The known deposits in the Bau Goldfield can be characterized by four distinctive gold mineralisation styles that exhibit both lateral and vertical geochemical and mineralogical zonation with respect to the Bau Trend intrusives. In general these styles are:
• Sediment Rock-Hosted Disseminated Gold Deposits, e.g. Jugan; Bukit Sarin;
• Silica replacement (jasperoid) and open space siliceous breccias, e.g. Tai Parit; Bukit Young Pit, Bekajang;
• Mangano-calcite-quartz veins, e.g. Tai Ton; Pejiru, Kapor;
• Magmatic – Hydrothermal porphyry related deposits with/without calc-silicate skarn, e.g. Sirenggok, Sey Seng, Ropih, Arong Bakit, Juala West.
Sirenggok
The Sirenggok deposit lies approximately 1.5km NE of Bau Township. The current resource modelling has outlined an Inferred Resource of 8.346 million tonnes at 1.14 g/t Au for 307,000 ounces at a lower cut-off of 0.5g/t Au.
Jugan
The Jugan Deposit is centred on Jugan Hill, approximately 7 km NE of Bau, within a kilometre of the Bau-Kuching Road. The current measured and indicated resource modelled stands at 17.91 million tonnes at 1.51 g/t Au for 870,500 ounces gold. Inferred resources are 1.77 million tonnes at 1.57 g/t Au for 89,800 ounces gold.
Pejiru Sector
The Pejiru Sector between 5 km and 8 km SW of Bau, comprises four deposits that have been modelled. These are the Pejiru-Bogag, Pejiru Extension, Kapor and Boring deposits. As a result of the current reso ........
