Slide 6: Project Development Progress
Project Development Progress Since being granted Prospecting Licence PL43/2016, project development has progressed. However, during the COVID pandemic, in-field operations were delayed due to restrictions imposed by both Botswana and Australia. From April 2020 to March 2022 travelling from Western A
Slide 7: Work conducted during COVID
Work conducted during COVID Restrictions during the COVID pandemic, impacting in-field operations, allowed for time to be diverted to in-depth, in-house assessment of both the main Kihabe and Nxuu, primarily Zinc, Lead, Silver, SEDEX Deposits, to determine the best way forward for the project. As th
