The RK Lithium Project is located in Thailand, the largest EV producer in Southeast Asia and one of the lowest cost operating environments in the world. All required infrastructure is readily available.
The RK Lithium Project (‘RKLP’) includes the RK Lithium Prospect (RK), the BT Lithium Prospect (RK), KT East Lithium Prospect (KT East) and the KT West Lithium Prospect under application.
Flagship Minerals retains a 100% interest in the Project.
RKLP is a hard rock lithium project with lithium hosted in lepidolite/muscovite rich pegmatites chiefly composed of quartz, feldspar, lepidolite and muscovite – both lithium bearing micas – with minor cassiterite and tantalite as well as other accessory minerals. Previous open pit mining extracting tin from the weathered pegmatites was conducted into the early 1970’s.

The RK Lithium Prospect (RK) is located about 8km south of the BT Lithium Prospect (BT) in southern Thailand. At RK ASX:FLG has estimated a Mineral Resource Estimate of 14.8 million tonnes at a grade 0.45% Li2O, containing 164,500 tonnes LCE.
The RK Prospect hosts a relatively large open cut tin mine that operated into the 1970’s. The old pit is about 500m long and up to 125m wide. Mining of weathered pegmatites was undertaken by open cut hydraulic methods to about 30m below surface and ceased when hard rock was intersected.
Mineralisation remains open along strike to the north and south, with strong mineralisation particularly evident at surface and at depth in the south.
The BT Lithium Prospect (BT) is located about 8km north of the RK in southern Thailand. At BT PAM has estimated a drill supported Exploration Target of 16 to 25 million tonnes at a grade ranging between 0.4% to 0.7% Li2O based on 28 diamond drill holes. See Table 2 and PAM ASX announcement “Reung Kiet Lithium Project Exploration Target Substantially Increased” dated 10 July, 2023. Since generating the Exploration Target PAM has completed a further 19 drill holes and there is sufficient drilling to report a Mineral Resource Estimate.
The potential quantity and grade of the Exploration Target are conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The BT hosts a significant historic tin mine that extends for almost 2km along strike. Mining of weathered pegmatites was undertaken by open cut hydraulic methods to about 40m below surface and ceased when hard rock was intersected.
Pantanillo is an oxide gold project located in the Maricunga Gold Belt (MGB), which hosts ~100Moz Au. Gold majors Barrick, Newmont, Kinross and Goldfields present. Pantanillo has a 47.4Mt at 0.69g/t for 1.05Moz Au MRE (NI 43-101) supported by ~20,500m of drilling, and is open up and down dip, and along strike.
At Rosario Flagship is targeting oxide copper. Rosario has 15km of strike across three zones. The eastern zone is interpreted to be 20-200m wide with assays up to 8.9% Cu. 100 non-selective rock chips and channel samples average 2.16% Cu and 12g/t Ag (0.1% cutoff) and 3.15% Cu and 18g/t Ag (0.75% cutoff).
RK is a hard rock lithium project located in Southern Thailand. The project has an MRE, ~165kt LCE, and positive metallurgy. The MRE relates to 1 of 3 prospects, the other two prospects are supported by strong drilling and geochem results. As Thailand is Southeast Asia’s largest EV producer, RK has strategic value.
