This confirmed the presence of three large carbonatite bodies at Gakara, which represent the regional source of rare earth elements (\"REE\").\n \n \n The review combined the structural information with the comprehensive mapping database accumulated by Rainbow over several years as well as the geological knowledge derived from PhD research completed in December 2019 to define a data-driven, objective appraisal of sites where REE mineralisation, in the form of vein stockworks and/or breccias, is likely to have been more intensely developed. This work has defined a total of 57 exploration targets.\n \n \n In parallel with the structural review and targeting, Rainbow has been reviewing the historical mining and exploration data to ensure that the full historical knowledge of the Gakara project is included in the next phase of exploration planning. The combination of historical data, recent structural analysis and upcoming 3D mineralisation models will be used to refine the targets for ...
