Weller was first signed by the Suns in 2010 as a 17-year-old as part of the concessions for their list establishment.
Weller has played 28 games in his first two seasons in the AFL, including the last nine games of 2012, and has put pen to paper for another season.
Patrick showed flashes of brilliance through 2012 and with 11 games under his belt, including eight this season.
Hailing from the small Lajamanu community, 900km south of Darwin, Patrick will be with the Suns until at least the end of 2013.
Stanley, who joined the Suns in 2010 via the rookie draft, has been a consistent performer over the past two seasons, culminating in his third placing in the club champion award in 2012 despite missing nine games.
The former Magpie has not only played important roles for the club at both ends of the ground, but has continually improved during his time with the club.
Horsley was a revelation for the Suns in 2012.
Taken with selection two in the rookie draft after several outstanding seasons for Subiaco in the WAFL, Horsley was elevated onto the senior list prior to Round 5 and made his debut that week against North Melbourne.
Horsley played 13 games in his debut season and averaged 17 possessions.
His efforts were recognised at the Suns club champion dinner, with Horsley receiving the Iron Man Award and the Most Professional Award.
Suns football operations manager Marcus Ashcroft said the quartet represented an important part of the club's future.
He was delighted to have them all re-signed prior to the club's departure to Arizona for a high altitude training camp.
"A number of our players are displaying real commitment to the club, and that in turn gives us great confidence that the players believe in our program and are determined to deliver success for the Gold Coast Football Club and our fans," Ashcroft said.
"Maverick has been with us since he was 17, and we look forward to seeing his continuing development.
"Liam Patrick is a great story. Coming from such a remote part of Australia and carving out an AFL career is something he should be very proud of.
"Danny Stanley has also been with us since our first game in the VFL, and showed his value to our side this year, reflected by his third placing in the best and fairest award.
"Kyal Horsley's perseverance to make it to the AFL has been outstanding and his professionalism since joining the Gold Coast Suns has been exemplary."
