Lake Resources JORC Update Increases Measured and Indicated Resource by 250% for its Flagship Kachi Project

• Deeper drilling to 600 m bgs has led to significantly larger resource estimates.
• Measured and Indicated Resources have increased from 2.9 to 7.3 Mt of LCE defined to a depth of 600 meters over 143.8 square kilometres^[1].
• The updated total resource estimate exceeds 10.6 Mt of LCE^[2].
• Previous testing confirmed highly favourable subsurface conditions for both lithium extraction and injection in the central resource area where the M&I resources are located^[3].
• Surrounding the Measured and Indicated Resources are Inferred Resources of 3.3 Mt LCE defined over 130.9 km².
• K24D41 in the southern sector intersected some of the highest lithium concentrations drilled to-date at the project, returning grades of 180-348 mg/L lithium over 445 m (166 – 610 m) with an average of 267 mg/L.
• Deeper drilling at K23D40 in the northern sector intersected coarse-grained alluvial fan materials and averaged 228 mg/L over 322 meters with a maximum of 254 mg/L. This hole is 3.5 km northwest of K22R39.

SYDNEY, Nov. 23, 2023 /PRNewswire/ — Clean lithium developer Lake Resources NL (ASX: LKE; OTC: LLKKF) (“LAKE” or “the Company”) is pleased to provide an updated resource estimate for the Kachi lithium brine Project (“Kachi” or the “Project”) in Catamarca Province, Argentina.

The updated resource estimate is based on continued hydrogeological characterization since the last update in June 2023^[4] and refined interpretations of the hydrostratigraphy, hydrogeology and hydrogeochemistry.

This resource update defines the Mineral Resources to be used in the hydrogeologic model for the forthcoming maiden reserve estimate and will be the basis for the Project Phase 1 Definitive Feasibility Study (DFS) expected in December 2023.
