Osisko Development Corp. achieves promising results in bulk tonnage ore sorting testwork

Osisko Development Corp. conducted X-ray transmission ore sorter testwork on a ~80 tonne sample from the Cariboo Gold Project, achieving 42-55% waste rejection and 84-89% gold recovery. Results show a potential opportunity in sorting the 6-10 mm size fraction, with an upgrade ratio of 2.0-2.1, consistent with 2025 FS parameters.

Positive outcomes from the testing program were conducted at the Cariboo Gold Project in British Columbia, Canada. The testwork utilized an XRT sensor to assess various particle sizes and showed promising gold recovery rates and waste rejection percentages. The program was significantly larger than previous efforts and may lead to flowsheet optimization.

The ore sorting testwork was conducted at the Saskatchewan Research Council with support from TOMRA Sorting. Different size fractions were tested, including previously unassessed material. Recent advancements in AI software allowed for more accurate testing, leading to potential opportunities for future optimization in the processing flowsheet.

The Cariboo Gold Project, a permitted feasibility-stage project in British Columbia, boasts significant mineral reserves and resources. The project has been granted key permits, solidifying its shovel-ready status. The Company is focused on becoming an intermediate gold producer by advancing its flagship project while minimizing development risks and growing mineral resources.
