Omai Gold Reports Positive Metallurgical Testwork at its Omai Project with Gold Recoveries from 93% to 95%

Omai Gold’s clean metallurgy results support its upcoming Q3 preliminary economic assessment for its Guyana project.

Executive Summary
  • Omai Gold released Phase 1 metallurgical testwork results for its Wenot and Gilt deposits.
  • Gold extraction rates range from 93% to 95% using conventional carbon-in-leach (CIL) processing.
  • Optimal processing parameters identified: 32-hour retention time and a grind size of 80% passing 75 microns.
  • Mineralogy is clean, lacking deleterious components such as organic carbon, tellurides, or antimony.
  • Results validate historical recoveries (>92%) and support a Preliminary Economic Assessment (PEA) targeting 20,000–25,000 tonnes per day throughput.
  • The PEA is expected in 4–6 weeks, incorporating conventional milling/CIL processing and updated resource estimates.
Material Impact
  • The metallurgical results are a standard, expected milestone in the pre-feasibility pathway and align with prior management guidance.
  • They confirm that the expanded resource base (2.5 Moz Indicated, 5.5 Moz Inferred as of April 2026) can be processed efficiently with conventional methods.
  • No new resource growth, financing, or operational changes were announced; the update is incremental and serves to de-risk the upcoming PEA.
  • The clean mineralogy reduces technical risk, but does not alter the fundamental valuation or timeline materially.
