The Company has developed a specialized flotation technique tailored to the unique properties of Sangdong’s tungsten ore through a tireless number of lab-scale and continuous process tests at the Korea Institute of Geoscience and Mineral Resources (“KIGAM”). Scaling up this process required further verification on a larger scale. The pilot plant trial production was crucial not only for identifying potential challenges in the main plant but also for acquiring operational expertise prior to full-scale production.
Therefore, prior to the processing plant's construction, tungsten ore from the Sangdong Mine was processed at two pilot plants, each representing 1/500th the size of the actual plant. The pilot plant trial production was conducted at two locations—Portugal during September, 2023 and the Sangdong mine during July and August, 2024 —validating the stability of the Company’s proprietary flotation processing technology.
These tests were carried out at the National Laboratory for Energy and Geology (“LNEG”) in

Based on these results, the Company and its equipment supplier Metso Outotec are now comfortable to sign off on the processing having met all the design performance parameters. Additionally, the tests at Sangdong Mine confirmed the potential to reduce reagent usage while maximizing efficiency.
Mr Lewis Black, Chairman, President and CEO commented: “With the successful completion of the pilot plant phase, all preliminary preparations related to process technology development and equipment performance validation have been finalized. With minor adjustments to the equipment and reagents at the processing plant currently under construction, we anticipate stable production of tungsten concentrate from our Sangdong Mine during 2025. The time we have spent building and operating two pilot plants in
