Geophysical Surveys at Vumba and Maitengwe
The Company has successfully completed its high-resolution geophysical survey at the Vumba Gold Project, marking an important milestone in advancing one of Botswana's underexplored greenstone belts. Geophysical surveys of this nature help to map stratigraphy and structures, delineating potential mineralized targets that are either not evident at surface, or where surface expression is too obscured by cover to identify trends. This enables more accurate drill targeting and improving the probability of exploration success.
