Our recording of July’s excellent webinar with Professor David James explaining the economics, geology and (lack of) science behind the scattering of mines optimistically built in the Cambrians over the ages, is available above.  And, if viewing (or remembering) it leaves you wanting more then we’re pleased to say the Cambrian Mines Trust has agreed to run a CMS Members’ tour of the Cwmystwyth mines site which they manage, in summer 2024.
