PROJECT OVERVIEW

In 2023, EnergyX made a significant leap by acquiring a ~100,000-acre lithium resource in Chile, where we plan to develop one of the world’s first commercial Direct Lithium Extraction (DLE) facilities, along with a refinery near the port. This project, known as Project Black Giant™, marks the company’s first lithium acquisition. Here’s a closer look at the exciting details of this groundbreaking venture:

100,000+ acres of high-quality lithium mining concessions.
Total potential ranges from 4.5 to 9.8 million metric tons of lithium
Well samples show lithium concentrations topping 1,150 mg/L
With our technology, we estimate Project Black Giant will be able to produce 52,500 tpa LCE of lithium per year.

Resource Location & Size	100,000+ Acres in Antofagasta Region
Initial Annual Production	7,500 tpa LCE (Phase I), 52,500 tpa LCE (Phase I & II)
Production	99.9% Battery Grade Li₂CO₃

PROJECT PROGRESS

At Project Black Giant™, EnergyX is making incredible strides. The pilot plant in Antofagasta is producing battery-grade lithium, a critical milestone that demonstrates our technology’s commercial viability. We’ve fully built out a 54,000-square-foot facility—including laboratories, offices, a cantina, and pilot/demo facilities—to process Black Giant brine.

The exploration team has grown and continues around the clock operations. They have successfully completed the 14-hole Phase 1 Drilling Program, and are now underway with Phase 2 Drilling.

PROJECT FEASABILITY STUDY

In partnership with:

Study approach

EnergyX has successfully finalized the Pre-Feasibility Study (PFS) for its Chilean lithium resource, Project Black Giant™, in partnership with Montgomery & Associates, Geobiota, and Worley. The study confirms the economic viability of the project, marking a significant step toward commercial-scale lithium production, while also highlighting EnergyX’s industry-leading low CapEx and OpEx. Additionally, the full resource report for the Project Black Giant resource underscores the project’s long-term potential.

The PFS study validates the feasibility of the project, demonstrating that large-scale lithium extraction and production are both economically and technically viable. Collaboration with Worley enhances the overall project development strategy, ensuring efficiency and sustainability.

As EnergyX advances toward full-scale commercialization, these results further solidify the company’s strategic leadership in the lithium industry. By demonstrating exceptional extraction efficiency and economic viability, EnergyX is strengthening its competitive edge while ensuring long-term sustainability, resource security, and the scalability necessary to meet the surging global demand for lithium.

Dle Plant Process Overview

Dle plant facility

The DLE processing plant includes Brine Pre-Treatment, Adsorption, RO, Ca-Mg Removal, Ca-Mg and Boron IX, and Brine Evaporation units. The facility also consists of reagent storage and preparation areas, utility systems (power, water, and air distribution), a laboratory, and a centralized control station.

Dle Plant Process Overview

FILTRATION (FX)

The raw brine from the storage pond contains suspended solids and other contaminants that could affect adsorption column operations.

Therefore, the brine is pretreated using candle filters. The treated brine then gravitates to the nearby adsorption feed pond. The brine goes through 5-micron strainers before entering adsorption columns.

The eluate and the spent brine coming from adsorption is also filtered before going to the respective storage ponds.

The filtration system is designed for a capacity of 2,712 m³/hr, providing a 30% margin above the required brine flow rate.

Dle Plant Process Overview

ADSORPTION (AX)

The adsorption system consists of 18 columns arranged in six rows, with three columns per row. Each column measures 21 ft in diameter and 9 ft in height. Each column is designed for a flow rate of 520 m³/hr.

The eluate (product brine) from each row of columns gravitates to the eluate pond for further processing. The overall system features a high degree of process automation, minimizing labor requirements.

Each row of three columns is capable of producing 7,500 up to 15,000 tpa LCE with adsorption improvements, depending on feed grade and productivity.

REVERSE OSMOSIS (RO)

The RO system has a design capacity of 2,880 m³/hr, with each RO unit processing 480 m³/hr. The system includes six operating units, housed within a total of thirty-six 40-ft containers. Six of the 40-ft containers operate as one unit.

Eluate from the AX process is concentrated through a series of RO membrane stages to achieve a final brine total dissolved solids (TDS) of 8%. The feed eluate has a TDS of 0.58%. The RO skids are provided as a full turnkey solution, designed for plug-and-play operation.

Dle Plant Process Overview

FILTRATION

The precipitated calcium and magnesium cake from the reaction tanks is pumped to the filtration stage.
The filtration stage consists of two membrane filters – one in operation and one on standby.

Each filter press is equipped with a total of 155 polypropylene (PP) filter plates.
The mass flow rate of each filter press is 203 t/h, with a solid concentration of 0.6%.

The filtration area per chamber is 3.66 m², giving a total filtration area of 564 m² per filter press. The target cake thickness before squeezing is 35 mm The total wet cake volume per filter press is 8.9 m³.

BORON, CALCIUM, MANGESIUM EXCHANGE (IX)

The polishing step consists of a two-stage ion exchange (IX) system. The first stage removes residual calcium and magnesium from the brine solution. The second stage performs boron ion exchange for further purification.

Each IX stage consists of three columns operating in a lead– lag and regeneration configuration. The columns are constructed from fiberglass reinforced plastic (FRP).

The IX stages are provided as a full turnkey solution, designed for plug-and-play operation. Each stage is supplied with online regeneration support system.
