The note on DX-World doesn't (or no longer) appears on QRZ.com. It was updated at 2038 with general info and the dates of operation. So apparently it is now licensed?
Checked QRZ today and here's the message on their page:
"This will be the QRZ page for the SARL Nelson Mandela Commemoration Station.
Please note that no licence has yet been issued for operations to begin - hence no QSLs will be exchanged with any station for QSOs that take place prior to confirmation by the SARL that a licence has been issued under this callsign.
You will know whether you have contacted the official SARL station by checking the operating schedule that we will publish here.
Watch for updates here!

I hope my (and others) QSO is valid. I still have my doubts. I hope I'm wrong.
