Okiep Copper Project Continues to Deliver:
20.5m at 4.99% Cu within 43m at 3.41% Cu at Flat Mine South
Results confirm high-grade potential with mineralisation remaining open
- Outstanding assay results received for the first diamond drill holes completed at Flat Mine South:
o Drill hole OFMSD077 intersected 20.50m at 4.99% Cu within 43.00m at 3.41% Cu.
o Mineralisation open for 200m down-dip.
- Flat Mine South, which is a virgin discovery that is blind to surface, will form a key part of Orion's early
production plan for the Okiep Copper Project.
- The intersections achieved to date support geological and grade distribution interpretations that were
incorporated in Mineral Resource modelling and estimation for the Okiep Copper Project.
- Drilling is continuing to test the down-dip extension of high-grade mineralisation in a previously untested
area encompassing 300m of strike and 200m down-dip extent.
- Confirmatory drilling has also commenced at Flat Mine (Nababeep), where an Inferred Mineral
Resource of 1Mt at 1.4% Cu was reported in March 2021.
Orion's Managing Director and CEO, Errol Smart, commented:
"Following our success in confirming the potential for high-grade copper mineralisation at Flat Mine East over the
past month, the first assay results from Flat Mine South, located about 3km to the south-west of Flat Mine East
have delivered further outstanding copper intercepts. These results show that the Flat Mines complex contains
very high-grade copper sulphide mineralisation contained within wider zones of moderate grade intrusive.
"We are encouraged by the potential to rapidly add high-grade tonnes from near-surface bodies such as at Flat
Mine Nababeep, and also down-dip and along trend of the blocks being included in the current mine plan.
"Our initial BFS that is nearing completion has only focused on immediately available JORC compliant Mineral
Resources from FMN, FME and FMS. However, the potential to expand scale and extend the mine life lies at the
core of why Orion invested in the Okiep district. Our aspirational target is to restore our Okiep properties to their
historic production levels of 20,000 - 50,000 tonnes of copper production per annum, which previous owners
maintained for over five decades. Our ongoing drilling results underscore this potential."
Orion Minerals Limited (ASX/JSE: ORN) (Orion or Company) is pleased to report further outstanding assay results
from the confirmation diamond drilling program in the Flat Mines area at its Okiep Copper Project (OCP) in the
Northern Cape, South Africa.
The latest results add further momentum to Orion's development strategy for the OCP, building on the initial
results reported on 22 April 2024 and 24 June 2024 including an intersection of 49.35m @ 5.05% Cu (refer ASX/JSE
release 24 June 2024) at Flat Mine East (FME) among several other high-grade intersections confirming the
geology and endowment of the Flat Mines Area.
The OCP ground holdings of 641km² cover most of the area where a total of 105Mt is reported to have been
mined in the district over the past 100 years (refer ASX/JSE release 21 May 2021). The Flat Mines area and the
current drilling program fall entirely within an executed Mining Right.
Results received and reported in this announcement include the first two of the four planned holes at Flat Mine
South (FMS). The assay results have confirmed historical information from drilling by Newmont and Goldfields of
South Africa (Goldfields) in the 1980's and 1990's, used in the Mineral Resource update, where 9.4Mt at 1.3% Cu
was reported for the Flat Mines including 3.4Mt at 1.4% Cu at FMS (refer ASX/JSE release 28 August 2023).
Flat Mines Confirmatory Drilling Program
A diamond drilling program commenced in the Flat Mines area of the OCP in February 2024. A total of 11
diamond core drill holes were planned at FME, FMS and Flat Mine North (FMN) comprising a total of
approximately 5,800m. This total includes a non-directional deflection for each hole.
The program was designed to confirm historical drilling information and resultant interpretations, provide
geotechnical information and deliver additional material for confirmatory metallurgical test work for the FMN,
FME and FMS blocks included in the initial BFS mine schedule.
The planned program (Figure 2, Table 1) is specifically designed to optimally cover the areas that contribute
most significantly to the overall estimated Indicated Mineral Resource. All holes include a deflection (or wedge)
through the mineralisation to provide the additional material for confirmatory metallurgical test work.

Assay results from the first two holes completed at FMS have been received and are summarised in Table 2 with
results from the complete intersection included in Appendix 1.
Drill hole OFMSD076 returned 6.00m at 0.90% Cu from 454.00m (Table 2). This is all within a broad zone of elevated
copper of 32.32m at 0.63% Cu from 427.68m. Historical hole FMS012, located approximately 20m away from
OFMSD076, intersected 34.80m at 0.74% from 447.90m. Historical hole FMS046, located approximately 20m away
from OFMSD076, intersected 31.82m at 1.14% from 377.18m.
Drill hole OFMSD077 returned an outstanding intercept of 20.50m at 4.99% Cu from 549.50m within 43.00m at
3.41% Cu from 527.00m (Table 2). This is all within a broad zone of elevated copper, but inclusive of wider zones
of internal waste and lower grade, of 62.00m at 2.51% Cu from 508.00m. Historical hole FMS053D1, located
approximately 10m away from ODFMSD077, intersected 38.98m at 2.16% Cu from 574.45m.
Significant widths of waste granitic material are included within the reported intersection widths, providing
opportunities for upgrading of material through modern XRF ore sorting techniques to reject internal waste before
milling. This provides the potential for optimised metal extraction with larger stopes operated at lower mining
cost, while limiting concentrator capital and operating costs.
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 to mine design.
Planned confirmatory metallurgical test work includes XRF sorting, comminution, flotation optimisation and
tailings characterisation. Detailed geotechnical assessment is also undertaken on all intersections.

Flat Mines Exploration and Resource Upgrade Drilling Program
Three of the five drilling rigs have been retained on site to test for an increase in classification of JORC Resource
blocks that are not yet included in the mine plan and to test for extensions of high-grade mineralisation beyond
the margins of the current JORC Resource blocks.
At FMS, historical Goldfields holes and Orion hole OFMSD077 indicate that high-grade mineralisation remains
open down-dip for up to 200m within an untested area encompassing a strike length of 300m (Figure 3).
Historical intersections indicating mineralisation with true widths (TW) remaining open down-dip (Figure 3) include
the following:
• 38.98m (25m TW) at 2.16% Cu including 24.45m (16m TW) at 3.06% Cu in FMS053D1;
• 18.74m (10m TW) at 4.29% Cu including 15.74m (8m TW) at 4.86% Cu in FMS048; and
• 70.96m (34m TW) at 1.21% Cu including 10.24m (5m TW) at 2.81% Cu in FMS047.
Hole OFMSD080 is currently in progress targeting this area, with further holes planned pending interpretation and
assay results.
Figure 3: Long Section of FMS downdip drilling target.
Confirmatory drilling is also underway at Flat Mine Nababeep (FMNb), where an Inferred Mineral Resource of 1Mt
at 1.4% Cu was previously reported (refer ASX/JSE release 29 March 2021). Original drilling over the main zone of
mineralisation was carried out by the Cape Copper Company in the 1940's with 141Kt at 2.72% Cu reported as
being subsequently mined in the 1950's.
Six holes totalling approximately 480m are initially planned to test and confirm the near-surface mineralisation at
FMNb (Figure 4).
Highly mineralised intrusive, similar to that intersected and reporting high grades at FME and FMS, has already
been intersected from 6m to 52m in the first drill hole completed at FMNb (Figure 5). Outcropping exposure and
drill intersections indicate that FMNb is likely to have a high internal waste content. This style of mineralisation is
most suitable for bulk extraction with the application of ore sorting to remove the granitic waste, before milling
the higher grade mafic intrusive rock fraction.
