Metallurgical Testwork OSINO RESOURCES Multiple types and phases of met testwork were completed by Maelwgyn and OMC (overseen by Lycopodium) over the last 12 months: 4 Phases of leach testwork: Grind size (80% passing 75 vs 53 microns) Leach retention time (48 vs 24 hours) Pre-oxidization ➤ Medium to hard mineralized material amenable to standard 3-stage crushing & ball milling ➤ Comminution circuit power consumption 17.1kWh/t for 80% passing 53μm grind ➤ Initial gravity recovery test results were promising but not definitive.
