RK Lithium Project - KT East Lithium Prospect

Abundant Lepidolite Pegmatite Zone Identified – 1.5km x 500m

Battery and critical metals explorer and developer Pan Asia Metals Limited (ASX: PAM) (‘PAM’ or ‘the Company’) is pleased to report that field work at the KT East Lithium Prospect continues to deliver strong results and expand the potential for the prospect.


  • Rock-chip sampling continues to enhance prospectivity
  • Zone of abundant lepidolite pegmatites 1.5km long and 500m wide define
  • Individual dykes up to 20m wide, many 7-10m wide, ranging down to 1m or less
  • Old mine dumps containing extensive lepidolite pegmatite enhance potential to north
  • Hand held XRF (hhXRF) of rock-chip samples return highly elevated Li pathfinder elements such as rubidium (Rb) and ceasium (Cs)
  • Modelled Li2O grades using Rb regression are supported by the presence of lepidolite and white mica in many samples
  • KTE prospect has larger footprint than the RK and BT Lithium Prospects combined
  • Soil sampling on 100m x 25m grid has begun, with associated rock-chip sampling and mapping
  • Preliminary drill sites identified, several walk-up targets identified, many more sites to assess
  • Drilling scheduled for later this year

Pan Asia Metals’ Managing Director, Paul Lock, said: “The KT Lithium Prospect is proving to be extensive, and the Li2O mod grades continue to impress. PAM’s field team has begun a grid-based soil and rock-chip sampling and geological mapping program, with soil sampling being conducted on a 100m x 25m grid. Initial gridding reports have been very encouraging, and we await formal results before providing an update on the program in a week or so. We are also investigating drill sites, with several walk-up drill targets identified. Drilling is expected to start later this year. KT presents PAM a substantial extension to RK and BT prospects and, with the KT footprint already larger than RK and BT combined, KT has the potential to add substantial tonnes, which means potential for an extended project life and/or increased annual LCE production. These results are feeding into discussions with strategic partners, so the KT exploration success is timely.”

PAM is pleased to provide this update as its field team continues its exploration program at the KT East Lithium Prospect. This highly prospective zone continues to deliver, with additional pegmatites discovered during the ongoing rock-chip and mapping program. This update follows on from PAM’s recent ASX announcement dated May 22, 2024 and titled “RK Lithium Project - KT East Lithium Prospect Lepidolite Pegmatite Dyke Swarm – Discovery Footprint Expands”. The lithium pegmatite field is identified over a strike length of approximately 2.4km and a width of at least 2.4km

The pegmatite dyke swarm remains open and is now larger than the aggregate area of the RK and BT Lithium Prospects combined. Additional pegmatites, or extensions to previously mapped pegmatites, have been discovered, and the field team identified a historic alluvial/eluvial dump, remnants from historic tin mining, where rock-chips grading 1.74% and 1.64% Li2O mod were taken. The dump is about 70% Lepidolite pegmatites (see Figure 1 and Picture 1). Other dumps and samples are also located immediately to the west.

In this report, sample details and pertinent hhXRF results are presented in Appendix 2 – “Table 3, KT East Lithium Prospect – hhXRF Rb and Li2O% mod”. Further technical details are provided in Appendix 3, being JORC Table 1. Appropriate plans are provided in this report.

Rock-chip sampling and mapping has been conducted within the KT East prospect area, collecting samples of outcrop, subcrop and float for analysis. Most of these samples are described as pegmatite, with varying amounts of lepidolite and white mica. Many of the samples are described as weathered. Hand-held X-Ray fluorescence analysis (hhXRF) was carried out on an informally powdered sample that reports to the bottom corner of the calico sample bag. Two separate analysis per sample are taken in different locations, with the average result used to report grades. The analysis was performed using an Olympus Delta 400hhXRF in Geochem mode with dual beam analysis for 30 seconds each. The hhXRF reports 43 elements, but not lithium. Reported elements include lithium pathfinders and associated elements such as Rb, Cs, Mn, K, Ba, Sn, Ta and Nb. Rb (rubidium) exhibits a very strong correlation with Li in hhXRF rubidium v laboratory results for Li. This Rb:Li correlation has an R2 of 0.82 based upon 162 previous rockchip samples from the RK and BT prospects (see Appendix 3, Table 1). This technique has been practiced by PAM for many years as an accurate and cost effective means of identifying target zones quickly and efficiently.

The strong Rb:Li correlation enables a regression formula to be used to estimate an Li2O grade, herein referred to as “Li2O% mod”. The regression formula is simplified to 3 x Rb (ppm) = Li2O mod (ppm). The results for Rb and Li2O% mod for new samples (20553-20602) collected at KT East are reported in Appendix 2. The Li2O% mod values of these samples range from 0.01% to 3.06% % Li2O, with an average of 1.14%. Of all 132 samples so far collected at the prospect, 96 have returned values greater than 0.50% Li2O mod, with an average of 1.19% Li2O mod. The Li2O% mod values are supported by other Li pathfinders identified by hhXRF, as well as the presence of variable, but commonly abundant lepidolite and white mica.

Readers are cautioned that the Li2O% mod values reported are estimates of potential lithium grade based upon the strong correlation between Rb and Li, and a simple regression formula applied to hhXRF results for Rb. The derived Li2O% mod values are supported by the presence of lithium micas in the samples tested. Readers should note the Li2O% mod values are not laboratory quality results and actual Li2O contents for these samples await confirmation by laboratory analysis to be undertaken at a later date.

5 Themes from Fastmarkets' 2024 Lithium Supply and Battery Raw Materials Event

Demand for lithium is expected to grow in the next 10 years as electric vehicle proliferation continues and the energy storage sector expands.

While experts are optimistic about the market’s medium- and long-term fundamentals, the current market oversupply and weak EV sales have weighed on prices over the last year.

Although prices have remained subdued through 2023 into 2024, investor interest in the battery metal market has grown, which was evident at Fastmarkets’ 2024 Lithium Supply and Battery Raw Materials conference.

The four-day event saw record attendance, with more than 1,100 attendants and 150 speakers gathering in Las Vegas to learn more about the trajectory of the lithium industry and other key battery raw materials.
