Lepidico Ltd. has reached a significant milestone that demonstrates it can produce catalyst grade caesium compounds. Samples of both caesium sulphate and caesium hydroxide have been generated and are in the process of being dispatched for customer assessment. Further samples of caesium hydroxide are also in the process of being manufactured. Consumers have advised that the caesium market is on the cusp of significant tightening as one of just two size producers of caesium chemicals globally ceases production due to depletion of a major pollucite raw material feed source. Lepidolite is a viable alternative source of caesium when processed using Lepidico's proprietary hydrometallurgical technologies, developed over the past eight years. Conventional roasting of lithium mica concentrates does not generate valuable by-products, with metals such as caesium and rubidium being lost to process waste.
