Soil results from the geochemical programs completed at Killi Resources’ West Tanami Project in WA have established multiple anomalous yttrium values at the Fox prospect.

Three continuous surface yttrium anomalies which extend ~1.5km along strike to the basement sediments have been generated at Fox, with yttrium always found in combination with rare-earth minerals.

“The results indicate the potential for a heavy rare earth system at the Fox prospect,” Killi Resources (ASX:KLI) CEO Kathryn Cutler said.

“These are fantastic first pass yttrium results for the project, indicating we are in the right region, and we plan to develop and drill test this REE target in the coming field season.”

Yttrium a US critical mineral

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 wide 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.

New REE target to test

In addition to this surface anomaly a new rare earth target has been generated from the airborne magnetic and radiometric survey and the compilation of field mapping conducted in the 2022 field season.

Currently there are no rock chips, soils or drillholes at this new target location, and Killi plans to “ground truth” the area in the first quarter of 2023.

Results remain pending for the ~2,500m of aircore drilling, ~890m of diamond drilling, and rock chip samples taken across the West Tanami project in recent months.

The company plans to multi-element assay the downhole pulps from the aircore program, for holes which are adjacent to the rare earth anomalies.
