A jackpot prize worth R1.364-million was on the brink of expiring if not claimed by Thursday, national lottery operator Gidani said on Tuesday.
Spokesperson Thembi Tulwana said two lucky players' tickets matched the winning numbers last year — 4, 5, 9, 10, 15 and 25 of draw 1093.
Tulwana said one of the winners had not come forward to claim the winnings. This ticket was bought in Randburg.
She said players had 365 days after a winning draw to claim their winnings, and with 2012 being a leap year, the last day to claim was 14 June.
