Killi Resources Limited Announces Yttrium-REE Anomaly Identified At West Tanami Project
anomalous for Y-Dy-Nd (3x background values) and the two outer anomalies are anomalous for Y-Dy. These are significant first pass results, where the Company plans to multi-element assay the downhole pulps from the aircore program, for holes which are adjacent the rare earth anomalies. The composite drill pulps from the aircore drilling have been analysed by pXRF, for a purely qualitative purpose and indicate the presence of hydrothermal alteration. Yttrium is classified as a rare-earth element and is often found in combination with `lanthanide' elements in rare-earth mineral systems. Elevated yttrium values are indicative of a potential rare-earth bearing
mineral system, and in this instance, it will be used as a pathfinder element. Yttrium is a transitional metal with a which variety of uses, most importantly in the use of LEDs and phosphors, electrodes, lasers, superconductors and was added to the United States list of Critical Minerals in 2022. Rare Earth mineralisation of the Tanami Region Regionally there are multiple occurrences of REE's in the Tanami district, with surface mineralisation in the form of rock chips at the Killi Killi East Project, 12.45% TREO's, and the Boulder Ridge Project, 12% TREO's to the east of Killi Resources tenure. The mineralisation style of both these projects is believed to e hydrothermal, unconformity related. Where REE-rich hydrothermal fluid moves through the rocks and deposits preferentially within a host lithology, which in this instance is the Pargee Sandstone. The Browns Range REE Mine, owned by Northern Minerals Limited, is located 55km north of the Fox prospect. The deposit is currently not in operation, however, has a current resource of 9.28Mt @ 0.67% TREO's. The mineralisation style of this deposit is hydrothermal, with the individual localised REE deposits located around the margins of the Browns Range Dome. In addition to the geochemical results, the airborne magnetic and radiometric data has been interpreted, with an additional rare earth target generated. The radiometric data suggests a potential REE target may be present, with the magnetics highlighting a zone of demagnetisation, potentially indicating hydrothermal alteration. This was compared with the recently compiled surface mapping, which had recorded the prospective Pargee Sandstone at this location. Within the region REE mineralisation has been associated with the sandstone as it provides a suitable lithology for the
deposition of mineralised hydrothermal fluids. Currently there are no rock chips, soils or drillholes at this new target location. The Company plans to ground truth the area in the first quarter of 2023.
