At Monte Muambe, fluorspar is contained as an accessory mineral in the rare earths ore, and on-going metallurgical studies are also aimed at extracting this fluorspar as a by-product of rare earths. For example, a representative rare earths ore sample from Target 1 sent to SGS Lakefields for metallurgical testing contains 

During the evolution of the Monte Muambe geological system, some of the fluorspar contained in the carbonatite was remobilised  and redeposited in the form of low-tonnage 

 on the edge of the carbonatite intrusion, in particular in an area known as the 

Legacy drilling and trenching data from the Fluorite Zone shows that hydrothermal fluorite veins have a 

thickness ranging from 10 to 20m, with grade of up to over 70% CaF2.

Altona is presently assessing of developing a mine on these fluorspar veins, through metallurgical studies currently being undertaken at Peacocke & Simpson laboratory in Zimbabwe.

The anticipated size and relative simplicity of this project lends itself to fast-tracking, with potential for commercial sales within 12 months of an investment decision.
