Korab Resources has discovered rare earth oxide mineralization at its Geolsec project at Rum Jungle in Australia’s Northern Territory.
Geolsec is 5km to the west of the Batchelor project and 11km west of the green Alligator project. Together, the three projects are referred to as the Rum Jungle Project.
Rare earths anomalism has been encountered within the Geolsec formation and within surrounding rocks of Coomalie Dolostone and Whites Formation.
Similar to Arafura Resources’ Nolan’s Bore rare earths deposit in the Northern Territory, the mineralization at Geolsec is associated with phosphatic enrichment. At Geolsec it is also associated with elevated uranium and thorium oxide levels allowing for relatively precise targeting of the deposition zones using ground radiometry and soil geochemistry.
The discovery was a result of a radiometric survey, rock chip sampling and auger soil sampling program which covered prospective stratigraphy. This was followed up by a review of historical costean, test pit and drill assay data in conjunction with recent exploration results.
Reprocessed data for the Geolsec phosphate deposit in the northwest section of the project suggests Geolsec may consist of two types of phosphatic mineralization.
Although the main source of phosphate in both types of mineralization is fluorapatite, while one of the types shows elevated rare earths oxides, the other type appears to have no noticeable rare earths anomalism.
Korab will shortly undertake additional work to assess further the potential of this discovery, including its implications for the development options of the phosphate deposit.
