Nov 16, 2023 (Therese Pettigrew) - An LCT swarm, “Bingo”, has been identified that is over ~2 km in length that includes 2 large pegmatites that outcrop 600 and 450 metres in length, respectively, and are up to 75 metres in width. If connected, they would form a single large dyke over ~1.2 km in length. Bingo is highly evolved with low K/Rb and Nb/Ta ratios and mineralogical (spessartine garnets, blue-green apatite, lithium amphiboles) indicators for a potential spodumene-bearing system. Usage of a LIBS (laser-induced breakdown spectroscopy) analyzer on samples indicated lithium values within the Bingo dike up to ~1.3% Li2O and ~0.65% Li2O within the host rock. A LIBS analyzer is a portable device that provides semi-quantitative assessments of geochemical concentrations in real-time. These readings should not be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. LIBS readings are not representative of the whole core and represent purely a concentration measured at a single point. (Usha Resources press release Aug 3, 2023).
