Yes. Is it yours? Do you understand the word "significant"?
Do you understand the concept of "unfulfilled lithium dreams"?

I am so happy about last night that I just cant muster up any invective here, so I will just try to answer amiably.
The Uyuni salt flats are huge. They are equivalent to about 1/3 the state of Oregon in size. They are ringed by several small towns, with the largest being about 30,ooo (Uyuni) and tons of smaller towns and villages. Maybe 250,000 to 300,000 all making a “living” from the salt. They are mostly Quechua Indians, which are a HUGE people group that stretch from N Ecuador down into Chile. (For the record, I used to work with Wycliffe Bible Translators and hung out for a while in Colombia, then hitchiked down to Ecuador and Peru. I have some small acquaintance with them). They are, like any Indian group in S. America, either evangelical Christian or Marxist. They are extremely poor in Bolivia, as that country is a dumpster fire of leftism and drug barons and wealthy elites and poor indians like the Quechua (many Aymara, too). If the fresh water aquifer goes in Uyuni, the people will simply have to move, or die.
The well process in Lithium mining is, like all wells, varied by karst and topography. Most of the karst in Uyuni contains the salt brine, and thus does not need a sleeve to pull up the brine. You are correct in asserting that many wells do have a jacket to avoid spillage into the surrounding sediment, but the theory here is that we are dealing with such high pressure that they just don’t need it. As well, drilling almost never uses deep casing anyway. it is almost always assumed that it is too expensive. Finally, casing is USUALLY not installed until the hole is done and the casing is put in afterwards. I realize this is not always the situation and sometimes the hole is in danger of collapse. In such instances, you case AS you drill. Casing a hole is a pretty advanced subject that requires lots of knowledge about lots of subjects and is beyond our ability to hammer out here. Suffice it to say that the wells in Uyumi have already mixed brine with potable aquifer levels, and the Chinese are noted for being (as any state is) pigs and reckless. There are already plumes of brine seeping into fresh water sources from the drilling, and this is unarguable.
Not everyone who posts about warnings on environmental issues is some pink haired refugee screeching about “global warming” and reciting Chairman Mao. When people post such nonsense, they should expect to get pushback.
