The Jiangxi Daily (江西日报) carried a puff piece last week devoted to the aforementioned Bureau (江西有色地质勘查局), who have been exploring for copper, zinc and lead at Jiangxi Copper’s Wegener Halvø site, near Ittoqqortoormiit in eastern Greenland since 2011. The article also mentions the Bureau’s activities in tantalium and niobium exploration, both domestically and in Shakiso, Ethiopia, where a company from Jiangxi (or a duplet of closely connected companies, viz. King-Tan/Kingtai/Jingtai 江西景泰钽业有限公司 and ZCXC/Zhicheng 江西智诚新材料科技有限公司) has been active for some time.
There is both tantalum and niobium in Greenland, e.g. at Ram Resources‘ Motzfeldt Sø project in the south, at NunaMinerals’ Qeqertaasaq rare earth + Nb project near Nuuk, where Korean state-owned miner KORES (한국광물자원공사) has already shown interest, and in Kap Simpson, in an area where Czech company CGRG holds an exploration license, just across from Jiangxi Copper’s Wegener Halvø project. China has a high demand for tantalum and niobium, and Chinese companies have been acquiring stakes in Ta/Nb mines abroad, so it would make sense for them to look for it in Greenland as well.
