Odyssey Gold Delivers Recoveries Above 95% in Metallurgical Testing of Tuckanarra Ore Sample

Why It Matters

High‑grade, fast leach recoveries with minimal reagents lower operating costs and de‑risk the economics of shallow starter pits, enhancing Odyssey's valuation and attractiveness to partners.

Key Takeaways

• Gold leach recovery reached 95.9% after eight hours
• Cyanide usage low at 0.37 kg per tonne
• Lime consumption modest at 2.65 kg per tonne
• Gravity recovery contributed 18.8% of total gold

Pulse Analysis

Odyssey Gold’s recent metallurgical breakthrough at the Tuckanarra project underscores the growing importance of efficient ore processing in Australia’s gold sector. By extracting 95.9% of gold from a representative composite sample in just eight hours, the company demonstrates that weathered, shallow‑pit ore can be treated rapidly and profitably. Such high recoveries are uncommon for oxide‑dominated deposits, where leach performance often hovers in the low‑90s, and they signal a competitive edge in a market where processing margins are under pressure.

The test work also revealed exceptionally low reagent consumption—0.37 kg of cyanide and 2.65 kg of lime per tonne of ore—translating into reduced chemical costs and a smaller environmental footprint. When combined with an 18.8% gravity recovery, the overall recovery profile suggests a robust, multi‑stage extraction strategy that can maximize metal output while keeping operating expenses in check. For investors and mining partners, these metrics provide confidence that the Tuckanarra resource can be monetized at a lower cash‑cost base than many peer projects.

Strategically, the results validate Odyssey’s plan to develop shallow starter pits at the Cable deposit as a low‑risk, early‑cash‑flow generator. The company’s 80% ownership and ongoing infill drilling aim to expand the resource, while discussions with nearby processing facilities could secure a cost‑effective pathway to market. As the next phase of testing moves to deeper ore zones, the data will feed into a scoping study that could unlock additional value and attract joint‑venture partners seeking exposure to the prolific Murchison Goldfields.
