Osisko Development Corp. Harnesses Cutting-Edge Technology for Gold Recovery
Osisko Development Corp. makes significant strides in gold recovery with the announcement of promising results from an ore sorting testing program at its Cariboo Gold Project in Central British Columbia. Utilizing advanced X-ray transmission (XRT) sorting technology on an approximately 80-tonne bulk sample of mineralized material, the company achieves a remarkable waste rejection rate between 42% and 55%, while recovering between 84% and 89% of the gold. These results align closely with the parameters laid out in the company’s 2025 Feasibility Study (FS), reflecting a well-researched and strategic approach to maximizing resource efficiency.
The recent advancements in artificial intelligence play a pivotal role in enhancing the sorting process. By enabling the assessment of the previously overlooked 6-10 mm size fraction, Osisko uncovers a waste rejection rate of 59% and a gold recovery of 95%. This represents a notable optimization opportunity, indicating that the potential for improving recovery rates is substantial. The upgrade ratio from this latest testwork, reported at 2.0-2.1, closely aligns with the FS assumption of 1.95, further validating the effectiveness of the current sorting methodologies. With 76% of the contained gold in the test sample projected to report to the fines fraction, Osisko is poised to refine its operations even further.
Previously, the company’s sorting efforts were limited to approximately 5 tonnes of drill core material, emphasizing the significance of this recent testing. The initial sorting process focused on the most x-ray responsive materials, which, while achieving high gold grades, resulted in lower overall recovery rates. As a next step, Osisko plans to conduct additional tests on an 8-tonne subsample of the promising 6-10 mm size fraction, with early results indicating the potential for continued high recovery rates. This comprehensive approach to ore sorting not only enhances gold recovery but also underscores Osisko's commitment to leveraging innovative technologies in mining operations.
In light of these developments, Osisko Development Corp. continues to demonstrate its potential as a leader in sustainable and efficient gold mining practices. The integration of advanced sorting technology and artificial intelligence not only enhances operational efficiency but also aligns with industry trends favoring more environmentally responsible mining methods. By optimizing gold recovery while minimizing waste, Osisko sets a precedent for future mining projects.
As Osisko prepares for its next phase of testing, the company remains focused on maximizing resource extraction while maintaining its commitment to sustainable practices. The advancements in ore sorting technology position Osisko Development Corp. to capitalize on emerging opportunities in the gold mining sector, ultimately driving value for stakeholders and contributing to the responsible development of natural resources.
