The mining operation will not stop until the profit margin goes away, at which time they will close the doors & move on just like Magcorp did at Knolls.
I'm resigned to the fact that we just have to do the best we can with what is there & don't be surprised by the continuing decline.
All the testing & inspecting I've personally done on the salt was to educate myself, weed out the bull$hit & hopefully enlighten others to the real truth but nothing will change because we all live in a people farming world.
Do the best you can inside your farm & avoid the slaughter house.
