RE: Underground mining - cost?13 Dec 2024 07:50
One thing to remember here is that in the 80s a portal with an incline of a few hundred metres was built underground that goes right to the resource. If it's still usable I don't know. Also in the grand scheme of things mining cost won't be huge and they have plenty of zinc, silver,lead,germanium and gallium that this is ridiculously economical.
