Speaking following the four-day festival Kevin Paterson, Maxol Group's commercial manager said: "We were delighted to welcome so many young rugby players to have the opportunity to take part in this festival at such a wonderful stadium.
"Maxol's sponsorship with Ulster Mini Rugby really demonstrates our commitment to grassroots rugby and to serving the local communities."
Maxol is the title sponsor of the Ulster Mini Rugby Programme and as well as the Primary Schools Festival, club grounds across the Province host similar events over the course of the season.
The Maxol Mini Rugby festivals attract thousands of young players, offering them the opportunity to develop their rugby skills and meet their Ulster Rugby heroes.
Mini Rugby is the introductory level of the sport throughout Ulster, in which boys and girls aged 6-12 gain their first taste of the sport and begin to learn the basic skills.
