Pan Asia Metals confirms ‘exceptional’ ore sorting testwork results at Reung Kiet Lithium Prospect, Thailand

Pan Asia Metals (ASX:PAM) reports it has confirmed ‘exceptional’ ore sorting testwork conducted on drill core samples from the Reung Kiet Lithium Prospect in Thailand.

The company says ore sorting is a ‘simple’ and ‘low cost’ process that can facilitate in upgrading mineralisation and rejecting ‘low grade’ and waste material, and modern ore sorting has been employed for about 30 years with recent improvements in technology and sorting sensors combined with rapid data processing speeds has allowed for large scale sorting to be undertaken.

The company has also witnessed a significant increase in its share price on the ASX, jumping 11.627% to $0.480 as of 8am AWST.


In the current testwork program being conducted by Pan Asia, the ore sorting sample is from drillhole RKDD006 and comprises half HQ core (63mm diameter) for the interval 54.5m to 81.5m, and the total sample weight was around 107kg. This core was crushed at Nagrom in Perth and sized to less than 50mm and over 25mm, as well as less than 25mm and over 10mm, and a less than 10mm fines product was also produced.

The crushed core sample was tested at Steinhart Australia’s Test Centre in Perth, and after theoretical modelling the crushed samples were fed in a single-pass and subjected to 3D laser scanning and colour camera sensors used in combination which produced ‘excellent’ separation of the mineralised aplo-pegmatite from the ‘low-grade’ to waste siltstones.

Pan Asia Metals Managing Director Paul Lock says these results confirm Steinhart Australia’s ore sorting testwork can almost double the feed head grade to the beneficiation plant to 0.92% Li2O.

“This means we will be processing a higher grade ore than that reflected in our mineral resource, which is a fantastic outcome as it also means that we will see a reduction in capital and operating costs on a per tonne LCE basis as we will require less beneficiation capacity, lower capex, and we will be processing less product.

“This means we will be processing a higher grade ore than that reflected in our mineral resource, which is a fantastic outcome”

We have more results coming through and I am pleased to say that Reung Kiet is proving its place in the global peer group, particularly so as the project is so well placed in terms of proximity to inputs and markets and the fact that Southeast Asia is one of the lowest cost operating environments in the world.”

Pan Asia reports the data indicates that the sorted less than 50mm and over 10mm pegmatite product and mixed less than 100m fines samples constitute 39.24% of the sample yield with 72.79% of the contained lithium at an average grade of 0.92% Li2O.

Conversely the siltstone reject constitutes 60.76% of sample yield but only 27.21% of contained lithium at an average grade of 0.22% Li2O, which was below the current mineral resource cut-off grade of 0.25% Li2O, and these results are almost identical to previous estimates reported early this month.

The company says this testwork demonstrates the sampled mineralisation is ‘highly amenable’ to ore sorting which results in the separation of the material into a homogenous aplo-pegmatite with little siltstone contamination and siltstone with little pegmatite, and the pegmatite contains the bulk of the lithium mineralisation.

Floatation testwork is now being undertaken on the sorted products, and additional ore sorting testwork will also be undertaken on more drillholes.

Pan Asia Metals is a battery and critical metals explorer and developer focused on the identification and development of projects in Asia that have the potential to position the company to produce metal compounds and other value added products in high demand.

The company owns the Reung Kiet Lithium Project, the Kata Thong Lithium Project and the Khao Soon Tungsten Project all located in Thailand.
