Anson Resources Ltd (ASX:ASN) has delivered a material increase of up to 70% in lithium brine assays with drilling in the Clastic Zones of the Long Canyon No.2 well at the Paradox Lithium Project, in Utah, USA.
This up-tick in lithium grades follows an 87% increase from just last week, when Anson fast-tracked assays from this newly tested area.

The latest lithium and bromine assays (in parts per million or ppm) from Long Canyon No.2 include:
- 103ppm lithium, 1,940ppm bromide and 662ppm boron in Clastic Zone 33 (11 feet thick);
- 189ppm lithium, 3,576ppm bromide and 1,131ppm boron in Clastic Zone 29 (18 feet thick);
- 191ppm lithium, 3,862ppm bromide and 1,123 boron in Clastic Zone 19 (38 feet thick); and
- 126ppm lithium, 2,504ppm bromide and 760ppm boron in Clastic Zone 19 (46 feet thick)
From these results Anson has interpreted lithium grades to increase from north to south within the project area, offering a deeper understanding of the brine characteristics at Paradox.
Confident of JORC upgrade
Given the large increases in brine assays, Anson is now confident it will deliver a JORC-compliant upgrade to its indicated and inferred resource, which will include resources from:
- the thicker Mississippian Units (187ppm lithium, 3,793ppm bromine);
- Clastic Zones 17, 19, 29 and 33 not included in the existing Paradox Resource; and,
- there is also potential for further resource expansion via targeted drilling in the western areas of the project.
The company intends to include this resource upgrade in a definitive feasibility study (DFS), which is in the works.
