Abstract :
The study focuses on the estimation of the incidence, distribution, and potential of gold deposits in Kelani River
and Seethawaka Oya, and their likely gold-bearing zones in catchment areas around them. It is significant that because of
economic significance and application in sustainable natural resource management, the occurrence of gold in the region is
best interpreted for future prospecting. To ensure an integrated appraisal, the study applied a multidisciplinary approach
through the combination of geological, geochemical, and remote sensing techniques. Field activities were thorough with
sampling and laboratory analysis of river sediments and soil to determine gold content and associated elements. Laboratory
testing facilitated quantification of concentrations as well as determination of geochemical signatures for mineralization.
Application of GIS and remote sensing methods played an important role in mapping the areas of mineralization, bringing
aboard the big picture regarding probable gold deposits. The findings supported the presence of gold deposits in the
riverbeds, which was in agreement with previous history of gold discoveries in the area. The research also reported a number
of potential zones in the catchment areas to be further explored. The findings are of great significance to the understanding
of regional mineral wealth and provide important information for future mining prospects and utilization of resources.
Besides, the research advocates for careful exploration and management of resources to provide that any expected economic
benefits match environmental conservation and sustainable development targets. The conclusions of the study provide a
solid foundation for the future gold exploration projects, in order to guide policymakers, geologists, and investors in taking
effective decisions.
