Prieska project development
In September the company completed the major component of its Black Economic Empowerment (BEE) restructure, marking another important step forward for the Prieska Copper-Zinc Project in South Africa.
The transactions included the issue of Orion shares to key existing BEE shareholders at the asset level and a simultaneous transaction with new BEE partner company Prieska Resources Pty Ltd.
Managing director and CEO Errol Smart said at the time: “We are pleased to have completed the major component of our BEE restructuring.
“This comes hard on the heels of the grant of a mining right and shows that we are continuing to tick all of the key boxes required to move the Prieska project forward as rapidly as possible.”
The effect of the transactions is to implement an ownership structure whereby Orion holds a 70% interest in Repli Trading No 27 Pty Ltd, which owns the majority of the Prieska project.
