Latest from Rio work on Solwesii -
Rio Tinto’s 2020 exploration work focused on strengthening their geological understanding of the Solwezi
Licences. Emphasis was placed on identifying and modelling the geology of the Kazhiba Dome which
underlies the 22 Zone, where an overturned Upper Plate and upright facing Lower Plate are separated by a
mafic breccia. This geology appears similar to what is observed at the Kansanshi Mine. The work completed
during this program included:
• The reanalysis of previous air core drill samples over the Kazhiba Dome and adjacent areas;
• 129 air core drill holes drilled on a 500 metre x 500 metre grid over the entire Kazhiba Dome;
• Six stratigraphic diamond holes, totalling 2,060 metres, designed to test the Lower Plate of the
Kazhiba Dome for mineralisation;
• The air core programme which included 29 air core holes tracking an audio-frequency
magnetotelluric geophysical line towards Basement and tested a mineral occurrence at the
Gameno (formerly Kifubwe) Prospect;
• The reanalysis of previous soil samples; and
• A 250 metre x 250 metre infill geochemical soil sampling grid.
Rio Tinto’s 2021 exploration program has been completed and the Company is expecting complete results
and interpretation by late May.
