Genesis of the hydrothermal gold deposits in the Canan

The Canan area (Honduras) is characterized by a goldbearing ore deposit that is associated with quartzveined shear zones Gold mineralization occurs in lowto mediumgrade metamorphic hostrocks (graphitic and sericitic schists) Hydrothermal fluids, which are associated with the emplacement of CretaceousTertiary granodioritic intrusions, are responsible for the formation ofThe crushed ore is then transferred to the Coarse Ore Stockpile (COS), which has a holding capacity of up to 500,000 tonnes of material for downstream processing Ore material from the COS is reclaimed by conveyor into a parallel train of two HighPressure Grinding Rolls (HPGR’s), which grind the ore to a size of 4 mm or smallerMineralisation and Ore Type – Karara Mining
