While the abundance of minerals on the moon may be great, considering the cost to mine them and bring them back to earth is sizeable and a profit margin could be very slim ......
OK, the way I see it, is that NASA is just spouting a bunch of BS to justify it's likely outrageously lavish request for funding.
A bag of moon rock brought in $1.8 million dollars at auction:
NASA waged an unsuccessful legal battle to retrieve the bag, which contains traces of lunar dust, from a private collection

Keep in mind, this was completely unrefined material. So, if you were seeking a particular element for commercial use, (say copper to stamp out a penny), you likely wouldn't get the proverbial, "one red cent", out of the whole bag..Even if NASA auctioned off their entire stock, (about 842 lbs.), they would be very lucky if it sold for enough to offset the cost of the mission. (Adjusted for inflation, of course).
Now, we're talking about commercial quantities being brought back, which would have to have approximately the same cost per pound, as material, "mined locally".
Now, earth's gravity being what it is, and the cost of rocket fuel being what it is, a "soft landing" is for all practical purposes, "off the table.
My point being, the only way to get it back to earth with its price being a modest 10 times what it costs on earth, would be to smelt it down on the moon, and "hard land it", back here on earth.
BY "hard land it", I mean as a meteor, accepting the losses you would encounter by material burn off during its reentry. (Actually "entry", since it was never here to begin with).
That said, your trajectory calculations better be spot on, not to mention the cost of its retrieval from somewhere in the northern Canadian wilderness. (And that's assuming Canada would even permit it)..
So, FWIW, I call "Bullsh!t" on this story, and the premise it rode in on.
