Orion Minerals (ASX: ORN) reported a new diamond drill hole from Flat Mine East at its Okiep Copper Project in South Africa's Northern Cape. Hole OFMED158 returned 3.96m at 4.64% copper from 322.69m down-hole, including 0.95m at 14.19% copper, according to the company's exploration update.
The intercept extends mineralisation 39m down-dip from an earlier hole, OFMED157, which hit 7.88m at 9.24% copper, including 3.33m at 17.12% copper. The new result confirms a high-grade, norite-hosted copper zone continues at depth and remains open, Orion said.
The company also noted that OFMED158 has not yet been incorporated into the mineralisation model. Any near-term shift in resource shape, grade or tonnage depends on further drilling and updated modelling.
Flat Mine East sits within the Okiep Copper Project, a 703-square-kilometre district in the Northern Cape. Orion is advancing the Flat Mines area as a defined development zone. The March 2025 Mineral Resource for Flat Mines stood at 10.0Mt at 1.3% Cu under JORC 2012, using a 0.7% copper cut-off. The FY2025 annual report described Okiep Flat Mines as a lower-capital starter project, with a 12-year life-of-mine outlined in the 2025 DFS. Optimisation work is under way.
