US EditionCORRECTION - Osisko Development Announces Positive Bulk Tonnage Ore Sorting Results for the Cariboo Gold Project - Osisko Development (NYSE:ODV)
CARIBOO, BRITISH COLUMBIA, JUL 7 – Ore sorting testwork shows 84-92% gold recovery and 42-59% waste rejection, supporting 2025 feasibility study assumptions and enabling potential future process optimization.
- On July 7, 2025, Osisko Development announced positive bulk ore sorting results consistent with 2025 feasibility study assumptions at the Cariboo Gold Project.
- Following late 2024 permits, SRC and TOMRA began bulk ore sorting tests using a TOMRA COM 1200 Tertiary XRT machine at SRC’s Saskatoon facility, validating project readiness.
- Osisko Development's ore sorting achieved 84–89% gold recovery on major fractions and 92% on untested smaller sizes, supporting feasibility assumptions.
- Positive ore sorting results confirmed consistency with 2025 FS assumptions and highlighted potential for further optimization of the untested 6–10 mm fraction.
- Osisko Development's planned flowsheet optimization and variability study aim to refine assumptions, with legal reviews unlikely to delay project progress, based on recent positive testwork results.
