Highlights

Green River received a Small Mining Operation approval for its planned lithium carbonate plant.
The planned plant capacity is 10,000 tonnes per year.
The Definitive Feasibility Study is scheduled for the first quarter of 2027.
Utah incentives are contingent on future operating performance.
September quarter cash was A$3,461,181.

Anson Resources Limited (ASX:ASN) is a critical minerals developer focused on lithium brine projects in Utah, including Green River, according to its official website. Its September 2026 quarterly report stated that Small Mining Operation approval for a proposed 10,000-tonne-per-year lithium carbonate plant completed the project's major government permitting requirements. That regulatory milestone advances development readiness, although a feasibility study, commercial arrangements and additional project funding are still outstanding.

What the Utah approvals cover

Anson Resources (ASX:ASN) said the Small Mining Operation authorisation followed an earlier Underground Injection Control approval. The company is undertaking a Definitive Feasibility Study begun in July 2026, with completion targeted for the first calendar quarter of 2027. Having major government permits does not constitute a final investment decision or proof that construction financing has been secured. The company also expanded its land position by approximately 20.78 square kilometres through tenure arrangements, but noted that a school trust lease was not yet signed. Its revised project layout remains subject to ongoing engineering work.

Resource base and engineering assumptions

The September report retained a Mineral Resource of 773,000 tonnes of lithium carbonate equivalent, comprising 183,000 tonnes Indicated and 590,000 tonnes Inferred. Anson Resources (ASX:ASN) expected a JORC resource update covering additional ground during the fourth quarter of 2026, later than previously anticipated. The June 2026 Scoping Study estimated capital costs at about US$569 million, C1 operating costs at US$3,837 per tonne of lithium carbonate equivalent, post-tax net present value of US$896 million at an 8 per cent discount rate and post-tax internal rate of return of 21.7 per cent. These are study estimates, not realised financial performance; the plant layout has subsequently changed.

Incentives and development relationships

Anson Resources (ASX:ASN) identified Utah incentive arrangements totalling approximately US$406.5 million, including US$194.0 million through an industrial property programme and approximately US$212 million in tax credits. The company stated that the incentives become payable only after the facility is operating, so they cannot be treated as cash available to finance construction today. It also reported receiving a first US$2.7 million instalment of a facilitation fee from POSCO, equivalent to about A$3.85 million, leaving approximately US$2.5 million outstanding. POSCO's demonstration plant is planned to operate in 2027 under an agreement running until December 2028.

Cash position and conditional commercial interest

Cash at 30 September 2026 was A$3,461,181, compared with A$3,308,548 at 30 June. Net operating cash inflow of A$170,251 was attributed to the facilitation-fee receipt; exploration and evaluation expenditure totalled A$1,594,412. Anson Resources (ASX:ASN) said its feasibility programme and pre-development expenditure would require further funding. A separate non-binding memorandum contemplates lithium carbonate equivalent supply of roughly 2,000 to 6,000 tonnes per year from around 2029 or 2030 alongside possible financing. Neither binding delivery volumes nor committed project finance were established through that memorandum.

Near-term study programme

The company expects further flowsheet engineering and an iron-removal unit for demonstration activities by the end of 2026. At its Yellow Cat uranium-vanadium project, the report described initial 2026 aircore results as weak and sub-economic, with further assay results expected in early 2027. For Anson Resources (ASX:ASN), the major development sequence remains resource updating, completion of the Green River feasibility study and securing funding before any construction decision.

Key Insights

Anson Resources (ASX:ASN) has advanced Green River's regulatory position, while its 2026 financial and technical disclosures indicate work remains before development can proceed. The distinction between approvals, contingent government incentives, non-binding commercial proposals and financing commitments is material to the project timeline.
