Mount Burgess Mining N.L. advised that it has received and assembled assay results from the final four of eighteen diamond core holes drilled at the Company's 100% owned Nxuu Deposit in Western Ngamiland, Botswana, from October to December 2021. All holes from this drilling programme (shown in red on Figure 1 - Drill Hole Map) were assayed for Zinc, Lead, Silver, Vanadium, Gallium and Germanium. Previous results from seven of the holes were announced on 8 April 2022, three of the holes on 16 June 2022 and four of the holes on 11 July 2022.

Mineralisation at the Nxuu Deposit occurs within a shallow and totally oxidised Quartz Wacke, situated within a Dolostone basin, beneath Kalahari sand cover. Assay results received from the last four 2021 Nxuu Deposit drill holes confirm: Significant lengths of up to 34.33m of continuous Ga mineralisation occur on the outer eastern perimeters, signifying potential for further extensions of Ga mineralisation. Significant lengths of up to 22m Zn, 34m Ge and 23m V2O5 occur within the main mineralised zone.

In depth analysis of data confirms: Mineralisation occurs within a shallow oxidised Quartz Wacke formation situated in a Dolostone basin beneath Kalahari sand cover. Forty holes drilled to date and assayed for Zn/Pb/Ag/V/Ge/Ga contain combined mineralisation of about 1,198.8m, representing 81.7% of approximately 1,467m of the drilled oxidised Quartz Wacke. Seven holes drilled to date only assayed for Zn/Pb/Ag/V contain combined mineralisation of about 110.7m, representing 48% of approximately 231m of the drilled oxidised Quartz Wacke.

Forward planning: Independent work can now commence to estimate an initial mineral resource for the Nxuu Deposit, compliant with the 2012 JORC Code. Independent work is in progress to estimate a mineral resource for the Kihabe Deposit, compliant with the 2012 JORC Code.
