BRB has silver spots on his back?

Well if it wipes off, then its probably mite poop as I think I read somewhere that snake mite poop is silver. If it doesn't wipe off like you said, then I would definitely watch it and if it doesn't grow or get worse, then I probably wouldn't worry about it, chalk it up as a "birthmark" on him.

He is finally being treated for the mites. I tried wiping it off but I dont think any came off.

Mites are finally gone and he is about to shed. Hopefully they will be gone after the shed!

Mite treatment needs to last for 8 weeks as it can take 30 days for an egg to hatch.

Really?? I was told 3-4 weeks. Ill keep the treatment going.

He just shed today and some of the spots are still there. What could they be?
