Total capital investment of $3.6m for the development of these two mines was internally funded.

According to Rockwell, the objective of the strategy is to improve quarterly earnings through the increased recovery of large, high value diamonds.

As part of the strategy, Rockwell has also commissioned and operated the more efficient Bulk X-ray technology in concentration and recovery mode in order to eliminate the need for lesser efficient and more costly pans or DMS technology.

Rockwell CEO and president James Campbell said that the company has recently delivered on several notable milestones towards our medium term core business strategy to increase alluvial production volumes in the Middle Orange River region to 500,000m3 per month.

"These will bring our average monthly production volumes on the Middle Orange to 360,000m3, putting us on track towards our medium term target and also leading to improved quarterly earnings," Campbell added.

"Our investments to grow Middle Orange production also have socio-economic benefits for this region which is impacted by high unemployment," he noted.
