Deposits of cassiterite (tin oxide) are found in other parts of the world apart from Cornwall. This sizeable boulder of water-worn cassiterite was brought to Cornwall from Malaysia in 1910 by Redruth businessman James Wickett.
In 1891 Wickett attended a local lecture on the tin deposits of Malaysia given by a Cornishman who was employed as a mine inspector there. He was quick to spot an investment opportunity and persuaded ten investors in Cornish mines to fund a new mining venture in the under-developed mines of Malaysia. The Gopeng Tin Mining Co. was registered at the Redruth Mining Exchange in 1891, the first of several Cornish-funded Malaysian tin-mining companies. The tin deposits in Malaysia were alluvial, that is contained within river sediments. They required very different mining techniques from those used in Cornwall. Nevertheless, Cornish money, contacts and engineering knowledge were very much in demand in this new tin-mining frontier. In the years to come, cheaply produced tin from Malaysia would contribute significantly to the continuing demise of tin mining in Cornwall.
