Paradox Lithium Project
The Paradox Lithium Project is Anson’s core asset. It is an advanced development project, covering an area of 167km2 in the Paradox Basin in southern Utah, in the USA.
Anson is focused on developing the Paradox Project into a significant lithium producing operation, to provide high-quality lithium carbonate for the rapidly growing EV battery market:
- Commercially proven Direct Lithium Extraction (DLE) technology: Anson’s lithium extraction process technology has been in commercial use since 2018 and currency produces 32,000 tpa of lithium carbonate at 7 projects.
- Low carbon and waste: Hydro and solar energy power the project and brine is reinjected underground post lithium extraction.
- High subsidy for consumers and project loans: US lithium producers can access low interest loans from the Department of Energy and consumers purchasing an EV with US sourced lithium batteries receive a $3,750 subsidy.
- DFS confirms strong project economics: Low-cost, long-life project with material upside to include expand lithium production and bromine production.
- Substantial JORC Resource: 1Mt of Lithium Carbonate Equivalent (LCE) and 5.275Mt of Bromine1– Major Resource expansion program underway.
The Paradox Project is held by Anson’s US subsidiary A1 Lithium. Click here to go to the A1 Lithium website.
Definitive Feasibility Study
The September 2022 DFS for Phase 1 of the Paradox Lithium Project confirmed the Project’s advanced potential to become a major supplier of high purity, battery grade Lithium Carbonate into the US Electrical Vehicle market.
The DFS proposes that the Project will produce 13,074 tonnes per annum of high purity Lithium Carbonate over an initial 10-year project life, and then produce lower commercial levels up to a production life of 23 years (assuming no further Mineral Resource expansion and that no other extraction wells will come on-line).
Phase 2 development of the Paradox Project is proposed to comprise further substantial increases in lithium production capacity plus bromine production.
Key financial highlights of Phase 1 DFS are presented in the Table below.

| Base Case | $1,306m | 47% | $922m | 37% |

Major Mineral Resource
The Paradox Project hosts a major JORC Mineral Resource of;
1,504,237 tonnes of lithium carbonate equivalent (LCE) and 7,608,700 tonnes of bromine, including,
– Indicated Resource of 366,737 tonnes of LCE and 1,910,000 tonnes of bromine; and
– Inferred Resource of 1,137,500 tonnes of LCE and 5,698,700 tonnes of bromine

Table: Paradox Lithium Project Total JORC Mineral Resource estimation1.
The Mineral Resource incorporates drilling and sampling by Anson at the Cane Creek 32-1 well and the Long Canyon Unit 2 within the Project area. The Resource also includes significant amounts of other minerals including Bromine (Br2), Boron (Boric Acid, H3BO3) and Iodine (I2)
Resource Expansion Program
Anson is seeking to further expand the Paradox Project’s Mineral Resources, by targeted drilling and sampling in the western region of the Project. The results of the ‘Western Expansion’ strategy are expected to deliver an upgrade to the existing Mineral Resource, which was confirmed from drilling and sampling in the eastern area of the Project. It also plans to define a Mineral Resource at the nearby Green River Lithium Project, which would be added to the Company’s global Mineral Resource in the Paradox Basin.
