Highlights

  • Mount Burgess Mining NL (ASX:MTB) has been advancing its polymetallic Zn/Pb/Ag/Cu/V/Ge project. 
  • Of the two polymetallic sedimentary exhalative (SEDEX) style Kihabe and Nxuu deposits so far defined, the Company plans to develop the Nxuu Deposit first.
  • Recently, Mount Burgess has been working around Gallium (Ga) and Germanium (Ge), both of which could represent significant credits for the project.
  • Currently, the Company is awaiting assay results from recent drilling conducted at the totally oxidised Nxuu Deposit.

Mount Burgess Mining NL (ASX:MTB) has been moving its polymetallic Zn/Pb/Ag/Cu/V/Ge project forward. The project is situated in Prospecting Licence PL 43/2016, on the Namibian border in Western Ngamiland, Botswana. The 1,000 sq km licence covers a neo-proterozoic belt of SEDEX style mineralisation on the Botswana side of the border. 

Of the two polymetallic sedimentary exhalative (SEDEX) style Kihabe and Nxuu deposits so far defined, the Company plans to develop the Nxuu Deposit first.

Recent milestones

Until now, Mount Burgess has developed 2004 JORC compliant indicated and inferred SEDEX resources of to 25 million tonnes @ 3% Zinc equivalent grade made up of Zinc and Lead, with 3.3 million ozs of silver. While Copper, Vanadium, Gallium and Germanium credits are not yet included in the 2004 JORC compliant resource calculations, at current prices they could represent significant credits. 

The Company has been investigating the potential to exploit additional known metal credits such as Copper, Vanadium, Gallium and Germanium and investigating various metallurgical processes that could be applied to augment the possibility for on-site beneficiation of metal production.  

In this backdrop, let us skim through some of the recent milestones of the Company, as it continues to chart a path forward.  

Memorandum of Understanding (MoU) with Botala Energy Ltd (BTE)

In March 2022, Mount Burgess signed an MoU with Botala Energy. The MoU concerns the possibility for the supply of an energy solution comprising of solar / battery hybrid by BTE, backed by Liquified Natural Gas (LNG), if Mount Burgess adopts this power supply for its Kihabe-Nxuu Project.  

This is a strategic deal as in Botswana, BTE has the potential to provide a power supply and Mount Burgess needs power supply. Discussions have begun for achieving a mutually beneficial solution.

Positive results from test work conducted for Gallium & Germanium

The Kihabe and Nxuu Deposits contain significant intersections of Gallium (Ga) and Germanium (Ge), both of which could represent significant credits for the project. 

Mount Burgess had sent ½ NQ diamond core from the Kihabe deposit to the University of Tasmania, to conduct test work on Ga and Ge mineralisation. Results from laser analysis showed that Ga as well as Ge follow, or are parallel to, the laser signals from Aluminium, Potassium and Iron.  

It is possible that both Ga and Ge are primarily hosted in muscovite (mica). Ga is likely substituting for Al, and Ge is likely substituting for Fe in Al-Fe-K micaceous minerals (muscovite-illite). Neither Ga nor Ge are completely linked with zinc mineralisation. Mica (in the form of flakes) can be recovered by flotation to generate a mica rich concentrate, allowing the recovery of Ga and Ge.

Review of Ga assay results

Mount Burgess recently completed a further review of Ga assay results from the Kihabe Deposit. This was done in light of recent significant price increases in Ga from US$250/kg in 2017 to US$615/kg currently (Kitco Strategic Metals).  

Assaying for Ga has been conducted on seven holes drilled in the October/November 2017 drilling campaign that targeted the Kihabe Deposit upper oxide zone. All holes seemingly contain significant intersections of Ga, alongside intersections of Zn, Pb, Ag, V and Ge. 

The University of Tasmania conducted mineralogical test work on Kihabe Deposit drill core samples to determine the host minerals for both Ga and Ge. Now, further metallurgical testwork is likely to be conducted to ascertain the recoverability of Ga and Ge on site.

Exciting times ahead?

Currently, Mount Burgess is awaiting assay results from recent drilling conducted at the totally oxidised Nxuu Deposit. Close to 1,500m of drilling is required to then enable the Company to quote an Indicated/Measured Resource compliant with the 2012 JORC Code. Exciting times await as Mount Burgess can then proceed to a Pre-feasibility Study. Once having evaluated a commercial power supply, it can proceed to a Definitive Feasibility Study. 

On 6 April 2022, MTB traded up by over 14% at AU$0.008.
