Anson Resources Ltd (ASX:ASN) (FRA:9MY) has decided to accelerate the production of lithium chemicals to Stage-1 of its Paradox Brine Project in Utah, US, following a strategic review and recognition of changing market conditions for lithium.
Engineering and design for the pre-feasibility study (PFS) are well advanced.
Recent work has focused on operational costings and as a result, Anson has also entered several negotiations with equipment, utility and other material suppliers.
The timeframe for an updated Stage 1 lithium preliminary economic assessment (PEA) and brine PFS completion is late first quarter/early second quarter 2021.
This will provide further definition of capital expenditure and operating expenditure expectations, which will be a key catalyst towards advancing project financing discussions.
Stage 1 details
The PFS for the Stage 1 development is a 15,000 tonnes per annum sodium bromide plant and will expand upon Anson’s existing PEA.
Deliverables from the study include the piping and instrumentation diagrams, plant layout and civil work estimates as well as those for utility connections and infrastructure.
As part of the PFS, De Dietrich has been commissioned to produce a process design for the bromine extraction component of the sodium bromide plant.
This includes mass and energy balance, process calculations, equipment lists and specifications, as well as the preliminary plant layout required for the completion of the PFS.
Power supply options
Anson has entered into negotiations with a number of other companies for the supply of equipment, utilities and other supplies.
Most significantly Anson recently commissioned an “Interconnect/System Impact Study” by the local electrical power provider, Rocky Mountain Power, which concluded that the load service required by Anson for Stage 1 of the project can be “accommodated” from two nearby power lines.
Rocky Mountain has provided two power supply options.
Both options only require a metering station to be established.
- Option 1: from the existing 138 Kv line about 1 kilometre from the proposed production site
- Option 2: from the existing 68 Kv power line about 5 km from the proposed production site
The Paradox Brine Project in Utah remains the company’s flagship project and progressing the engineering studies is a significant step forward in its development.
In parallel with the development of this project, Anson continues with the exploration of its base metal projects in WA, with a strong focus on ‘The Bull’ Project, 20 kilometres along strike of Chalice Gold Mines (ASX:CHN) (OTCMKTS:CGMLF) (FRA:C8U) high-grade nickel-copper-PGE Julimar discovery.
Anson is well funded to execute its near-term work programs on both the Paradox Brine and The Bull projects respectively.
