LSE-listed Petra Diamonds delivered solid results for the financial year ended June 30, despite a difficult market environment, while it continues its transition from a period of high capital investment to a steady-state operational phase, CE Richard Duffy said on Monday. “The focus in the short term is on driving efficiencies across the business through Project 2022 to provide a stable, consistent operating platform off which to drive improvements, supported by an appropriate organisational structure and cost base to enhance our cash flow generation and significantly reduce our net debt,” he noted.
