Maiden lithium resource incoming: Anson eyes free flowing brines from Green River re-entry program
Link copied to
Anson is moving to start resource definition drilling at its Green River lithium project in Utah’s Paradox Basin to deliver a maiden JORC Resource.
A recent review of research and surveys of the project already highlighted the potential for brine flows to surface from porous Mississippian units without pumping, a feature shared with its nearby Paradox lithium project.
Under the Notice of Intent (NOI) filed with the US Bureau of Land Management, Anson Resources (ASX:ASN) plans to re-enter three historical oil and gas wells with brine sampling and pump testing on the targeted clastic zone horizons and the Mississippian units.
Drilling is expected to begin once the NOI has been accepted and the program may be extended if deemed necessary.
Green River covers a 106.2km2 area and is known to host the 15km by 16km Ten Mile Graben, which is structurally similar to the ‘Roberts Rupture’ at the Paradox project only 50km to the southeast.
Ten Mile Grabben hosts numerous saltwater geysers and springs, which is indicative of extreme fracturing and increased porosity of the host rock units.
Anson’s research has thus far focused on reviewing data from numerous historical oil and gas wells, which have provided a large database of information that is expected to reduce costs of exploration and shorten the time frame to complete mineral resource calculations.
Drilling records indicate that the targeted geological units at Green River are continuous from the nearby Paradox Project and have similar properties.
Notably, drilling of the Mississippian units has resulted in brine flowing to the surface at Green River, which did not occur at the Paradox project.
This has the potential to reduced operating costs as it eliminates the need for mechanical pumping to extract brines from depth.
The re-entry program will use existing drill pads close to existing roads to minimise new ground disturbance and eliminate the need to establish new access routes.
