Great Northern Minerals Limited announced that it has been granted exploration licence EL9519 located in the central west of New South Wales, approximately 12kms north of Rylstone and approximately 30 km east of Mudgee. EL9519 is held by GNM's 100% owned subsidiary Greenpower Gold Pty Ltd. The licence area covers a number of Mesozoic alkalic-peralkaline intrusions identical in age and potentially similar to the peralkaline Toongi intrusion. The Toongi intrusion, located in central NSW, hosts significant resources of Zr, Hf, Nb, Ta, Y and REE within a small, rapidly cooled trachyte laccolith.

Toongi is part of regional Late Triassic to Jurassic alkaline magmatic field, but is distinguished from the other igneous bodies by its peralkaline composition and economically significant rare metal content that is homogenously distributed throughout the trachyte body. The primary ore minerals are evenly dispersed throughout the rock and include lueshite/natroniobite and complex Na-Fe-Zr-Nb-Y-REE silicate minerals. The intrusions within EL9519 are considered to have a potential for similar style zirconium-rare earth mineralisation enriched in heavy rare earths.

The proposed exploration program will encompass a systematic review of historical exploration activities to date, followed by initial reconnaissance mapping and sampling over the known intrusions to identify intrusions which host REE mineralisation. Further mapping and sampling will be undertaken to support a first pass drilling program. The target area will be drilled, and should the drilling confirm the presence of potentially economic levels of REE mineralisation, this will be followed up by a more detailed drill program to generate sufficient information to start to model the REE mineralisation as part of early stage resource definition activities.

Radiometrics suggest multiple U-Th-K anomalies within EL9519 associated with the trachytes and phonolites. Ternary radioelement potassium(K)-thorium (Th)-uranium(U) channel data. The image was generated by merging many individual airborne surveys and is a red-green-blue (RGB) composite using a histogram- equalised colour-stretch for each of the three channels.

The red, green and blue channels represent K, Th and U respectively. Mixed compositions are indicated by the proportional blend of the corresponding additive primary colours (e.g. yellow indicates the presence of both K and Th, magenta the presence of K and U while aqua indicates the presence of Th and U). Black indicates low concentrations and white represents high concentrations for all three radioelements.

The distribution of radioelements reflects the geochemistry and mineralogy of the near-surface, which may constitute either bedrock or regolith materials.
