NOA Lithium Brines Inc. reported positive lithium results from brine samples from RG23-005, the fifth hole of the Phase 1 diamond drill program at its Rio Grande project. The hole, located at the Juana Azul claim within the salar, completed to a depth of 602 meters ("m"), intersected a high-grade lithium (" Li ") brine aquifer of significant thickness starting from a down-hole depth of only 1 m. Hole RG23-005 was executed with diamond drilling (HQ-size), permitting the extraction of core samples of the salar basin formations and collection of brine samples, where available. Drilling was carried out by Salta-based Hidrotec S.A., under the supervision of NOA's geologists.

Diamond drill hole RG23-005 was completed at a depth of 602 m. At a depth of 1 m, the formations saturated with brine began. The lithology of the well is composed mainly by sand with sulfate intercalations and a lower proportion of crystalline halite, with contents that are variable along the depth of the well. Packer test sampling was carried out and almost the entire depth of the +600 m well returned brine-saturated units (approximately 530 m of the 602 m drilled), except for one horizon ranging 40 m in thickness.

Brine packer samples have been sent for laboratory analyses, including multi-element geochemical analysis for lithium and other relevant elements, and results are expected in the coming weeks. Selected drill core samples were sent to an accredited laboratory for physical property tests, including drainable porosity.
