assumptions through bulk column testing strengthens the economic viability of its Black Pine project. This technical de-risking comes at a crucial stage as the company moves toward construction decisions, positioning it favorably in the competitive landscape of oxide gold projects. The results underscore the importance of detailed metallurgical work in heap leach operations, potentially setting a new standard for similar projects in the Great Basin region.
