@michaelharrison3046 BTW--I come as 3rd gen mining background, more informed but biased in favor of extractive industries done right
There won't be an open pit or anything spectacular changed about that valley. Nothing much cleaner than simply pumping an extremely salty shallow aquifer that could never be used for anything else, evaporating the water in the sun and wind and extracting a couple components. It's mostly solar powered with incredible efficiency. :D
Those salts are from recurring lakes without outlets, filled and evaporated by climate changes for M's of yrs, massive glacial till/runoff, made lakes far bigger than the Great Lakes at times in recent past Nevada.
As glaciers advance and retreat, repeat, fresh water (always some natural salts in fresh) gradually becomes far saltier than the oceans. Lake may be Yuge but shrinks to the lowest points, again, concentrating the salts. The geology retains the brine indefinitely.
I assume they are dropping the small valley floor a little via the removed brine and the surface will have more salts than it used to...pending the next time ice sheets again level the N. Hemisphere, most recent only ended around 14k yrs ago, yesterday in geologic terms and well within human experience...tangent.
Otherwise it will be more or less the "wasteland" it always was.
Pardon caring on, sheesh.

@staralioflundnv At 1st blush I would think seismic activity, even severe quakes, would have negligible effect on zone beyond plug due to above stated reason....given distance underground.
It would of course be of concern for the surface infrastructure. I'd want everything possible to be underground where it's safe, turbine, electrical, etc. Also having everything at constant temperature and protected from snow drifts, freezing and so on.
Rocks come off the cliffs like bullets and pass right thru any manmade object, vehicles, structures or whatever, even with common modest 7 mag quakes. Dad would order everyone to stay underground until aftershocks dissipated.
Funny tangent story but relevant: Easy Go is about 3 miles plus long (called Easy Going because prior to that tunnel they had to transport all the 100s of employees up treacherous switchbacks on steep avalanche prone roads to around 10k alt original access and offices)
Ray Gray (dad) designed the tunnel and the ditch on the side of it, for most of the length of the long tunnel mining process "Gray's ditch" was a standing joke bc it was dry until near the end when hitting abundant water and it filled to the top.
This was not trivial bc the entire tunnel must be bigger and more expensive to accommodate the ditch. Dad simply measured the flow from many existing tunnels per length and averaged the results to figure the flow rate needed and it turned out to be on the money, pun intended. Some luck no doubt but everyone forgot the Gray's Ditch joke after that.
SO...that plug could have been installed deep under and still capture most of the water available. In some places the water would blast out against the train cars as you passed, it was like Disneyland but better.
