Shallow Massive Sulphide Intersections at Two Near-Mine Prospects at the Prieska Copper-Zinc Project
Initial diamond drilling underway at exciting Kielder VMS prospect, just 15km from mine infrastructure
Drilling at the Kielder Project located 15km from the planned mill at the proposed Prieska Copper-
Zinc Mine in the Northern Cape, South Africa intersects massive copper and zinc sulphide
mineralisation.
Intersections are near surface.
Drilling tested outcropping VMS-style mineralisation with results of up to 4.8m @ 0.46% Cu, 6.18% Zn
and 15g/t Ag from historical shallow drilling by Newmont SA in the 1970s.
Rigs now moved to test targets at the Jacomynspan Ni-Cu-Co-PGE Prospect on Orion’s Areachap
prospecting rights, where it will test for shallow high-grade nickel-copper mineralisation and
provide samples for metallurgical test work.
Orion’s Managing Director and CEO, Errol Smart, commented:
“This is an exciting start to our recently commenced high-impact exploration program at Prieska. We have
intersected shallow, base metal massive sulphide at two different prospects in our very first holes at the near-mine
Kielder Project. This is a clear demonstration of the enormous exploration upside around the proposed Prieska
Copper-Zinc mill which offer opportunities to extend the mine life and grow our production profile in the future.
“Based on visual observations, the intersections we have drilled are geologically very similar to what we see at
the main Prieska copper zinc deposit and, excitingly, they occur at very shallow depths which bodes well for their
future economic potential.
"The planned Prieska Copper-Zinc Mine is one of the few fully permitted and development-ready base metal
assets worldwide, underpinned by a compelling investment case outlined in the updated BFS of May 2020 which
included an NPV (at an 8% discount rate) of AUD779 million from a 12-year foundation phase mine, planned to
produce ~22ktpa of copper and ~70ktpa of zinc1. Exploration success in the near-mine environment will build on
these strong fundamentals, unlocking the potential of what we believe to be a significantly under-explored,
district-scale opportunity in the Northern Cape Province.”
Orion Minerals Limited (ASX/JSE: ORN) (Orion or the Company) is pleased to announce that it has intersected
base metal sulphides at two prospects within 15km of the proposed mill at the planned Prieska Copper-Zinc Mine
(PCZM), within the Prieska Copper-Zinc Project (Prieska Project), in South Africa’s Northern Cape.
Drilling was undertaken at the K3 and K6 prospects within the Kielder Project, located on the Dooniespan
prospecting right, which is located 15km north-west of the planned PCZM, within the Prieska Project (Figure 1).
1 The production target and forecast financial information were first reported in ASX announcement of 26 May 2020: “Updated Feasibility Study Delivers…”
available to the public on http://www.orionminerals.com.au/investors/asx-jse-announcements/. All material assumptions underpinning the production target
and forecast financial information in the initial report continue to apply and have not materially changed.
Mineralisation similar to that at the Prieska Project has been intersected at less than 200m from surface at both
K3 and K6 prospects (Figures 4 and 6). Massive, semi massive and disseminated base metal sulphide
mineralisation was intersected as follows:

The drill rigs have now moved to the northern Prospecting Rights where drilling will be carried out on the
Company’s Namaqua-Disawell and Masiqhame prospecting rights (Figure 1) at the Boksputs, Kantienpan and
Jacomynspan prospects. (refer ASX release 20 October 2020).

drilling program.
Prieska Project (Kielder)
Newmont South Africa (Newmont) discovered volcanogenic massive sulphide (VMS) style copper-zinc
mineralisation at three prospects on the Kielder Project in 1976.
The drilling records and exploration reports available to Orion are incomplete, but include reports of feasibility
study work for open pit mining and consideration by Anglovaal and Newmont of a potential joint venture, with
milling of the Kielder open pit ore to be undertaken at the nearby Prieska Copper Mine mill, that was operating
just 15km away at the time.
The tonnages and grades of the ore mentioned in the feasibility study reports cannot be verified by Orion due to
incomplete drilling and exploration records and are therefore not reported in this announcement.
Available Newmont reports indicate that K3 and K6 prospects had returned the best results with maximum
intersections of 4.8m @ 0.46% Cu, 6.18% Zn and 15g/t Ag from 116m in KDH15, at prospect K6, and 13.08m @ 0.23%
Cu and 3.69% Zn from 179.21m in KDH3, at prospect K3. A 1% Zn cut-off was used with no top-cut. Where present,
internal waste is included in the intersections (refer ASX release 20 October 2020).
Newmont drilling only tested the mineralisation at shallow depths with available data showing most of the
intersections at depths of less than 200m. At K3, Newmont drill tested up to the border of the tenement boundary.
The mineralisation potentially continues to the east of the boundary, where Orion has a pending prospecting
right application.
Apart from verifying the Newmont data, the holes drilled by Orion (Figure 2) will provide drill core for mineralisation
characterisation purposes and to provide a platform for follow-up down-hole geophysics.
Orion has demonstrated the value of applying modern, high-powered down-hole geophysics at the nearby
PCZM VMS deposit, where down-hole geophysics assisted in guiding drilling to define a current Mineral Resource
of 30.49Mt @ 1.2% Cu, 3.7% Zn in accordance with the JORC Code 2 (19.13Mt at 1.18% Cu, 3.59% Zn Indicated
Resources and 11.36Mt @ 1.2% Cu, 3.80% Zn Inferred Resources). Several remaining geophysical targets indicate
further extensions of the PCZM deposit at depths of >1,000m below surface (refer ASX release 25 February 2019).
The shallow depth of mineralisation and the strong potential for strike and dip extensions at K3 and K6 – with the
possibility of higher grades and thicknesses extending beyond the limited Newmont drilling grids – offers a
significant opportunity for Orion to delineate a shallow, near-mine deposit which could become a future source
of satellite ore feed to an expanded operation at PCZM.

Mr. Errol Smart. Competent Person: Orion’s Mineral Resource: Mr. Sean Duggan. Orion confirms it is not aware of any new information or data that materially
affects the information included in the original market announcement. Orion confirms that all material assumptions and technical parameters underpinning the
mineral resource estimates continue to apply and have not materially changed. Orion confirms that the form and context in which the Competent Person’s
findings are presented have not been materially modified from the original market announcement.
Figure 4: Cross-section showing the mineralisation intersected in drill holes OKD031 and OKD033 at the K3 Prospect.
Newmont reported its highest-grade drill intersections at Kielder at K6. While little of the Newmont historical drill
information is available to Orion (Figure 4 and Appendix 1), available reports do indicate that the Newmont
geologists found that the geophysical techniques available at the time, including electro-magnetic (EM) surveys,
failed to detect the mineralisation at K6, rendering geophysical targeting for down-dip and along strike
extensions virtually impossible at the time.
Orion drilled a diamond hole at K6 to obtain core for mineral classification purposes and also as a platform for
the application of modern high-powered geophysical methods (Figures 5 and 6).
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 copper and zinc grades.
