High Grade Lithium ‘Sweet Spots’ Identified at Utah Lithium Project
Highlights
-
The 100%-owned Utah Lithium Project hosts an Inferred Resource estimate of 3.3Mt Lithium Carbonate Equivalent (LCE) [1]
-
Brine Flow Modelling Study has identified two potential discrete zones of high lithium concentrations (‘sweet spots’) within the prodigious Leadville Formation
-
High lithium concentration sweet spots largely overlap with high quality reservoirs characterized by enhanced permeability and elevated net pay thicknesses determined by core analyses and drill-stem tests on existing wells
-
Sweet spots represent compelling targets as they incorporate several existing wells that can be re-entered and tested at low cost – access negotiations underway
-
Brine Flow Modelling Study also identified potential high-grade bulk lithium brines in the Paradox Formation similar to the worldclass Smackover Formation with Paradox brine sampling containing significant lithium concentrations up to 340mg/L[2]
Mandrake Resources Limited (ASX: MAN) (Mandrake or the Company) is pleased to announce the results of the comprehensive Lithium Brine Flow Modelling Study at the 93,755 acre (approximately 379 km[2] ) 100%-owned Utah Lithium Project in the Paradox Basin.
Managing Director James Allchurch commented:
‘The comprehensive Lithium Brine Flow Modelling Study was undertaken by a leading team of technical consultants utilizing a series of existing advanced datasets including 3D seismic, petrophysical well logs and corresponding drill core, lithium brine chemistry and detailed well files.
The Study has identified two distinctive high-grade lithium brine sweet spots incorporated within Mandrake’s project area which coincides with zones of enhanced permeability and elevated net pay thickness in the Leadville Formation.
The sweet spots constitute a compelling opportunity for re-entry and testing of existing wells. Mandrake is currently negotiating well access with operators in the area.’

Brine Flow Modelling Study
Mandrake has now completed the various work streams required to create a conceptual model of 2D lithium brine flow designed to assist with exploration targeting.
The comprehensive brine flow model has incorporated the following (Figure 1):
-
Core-based porosity/permeability and flow-test permeability trends
-
Fault geometries from 3D seismic and well data
-
Regional lithium brine chemistry trends – Leadville and Paradox Formations
-
Potentiometric surfaces for brine flow directions and migration duration
-
Petra[®] -generated maps and cross sections
The model has greatly enhanced exploration at the Utah Lithium Project through the identification of zones of high-grade lithium brine within the Leadville Formation whilst also generating a reliable potentiometric vector map detailing brine flow direction, and relative brine-migration-duration within the Leadville Formation.

Permeability Analysis
Permeability data for the Leadville Formation was derived from core plug analyses in eight wells and from DST results compiled by Teller and Chafin (1986)[3] , which was digitized by Mandrake’s team. Within the mapping area, a total of 17 Leadville wells were utilized to generate a geometric mean permeability grid.
Results indicate that areas with complex faulting - including fault intersections, re-activated horst and graben systems, and fault terminations - show enhanced Leadville permeability. This is most likely due to hydrothermal fluid flow along the faults resulting in increased dolomitization. Permeability values decrease progressively to the east outside of the Utah Lithium Project, consistent with regional depositional trends and with mapped Leadville net pay and thickness.
Some areas of enhanced permeability are also characterized by elevated net pay thicknesses, and a long brine flow path from the northeast, indicating large volumes of highly permeable reservoir rock in an area identified by potentiometric mapping and lithium concentration distribution analysis as containing elevated lithium brine concentrations (sweet spots) (Figures 2-3).

Figure 2. Southwest to northeast cross section A-B highlights log porosity (green) and permeability from core data (see Figure 3 for A-B location). Net pay trends increase to the SW as the Leadville thickens and more porosity is developed. Permeability is best developed near complex faulting. Brine flow in the Leadville is from the NE to the SW.

Basement and Potentiometric Mapping of Leadville Brines
Dissolved lithium within Leadville Formation-hosted brines is likely to have been sourced from connate water which has strongly interacted with radiogenic, high[87] Sr/[86] Sr, crystalline Precambrian basement.
Other authors studying radiogenic isotopes and dissolved noble gasses (e.g. Kim et al., 2022, Tyne et al., 2022)[4] ,[5] also support this concept of basement lithium sourcing and further demonstrate the clear geochemical separation between the underlying Mississippian Leadville and the overlying Pennsylvanian Paradox Formation.
Leadville brines that have interacted multiple times over prolonged periods with faulted/fractured basement are likely to have higher lithium concentrations due to enhanced brine–basement interactions and incorporation of soluble lithium into brines.

Comprehensive potentiometric brine flow mapping of the Leadville was achieved through the painstaking compilation of detailed time-pressure tests, drill stem tests (DSTs) and shut-in tests gleaned from the well files of hundreds of historical wells across the study area.
The resulting potentiometric brine flow map demonstrates distinct zones of brine influx and shows brine-flow directions within the Leadville. Lithium in the Leadville is sourced from the underlying basement, and lithium concentrations are expected to be highest where brines have had the longest residence time and most extensive basement–fluid interactions. Based on the brine flow map, areas in the southwest of the project area are interpreted as priority targets, or ‘sweet spots’, for elevated lithium brine concentrations (see Figure 3).
Paradox Formation Clastic Units – Lithium Concentrations up to 340mg/L
==> picture [222 x 344] intentionally omitted <==
Detailed modelling and assessment of the Paradox Formation has identified the potential for high-grade bulk lithium brines hosted within the constituent clastic zones. The Paradox Formation was deposited during the Pennsylvanian Subperiod in a restricted marine and salt evaporate basin that covered southwest Utah. The formation consists of 29 separate salt cycles interbedded with shales, sandstones, anhydrites and dolomites.
Mapping, interpretation and petrophysical analyses focusing on over 22 oil and gas wells within the project area has demonstrated an aggregate clastic net pay thickness[6] of 59m within the Paradox Formation. This demonstrates the significant potential for large-scale high-grade lithium brines hosted within the Paradox Formation, comparable to world-class lithium brine precincts of the Smackover Formation and Lithium Triangle of South America.
Figure 4 (left). Stratigraphic column showing clastic units and zones within the Paradox Formation. Note Zones A and B historically have returned high concentrations of lithium within brines.
Based on stratigraphic trends, Li concentration, and the major-cation balance within Pennsylvanian brines of the Paradox Basin, the clastic units were divided into Zones A (clastic units 5 to 10), B (clastic units 11 to 20) and C (clastic units 21 to 29) (Figure 2).
6 To qualify as ‘net payable thickness’ clastic material within Zones A and B must have porosity above 6% and shale volume below 70% as according to standard petrophysical log analysis of oil and gas wells across the project. The net pay cutoff ensures that non-productive clastic material is not captured in brine volume projections

Clastic units 5 to 20, Zones A and B, within the Pennsylvanian-aged Paradox Formation, have been identified as highly prospective for lithium brines, with historical lithium concentrations of 340 mg/L from the Peterson 88-21 well and Mandrake sampling from 2024 recording 147 mg/L at the Big Indian # 1 well.
Summary and Next Steps
The Brine Flow Modelling Study has identified sweet spots within the Utah Lithium Project area that exhibit enhanced permeability and elevated net pay thicknesses within the Leadville Formation. Further, the sweet spots largely coincide with areas identified by brine chemistry analysis and potentiometric mapping as priority targets for elevated lithium brine concentrations.
Existing suspended and depleted oil and gas wells within the sweet spot areas have been reviewed as potential candidates for re-entry to facilitate flow/pressure testing and chemical analysis of brine. Negotiations with operators of existing wells within the areas have commenced together with the formulation of well work-over plans by third party consultant engineers.
