Description FirstLink Investments hopes to prove it's worth its salt. Formerly named Singatronics, the investment firm has labeled many of its operations as "discontinued" and is now primarily engaged in the mining, processing, and distribution of salt. Through subsidiary Amtrosden Assets Limited, previously part of former subsidiary Green Salt Group, FirstLink holds a 28% stake in Qinghai Province Salt Industry, which owns the mining rights to two salt lakes in China. FirstLink Investments shuttered its Hinode (Singapore) Pte food packaging and distribution subsidiary in 2008.
