Latest News Release -


  • The Company has completed 5 weeks of fieldwork, expanding the lithium-cesium-tantalum ("LCT") pegmatite trend on the property to a potential strike length of >25 km open at both ends.
  • A total of 837 samples have now been collected at the Project, highlighting multiple drill targets. Assays for 219 samples are pending receipt and analysis. Highlight results include up to 0.5% Li2O, 1,730 ppm cesium, 120,000 ppm tantalum and 3,540 ppm rubidium.
  • Geochemical results indicate the strong potential for spodumene-bearing dykes to be present at the property. 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[i]. 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.
  • The Company intends on drilling each of the 10 target pegmatites as part of its maiden drill program.

VANCOUVER, BC, Sept. 14, 2023 /PRNewswire/ -- Usha Resources Ltd. ("USHA" or the "Company")(TSXV: USHA) (OTCQB: USHAF) (FSE: JO0), a North American mineral acquisition and exploration company, is pleased to provide this update on its on-going field program at the White Willow Lithium Pegmatite Project ("White Willow" or the "Project") located 170 km west of Thunder Bay, Ontario.

The Company has completed 5 weeks of fieldwork this season, with data compilation complete for 618 samples. Assay highlights 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.

Each of these pegmatites are planned to be drilled as part of the maiden drill program scheduled to commence in Q1 of 2024.

The Maple Leaf and Bingo Pegmatite Dike Swarms contain highly evolved LCT-pegmatites with excellent geochemical (low K/Rb and Nb/Ta ratios) and mineralogical (spessartine garnets, blue-green apatite, lithium amphiboles) indicators to be potentially spodumene bearing.

The Company will return to Site in October to complete additional prospecting and mapping after which it will proceed with geophysical surveys to outline structures prior to commencing the drill program.

"We are thrilled with the findings from the initial programs at White Willow," said Deepak Varshney, CEO of Usha Resources. "As seen at Patriot Battery Metals' Corvette Project, which has over 20 kilometres of trend, lithium pegmatite swarms occur in clusters, each of which has the potential to become a deposit. We now have 10 primary target areas across our 25 kilometre plus trend that include two highly evolved LCT pegmatite swarms at Bingo and Maple Leaf. With significant ground remaining between Bingo and Maple Leaf for further exploration and follow-up, we intend on maximizing the remaining time in the field season before commencing preparations for maiden winter drill program. The findings thus far strongly validate our belief that Willow is a flagship asset where Ontario's next major lithium discovery will occur."

The tantalite, spessartine garnet, and holmquistite indicate that the system is highly evolved and potentially spodumene-bearing. (PRNewsfoto/Usha Resources Ltd.)

Quality Assurance/Quality Control

All collected rock samples were put in sturdy plastic bags, tagged, and sealed at site. Sample bags were then put in rice bags and kept securely before being sent by road transport or delivered by the crew supervisor to either AGAT Laboratories Ltd. or Activation Laboratories in Thunder Bay, Ontario. All samples are analyzed with Four-Acid Digestion/Combined ICP-AES/MS package (49 elements). The QA/QC protocol included the insertion and monitoring of appropriate reference materials, in this case high concentration and low concentration certified OREAS and CDN lithium standards to validate the accuracy and precision of the assay results.
