South Africa-focused Orion Minerals on Thursday said that a optimisation work at its Prieska copper project was progressing well, with the company hoping to complete an improved and simple-to-execute project plan by next year.
Key studies currently under way at the Prieska project includes water treatment trials, investigating supplementary means of dealing with the water to be pumped from the underground workings, value engineering of the ore processing plant designs and layouts to improve operational factors and reduce capital and operating costs, and mine-to-market enterprise optimisation of the foundation phase mining plan to assess key market drivers.
