Not actual drops of water, or even molecules of H20, but its ingredients, atoms of hydrogen and oxygen embedded in the crystal structure of the mineral itself. This hydrous mineral isn’t wet. But when it melts, out spills water. The discovery was the first direct proof that water-rich minerals exist this deep, between 410 and 660 kilometers down, in a region called the transition zone, sandwiched between the upper and lower mantles.
Since then, scientists have found more tantalizing evidence of water. In March, a team announced that they had discovered diamonds from Earth’s mantle that have actual water encased inside. Seismic data has also mapped water-friendly minerals across a large portion of Earth’s interior. Some scientists now argue that a huge reservoir of water could be lurking far beneath our feet. If we consider all of the planet’s surface water as one ocean, and there turn out to be even a few oceans underground, it would change how scientists think of Earth’s interior. But it also raises another question: Where could it have all come from?
... So all the water was delivered by comets or asteroids after the formation.
If that’s the case, at least some of Earth’s interior water must have always been here. Despite the heat in the early solar system, water molecules could have stuck to the dust particles that coalesced to form Earth, according to some theories.
Induced fission Very much like neutrons do in nuclear reactors, neutrinos can induce fission reactions within heavy nuclei. So far, this reaction has not been measured in a laboratory, but is predicted to happen within stars and supernovae. The process affects the abundance of isotopes seen in the universe. Neutrino fission of deuterium nuclei has been observed in the Sudbury Neutrino Observatory, which uses a heavy water detector.

the depth of the well in Antarctica is 3,679.15 meters, the depth of the Kola borehole is 12262 meters, and the temperature is 220 ° C. The depth of the wells made by the USA in Hawaii is 3000 meters.it is a lie that is impudent to assert that there are at a depth of 200+ kilometers

Maybe we should worry less about deep space objects that would and probably will be impossible to ever reach and worry more about what’s already HERE(oceans, deep Earth). I don’t think there’s anything to gain from things like the Crab Nebula, other than cool “pictures”. I suppose the same type of funding scams go for space exploration as archeology, maybe not. Why worry about such a desolate, unlivable place like Mars when all the REALLY cool undiscovered stuff is right here? And we KNOW it’s here, yet we spend tons of money on a “we’ll see” project. I agree that the pictures that Voyager and all the other space probes are VERY cool, but it’s just not realistic IMO to do much more than that with all the GUARANTEED discoveries we will find on Earth. Maybe it’s just me, but it seems flying around visiting other planets, with all the problems here(and the problems with flying around visiting planets like the Twilight Zone) seems very unlikely.
They do not claim a bore hole at that depth or any other and since the Earth's radius is over 6,300Km then a depth of +220 is not a lie nor impudent. The mineral in the OP was theorized to be at that depth, due to its crystalline structure, and then ejected to the surface by volcanic activity.

This reminds me of the samples brought back from the comet Wild2 by the Stardust mission. The line between comet and asteroid has been blurred by the evidence found from that mission. Could comets have the same type of mineral that release water through ionization?
Most of these were likely not comets but rather asteroids called carbonaceous chondrites, which can be up to 20 percent water by weight, storing it in a form of hydrogen like ringwoodite.
