RE: What Cores and Drilled Mtrs expected 30th April Report ?18 Apr 2020 14:26
@mushroom, very similar to the drilling of glacier samples - the core drill gets a long cylinder of rock out from depth. Unlike in your ice scenario it stays available for scrutiny and doesn't melt! The cores are all stacked in custom boxes, nicely labelled in sequence, and shipped off to the lab for analysis - slicing and dicing, etc etc. The web will show you pretty pictures of all this.
Some one on here mentioned, after gold had been found, exploration had happened, lots of core drilling completed, the mine was built, all the ore shipped off to the smelter.... A third party came in and bought all the old cores from the store room for a few dollars and processed the cores for thousand of dollars profit!
Can't recall the names.....or companies involved, but I was amused at the thought.
