Ring ball closely resembles netball and involves passing the ball from player to player until it is thrown through the goal ring.
The tribal boy, a Class 11 student, from Gumla district - around 130 km west of capital Ranchi - is all of Rs. 50,000 short.
"There's no way my father can arrange such a big amount," Oraon, who has played football and hockey at the regional and national levels, said on Sunday. He has been shuttling between government offices in Ranchi for help.
Oraon and another boy from the state have earned a call up to the national camp and told to be prepared to pay for the travel abroad.
The youngster's village mukhiya (chief), Hari Oraon, has accompanied him to Ranchi. "He is a multi-talented youngster. Besides ringball, football and hockey, he is equally good in volleyball. I will try till the last hour to get a ticket for him to South Africa," the mukhiya said.
