Surveys on Gem minerals in Sri Lanka

Project of Exploration and Assessment of Gem deposits in Sri Lanka


This is a cabinet approved project and is being conducted with the objective of exploration and assessment of known gem deposits in the country, discovering unknown gem deposits with significant potentials and preparation of detailed inventories of the gem occurrences in the country with sufficient data to guide development of investment profiles.

Under this project, all divisional secretariat areas of potentially gem bearing districts are to be covered and separate gem information systems with gem potential maps are to be compiled. Field exploration, sampling, sample processing (sieve analysis, magnetic separation etc.), mineralogical analysis, geochemical analysis and GIS analysis are incorporated to the methodology.
