The Cu mineralization is hosted by Cretaceous clastic and carbonate rocks and includes both vein-type and dispersed-type ores. The vein-type ores account for >95% of the total copper reserved with a reported grade of 10 wt% Cu. Dispersed-type ores only account for <5% of the total deposit with an average copper grade of ~1 wt% Cu. Epigenetic sandstone-hosted copper deposit.
