The exact timing and process for the next diamond parcel export to Petra's marketing office in Antwerp and subsequent sale will now be finalised between the Company and GoURT.

A resolution has not yet been reached with regards to the parcel of 71,654.45 carats from Williamson that was blocked for export (as announced by Petra on 11 September 2017). The Company will provide an update on this as soon as practicable.
