SnapshotMSB received its environmental approval (RCA) for the Maricunga Project on February 4, 2020. The Environmental Impact Assessment (EIA) was submitted to the Chilean Authority, Servicio de Evaluacion Ambiental (SEA), in September 2018.

The EIA approval represents the final major regulatory milestone in advancing the Project, which is now ready to move towards construction subject to completion of Project Financing.

An updated Definitive Feasibility Study (DFS) is due for release in mid-January 2022.

Lithium Power International Limited (LPI) will be removed from the Official 15 March 2024 in accordance with Listing Rule 17.11, following implementation of the scheme of arrangement between LPI and its shareholders in connection with the acquisition of all the issued capital in LPI by Corporación Nacional Del Cobre de Chile (Codelco), through its wholly owned subsidiary Salar de Maricunga SPA.

Deposit type

  • Evaporite

Summary:

Based on the drilling campaigns carried out in the Salar between 2011 and 2021, eight major geological units were identified and correlated from the logging of drill cuttings and undisturbed core to a general depth of up to 400 m. Only borehole S-29 on the western edge of the Salar encountered bedrock at 219 m depth. Salar de Maricunga is a mixed style salar. An upper halite unit occurs (up to 34 m in thickness) in the central northern part of the Salar and hosts the upper brine aquifer. The halite unit is underlain by low permeability lacustrine sediments. The Salar is surrounded by relative coarse grained alluvial and fluvial sediments. These fans demark the perimeter of the actual salar and at depth grade towards the centre of the Salar where they form the distal facies with an increase in sand and silt. At depth two unconsolidated volcanoclastic units have been identified that appear quite similar. These two volcanoclastic units are separated by a relatively thin and continuous sand unit which may be reworked material of the lower volcanoclastic unit. A volcanic breccia was identified on the northern and western parts of the OCC that locally interfingers with the lower volcanoclastic unit. A lower brine aquifer is hosted in the lower alluvial, volcanoclastic, and volcanic breccia units (below the lacustrine sediments).

Mineralization
The brines from Maricunga are solutions nearly saturated in sodium chloride with an average concentration of total dissolved solids (TDS) of 311 g/L. The average density is 1.20 g/cm3. Other components present in the Maricunga brine are: K, Li, Mg, Ca, SO4, HCO3 and B. Elevated values of strontium (mean of 359 mg/L) also have been detected.
