Brooks has already spent a season as a professional with the magpies, having signed his first professional contract ahead the 2019/2020 campaign.
However, Palmer has reached a milestone moment after securing his first professional deal.
Via the official Notts County site, Head coach Ian Burchnall said: “While he’s still got a lot of work to do,
"Tiernan’s a very good goalkeeper who’s shown progression, hunger and a good attitude month-on-month. He’ll take a lot from people like Sam Slocombe and Jake Kean and hopefully we’ll continue to see him progressing this season.
“Tyreace has been at the football club for a long time now
"We’re pleased to give him the platform to express himself. While he’s also got a lot of development to come, I think he’s got potential as a goal scorer and being around our squad on a daily basis is only going to help him."
