The Moon […] would seem to be an unlikely place to find PGMs: the collisional process that formed from the Moon left it mostly devoid of heavy metals. However, Wingo makes an ingenious case for finding PGMs on or near the lunar surface, in the form of debris from asteroid impacts. While conventional wisdom has argued that impacts of large asteroids would vaporize most of the impactor, modern computer modeling has shown that a significant fraction of an asteroid impacting the Earth would survive in some form. In fact, some major sources of PGMs on Earth, such as Sudbury in Canada and sites in South Africa, have been linked to asteroid impacts. The Moon’s lower gravity would mean slower impacts, making it more likely that significant portions of asteroids could survive. PGMs mined from those impacts could meet the fuel-cell needs of the Earth for centuries; the mining process would, in turn, also generate other metals like iron and nickel that could be used for settlements on the Moon and beyond.

The most detailed study of an asteroid shows that it contains precious metals worth at least $20,000bn.
The data were collected last December by the Near Earth Asteroid Rendezvous (Near) spacecraft which passed close to the asteroid Eros.
It provided an unprecedented look at one of the mountains of rock that fly around the solar system.
The first conclusions from that encounter are now published the journal Science.
Near, which due to a computer malfunction will not be able to go into orbit around Eros until next year, revealed that the asteriod is shaped like a 33 km by 13 km by 13 km banana.
Over a thousand images of Eros were transmitted back to Earth that allowed scientists to estimate its size and mass. The results are startling.
Gold mine in space
Eros is believed to have been formed from the wreckage of a collision with a larger body. Its composition appears to be similar to the stony meteorites that frequently fall to Earth.
That means Eros is a goldmine in space, as well as a platinum mine, a zinc mine and many more minerals besides.
If Eros is typical of stony meteorites, then it contains about 3% metal. With the known abundance's of metals in meteorites, even a very cautious estimate suggests 20,000 million tonnes of aluminium along with similar amounts of gold, platinum and other rarer metals.
In the 2,900 cubic kms of Eros, there is more aluminium, gold, silver, zinc and other base and precious metals than have ever been excavated in history or indeed, could ever be excavated from the upper layers of the Earth's crust
You are digging your own grave. This first one says absolutely nothing about the posibilities to mine either gold or anything similar to it. It only suggest at the faint fraction of a posibility that there are some REEs and even then in the end says this.
I said the articles weren't entirely credible to begin with, but the notion is not as outlandish as you make it out to be. I never intended for those articles to be damning proof of massive amounts of Gold and Platinum, merely evidence that the notion has been considered, isn't entirely feasible, or likely at this point in time, but may be in the FUTURE. The POSSIBILITIES are there. Sure there probably isn't a lot of Gold and Platinum on the Moon, but we can't really say for sure TBH. It comes down to speculation which neither side can prove or disprove. We find new things on Earth every day and we have been here how long? So you are telling me that it is impossible for the Moon to have valuable materials besides the ones you already listed? The truth is we don't know, but you act like we do know. I am not say anything is for certain, but it is fucking possible. I'm not saying we should mine Gold on the Moon, or that it would even be a good idea. If REE were on the Moon that would be a potential spot for conflict in the far future if we really needed them badly.
