Orion Minerals (ASX:ORN) said the release of the definitive feasibility study for the Flat Mines copper project in South Africa was delayed to the last week of March, according to a Friday Australian bourse filing.
The board and partners are currently working on an internal review following a sign off by the independent experts.
It is expected that the results of the Okiep definitive feasibility study will be released concurrently with the release of Orion's flagship Prieska copper-zinc mine definitive feasibility study.
