Multiple copper sulphide intercepts within large VMS system at Boksputs opens up exciting new
discovery opportunity
Deep diamond drill hole still in progress intersects numerous mineralised zones across multiple horizons at
southern end of a 3km long mineralised system 125km north-west of the Prieska Copper-Zinc Project
- Significant zones of copper, zinc and nickel-copper-PGE mineralisation intersected across all key
prospects tested as part of the high-impact near-mine and regional drilling program across
Orion’s tenement holdings in the Northern Cape Province, South Africa.
- Results confirm the under-explored nature of the Areachap Province and the substantial
opportunity for a major discovery, both in the near-mine environment around the fully-permitted
Prieska Copper-Zinc Project, and the broader region.
- A key focus will be the greenfields Boksputs Project, located 125km north-west of Prieska, where
a deep diamond drill hole has intersected numerous zones of VMS copper mineralisation across
multiple horizons, with initial assays including 5m at 1.09% Cu and 0.13g/t Au from 393.00m and
1m at 2.25% Cu and 0.32g/t Au from 498.45m.
- The hole is still in progress to test an electro-magnetic (EM) conductor within a large VMS
mineralised package with multiple historical intercepts, EM anomalies, outcropping exhalites and
mineralisation over an area extending over 3km by 1km.
- Intensive follow-up drilling is planned, including to target a strong 3000 Siemens conductor
located 3km north of the current drill hole (compared with the current 400S conductor).
- Drilling at the Kielder Project, located 15km from Prieska, has intersected high-grade base metal
mineralisation close to surface, successfully validating historically reported copper and zinc
sulphide mineralisation across two VMS prospects.
- Plus, at the Jacomynspan nickel-copper deposit, 68km north-west of Prieska, drilling has
intersected three shallow zones of net textured sulphides with a best intercept of 6.03m at 0.60%
Ni, 0.31% Cu, 0.19g/t Pd, 0.21g/t Pt and 0.20g/t Au from 145.36m, including 1.10m at 1.23% Ni and
0.69% Cu from 146.35m.
Orion’s Managing Director and CEO, Errol Smart, commented:
“We could not have asked for a better start to 2021. Against the backdrop of soaring base metal prices and a
fantastic outlook for copper, zinc and nickel amidst a stimulus-fuelled global economic recovery, we have been
able to deliver some very exciting exploration news from the pre-Christmas drilling across our extensive Areachap
tenement holdings in the Northern Cape.
“The strategic significance of all these targets is that they form part of a world-class exploration package that is
underpinned by our fully-permitted Prieska Copper-Zinc Project – which remains one of the few advanced base
metal assets worldwide ready to move into construction this year. Some of the targets are ‘near-mine’
opportunities that could quickly develop into satellite ore sources for the Prieska mill. Others sit further afield and
have demonstrated strong geological potential to emerge as potential major new VMS discoveries of a similar
size to Prieska, or perhaps even bigger.”

“The project that has really caught our attention is Boksputs, which fits the latter category. It was originally drilled
by Anglo American back in 1973 and yielded some promising copper intercepts, despite patchy information
being available. We know that it sits within a large syncline, has outcropping mineralisation, historical intercepts
and EM anomalies over a massive area of 3km by 1km, and exhibits all the lithologies and characteristics of a
very large VMS system.
“Our first diamond drill hole, targeting a 400 Siemens EM conductor at one end of the syncline, has intersected
multiple zones of copper-bearing sulphide mineralisation associated with chloritization and magnetite. The hole
is still in progress, but the evidence we are seeing from the drill core is that we are in a very big VMS system –
which really excites us.
“Based on the encouraging results so far, we intend to substantially accelerate exploration at Boksputs, including
a further deep diamond drill hole to test a strong 3000S EM conductor 3km to the north at the other end of the
syncline, along with surface EM and RC drilling across the entire strike length of the structure.
“Elsewhere, drilling at the Kielder Project, located just 15km from Prieska, intersected shallow high-grade base
metal mineralisation, validating historical results and elevating this as a priority near-mine opportunity. Meanwhile
at Jacomynspan, 68km to the north-west, we have intersected multiple zones of shallow higher grade Ni-Cu-Co-
PGE-Au mineralisation that may have importance for open pit mining potential and secured samples for
metallurgical test work. This is another promising growth opportunity for the Company.
“We expect the next six months to be a transformational period for Orion as we step-up exploration and secure
the financing to start construction at Prieska. This is a project whose time has well and truly come, and we are
excited about the opportunity to finally bring it to fruition, for the benefit of our shareholders and the communities
in the Northern Cape region. We see this district being a long-term source of high-quality base metal
concentrates that will help to support the ‘new era’ of global economic growth which is widely expected to
unfold this decade.”
Orion Minerals Limited (ASX/JSE: ORN) (Orion or the Company) is pleased to report highly encouraging results
from high-impact exploration drilling programs targeting near-mine and regional volcanogenic massive sulphide
(VMS) copper-zinc and nickel-copper targets around its flagship Prieska Copper-Zinc Project (Prieska Project) in
South Africa’s Northern Cape.
Drilling was undertaken during the December 2020 Quarter on the Prieska Copper-Zinc Mine (PCZM), Namaqua-
Disawell and Masiqhame prospecting rights, including the K3 and K6 prospects at the Kielder Project within the
Dooniespan Prospecting Right, the Jacomynspan and Area 4 prospects within the Namaqua-Disawell
Prospecting Right, the B4 anomaly on the Boksputs Prospect and at the Kantienpan Prospect on the Masiqhame
Prospecting Right (Figure 1).
Base metal sulphides were intersected at all five prospects drilled, with the drilling program delivering highly
encouraging early results despite being impacted by restrictions associated with the COVID-19 pandemic, a
reduction in field staff, slower sampling and assay turnaround and the lack of availability of down-hole
geophysical instruments that are currently stranded in Australia due to logistical challenges.
Despite these temporary challenges, Orion intends to substantially expand its exploration activities within the
Areachap Province in the coming weeks given the very promising results generated so far and the potential to
unlock major new growth opportunities for the Company.

Boksputs Prospect – Masiqhame
Potential for a large-scale greenfields VMS discovery
The Boksputs copper prospect is located close to the northern boundary of the Masiqhame prospecting right,
some 125km NNW of the Prieska Project (Figure 1).
Copper mineralisation was discovered by Anglo American Corporation in 1973 following an airborne electro-
magnetic (EM) survey, ground geophysics and soil geochemistry. The prospect was tested with 12 shallow
diamond drill holes.
The B4 EM anomaly was detected by Orion using fixed loop time domain electromagnetic (FLTDEM) follow-up of
previously generated SkyTEMTM anomalies at Boksputs. Modelling of the data revealed a 300m x 1,000m plate
with a conductance of 400 Siemens (refer ASX release 20 October 2020). The plate fits the geology with the B4
conductor developed in the Kraalkop Synform, located stratigraphically below the historical VMS intersections
reported in the Anglo American drill holes (Figures 2 and 3).

Boksputs, Northwest Cape, South Africa – a possible Besshi Type deposit. Mineral Deposita 22, pp. 81 – 89 (1987).
Diamond drill hole OBPD001, which was collared to test the B4 EM plate, is still in progress and has so far
intersected numerous zones of copper-bearing sulphide mineralisation associated with chloritization and
magnetite. Mineralisation has been intersected in multiple horizons and occurs as remobilised sulphide stringers
and disseminated sulphides as well as stratabound primary, massive pyrrhotite-pyrite-chalcopyrite layers with
both remobilised and primary sulphides (Figure 4 below).
Significant assay results received to date are set out in Table 1 below:

Table 1: Intersection table for hole OBPD001.
Figure 4: Photo showing a zone of flexure slip with disseminated pyrite and chalcopyrite intersected in OBPD001 at 448.82m. This suggests that
remobilisation of sulphides happened during the late folding phase.
Detailed logging of the drill core by experienced members of the Orion exploration team indicates that the hole
has intersected strong zones of alteration and signature VMS lithologies similar to those seen at the Prieska Project,
confirming Boskputs as a large-scale, high-priority target area for base metal VMS mineralisation.
The mineralised package – with multiple historical intersections and EM anomalies – covers an area of roughly
3km x 1km, with outcropping mineralisation and drill intersections occurring to 550m depth.
Hole OBPD001 is currently being deepened, but assay results from the first four zones of mineralisation provide
strong encouragement for follow up down-hole electromagnetic (DHEM) surveys and drilling.
The results obtained in OBPD001 also upgrade the exploration potential of the conductors detected on the B1
and B2 anomalies, located 3km to the north of B4 (Figure 2). At B2 the conductance of the modelled plate is up
to 3000 Siemens compared to the 400S conductor at B4, suggesting the presence of more coherent and massive
mineralisation in the same stratigraphic horizon.
A comprehensive exploration program including moving-loop ground EM and both shallow and deeper drilling
is currently being planned.
Kielder Project – PCZM Near Mine
Newmont South Africa (Newmont) discovered VMS-style copper-zinc mineralisation at three prospects on the
Kielder Project, located 15km from Prieska (Figure 1), in 1976. The shallow depth of the mineralisation offers a
significant opportunity for Orion to delineate a shallow, near-mine deposit with the potential to deliver
supplemental tonnage for an expanded operation at Prieska.
Six prospects were identified by Newmont with available reports indicating that the K3 and K6 prospects had
returned the best results (refer ASX release 20 October 2020).
Drilling at Kielder was designed to verify the historically reported results in historical drill holes KDH3 and KDH15, as
well as to provide a platform for modern high-powered DHEM surveys.
Drill holes OKD031 and OKD032 intersected VMS mineralisation and verified the historically reported drill results,
with hole details and assay results summarised in Tables 2 and 3 below:

OKD031 was drilled 10m down-dip from KDH3 and intersected 9.39m at 0.14% Cu, 3.41% Zn and 0.14g/t Au from
174.73m, including 4.81m at 0.14% Cu and 4.49% Zn from 189.16m (Table 3).
OKD032, drilled 25m from KDH3, intersected 3.9m at 0.30% Cu, 7.87% Zn, 10g/t Ag and 0.16g/t Au from 123.2m
and 2.21m at 0.70% Cu, 1.70% Zn, 36g/t Ag and 0.20g/t Au from 129.94m.
OKD033 was drilled 10m from historical hole KDH2 and showed potential high variability in the mineralisation at
K3.
The copper and zinc sulphides intersected are shown in the photograph in Figure 5 below and the location of
the historical and recently completed holes is shown in Figures 6 - 9.

Figure 9: Cross-section through drill holes KDH15 and OKD032 showing the sulphides intersected in drill hole OKD032.
Despite intersecting high-grade massive sulphide mineralisation at K6, Newmont geologists reported that the
geophysical techniques available in the 1970s, including electro-magnetic (EM) surveys, failed to detect the
mineralisation. This rendered geophysical targeting for down-dip and along strike extensions virtually impossible
at the time.
This technical challenge contributed to Newmont declining to exercise the option they had to acquire the
mineral rights, and exploration on the prospect ceased for nearly 50 years until Orion’s recent work.
Orion intends conducting orientation geophysical surveys at K6 using modern geophysical techniques and, if
successful, applying these techniques to trace the extensions of K6 and other weaker SkyTEM TM anomalies like
K5 and covering the VMS target horizon. DHEM surveys are planned for holes OKD031, 032 and 033 as soon as
geophysical instruments currently in Australia can be secured.
The Company’s exploration team believes that there is significant potential for a combined approach utilising
structural analysis together with high-powered, modern surface and down-hole geophysics as a viable targeting
method for the mineralisation, which has demonstrated significant near-surface copper and zinc grades.
Kantienpan Project - Masiqhame
Iscor started drilling on the Kantienpan prospect in 1998. Iscor used an internal laboratory and there are no QA-
QC reports available for the 13 diamond drill holes. Quarter core samples from four holes were sent to GoldLab
Africa for check-assay (refer ASX release 20 October 2020). GoldLab Africa reported higher zinc grades in all four
holes. Should the zinc grades be substantially higher, as indicated by the GoldLab Africa analysis, it may justify
progressing to a resource drill-out of the deposit.
Orion selected four holes for twinning (Figure 10). The holes are listed in Table 4. Hole OKND019 twinned hole
KD005 and was completed in December 2020 (Figure 11). OKND019 intersected 7.5m at 0.49% Cu, 7.22% Zn and
0.1g/t Au from 81.00m (Figures 11 and 12). Comparison with the Iscor hole KN005 is given in Table 5.
Meaningful conclusion on comparison of the results can only be done after completion of all four twin holes.

Area 4 Prospect – Namaqua – Disawell Project
Between 1975 and 1983 Anglo American carried out limited exploration at the Area 4 prospect. Two diamond
drill holes were drilled, targeting geochemical, magnetic and IP features. Both holes intersected mafic-ultramafic
intrusive rocks. Drill hole JAC007 intersected a broad sulphide zone of 62.5m grading 0.26% Ni and 0.17% Cu from
270.30m (refer ASX release 3 July 2018). Drilling targeted geochemical, magnetic and IP targets.
Orion carried out FLTDEM surveys over Area 4 using two grids, A4A and A4B. Seven plate models of conductance
ranging from 350 – 2000 S, with smaller dimensions characteristic of semi-massive to massive sulphide
mineralisation within or on margins of disseminated sulphide mineralisation, have been modelled (Figure 13).
Drill hole OA4D001, completed in November 2020, intersected two zones of mafic-ultramafic rocks separated by
61.70m of metapelitic rocks. The upper zone of 60.90m intersected from 17.00m down-hole consists of pyroxenite
that hosts two layers of harzburgite from 21.64m to 23.62m and from 50.47m to 54.45m.
This unit is mineralised with disseminated pyrrhotite and contains nickel and copper concentrations up to 0.28%
Ni and 0.15% Cu over 5m from 70m down-hole (Figure 14, Table 6). The lower unit was intersected over 33.92m
from 143.30m down-hole and consists of non-conductive gabbro-norite devoid of sulphides. The modelled EM
plates with strong conductance are therefore not explained by the drilling intersection.
A down-hole EM survey is planned to detect off-hole EM conductors and assist with modelling of the ground EM
data.

Jacomynspan
Drill hole OJPD054 was completed to test the potential of shallow Ni-Cu-Co-PGE- Au mineralisation on the
Jacomynspan nickel-copper prospect. Jacomynspan hosts a Mineral Resource of 6.8Mt at 0.57% Ni, 0.33% Cu,
0.03% Co, 0.19g/t Pt, 0.12g/t Pd, 0.07g/t Au2 (Figure 15) (refer ASX release 20 October 2020).
The deposit has been extensively drilled over the 3km strike length of the intrusive to a depth of 900m; however,
the upper 150m of the outcropping deposit that is oxidised to depths of 30m - 60m, remains largely untested and
presents an attractive open pit mining prospect.
Historical hole JMP030 intersected higher grade mineralisation of 0.40% Ni and 0.29% Cu over 29.14m at a vertical
depth of 120.86m hosted in harzburgite on the hanging wall contact of the ultramafic intrusion (refer ASX release
8 March 2018). OJPD054 was drilled to test for the up-dip continuation of the Harzburgite 25m up-dip of JMP 030
intersection (Table 7).
The hole revealed that the targeted harzburgite does not continue up-dip, however several additional
unexpected hartzburgite horizons with higher grade sulphide mineralisation were intersected in the stratigraphic
footwall of the target (Table 7, Figure 16). These results show a more complex distribution of mineralisation than
previously modelled, including numerous shallow higher grade zones that have merit to evaluate for future
selective open pit mining.
Close-spaced, shallow drilling is being planned to test and map out these shallow lenses of mineralisation with
attractive Ni-Cu-PGE-Au mineralisation and to collect samples for metallurgical test work.
