- Mount Burgess Mining NL (ASX:MTB) has received promising results from mineralogical test work carried out on Kihabe Deposit’s Vanadium samples.
- The results confirm that Vanadium in the oxide zone of the Kihabe Deposit is hosted in the oxide vanadate Descloizite.
- In Descloizite, the grade of Vanadium Pentoxide (V2O5) is 1.785 times higher than the grade of Vanadium, proving that V2O5 could represent a significant credit for the Kihabe and Nxuu project.
- Further test work on the iron hydroxide content of the Kihabe Deposit will confirm the host mineral for Germanium.
The stock of explorer and developer Mount Burgess Mining NL (ASX:MTB) was amongst the best performers on the ASX on 28 April 2021. MTB skyrocketed by over 33% and each share quoted A$0.008 with a whopping trading volume of over 78 million. The market capitalisation stood at A$3.96 million.
Mount Burgess is currently developing the project in Botswana- at the Kihabe and Nxuu Zinc/Lead/Silver/Germanium and Vanadium deposits.
The positive sentiment towards the stock seems to have been stirred by the encouraging results from mineralogical test work on samples containing Vanadium from the oxide zone of the Kihabe Deposit.
Mineralogical Test Work Results
Mineralogical test work was conducted by the Department of Earth Sciences, Naples University, and ALS Laboratories on samples containing Vanadium from the oxide zone of the Kihabe Deposit.
- Results depict that the dominant host for Vanadium is the lead-zinc-vanadium oxide mineral Descloizite.
- In Descloizite, Vanadium Pentoxide (V2O5) is 1.785 times the grade of Vanadium, confirming that V2O5 could represent a significant credit for the project.
- To date, the drill holes that have been assayed for Vanadium demonstrate potentially a 200m SW zone along with a 500m NE zone of Vanadium mineralization. This is within the oxide zone of Kihabe’s 2.4km strike length.
- A review of the mineralised drill hole intersections has potential for V2O5 intersections to add to the width of the mineralised domains (as they extend beyond those of Zn/Pb/Ag).
Two things deserve special attention - firstly, these V2O5 zones have the potential to add significantly to the commercial value of the Kihabe Deposit, given the recent increases in prices. Secondly, the previous test work conducted on the totally oxidized Nxuu Deposit confirmed that Vanadium was hosted in Descloizite.
The previous test work also indicated that 80.70% Descloizite can be recovered on site through gravity separation followed by flotation using a hydroximate acid for recovery.
Weighted Average Grades Of Zn/Pb/Ag/V2O5/Ge In Kihabe Zones
Mount Burgess assayed 15 drill holes for Vanadium in the SW zone (Zone 1) and 28 drill holes in the NE zone (Zone 4).
- In calculating the weighted average grades, only the V2O5, Ge grades in the oxide zone were considered with the Zn/Pb/Ag grades.
- The Zn/Pb/Ag grades in the sulphide zone were included in the weighted average grade calculations for those elements.
Germanium Developments at Kihabe
There are six holes drilled into Kihabe and assayed for Germanium. These holes suggest that there can be the possibility to discover further Germanium mineralisation along strike. This can make a substantial commercial contribution as well.
Initial mineralogical test work was conducted by Naples University on the Kihabe Deposit samples containing Germanium-
- The aim of the test work was to determine the host mineral of Germanium.
- The test work concentrated on testing for Germanium minerals associated with Vanadium.
- No Germanium minerals were found to be associated with the Vanadium content.
- Germanium was mostly in the iron hydroxides.
Mount Burgess notified that further test work on the iron hydroxide content of the Kihabe Deposit may confirm the host mineral for Germanium.
