Castor and Chestnut are not the same thing. Castor is Chestnut plus the rufous modifiers. The deep, rich color of the Castor is only achieved with extra yellow/red pigment from the rufous modifiers; without them, what you have is a Chestnut (an unshowable color in both the Rex and Mini Rex). Unless there are Reds or Castors on the pedigree, you can't be sure that full-color Agouti-patterned babies will be Castors; they may just be Chestnuts. You may not even be sure until the babies are Juniors, since the extra red of the rufous may not show up in the baby coat.

You have not said whether the buck might be carrying REW, Cali or Sable. If he is, there is a possibility of getting Chinchillas and even self patterned Chinchillas. You will need to check the ring color on the Agouti patterned babies as it grows in, and eye color on the selfs - self Chins often have gray eyes. A self Chin will not be as intensely black as a true self Black, though you may have to put them side-by-side to see the difference.

I would argue that it is castor but not showable castor all most all colours are not showable if you start mixing them.

you are correct about the chinchilla I missed that, but they still look like black agoutis to me since they look slightly brown

By this logic, Steel is just a dark Chestnut, or Orange just a poorly colored Red. Anyone who is trying to breed showable Castors will never, ever get there breeding Chestnuts, they need to know the difference.

Steels is caused by the steel gene.
Yes they should know what is showable and isn’t but a pet quality Rex is still called a rex if you take a bad quality castor or as you call it a chestnut and keep the redder ones you can in years get showable castors.
I will not argue with you anymore.

if you take a bad quality castor or as you call it a chestnut and keep the redder ones you can in years get showable castors.

As someone who has bred Mini Rex for more than 30 years, I can assure you, this won't work. Rufous may be considered a modifier, but it is a gene (or rather, a polygene), and if you haven't got the genes to make it happen, it won't. Granted, you might just luck out and buy an animal of another color that just happens to be carrying rufous modifiers hidden under some color that doesn't use them (like maybe Black or Chocolate), and, by selectively breeding its offspring together, arrive at a showable Castor, but unless the modifiers are in there somewhere, you can breed Chestnuts together until the cows come home, and never get to a Castor. Without the rufous, you won't have "redder ones" to breed together, all you'll have is Chestnuts.
