A four-year program planned for WAXI Stage 3 commenced in September 2014. After canvassing existing and potential new sponsors, a program for Stage 3 was designed that will further enhance the exploration potential of the Leo-Man Shield through an integrated program of research and data gathering into its “anatomy’. The initiative covers the whole of the Leo-Man Shield, which includes the following countries: Burkina Faso, Guinea, Ivory Coast, Liberia, Ghana, Mali, Senegal, Niger, Sierra Leone and Togo. Key motivations for undertaking this initiative are to assist exploration companies in focusing their activities in areas of maximum prospectivity and to help local Geological Surveys in the region in their role of providing pre-competitive data and information.
HIGHLIGHTS/DELIVERABLES/VALUE ADDITIONS Achievements from the WAXI program to date have included: • An improved knowledge of the tectonic history and metallogeny of the craton • 3D models of mineralised terranes and of the entire West African Craton • The assembly of a 250Gb craton-wide GIS product bringing combining over 200 distinct themes, 50 of which are unique to the WAXI project • New harmonised 1:500 000 integrated geophysical and geological maps of key zones • New models for regolith and landform evolution • 500 km Magnetotelluric Survey down to 300 km across southern Burkina Faso and Northern Ghana • Over 100 new geochronology ages • An Atlas of West African Ore Deposits • The founding of a collaborative international research and training network in the Stage 1 WAXI dedicated to better understanding the West African Craton • Delivering 15 training courses covering Geophysics, Geochemistry, Field and Mine Mapping, Exploration Targeting and Research Management.
