Anson Resources Ltd (ASX:ASN) has increased throughputs by more than 140% while drilling for resource expansion at the Paradox Lithium Project in Utah, USA.
In particular, the artesian flow of supersaturated brine increased by:
- 165% at Long Canyon No. 2 – throughput of 180 barrels of oil per hour; and
- 147% at Cane Creek 32-1 – throughput of 66 barrels of oil per hour.
A key positive result of the greatly improved flow rates is that they are expected to push brine to the surface without the need for pumping.
This would bring substantial benefits to the mining economics and longevity of Anson’s proposed lithium production operation at Paradox.
Resource expansion drilling
Anson’s ongoing resource expansion drilling program at Paradox is focused on the targeted Mississippian units at the Cane Creek 32-1 priority well.
During reentry at Cane Creek 32-1, the Clastic Zone 31 horizon delivered a flow rate of 66 bph, a 147% increase over the initially recorded flow rate at this target.
Similarly, a 165% throughput increase was achieved with Anson’s recently completed drilling at the Long Canyon No. 2 well.
These results indicate that salts that have already precipitated are breaking down over time due to the influx of brine – due to the positive attributes of high pressure, porosity and permeability in the Paradox Project area.

High pressure and increased flow rates
Anson said further test work on the Long Canyon No. 2 and Cane Creek 32-1 wells confirmed continued high pressure and increased high flows.
This is a very positive result that should have a positive impact on the economics of the Paradox Lithium project proposed by Anson.
Anson is in a unique and ideal location for brine extraction at the intersection of the Robert break and the Cane Creek anticline at the Paradox project.
The Robert break provides vertical porosity and the Cane Creek anticline results in shallower depth to the target mining horizon.
The three factors; high pressure, porosity (horizontal and vertical) and shallow depth are key attributes of the Paradox Lithium Project and are not present anywhere else in the region.
Together, they provide strong indicators of low extraction costs and beneficial ESG outcomes.
The wells that Anson has reinstated into its current drilling program have provided artesian flow (i.e., natural flow without the need for pumping) from the Clastic Zone 31 horizon due to higher constant pressures and porosities of this clastic zone.
