The above Mineral Resource estimate is the culmination of 18 months of work, first mapping

historical drilling and historic mine production in three dimensions, and the re -logging and

assaying of 50 years of stored drill core. Work was able to confirm historic assa y results for

copper, and assay silver for the first time, converting 86.5% of the global resource to Measured

and Indicated confidence level of an NI 43 -101 Mineral Resource estimate , which represents a

robust open pit and underground Mineral Resource estimate that is projected to deliver more than

20 years at planned production levels.

The updated Mineral Resource has been prepared and classified by technical consultants

Minxcon (Pty) Ltd (“Minxcon”) in accordance with the reporting guidelines as set out in National

Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) as required by the
