Strong Results from Maiden Drilling Confirm Outstanding Potential of Okiep Copper Project, South
Africa
Maiden 25-hole program intersects significant copper mineralisation, including 10 holes which
encountered wide zones of high-grade mineralisation
- Successful maiden drilling program completed on the Koperberg – Carolusberg line of intrusives
at the Okiep Copper Project in South Africa, with a total of 25 diamond drill holes completed
totalling 3,411m.
- A total of 14 holes were drilled at Koperberg West, 6 at Koperberg East and 5 at Koperberg West
Extension. The assay results have confirmed historically reported drill results and highlighted the
presence of significant shallow mineralisation.
- 10 holes returned high-grade assay results with best assays including:
- 7.76m at 1.94% Cu from 29.7m including 4.1m at 2.01% Cu from 33.3m in OKED064; and
- 9.02m at 1.45% Cu from 103.08m including 5.9m at 1.86% Cu from 103.08m in OKWED068.
- This is in addition to previously reported high-grade intersections of 10.36m at 1.84% Cu from
58.98m in OKWD100, 5.71m at 1.93% Cu from 72.85m in drill hole OKWD102 and 4.69m at 2.05% Cu
from 49.22m in OKWD105.
- Importantly, the bulk of the Koperberg high-grade intersections are less than 100m below surface.
- Assays confirm that copper-nickel mineralisation was intersected from initial drill testing of a
SkyTEMTM anomaly on the Nous Prospect, with follow-up drilling now underway to test an adjacent,
stronger conductor.
Orion’s Managing Director and CEO, Errol Smart, commented:
“We are delighted with the outcome of our maiden drilling program at Okiep. The results we’ve received
to date have exceeded our expectations, demonstrating the presence of widespread near surface
copper mineralisation across the project and reinforcing what we have always thought – that Okiep
represents an exceptional growth opportunity for Orion.
“The drilling focused initially along the Koperberg - Carolusberg line of intrusives and saw a total of 25 holes
completed, 10 of which intersected high-grade mineralisation. The Carolusberg area was the biggest
contributor to historical production at Okiep and our drilling here has confirmed the tenor and grade of
mineralisation.
“These drill results infill and confirm the previous Newmont and Goldfields era drilling that outline an
extensive, unmined near surface swarm of copper mineralised mafic dykes and lenses. This drilling will now
be followed up with further infill and extension drilling to enable future resource estimation.
“Importantly the mineralisation intersected has strong similarity to the near surface mineralisation mined
along strike at the Carolusberg Mine, which was the largest mine of the district.”
“We are also very pleased with the results from the first hole at Nous that is following upon targets identified
from the SkyTEMTM survey. The higher pyrrhotite content sulphides discovered are nickel rich and present an
exciting new opportunity. With strong market outlook and the LME nickel price currently more than three
times the copper price, a potential nickel credit can be very valuable.”

Orion Minerals Limited (ASX/JSE: ORN) (Orion or Company) is pleased to report highly encouraging results
from its maiden drilling program across the Koperberg – Carolusberg line of intrusions at the Okiep Copper
Project (OCP) in the Northern Cape, South Africa.
All assay results have been received from the Company’s maiden 25 hole diamond drilling program at
Okiep, with the drilling confirming historically reported drill results and establishing the presence of shallow
high-grade copper mineralisation across the project.
In addition, Orion’s first greenfields exploration hole at Okiep intersected veins and massive sulphide lenses
of pyrrhotite–chalcopyrite in drill core within a magnetite rich, mafic intrusive host (refer ASX/JSE release 24
February 2022), with assays confirming the presence of copper mineralisation with significant strong nickel
credits.
This hole tested down-dip of copper mineralisation exposed on surface coincident with an
electromagnetic (EM) anomaly detected by SkyTEMTM and confirmed by a ground EM follow-up survey.
The success of this hole has provided an important proof-of-concept that will assist Orion with ongoing
exploration at the OCP.
Koperberg - Carolusberg Drilling Program
The Phase 1 exploration drilling program on the Koperberg - Carolusberg line of intrusions was designed to
twin, in-fill, and expand - known mineralisation intersected in historical drilling at the Koperberg West,
Koperberg West Extension and Koperberg East deposits (Figures 1 and 2, Appendix 1 Table 3).
The Carolusberg Complex was the biggest contributor to historical mining in the Okiep Copper District,
delivering 38Mt grading at 1.54% Cu out of the reported total of 105Mt mined in the district over the past
100 years (refer ASX/JSE release 21 May 2021). Historical mine records show that Carolusberg Deeps
contributed 16Mt at a head grade of 2.05% Cu (refer ASX/JSE release 3 August 2021).
A total of 3,411m of diamond drilling was completed in 25 holes. A total of 362 split core samples were
submitted to ALS Chemex for analysis and all assay results have now been received.
Drilling confirms the historical drill results and the presence of high-grade, near-surface sulphide copper
mineralisation. Updating of geological models to include the new drill data is currently underway.

Copper mineralisation at the Koperberg West, Koperberg West Extension, and Koperberg East prospects
occurs close to surface (Figures 3 to 7). The mineralisation can potentially be accessible by open pit or
shallow underground mining. Figures 4 and 6 show the modelled mineralisation on level plans.

Nous Prospect
Assay results for drill hole OND001 have been received (Table 2 and Appendix 1 Table 4). The hole tested a
coincident drone magnetic and ground EM anomaly down-dip of surface copper mineralisation occurring in
mafic rocks (refer ASX/JSE release 24 February 2022).
The Nous Prospect (Figure 8) encompasses two adjacent SkyTEMTM anomalies referred to as Target 3 and
Target 4. Both EM anomalies have associated magnetic anomalies. The prospect is located approximately
5km southwest of the historic Nababeep Mine.
Drill hole OND001 at Target 4 intersected 10.00m at 0.67% Cu and 0.07% Ni from 31.70m, including 3.87m at
0.93% Cu and 0.07% Ni from 33.45m (Table 2a). An interpretive cross-section is shown as Figure 9.
Importantly, semi-massive to massive pyrrhotite sampled in the hole assayed up to 0.40% Ni indicating high
nickel tenors in the pyrrhotite (Table 2b) and the potential for strong nickel credits from mineralisation
hosted in pyrrhotite rich copper deposits in the OCP district.

Holes OND002 and OND003 (also at Target 4) intersected granitic gneiss and meta sediments. Massive pyrrhotite
lenses devoid of base metals occurred in meta sediments in hole OND003.
A down-hole EM survey in hole OND001 detected an in-hole conductor where the mineralisation occurs,
confirming EM to be effective in detecting pyrrhotite bearing copper deposits in the OCP.
With Orion having now proved the concept of using EM to detect copper and copper-nickel mineralisation in
the OCP, drilling has started on Target 3 at Nous (Figures 8 and 10), where a relatively strong steeply dipping
conductor has been identified.
The conductor is spatially associated with a zone of intense deformation characterised by steeply dipping F2
fold structures and breccias commonly hosting Cu deposits in the OCP. These characteristic “Steep Structures”
were historically targeted as the most prospective surface indication for blind deposits. Almost all copper
mineralised mafic dykes discovered in the district are hosted in these signature Steep Structures.The target
conductor is substantially bigger and more conductive than the Target 4 conductor.

• Where possible, bulk density measurements were made over the full
length of each individual sample of split core. Where not possible due
to incompetent (crushed or broken) core, a minimum of 80% of the
(half-core) sample was used. The bulk density is determined by
measuring and subtracting the wet weight from the dry weight using
an electronic scale. Care is taken to clean and zero the scale between
each weighing. The intact sample portion is first weighed in air and the
weight recorded. The sample is then weighed, while completely
submerged in clean water within a measuring container. The mass of
container and water are deducted for net submerged weight and
volume displacement read on measuring container. The sample is then
removed and placed back into the core tray in the correct position
and orientation. The procedure is repeated for each geological
sample interval. The data were recorded in the bulk density Data Sheet.
The bulk density is calculated for each sample using the formula:
BD = ____weight of sample_____________________
(weight of sample in air – weight of the sample in water)
