I've been doing some research, and it appears that Li can form in greisen type deposits at levels which allow for it to become a saleable by-product. Even though I couldn't confirm source material, the granite in Cornwall (ie. Redmoor) region supposedly has an average concentration of ~300ppm

Cornish Lithium also launched this year. Strongbow has a 25% stake. Targeting hot springs in the Cornwall region.

With all of that said, Li is a buzzword right now. Any indication of Li being present at the Redmoor site should generate favourable news. That's never a bad thing.
