• Anson Resources secures approvals to start resource drilling at its Green River lithium brines project
  • First well will sample the Mississippian Units and Clastic Zones for their lithium potential
  • Recovered core will also be tested in the laboratory to help determine a maiden resource for Green River


Special Report: Anson Resources has received the green light to start resource drilling at its Green River lithium brines project in Utah’s Paradox Basin with all regulatory approvals now in place.

Green River is a potentially large project, with a conceptual exploration target of between 2Bt and 2.6Bt of brines grading 100ppm to 150ppm lithium and 2,000ppm to 3,000ppm bromine.

Early work has indicated that lithium-rich brines at the 106.2km2 project could flow to the surface naturally, which could reduce operating costs by eliminating the need for mechanical pumping to extract brines from depth.

Anson Resources (ASX:ASN) intends to develop Green River in parallel with its flagship asset, the nearby 1.038Mt LCE Paradox lithium project about 50km southeast.

Both projects have similar geological, metallurgical and structural characteristics.

It is also progressing construction of the Utah sample demonstration plant (USDP) that will initially produce 500kg of battery-grade lithium carbonate per annum.

Drilling to define resources

With the approval of the Notice of Intent and grant of the Application Permit to Drill from the Utah Division of Oil, Gas and Mining (UDOGM), Minerals Division, the company can now proceed with the first phase of drilling aimed at defining resources for the Green River project.

Drilling is planned to a depth of ~3,292m and will sample the Mississippian Units and Clastic Zones – both of which have been previously recorded to host supersaturated brines though no sampling for lithium has been done.

The first well, Bosydaba 1, will be located next to the USDP, at a site on the company’s recently acquired industrial-use, private property that requires minimal earthworks before drilling begins.

ASN intends to sample the target horizons for their lithium content, a process that also enables coring to be carried out on major horizons of interest.

The recovered core will be used for laboratory work to determine data such as specific yield that will be used to determine a maiden resource for Green River.

Additionally, the well location allows for brine to flow directly to the USDP, allowing the plant to be operated 24/7 to produce a high purity lithium carbonate product.
