Mount Burgess charges ahead with exciting exploration at Nxuu deposit

Highlights

  • Mount Burgess Mining NL (ASX: MTB) is currently undertaking PQ and HQ diamond core at its polymetallic Nxuu Deposit.
  • Half PQ core together with portions of quarter HQ core can be used to determine operating characteristics of the minerals to underpin the progress towards Pre-feasibility study.
  • Mount Burgess Mining anticipates the drilling to continue after Christmas break.

Multi-commodity explorer, Mount Burgess Mining NL (ASX: MTB) is currently undertaking PQ and HQ diamond core in-fill drilling with two drill rigs at its polymetallic Nxuu Deposit on Prospecting Licence PL43/2016, in Western Ngamiland, Botswana.

Progress in the current drilling program

In the current drilling program, the Company has completed three PQ diamond core holes, with one of them being a twin hole.

Moreover, Mount Burgess has completed 16 diamond core holes, three of which were twin holes in the NW zone of the Nxuu Deposit.

Mineralogical and Metallurgical testwork advances simultaneously

To date, mineral and metallurgical testwork conducted has highlighted significant information.

Mineralogical test work confirmed:

  • Zinc is hosted in the oxide mineral Smithsonite.
  • Vanadium is hosted in the oxide mineral Descloizite, where mas of Vanadium Pentoxide (V205) is 1.785X the mass of Vanadium.

Metallurgical test work conducted has confirmed:

  • Recovery of 93% of Zinc metal on site by acid leaching, followed by solvent extraction and electro-winning (SX/EW)
  • Recovery of 81% Vanadium Pentoxide on site, initially by gravity separation, followed by flotation using hydroximate acid as reagent for recovery to a concentrate.

Further plans

The Company intends to send half HQ diamond core for assaying. Notably, all assay results will be reported to the market as they become available.

Moreover, half PQ core together with portions of quarter HQ core can be used to determine operating characteristics of the minerals involved to take forward the process route to a Pre-feasibility study. It includes:

  • Mineralogy for assessing the economic liberation of mineral assemblage throughout the process
  • Confirming previous test work and refinement of on-site process requirements

 On 29 November 2021, MTB quoted AUD 0.006 on the ASX.
