- Osisko Development (ODV, Financial) achieves significant gold recovery and waste rejection in ore sorting tests for Cariboo Gold Project.
- Key results show a 2.0-2.1 upgrade ratio, surpassing the 1.95 expected in the 2025 Feasibility Study.
- Advancements in AI technology highlight potential for future optimization in processing efficiency.
Osisko Development Corp. (ODV) has reported positive findings from its latest ore sorting tests for the Cariboo Gold Project in British Columbia, Canada. The tests, conducted on an approximately 80-tonne bulk sample, have demonstrated enhanced processing efficiency with significant implications for future operations.
The testing achieved an impressive 42-55% waste rejection with 84-89% gold recovery for mid-size and oversize materials. Notably, the previously untested 6-10mm size fraction showed a 59% waste rejection and 95% gold recovery. This resulted in an upgrade ratio of 2.0-2.1, exceeding the assumption of 1.95 set out in the 2025 Feasibility Study.
The ore sorting program utilized TOMRA's AI-enabled XRT technology, representing a substantial increase in data volume compared to previous tests conducted on smaller samples of around 5 tonnes. Approximately 76% of the contained gold was reported in the fines fraction, hinting at potential optimization opportunities in future engineering phases.
The successful test reinforces the economic model of the Cariboo Gold Project and suggests that further optimization can substantially enhance gold recovery rates. Additionally, the continued implementation of advanced AI technologies could provide further efficiencies, enhancing the project's viability and economic return.
