Gold deposits in Borneo: Exploration potential and environmental impacts

Discovery of high-quality gold-(copper) deposits is successively reported in the Sarawak, Sabah and Kalimantan regions of Borneo. Despite the economic significance, the extend of the Bornean gold mineralisation has never been well established. Recent discovery of extensive hydrothermal pyrite occurrence in sedimentary rocks highlights the presence of ancient hydrothermal activities in the country and thus gold prospectivity. This 2-year project (starts in May 2018) represents our first step to develop UBD into a regional hub of Economic Geology and Mineral Resource research. With an integrated approach of ore deposit geology, radiometric age dating, geochemistry, statistics and GIS spatial analysis, we aim to delineate the space-time distribution of gold mineralisation in Borneo and assess the regional/local (esp. within Brunei Darussalam) gold-forming potential. Meanwhile, we will also investigate the potential environmental impacts of Bornean gold exploration/mining activities. The project contributes to the further strengthening/diversification of the national economy on one hand, and safeguarding the nation from cross-border mining-related pollution on another.

Digital Geological Outcrop Library of Brunei Darussalam: Preserving National Oil & Gas Heritage for Future Exploration

Brunei Darussalam has world-class oil & gas resources, yet many reservoirs are mature and their oil production may have reached its peak. Similar to many oil-producing regions worldwide, future exploration success is dependent on thorough understanding of these reservoirs, via advance reservoir characterisation technique and solid geological knowledge in both local and regional scale. Analysing land-outcrops can offer key parameters (e.g. net/gross ratio, gamma ray, permeability) on similar subsurface reservoirs (often buried >2 km underground), which is the aim of this pioneering UBD-BSP collaborative study, i.e., develop geological analogues to better understand key reservoir formations in Brunei Darussalam. Using a combination of geological mapping, high-resolution 3D-outcrop imaging, and multi-disciplinary (gamma ray, rock-mechanical and portal XRF geochemical) logging, the project will generate the most-comprehensive digital library (database) for rock outcrops across the country. These data will be correlated with borehole geophysical/rock-mechanical/geochemical data to generate geological analogues, which are used to visualise the actual rock types in the boreholes. This project will enable more accurate oil & gas exploration and train young competent Bruneian professionals for the next generation, when exploration breakthrough will become increasingly more challenging.
