Jindalee is also pleased to announce an independently estimated Exploration Target Range (ETR) at McDermitt. The ETR of 300 – 700 Million tonnes at 1,100 – 1,400ppm Li (at 1,000ppm Li cut-off) is extrapolated from drilling completed at the Project (Table 1, Figure 1).
Table 1 – Summary of Exploration Target Range at cut-off of 1000ppm. LCE calculated using the midpoint of the range.
Recent relogging of McDermitt drilling, combined with regional mapping and sampling, has recognised up to 12 distinctive and laterally continuous stratigraphic units which can be tracked across the Project area. The Exploration Target surrounds and abuts the 2023 MRE and is extrapolated from 62 holes drilled at McDermitt from 2018 to 2022. Material for the MRE extends to a maximum distance of 1,200m from the nearest hole, with the ETR extending to a maximum of 1,500m from the nearest hole (Figure 1).
In August 2022 Jindalee submitted an Exploration Plan of Operations (EPO) to the Bureau of Land Management (BLM), with the EPO deemed complete by the BLM in May 20232. Once approved, the EPO will allow Jindalee to significantly increase on-site activity, including up to 160 holes designed to both infill the 2023 MRE and test areas currently covered by the Exploration Target. Jindalee expects the EPO to be approved 2H 2024, with drilling to commence soon after.
Furthermore, sampling of weathered sediments exposed in drainages west and south of the Mineral Resource and Exploration Target areas has returned strongly anomalous lithium values, indicating excellent potential to locate additional lithium mineralisation in these areas (Figure 1, Table 2).

Methodology
The methodology used for the ETR was identical to that used for the 2023 MRE1. A total of 62 drillholes and 97 density measurements were used for the estimation of both the 2023 MRE and the ETR, with lithium estimated by Ordinary Kriging. The block size for estimation was 200mE by 200mN by 5mRL, with sub-celling permitted to 40mE by 40mN by 1mRL.
The ETR estimates were guided by stratigraphy, which is the major control on the continuity of both lithium grade and geology, with material for the ETR limited to within 1,500m of the nearest hole. The entire mineralisation inventory (2023 MRE and ETR) occurs within 215m of surface.
A summary of all drill data included in both the 2023 MRE and the ETR is included in Annexure A. All other details pertaining to the reporting of exploration results and the 2023 MRE and the ETR are detailed in Annexure B.

Paynes Find (Li) Project

Golden State’s Managing Director, Michael Moore commented: “Despite the very limited fieldwork coverage thus far, GSM has already validated its original targeting criteria at the Paynes Find lithium project – a self-generated asset in the greater Murchison region of Western Australia.
These encouraging results come from a recent field trip which identified outcropping pegmatites and further enhanced the prospectivity of the project. This data provides the basis for a robust drilling campaign in 2024.
GSM looks forward to carrying out further fieldwork during this quarter, assisting drill-hole placement, target vectoring and updating shareholders as work progresses.”
Paynes Find (Li) Project
GSM has received assay results for 18 rock chip samples collected from a range of pegmatite outcrops at the Paynes Find North (Figure 1) and Paynes Find Central project areas (refer to ASX announcement dated 8 November 2023). These results were taken from a preliminary reconnaissance field mapping exercise only with no comprehensive sampling undertaken. The sampled rock chip locations were selected within areas previously highlighted by soils anomalous in lithium (Li), rubidium (Rb), caesium (Cs) and other lithium pathfinder elements (refer to ASX announcement dated 13 June 2023). A results table of significant elements and key element ratios is provided in Appendices 1 E 2.

Paynes Find North (E59/2660, 2661, 2662 E E59/2701)
At Paynes Find North, assay results for seven rock chip samples returned several highly encouraging results with significant lithium, rubidium and caesium values along with elevated tantalum and niobium. The best result was reported from rock chip sample PFNR016, which recorded a lithium assay approaching an ore grade of 4,170ppm Li (0.9% Li₂O), 2,650ppm Rb (0.29% Rb₂O) and 178ppm Cs. This sample (Figure 2) was collected from a weathered pegmatite sub-crop approximately 3 metres wide with a very coarse-grained K-feldspar-muscovite with opaque quartz pegmatitic mineral assemblage trending approximately 110 degrees east-southeast.

Highlights
The Mt Dove project is located approximately 25km NNW of Mineral Resources’ (ASX: MIN) Wodgina Lithium Mine, 34km WNW of Pilbara Minerals’ (ASX: PLS) Pilgangoora Lithium Mine, 12km SE of De Grey Mining’s (ASX: DEG) Hemi gold deposit, 45km SW of Wildcat Resources’ (ASX: WC8) Tabba Tabba lithium deposit and 41km SSW of Industrial Metals’ (ASX: IND) Pippingarra lithium prospect in the Pilbara region (see Figure 1).
Managing Director and CEO, Neil Marston commented,
“The Mt Dove in-fill soil sampling program has confirmed seven broad areas of lithium and associated pathfinder element anomalism, highlighting the exciting lithium potential of the project.
“Flynn has recently commenced an accelerated work program on its Mt Dove, Lake Johnston and Forrestania lithium projects in Western Australia.”
“The projects are located close to world class lithium deposits and some exciting new discoveries including the Tabba Tabba and Pippingarra projects in the Pilbara and the Burmeister, Jaegermeister and Mt Gordon prospects in the Lake Johnston region.
“The aim of our fieldwork has been to identify pegmatite bodies across our tenements from mapping, sampling and target generation for drill testing. We look forward to providing updates to shareholders on our exploration progress including the plans for our first drill program.”

Soil Sampling Program
The results from an in-fill soil sampling program at the Mt Dove project (E45/5055) have been received and have outlined seven high priority coherent lithium anomalies with associated pathfinder geochemistry and eleven lower priority, less coherent lithium anomalies (Figure 2). The program has been successful in confirming and enhancing the seven high priority lithium geochemical anomalies and in providing further detail of the pathfinder zonation trends (refer to Table 1 and Appendix 1 for further details).
The seven high priority anomalies reveal broad areas of lithium soil anomalism extending between 600m and 3,100m in length and between 200m and 1,000m in width. The soil anomalies have been defined by clusters of samples which are greater than 75ppm Li (+160ppm Li2O) for the original UFF samples and greater than 21ppm Li (+45ppm Li2O) for the recent -2mm soil samples. These are considered significant anomalies particularly when taking into account the supporting associated pathfinder anomalism and trends (Figures 5 - 9).
