The 22-year-old has been solid on the Challenge Tour this season and currently ranks 14th in the Race to Oman, despite missing the cut in his last two starts.
Fond memories of Penati Golf Resort could spark a turnaround for Stone, who shot rounds of 68, 69 over the weekend there last year, eventually taking sole 10th on 13-under-par.
This season he showed signs of promise, beginning the year with a playoff second place at the Barclays Kenya Open.
Last month at the Najeti Open he tied for eighth place, finishing that week in France on two-under-par at the tough Saint-Omer Golf Club.
From Thursday his attention will be on Slovakia, where he will be joined by countrymen Haydn Porteous, Zander Lombard, and Dylan Frittelli.
Porteous, who was the Sunshine Tour’s 2014 Rookie of the Year, won the Barclays Kenya Open earlier this season. He has placed in the top 20 at his last three starts on the Challenge Tour and currently ranks eighth in the Race to Oman, making him a favourite for this week.
Lombard, on the other hand, is aiming to gather experience on Europe’s feeder tour and will make use of a tournament invitation in the hopes of producing the top-10 result that has eluded him all season.
