Thanks for the heads up. I skipped the video and just googled the project, it actually sounds pretty cool. 1.6km deep bore with all of the head works hidden ~45m below ground, you can't see any of the mine beyond a farm building from nearby on the surface. There's a 37km conveyor system for moving the mined product to the shore to load on ships too, the whole project is massive. Their main product is mineral fertilizer for organic farming too, which is awesome.

I hope The B1M does a video about this mine, then it's not just a Reader's Digest style article read over stock footage :)
