rare earth....,

Afghanistan Geological Survey | "In Afghanistan rare metals (lithium, caesium, tantalum and niobium) occur in three main deposit types: pegmatites, mineralised springs and playa-lake sediments" "Globally, rare metals are produced from deposits in these three settings, chiefly in Chile, Argentina, the USA and Turkey. ..

Lithium has many uses, for example in batteries, in the glass and ceramics industry, and in high performance alloys for aircraft. Most tantalum is used to produce capacitors that are used in laptop computers, mobile phones and digital cameras. Niobium is primarily used in specialist steels although it also shares some uses with tantalum since it has almost identical chemical properties.

Conclusions and potential

Afghanistan has considerable resources of rare metals in pegmatites, mineralised springs and lake-sediment salts. No systematic modern exploration has been carried out since the withdrawal of Soviet forces and many of the known localities warrant further investigation and exploration based on modern mineral deposit models and techniques."
In the unlikely - though possible event - that there was any confusion concerning why I deemed this article post-worthy
China mines over 95pc of the world’s rare earth minerals, mostly in Inner Mongolia. The move to hoard reserves is the clearest sign to date that the global struggle for diminishing resources is shifting into a new phase. Countries may find it hard to obtain key materials at any price.
Resource nationalism and piracy are topics worthy of a little extra vigilance.
