Lithium Power International Limited provided details of the maiden Ore Reserve and Mineral Resource update for its Maricunga lithium brine project in northern Chile. The Mineral Resource estimate consists of 100% Indicated and Measured Resources, with the previous 20% Inferred Resources converted to Indicated Resources following the drilling of two additional sonic holes to 200 m in 2H18 for a revised Resource of 2.07 Mt of lithium Resources. The estimated Mineral Resources used in the Definitive Feasibility Study has been prepared by competent persons and reported in accordance with requirements of the 2012 JORC code. A hydrogeological model was developed to define a maiden brine Reserve for the project, taking into account brine recovery from the aquifers in the salar. An overall mining Reserve of 742,000 tonnes of LCE has been defined, for brine extracted from the aquifer and pumped to the ponds, of which 203,000 is classified as Proved and 539,000 as Probable (Table 3). Proved Resources represent those in the old mining code Cocina property and the first 7 years of production from the Litio properties in the salar. The remaining Reserves are classified as Probable. When the lithium pond and process recovery efficiency of 58% is applied, the total recovered LCE equates to 430,000 tonnes, of which 27% derives from Proved Ore and 73% is derived from Probable Ore in brine fed to the ponds. This 430,000 tonnes of defined Reserve for the project exceeds the 20 years of production at 20 Ktpa of lithium carbonate, based on the Resource and Reserve defined to 200 m depth. The company believes there is also considerable scope to add additional Resources, and probably Reserves, below the current Resource drilling depth of 200 m.
