Emerging from a year in which it continued to battle underwhelming diamond recovery, grade and volumes, junior diamond miner Rockwell Diamonds has announced plans to shut its Johannesburg-based head office and embark on retrenchments, informing the market on Thursday that it had already issued its employees with Section 189 notices. The news followed an in-depth strategic and operational review of the business to assess its strategic direction, including its commitment to processing 500 000 m3 a month from its Middle Orange River (MOR) operations, to place the business on a sustainable footing.
