Gallium Assays

In light of recent significant price increases in Gallium (Ga) from US$250/kg in 2017 to US$615/kg currently (Kitco Strategic Metals), the Company has completed a further review of Ga assay results from the Kihabe

useD posit. (Please refer to announcement of 20 January 2022 for Ga assay results from the Nxuu Deposit).

Kihabe Deposit - Gallium Content

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

personalAll assay results from Zn, Pb, Ag, V and Ge have previously been reported. The Ga results now being reported because of the recent significant price increase of Ga, show that they could represent a significant credit for the Kihabe Deposit (Refer to Table 1 and Figures 2 to 9). As can be seen, in drill hole KDD201, continuous Ga mineralisation occurs over a 60 degree inclined down hole intersection of 91m - refer Figure 6. The Kihabe Deposit is 7km west of the Nxuu Deposit.

Mineralogical and Metallurgical Test work on Gallium

The University of Tasmania is currently conducting mineralogical test work on Kihabe Deposit drill core samples to determine the host minerals for both Ga and Ge. Once determined, further metallurgical test- work will be conducted to ascertain the recoverability of Ga and Ge on site.

Gallium Uses

Ga has many modern applications, such as:

For• Electronics, semiconductors, transistors, mobile phones

• Pressure sensors for touch switches

• Converting electricity into light via Light Emitting Diodes (LEDs)

• Blue Ray Technology

Ga is also used as an alloy with most metals, particularly low temperature melting alloys, as it has a high boiling point.
