Mount Burgess Mining NL (ASX:MTB) Successfully Distributes Drill Core for Test Works


  • Mount Burgess Mining NL (ASX:MTB) is currently developing the Kihabe and Nxuu Zinc/Lead/Silver/Germanium and Vanadium deposits in Botswana.
  • The Company has successfully transported ~1,310 kg of drill core from Maun to Johannesburg and distributed it for test works.
  • Energy and Densification Systems, STEINERT (Australia) Pty Ltd and Naples University will conduct metallurgical and mineralogical test works, using the drill core.
  • Mount Burgess’ 2020 Annual General Meeting of the shareholders will be held via virtual technology on 30 November 2020.

In October 2020, Mount Burgess Mining NL (ASX:MTB) assembled a team within Botswana to access site and collect drill core from the lucrative Nxuu and Kihabe deposits. Ever since, market participants have been eagerly awaiting a progress report.

On 9 November 2020, the Company notified that a team within Botswana has been successful in not only accessing the Kihabe-Nxuu project site, but also collecting around 1,310 kg of drill core for further test works.

Mount Burgess shares traded at $0.007 on 9 November 2020.


Successful Drill Core Collection & Distribution from Maun

Approximately 1,310 kg of drill core has finally been transported from Maun in Western Ngamiland, Botswana, to Johannesburg in South Africa. The drill core has also been distributed to various parties, who will now conduct metallurgical and mineralogical test works on them.

Whilst compliant with the local COVID-19 restrictions, a team within Botswana accessed the Kihabe and Nxuu deposits for the collection of drill core.

In October 2020, ~ 1,560 kg of drill core was transported 370 km from site, close to the Namibian border, to Maun in Western Ngamiland, Botswana. Since then, the Company had been planning for the drill core to be transported from Maun to Johannesburg, South Africa.

Test Works & Their Significance

Three major test works are anticipated to support Mount Burgess’ understanding of the Kihabe-Nxuu project’s potential. The metallurgical test work will shed light on the power requirements to get Nxuu Deposit into production. Mineralogical test work is likely to determine Nxuu Deposit’s host mineral for Germanium and Kihabe Deposit’s host minerals for both Vanadium and Germanium.

Energy and Densification Systems (EDS)

  • EDS Bulk Vertical Milling test work is likely to commence on 9 November 2020
  • It should take around two weeks to complete.

EDS South Africa expects that their Vertical Milling process will work excellently on the Nxuu Deposit ore owing to it being soft and fully oxidised. The EDS Vertical Mill merely requires 25% of the amount of power needed to operate a conventional Ball/SAG/Rod mill.

Mount Burgess opines that there is a possibility of further significant saving in power requirements and power costs, if the bulk test work is successful.

STEINERT (Australia) Pty Ltd (STEINERT)

  • Bulk Sensor Sorter X-ray test work is yet to be conducted
  • Intertek South Africa will courier the drill core via DHL to Intertek, Maddington, Western Australia. Once at Intertek Maddington, STEINERT will collect the core and begin the test work.

Initial Sensor Sorter X-ray test work on Nxuu Deposit ore gave very encouraging results, owing to the deposit’s oxidised nature that enables the X-ray beam to penetrate far more deeply than normal.

By applying the Sensor Sorter X-ray process after crushing, 45% of all crushed product over 4mm was rejected as insignificantly mineralised. Only 55% of crushed ore will then be subject to milling and downstream treatment.

Bulk test work now needs to be conducted to affirm these results and ascertain the recoveries of the -4mm product. As milling consumes the maximum power in mining operations, a significant saving in power requirements and power costs is likely.

Naples University, Italy

  • Mineralogical test work is yet to be conducted.
  • Intertek South Africa will courier the drill core through DHL to the University.
  • The aim is to determine the host minerals for Vanadium and Germanium.

The mineralogical test work will determine the host minerals for Vanadium and Germanium, using the Kihabe Deposit drill core.

In early 2020, drill core from the Nxuu Deposit was sent to the University for mineralogical test work to confirm the host mineral of Germanium. Owing to COVID-19 restrictions, the test work was delayed. However, test work began in the September 2020 quarter, conducting basic X-Ray Defraction (XRD) mineralogy in thin section, together with Scanning Electron Microscopy (SEM).
