The Burke Graphite Project is important for the company because it represents an opportunity to participate in the anticipated growth in demand for graphite and graphite-related products.
The Burke Graphite Deposit is in the Burke Tenement (EPM 25443) and currently has a 6.3Mt JORC Inferred Mineral Resource Grade of 16% Total Graphitic Carbon (TGC) which includes a higher-grade component of 2.3Mt @ 20.6% TGC.
The objective of the RC infill drilling program at the Burke Tenement is to upgrade the category of the Burke Deposit from a JORC Inferred Mineral Resource to a higher standard JORC Indicated Mineral Resource. The drilling program consists of a combination of reverse circulation (RC), diamond core and geotechnical holes.
DDH1 Drilling has completed the RC component of the RC Infill drilling program at the Burke Tenement, with 2,306 meters drilled across 23 holes. Samples have been submitted for assaying and the results are expected sometime around late January-February 2023.

If the weather conditions are favorable, DDH1 will initiate the next component of the drilling program at the Burke Tenement around early to mid January 2023. This component is expected to comprise of diamond core and geotechnical holes totaling approximately 600 meters across more or less 6 holes to maximum depths of around 120 meters.
The diamond core will provide representative graphite samples of the Burke Deposit for an extensive metallurgical, Purified Spherical Graphite (PSG), and anode test-work and development program.

Burke Graphite as feedstock material
The upgrade in the resource classification of the Burke Deposit coupled with the metallurgical and PSG optimization test-work will support the planned Engineering Study which will assess the viability of establishing a PSG Anode manufacturing facility. This facility will use Burke Graphite as feedstock material.
Once the RC Infill drilling program at the Burke Tenement is completed in January 2023, DDH1 will mobilize to the Corella Tenement (EPM 25696). The latter is located around 150 km south of the Burke Tenement and the drilling program at the same will test the extent of graphite mineralization in the area.
The mineralization at the Corella tenement was previously identified through sampling and Electro Magnetic (EM) surveys which were conducted with the goal of delineating a maiden JORC Inferred Mineral Resource. Approximately 2,000 meters of RC Infill drilling and around 200 meters of diamond drilling are planned at the Corella tenement. These are expected to provide assays and samples for supporting resource development and metallurgical test-work.
Concurrently, Lithium Energy Limited is also developing its flagship Solaroz Lithium Brine Project in Argentina. This project includes 12,000 hectares of highly prospective lithium mineral concessions located strategically within the Salar de Olaroz Basin in South America’s “Lithium Triangle” in north-west Argentina.
The Solaroz Lithium Project is directly adjacent to or principally surrounded by mineral concessions being developed into production by Allkem Limited and Lithium Americas Corporation.
