Orion Minerals Drilling Hits More High-Grade Copper In South Africa

Orion Minerals Ltd (ASX:ORN) has revealed further outstanding drilling results from the Flat Mines Area at its Okiep Copper Project (OCP) in South Africa.

Highlight results include:

  • 9.27m at 3.01% Cu (copper) and 15.00m at 4.80% Cu within 78.00m at 1.57% Cu; and
  • 50.00m at 1.09% Cu including 18m at 1.44% Cu within 116.9m at 0.75% Cu.

The latest results add further momentum to Orion’s development strategy for the OCP, building on the initial results reported in April and confirming the geology and endowment of the Flat Mines Area.


The OCP ground holdings of 641 square kilometres covers the majority of the area where a total of 105 million tonnes have been mined in the district over the past 100 years.

A diamond drilling program started in the Flat Mines Area of the OCP in February 2024.

A total of 11 diamond core drill holes are planned at Flat Mine East, Flat Mine South and Flat Mine North comprising a total of ~5,800m.

The program was designed to confirm historical drilling information and resultant interpretations, provide geotechnical information and deliver additional material for confirmatory metallurgical test work.

Results amplify potential

Orion Managing Director and CEO Errol Smart said: “These drilling results further amplify the potential for the Flat Mines orebodies to replicate the typical nature of Okiep copper intrusive mineralisation, where zones of very high-grade mineralisation are commonly contained within large bodies of moderate grade.

“This clearly shows why this district has been such a prolific producer of copper for such a long period of time.”

Potential metal supply deficit

Smart said the company has been frustrated by the slow turnaround from accredited laboratories, which are overloaded with exploration samples.

He noted that this is indicative of the intensity of activity in the copper exploration industry and is in itself an indicator of the challenges involved in accelerating mine development to counter the global metal supply deficit that is developing.

BFS nearing completion

“We are pleased to be nearing completion of our Bankable Feasibility Studies so that we can progress to project finance and mine development on our brownfields redevelopment sites, in parallel with ongoing drilling and exploration to expand our resource base on our surrounding highly prospective mineral rights,” added Smart.
