  • Results from laser analysis has indicated that both Ga and Ge follow, or are parallel to, the laser signals from Aluminium (Al), Potassium (K) and Iron (Fe).
  • Ga and Ge have been declared as strategic metals by the US Government and are included in the US critical minerals list.
  • Diamond core from the KIHABE polymetallic deposit was recently sent to the University of Tasmania for test work on Gallium and Germanium mineralisation.

Mount Burgess Mining NL (ASX:MTB) shares soared 20% on 3 March 2022 from the previous close as the Company announced impressive results from test work conducted on Kihabe Deposit drill core samples for Gallium (Ga) and Germanium (Ge).  

Against the backdrop of the buoyant Germanium and Gallium market, results from laser analysis showed that both Ga and Ge follow, or are parallel to, the laser signals from Aluminium (Al), Potassium (K) and Iron (Fe).

The Company recently sent ½ NQ diamond core from the KIHABE polymetallic deposit to the University of Tasmania to conduct test work on Gallium and Germanium mineralisation. Notably, both Ga and Ge have been declared as strategic metals by the US Government.

Overview of the results

The Kihabe and Nxuu polymetallic Zn/Pb/Ag/V/Ga/Ge deposits contain significant intersections of Ga and Ge, both of which could represent significant credits for the project.

With this identification, there is potential that both Ga and Ge are primarily hosted in muscovite (mica), with Ga likely substituting for Al and Ge is likely substituting for Fe in Al-Fe-K micaceous minerals (muscovite-illite). Neither Ga nor Ge are directly associated with zinc mineralisation.

Mica in the form of flakes, can be recovered by flotation to produce a mica rich concentrate. It therefore could enable the recovery of both Ga and Ge. The Company indicated that additional metallurgical test work would be required to confirm recoverability.

Gallium tops on the US critical minerals list

The results are significant given substantial price increase in Gallium. In terms of supply dependency, Gallium is currently ranked as #1 on the US critical minerals lists highlighting the emerging issues in crucial supply chains and potential disruptions to gallium availability. Critical minerals serve an essential function in the manufacturing of a product, the absence of which could negatively impact the economy and national security.

Indonesia’s recent ban on all coal exports to China, the major Gallium supplier for the US has affected gallium availability for the country. Notably, the US imports 99% of its Gallium from China, which extracts a lot of Gallium from the Indonesian coal exports. Amidst the recent ban on coal exports to China, the price of Gallium has soared suddenly, and the mineral has gone to #1 on the US Mineral Supply dependency list.

GaN (Gallium Nitride) power transistors, that operate at higher voltages and higher power density are anticipated to increase in the future.

Wide range of Germanium Applications

Germanium, which ranks 24 on the US most critical elements lists boasts a range of applications. It is used for Fibre optic systems as its addition to glass core of fibre optic cables increases refractive index, thereby minimising signal loss over long distances.

Germanium is also utilised in producing of infra-red imaging devices, such as windows, camera lenses and optical lenses which can be used in night vision systems and defence applications

Ge uses are expected to increase in the future for generating ultra-fast transistors used in quantum computers and ultra-fast communication in fibre optics. Given photovoltaic solar panels using Germanium are most efficient, Germanium is also used for construction of photovoltaic solar panels for large scale renewable energy generation.
