Pan Asia Metals Limited provided initial metallurgical testwork results for flotation recovery of lithium mica concentrates using representative sample from the Reung Kiet lithium prospect. The Reung Kiet Lithium Project (RKLP) is one of PAM's key assets. RKLP is a hard rock lithium project with lithium hosted in lepidolite/mica rich pegmatites chiefly composed of quartz, albite, lepidolite and muscovite, 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. PAM's objective has been to continue drilling with the aim of increasing and upgrading the existing Mineral Resource, which will then be used as part of a Pre-Feasibility Study that will consider various options to determine the technical and economic viability of the project including the LCE production profile as well as associated by-products. PAM is focusing on lepidolite as a source of lithium as peer group studies indicate that lithium carbonate and lithium hydroxide projects using lepidolite as their plant feedstock have the potential to be placed near the bottom of the cost curve. Lepidolite has also been demonstrated to have a lower carbon emission intensity than other lithium sources. The RK Prospect was a relatively large open cut tin mine. The old pit is about 500m long and up to 125m wide. Mining of the weathered pegmatites extended up to 30m below surface, to the top of hard rock. Pan Asia has identified a prospective zone at least 1km long, reporting an Inferred Mineral Resource estimate. The Mineral Resource is based upon the first 46 holes drilled at Reung Kiet. Ongoing drilling has seen the completion of an additional 54 holes, most of which will be included in the Mineral Resource update which aims to increase the Mineral Resource tonnage and upgrade portions of the Mineral Resource from Inferred to Indicated and possibly Measured classification. The testwork was conducted on two separate composites comprised of fresh and weathered mineralisation derived from laboratory `coarse crush rejects' (100% <3.35mm) from ½ HQ sized drill core selected from drillholes (orange drill collars). The fresh composite sample weighed approximately 125kg and was derived from 278 individual samples from 16 holes. This sample returned a head assay of 0.62% Li2O. The oxide composite weighed approximately 100kg, derived from 133 individual samples from 11 holes. It returned a head assay of 0.77% Li2O. The samples were selected to represent mineralisation throughout the deposit and reflect what are considered to be mineable widths in a potential open cut mine. Therefore, the samples contain both internal and external dilution predominantly composed of low-grade siltstone. The samples were delivered to the technology division of Beijing General Research Institute of Mining & Metallurgy (BGRIMM) in China. BGRIMM has particular experience and expertise regarding metallurgical aspects of lithium mica `lepidolite' deposits in China. The testwork was overseen by Dr. Evan Kirby of Metallurgical Management Services, a metallurgist with over 45 years experience in minerals testing and feasibility work, including several assignments with BGRIMM. China is the only jurisdiction where lithium chemicals are being commercially produced from lepidolite `ores'. The Hard Rock LCE Cost Curve below uses data compiled by Wood Mackenzie (Asia Pacific) Pte. Ltd. (WM) for Tianqi Lithium Corporation. It demonstrates the cost competitiveness of lepidolite as a source of LCE and that China produced approximately 50,000t of LCE from lepidolite in 2021, representing about 18% of global hard-rock LCE production. Benchmark Intelligence recently stated. BGRIMM carried out extensive process mineralogy and beneficiation research and
testwork on the samples provided by PAM. The research included ICP spectrometry, chemical composition analysis, mineral composition and relative content determination, characteristics and grain size of the main lithium minerals, study of the occurrence state of lithium, study on the association and separation characteristics of main lithium minerals in different grinding products, analysis of mineralogy factors influencing lithium recovery. Beneficiation research and testwork included acid-base process scheme comparison
tests, flotation tests using different grind sizes, contrast tests for desliming and not
desliming, and different desliming quantities, type and amount of reagents/conditioning tests, type and amount of collector tests, flotation time tests, flotation tests for the regrinding fineness, tests for cleaning conditions, rougher concentrate screening analysis, classification and separation test for rougher concentrate, several open circuit process comparison tests and closed circuit tests. The technical means and instruments used in this study included chemical analysis, optical microscopy, scanning electron microscopy, electron micro-probe analysis, Advanced Mineral Identification and Characterization System (AMICS) and other applicable measures.
