Highlights

• Mount Burgess (ASX:MTB) has released an update on the contribution of vanadium pentoxide, germanium and gallium to the Nxuu deposit.
• The newly added mineralised domains occur above and within the Zn/Pb/Ag mineralised domains.
• The inclusion has added 285% to Zn, Pb and Ag mineralised domains of the deposit.

Australian mineral exploration player Mount Burgess Mining NL (ASX:MTB) has updated on the contribution of vanadium pentoxide (V₂O₅), germanium (Ge) and gallium (Ga) to the Nxuu deposit. The V₂O₅, Ge and Ga mineralised domains occur above and within the Zn/Pb/Ag mineralised domains.

The company has highlighted that the inclusion of V₂O₅, Ge and Ga adds 285% to Zn, Pb, and Ag mineralised domains of the deposit.

MTB recently announced an initial Inferred/Indicated Mineral Resource Estimate (MRE) of the deposit based on assay results from 70 drill holes.

Of the total 70 drill holes used for determining the MRE, 43 drill holes were assayed for vanadium, while 40 drill holes were assayed for germanium and gallium.

MTB methodology for drill holes assaying

MTB methodology included only 43 holes that were assayed for V, and from these 43 holes, 40 were assayed for Ge and Ga. Based on this assaying methodology, the company calculated the proportion of the 43 holes containing zinc, lead and silver and vanadium pentoxide, germanium, and gallium mineralisation, highlighting:

• Mineralised domains of Zn @ 1% +, Pb @ 1% + and Ag @ 10g/t +, totalling 605.5m.
• Mineralised domains of V₂O₅/Ge/Ga totalling 1,198.0m.

Further, 1,118.1m of this 1,198.0m lies above and within the zinc, lead and silver mineralised domains, and the remaining 79.9m lies below the zinc, lead and silver mineralised domains.

Assessing the additional 285% contribution of V₂O₅/Ge/Ga

For assessment, the company used 605.5m of zinc, lead and silver mineralised domains and 1,118.1m of vanadium pentoxide, germanium, and gallium (above and within the zinc, lead and silver mineralised domains), thus cumulating 1,723.6m of zinc, lead and silver, vanadium pentoxide, germanium, and gallium mineralised domains as shown below:

This 1,723.6m increases the primary 605.5 metres of zinc, lead and silver mineralised domains by 285%.

The grades of vanadium pentoxide, germanium, and gallium contained within the 1,118.1m domain, above and within zinc, lead and silver mineralised domains, are as follows:

The inclusion of assay results for vanadium pentoxide, germanium, and gallium together with zinc, lead and silver, in the total metres drilled to the base of mineralisation of the 70 drill holes has led to the following changes:

What’s next?

MTB intends to assess what further contribution could be gained from vanadium pentoxide, germanium, and gallium mineralisation below the 605.5m of zinc, lead and silver mineralised domains after finalising an updated MRE.

The updated MRE would aim the conversion of the current inferred/indicated MRE to a classification of measured mineral resource.
