The area within and just outside the 3Q Project catchment is characterized by volcanic cones reaching heights of 6,000 masl or greater. Successive tectonic episodes and reactivation of hydrogeomorphological dynamics in an extremely arid environment have formed low level drainage networks. This has resulted in conformation of inter-mountain basin areas and positive relief in the area. Salar in-fill units were differentiated in 3Q Salar and are the target of the current exploration. These salar in-fill units, or hydrostratigraphic units, from deepest to shallowest are:

- Fanglomerate - overlies the hydrogeologic basement and is composed of fanglomerates, medium-coarse sandstones and breccias;
- Lower Sediments - composed of sandstones and siltstones with minor gypsum laminae;
- Massive Halite - composed of fine to coarse-grained halite;
- Porous Halite - composed of medium to coarse-grained halite, with granular intervals of loose crystals;
- Upper Sediments - composed of reddish sandstones, silty sandstones, and plastic shales, mixed with halite crystals; and
- Hyper-Porous Halite - composed of medium to coarse-grained halite with high inter-crystalline porosity.

Overall, the information at the 3Q Project indicates that the lithium and potassium grades and the levels of impurities compare favourably against other brine deposits.

The 3Q Salar has aspects of both evaporite-dominant and clastic-dominant salar types. Withi ........

A primary constraint for the production wells was that drawdown should remain above the screened section of the wells. If excessive drawdown was predicted, then additional wells would be added to the simulation at appropriate spacing. In terms of general well locations, the grade constraints required that the wellfield is located in the higher-grade northern area of the Resource Zone. This northern area also addressed the constraint for Reserves categorization which specified that recovery should focus on Measured and Indicated Resources.

Production wellfield scenarios were adjusted iteratively in the model to identify configurations that could effectively meet all constraints. The final selected scenario included a total of 15 production wells. The wells were grouped into the following three series:
• A-series wells – Selected to meet grade constraints. This series consisted of 9 wells (3 existing and 6 new) that targeted the highest-grade lithium Resource (>1,000 mg/L).
• B-series wells – Selected to meet early pond-filling requirements, and to blend with A-series wells to meet the lithium grade target of 940 mg/L. This series consisted of four wells, all existing, within the mid-grade lithium Resource (>650 mg/L) in the northern salar.
• C-series wells – Selected to enhance LCE recovery after the 20 years of production. This series consisted of 2 wells, 1 existing and 1 new, located east of Laguna 3Q. They target the highest-grade lithium Resour ........
