Pan Asia Metals extends mineralisation at Reung Kiet Lithium Project in Thailand

Pan Asia Metals (ASX:PAM) reports 11 more drillholes recently completed support the geological model of ‘extensive’ lithium mineralisation at the Reung Kiet Lithium Project in Thailand.

The company says this lithium mineralisation is hosted in lepidolite rich pegmatite dykes and veins and adjacent metasediments, and the mineralised zone is currently defined over a strike length of over 1km, and remind open along strike to the north and south, and at depth on many sections, especially in the south.

The Reung Kiet Lithium Project is described as a hard rock lithium project with lithium hosted in lepidolite and mica rich pegmatites composed primarily of quartz, albite, lepidolite and muscovite with minor cassiterite and tantalite as well as other accessory minerals, and previous open pit mining extracting tin from the weathered pegmatites was conducted into the early 1970s.

Pan Asia states its objective is to continue drilling with the aim of increasing and upgrading the existing mineral resource, which will be used as part of a scoping study that plans to consider initial production of up to 10,000 tonnes per annum of LCE and associated by-products.

The company will be 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, and lepidolite has also demonstrated to have a lower carbon emission intensity than other lithium sources.

Pan Asia Metals Managing Director Paul Lock said: “Another set of pleasing results as we near the end of the drilling program at the Reung Kiet Lithium Prospect.

The step out drilling continues to demonstrate extensions at depth and along strike of the existing mineral resource, which essentially means we can expect more tonnes and an upgrade from the inferred category to indicated and in parts measured categories when the mineral resource update is reported.

We are on track for our 10,000 tonnes per annum LCE for 10 years and our recent work at the Bang I Tum Lithium Prospect provides potential to push through this target.”

At the Reung Kiet Prospect, the company has been conducting drilling here since March 2021, and it has recently received assays for drillholes RKDD062 to RKDD072, and the holes are a mix of infill and extensional drilling, and as means to expedite the assay process only results for lithium are available and elements such as tin and tantalum will be reported at a later date.

On Section R, RKDD068 was drilled from the western side of the pit to test for up-dip extensions of the pegmatite, and on this section, drilling from the eastern side of the pit to test this area is precluded due to pit geometry. In RKDD068 lithium mineralisation was intersected over intervals with an aggregate thickness of 52.65m @ 0.59% Li2O from 28.4m to 97.5m.

As the hole was drilled sub-parallel to the pegmatite dip, true thickness is around 20% of downhole thickness reported, and the intersections in this hole have the potential to extend the mineral resource both up-dip and along strike to the northeast.

On Section Q, hole RKDD069 was drilled from the western side of the pit to test for up-dip extensions of the pegmatite intersected in RKDD001. RKDD069 intersected the main pegmatite commencing at 63.6m and was abandoned in pegmatite at 83.9m, and this zone returned 20.3m @ 0.70% Li2O, and as the hole was drilled sub-parallel to the pegmatite dip, true thickness is around 20% of downhole thickness reported.

Pan Asia reports in Section P, RKDD072 was drilled to test for down-dip extensions to mineralisation intersected in RKDD041. In RKDD072 a 7.65m wide pegmatite was intersected from 214.4m and an 8.35m wide pegmatite from 239.8m and both zones yielded anomalous Li2O generally less than 0.10%, and tin and tantalum results are awaited.

On Section N, hole RKDD071 was drilled as infill between holes RKDD029 and RKDD040. In hole RKDD071 an aggregate mineralised thickness of 31.6m @ 0.52% Li2O was intersected between 8.5m and 118.85m, and these results support and enhance previous results in adjacent holes.

On Section M-N, RKDD070 was drilled as an infill hole and intersected 11.5m of aggregate pegmatite thickness averaging 0.68% Li2O from 21m to 88.8m, RKDD076 intersected pegmatite from 38.7m to 56m with assays awaited, and both these holes support previous interpretations.

The company says in Section K, RKDD062 was drilled as an infill hole between RK011 and RKDD034, and the hole intersected numerous pegmatite dykes and veins from 18.9m to 199.65m for an aggregate pegmatite thickness of 21.7m @ 0.48% Li2O, and some pegmatites contain local zones of lepidolite enrichment supporting adjacent drillholes.

On Section I, hole RKDD063 was drilled to infill between RKDD010 and RKDD012. From 13.2m to 187.7m RKDD063 intersected a swarm of pegmatite veins and dykes with an aggregate thickness of 44.75m averaging 0.52% Li2O including 7.4m @ 0.81% Li2O from 74.3m, and the results from this hole RKDD063 support and enhance results in adjacent holes.

Pan Asia says in Section H, hole RKDD064 was drilled to test for extensions to mineralisation intersected in hole RKDD036, and in RKDD064 numerous pegmatite veins and dykes were intersected from 79.9m to 282.5m, and from 121.55m to 281.55m returned an aggregate thickness of 18.05m @ 0.48% Li2O.

In Section G, drillhole RKDD065 was targeting extensions to mineralisation intersected in hole RKDD013, and RKDD065 intersected pegmatite down-dip of RKDD013 with the main zones occurring from 132.2m to 258m and contained only 5.4m aggregate pegmatite thickness with an average grade of 0.37% Li2O. The deeper pegmatites from 250.9m to 275.5m may also contain tin and tantalum mineralisation, and assays are awaited.

In Section E hole, RKDD066 was drilled to extend mineralisation down-dip of RKDD014 from 72.6m to 265.5m, RKDD066 intersected an aggregate thickness of 42.4m of pegmatite, with 2 main zones of pegmatite concentrations, the first from 180m to 194.2m containing 11.3m aggregate thickness.

A second zone from 230m to 265.5m contains 18.5m aggregate pegmatite thickness, and from 120.8m to 237.7m contained 18.9m of aggregate mineralisation averaging 0.39% Li2O and results in the hole confirms lower grade extensions to mineralisation in RKDD014, and tin and tantalum assays are awaited.

Lastly, in Section D RKDD067 was drilled as an infill hole between RKDD024 and RKDD044 and intersected pegmatite dykes and veins with an aggregate thickness of 49.4m between 63.7m to 258.7m, and the main lithium rich zones occur from 100.4m to 180.35m with 31.9m aggregate mineralisation thickness averaging 0.66% Li2O, including 7.55m @ 0.94% Li2O from 152.6m and 10.8m @ 0.78% Li2O from 169.55m.

A lower zone of pegmatite with an aggregate thickness of 21.6m occurs between 228.05m to 257.9m, and this zone has lower concentrations of mica compared to the pegmatites above and may contain tin and tantalum mineralisation for which assays are awaited.

Pan Asia reports it is continuing to drill at Reung Kiet with the aim of increasing the existing the mineral resource and also upgrading parts of the mineral resource from the inferred to indicated and possibly measured classification, and a mineral resource update is planned for early next year and will aid in the completion of additional project studies.

The company is currently drilling holes RKDD095 and RKDD096 and is awaiting results for holes RKDD073 to RKDD091, and logging and sampling of holes RKDD092 onwards is continuing with a new batch of samples due to be dispatched to the laboratory shortly.

After the completion of drilling at Reung Kiet, Pan Asia says the drill rigs will move to the Bang I Tum Prospect where the company will evaluate the existing exploration target.
