NOA Lithium Brines Inc. announced that a second diamond drill rig has been mobilized and will commence drilling shortly at the Rio Grande Project located in Salta Province, Argentina. A second rig has been added based on the successful results achieved to date from the ongoing Phase 1 diamond drill program. The third hole started approximately two weeks ago and is well-advanced, and the fourth hole will begin imminently with the addition of this second rig.

Highlights from the completed holes include: Hole 23-001: First hole ever drilled in alluvials surrounding the surface salar at Rio Grande, resulting in the discovery of two thick, high-grade brine aquifers, including: 71 meter ("m") permeable interval with grades averaging 433 milligrams per liter ("mg/l") Li, starting at a depth of 101 m; and 158 m permeable interval with grades up to 925 mg/l Li, and averaging 773 mg/l Li, starting at a depth the depth of 311 m. This aquifer returned some of the grades in the entire region. Results of this hole are encouraging as NOA controls the vast majority of the north and northeast alluvials of the salar at Rio Grande, noted as the high-potential resource growth areas at the Project based on the most recent technical report. Both aquifers returned impressive grades and thickness, including: 158 m permeable intervals with grades up to 556 mg/l Li, and average 440 mg/l, starting at a depth of 17 m; and 149 m permeable interval with gradesup to 552 mg/l Li, and averaged 485 mg/l Li, starting in a depth of 317 m. NOA controls a significant land package over several claims on the surface salar at RioGrand, with a combined on-salar position of over 2,000 hectares (20 square kilometers).
