Osisko Development Unveils Positive Bulk Tonnage Results for Cariboo
Osisko Development Corp. (NYSE: ODV, TSXV: ODV) recently shared positive results regarding ore sorting tests at their Cariboo Gold Project. This innovative project, spanning over 186,740 hectares, showcases the potential for significant gold recovery, enhancing the prospects of the company’s mining endeavors in Canada.
Highlights of the Ore Sorting Test Program
The highlights from the test program are promising, particularly with respect to the X-ray transmission (XRT) ore sorter. Key outcomes included:
- Success with XRT Technology: A sample weighing approximately 80 tonnes underwent successful sorting, achieving a waste rejection rate of 42-55% alongside commendable gold recovery rates ranging between 84-89%.
- Innovative Size Fraction Results: The previously unassessed 6–10 mm particle size now demonstrates a significant opportunity, yielding a 59% waste rejection rate and achieving impressive gold recovery at 92%.
- Enhanced Data Quality: The recent findings build on a larger dataset compared to prior projects, where testing was primarily conducted on smaller sample sizes from drill core.
- Flow Optimization Considerations: Results from the sorting are expected to play a pivotal role in optimizing the ore processing flowsheet, enhancing future recoveries.
Understanding the Testing Process
The conducted program was managed in collaboration with the Saskatchewan Research Council (SRC), utilizing advanced sorting technology from TOMRA. The methodology included segregation of material into various size fractions—fines, mid-size, and oversize—facilitating comprehensive analysis.
Methodologies That Deliver
- Testing in Phases: The test strategy employed a cascade approach, systematically altering sorter settings to balance mass pull and recovery levels effectively.
- AI Integration: Recent advancements in AI technology executed by TOMRA improved material assessment, allowing for optimized sorting strategies based on size and density.
The combination of large sample sizes and advanced methodologies provides a clearer picture of the ore's characteristics, enhancing the accuracy of predictions regarding gold recovery rates.
Next Steps for Osisko Development
The results reveal a need for further investigation into optimizing the Cariboo project's operational efficiencies. Future assessments will consider flow sheet adjustments and variability studies to ensure robust recovery strategies are in place.
Commitment to Quality Control
Osisko Development maintains a strict quality assurance and control process throughout testing, with analyses performed on each size fraction to guarantee precision and reliability in results.
