plough is not an experienced miner. He is a jounrey man millwright , those figures I gave are just ball park figures I have picked up over the years.
I have some practical knowledge of plant design and have had crushing plants for alluvial operations but I have no underground mining experience.
Would be good to know what actual mining costs are though from some-one who is not an arm-chair miner like I am though.
There are some true UG miners on the MCO thread.
