Liberty Gold Achieves High Gold Recovery Rates at Black Pine Project
Significant Gold Recovery Improvements at Black Pine
On a remarkable journey towards optimizing its gold extraction process, Liberty Gold Corp. (TSX: LGD; OTCQX: LGDTF) proudly announces the impressive outcomes from its Phase 5B metallurgical program conducted at the renowned Black Pine Oxide Gold Project in Idaho. These promising results reveal notable peaks in gold recovery rates across multiple ore bodies throughout the site.
Recently shared findings indicate an impressive average gold extraction rate of 85.2% from the Rangefront Zone and 80.5% from the Discovery Zone. With such heightened recovery levels, the project reinforces its potential for a cost-effective mining operation through a run-of-mine (ROM) heap leach processing approach.
Key Highlights of Phase 5B Testing
Consistent and Predictable Gold Extractions
The Phase 5B testing showcased a weighted average gold extraction of 81.9% at an average head grade of 0.65 parts per million (ppm) gold. Remarkably, individual composites displayed variations from 52% to as high as 94.5%. This data indicates a consistent leach performance where over 80% of the total gold extraction was achieved within just 10 days.
Robust Validation of Testing Methods
In the testing phase, correlations between direct leach coarse crush bottle roll tests and column leach experiments have proven to be highly aligned, with both tests approximating extraction rates of 78.4% and 81.9%, respectively. This relationship serves as solid validation that gold leaching at Black Pine maintains its efficacy across various crush sizes.
Emphasizing Recovery Potential Across Key Mining Phases
Focusing primarily on the prominent mining zones of Rangefront and Discovery, the Phase 5B testing provided valuable insights that upgraded feasibility recovery models, showing recovery rates that are either on par with or slightly improved compared to earlier results.
Future Directions and Ongoing Metallurgical Efforts
Liberty Gold is dedicated to finalizing its ongoing metallurgical programs to enhance gold recovery predictions and refine process design criteria, all essential inputs for an upcoming Feasibility Study slated for completion in 2026. This proactive strategy ensures that Liberty Gold can advance positively in the mining landscape.
Phase 6 and 7 Initiatives
The implementation of subsequent phases, such as Phase 6, which involves testing large-scale ROM surface bulk samples, is currently underway. Meanwhile, Phase 7 combines cut-off grade variability composites, allowing investigations into gold extraction at lower grades, reinforcing Liberty Gold's commitment to thorough resource recovery modeling.
Maximizing Potential for Environmental and Economic Benefit
Liberty Gold’s commitment to sustainable and responsible mining practices remains unwavering. By conducting extensive analysis and testing, the company aims not only for improved recovery rates but also for positive environmental impacts, fulfilling its promise to stakeholders and the community.
Quality Assurance and Oversight at Liberty Gold
All metallurgical procedures must meet the rigorous standards set by Liberty Gold, overseen by experts in the field. Notably, the work conducted at KCA Labs in Reno has been spearheaded by seasoned professionals, ensuring the highest level of integrity in data collection and result interpretation.
