RS Mines logoRS Mines (previously GS International & the RS Group), based in Sri Lanka, owns several 99.99% natural high purity crystalline vein graphite mines in Sri Lanka - including their flagship mine, the Queen's Mine.

The company produced graphite oxide (GO) products, offering them via an online store. RS Mines also planned to supply graphene on substrates. In 2016 RS Mines was merged into Global Graphene Technologies and aimed to become a public company in Australia.

The company seems no longer to be in business.
