Machinga

Project Overview

Granted EL, Area: 42.9km2, ELA 157.5km2

The Machinga Project is contained within a large alkaline complex of the Chilwa Alkaline Province that intrudes Proterozoic basement gneisses, granulites and amphibolites. This complex comprises nepheline-syenites of the Mongolwe, Chaone and Chinduzi Ring complexes, the Malosa syenite pluton and minor alkaline granites. The project area is dominated by the Malosa syenite pluton, but also contains discrete and smaller-scale intrusions and pegmatites.

The project area was initially applied for an exploration licence to cover uranium channel radiometric anomalies that were located by a country-wide airborne survey carried out in the 1980s. The Machinga radiometric anomaly is continuous along a strike of approximately 7 km, indicating that potential to discover further eudialyte-hosted REE mineralisation may be significant. The eudialyte is associated with the granitic-syenitic pegmatites, which are the target along the margins of the plutons, as well as in the central zone of Machinga.
