Usha Resources Ltd. announced that fieldwork at its White Willow Lithium Pegmatite Project (White Willow or the Project), located 170 km west of Thunder Bay, Ontario, has successfully identified additional drill targets at the Bingo lithium-cesium-tantalum (LCT) pegmatite swarms, with the primary dyke swarm expanded to potentially over 1.8 kilometers in strike length. The combination of highly evolved geochemical indicators (Nb/Ta, K/Rb ratios; Ta, Rb, Cs, Li abundances), prospective mineralogy (including white beryl and Nb-Ta oxides) as well as field textures (replacement textures, strong planar fabric) indicate a fluid-rich and highly fractionated dyke swarm that has a strong potential to be spodumene-bearing. The Company now intends to continue beyond the planned six (6) weeks of fieldwork for Phase 3 to further maximize the mapping, sampling and prospecting that can be completed prior to initiating drilling.

Assay highlights to-date include: Lithium oxide (Li2O) values up to 0.5%, with 76 samples containing very anomalous (>300 ppm) concentrations of lithium, including 14 above >1,000 ppm with a sample of the host rock which assayed 1,300 ppm indicating significant lithium-rich fluids are present within the system. Cesium (Cs) values up to 1,730 ppm, with 71 samples containing very anomalous (>100 ppm) concentrations including 10 which are >500 ppm, indicating the samples are being collected from the outer zone of a fertile LCT system, which is where spodumene, if present, will be identified. Tantalum (ta) values up to 120,000 ppm Ta, with 82 samples containing very anomalous (>30 ppm) concentrations including 35 which are >60 ppm, indicative of the presence of a spodumene-bearing pegmatite.

Of note, a high-grade showing of 14.64% Ta2O5 is present at the Maple Leaf Dyke; coarse-grained tantalite is only known to be found at one other locality in Ontario which is the North Aubrey pegmatite at Green Technology Metals (GT1) Seymour Lake Project where GT1 has identified a 9.9 Mt resource at 1.04% Li2O. Rubidium values of up to 3,540 ppm, with 94 samples containing very anomalous (>1,000 ppm) concentrations including 24 >2,000 ppm. Geochemical assessment also indicates the strong potential for spodumene-bearing dykes to be present at the property.

Per Selway et al., potassium/rubidium ratios (K/Rb), are a key tool in identifying these types of dykes; K/Rb ratios of <30 are indicative of rare-earth pegmatites and <20 of spodumene-subtype pegmatites. To-date, 10 pegmatites have been identified with K/Rb ratios <30 with a low of 7.5. Values below 10 are often associated with economic spodumene pegmatites.
