NXUU POLYMETALLIC DEPOSIT ASSAY RESULTS

On 8 April 2022 the Company released assays received from seven holes of the seventeen holes drilled into the Nxuu Deposit. The Company has now assembled the assay data to show the following:

• • The mineralised intersections and grades for each drill hole for Zinc (Zn), Lead (Pb), Silver (Ag), Vanadium Pentoxide (V2O5), Germanium (Ge), Gallium (Ga) are shown on Annexure A.

• • The Nxuu Deposit Drill Hole Map (Ref Figure 1), showing the location of all holes drilled to date including the seven recently drilled holes in red with their mineralised intersections and grades, alongside drill holes previously reported.

• • Individual Drill Hole Sections showing the relevant drill hole numbers in red, with their mineralised intersections and grades alongside neighbouring drill holes previously reported (Ref Figures 2 to 5)

These new assay results support and/or improve the tenor and extent of the assay results of previous resource drilling campaigns.
