Mount Burgess Mining NL (ASX:MTB) continues to progress activities at its polymetallic Zn/Pb/Ag/Cu/V/Ge project in Western Ngamiland, Botswana- Kihabe-Nxuu project. It has now received further assays from three more of the 18 holes drilled into the Nxuu Deposit in Oct/Nov/Dec 2021. Earlier in April 2022, Mount Burgess had received assays from the first seven holes.
Notably, all holes were assayed for Zinc (Zn), Lead (Pb), Silver (Ag), Gallium (Ga), Germanium (Ge) and Vanadium (V).
Previous mineralogical test work confirmed that the host mineral for Vanadium is the oxide mineral Descloizite. In Descloizite the grade of Vanadium Pentoxide (V2O5) is 1.785 times the grade of Vanadium.
In the recent assay results, the three drill holes were all vertical. Low cuts have been applied to assay grades as follows:

Both metallurgical and mineralogical test work have been conducted in a bid to understand the specifics of the project better. Metallurgical test work conducted to date has shown that 93% Zn can be recovered on site from the oxide mineral Smithsonite, through solvent extraction and electro-winning. Besides, 81% of V2O5 can be recovered on site from the oxide mineral Descloizite, through gravity separation, followed by flotation using a hydroximate acid reagent for recovery to a concentrate.
On the other hand, mineralogical test work conducted to date has shown that Ga as well as Ge are primarily hosted in muscovite (mica). Mica in the form of flakes can be recovered by flotation to produce a mica rich concentrate, enabling the recovery of Ga and Ge on site. However, this requires confirmatory metallurgical test work.
At the Nxuu Deposit, upon receipt of assay results, Mount Burgess will engage an independent consultant to conduct a resource estimate compliant with the 2012 JORC Code. Meanwhile, an independent consultant is currently compiling a resource estimate on the Kihabe Deposit compliant with the 2012 JORC Code.
