Orion Minerals Limited reported results from its confirmation diamond drilling program in the Flat Mines area at the Okiep Copper Project (OCP) in the Northern Cape, South Africa. The OCP ground holdings of 641km² cover the majority of the area where a total of 105Mt is reported to have been mined in the district over the past 100 years. The Flat Mines area and the current drilling program fall entirely within the executed Mining Right.

Results received to date from the first two completed holes have confirmed historical information from drilling by Goldfields of South Africa (GFSA) in the 1990's, used in the Mineral Resource update where 9.4Mt at 1.3% Cu was reported for the Flat Mines area including 4.4Mt at 1.3% Cu at Flat Mine East (FME). Hole OFMED153 intersected 49.00m at 4.89% Cu, including 10.23m at 12.47% Cu. This intersection is located approximately 13m west of a historical intersection in FME035, drilled by GFSA in 1995, which returned an intercept of 59.10m at 3.55% Cu including 10.12m at 9.83%.

Flat Mines Drilling Program A diamond drilling program commenced in the Flat Mines area of the OCP in February 2024. A total of eleven diamond core drill holes have been planned at FME, Flat Mine South (FMS) and Flat Mine North (FMN) comprising a total of 5,800m. The program has been designed to confirm historical drilling information and resultant interpretations, provide geotechnical information, and provide additional material for confirmatory metallurgical test work.

The planned program comprises five holes at FME, four holes at FMS and two holes at FMN. The holes have been specifically designed to best cover the areas that contribute most significantly to the overall estimated Indicated Mineral Resource. Two holes have been completed at FME, with the remaining three holes currently in progress.

The first two holes are currently in progress at FMS. All holes include a deflection (or wedge) through the mineralisation to provide the additional material for confirmatory metallurgical test work. A total of 149 split core samples were submitted to ALS for analysis by aqua regia ICP-AES method (ALS codes ME- ICP41a and MEOG-46). Drill hole OFMED151 returned 25.22m at 0.97% Cu from 260.00m, including 10.22m at 1.35% Cu from 275.00m.

This is all within a broad zone of elevated copper of 40.22m at 0.80% Cu from 245.00m. Drill hole OFMED153 intersected 49.00m at 4.89% Cu from 231.00m to 280.00m, including 10.23m at 12.47% Cu. One highly mineralised sample of 0.35m length from 280.00m at the bottom of the intersection is pending reporting of assay results.

The OFMED153 intersection compares well to the intersection in historical hole FME035 approximately 13m to the east where 59.10m at 3.55% Cu was reported including 10.12m at 9.83%. The OFMED153 core shows the presence of significant stockwork vein style to massive bornite, and chalcopyrite developed over 11m. Significant widths of waste granitic material are included within the 49.00m intersection in OFMED153, providing opportunities for upgrading of material through modern XRF ore sorting techniques to reject internal waste before milling.

On completion of the drilling program, the geological and mineralisation envelope interpretations will be reviewed and adjusted where necessary, followed by an update of the Mineral Resource estimate including the new information. New geotechnical information will be used for input for mine design. Planned confirmatory metallurgical test work includes comminution, flotation optimisation, locked cycle tests, tailings characterisation and XRF sorting.
