Geological interpretation of historic exploration data puts spotlight on high priority targets at the
Okiep Copper Project
Target generation on the Okiep Project delivering high-priority drill targets
- Due diligence work at the Okiep Copper Project has defined high priority drill targets on the Carolusberg
Koperberg line.
- The Carolusberg – Koperberg line was first discovered in 1680 and subsequent workings have been
intermittently mined from 1850-2001.
- The Carolusberg – Koperberg workings contributed approximately 35% of the total post World War II
production of 105Mt of copper ore produced by the O’Okiep Copper Company (OCC).
- Newmont and subsequently Goldfields, who were the owners of OCC, undertook extensive drilling and
geological mapping during their tenure.
- Paper records of the historic exploration have now been digitised and are being modelled by Orion.
Orion’s Managing Director and CEO, Errol Smart, commented on the results:
“Our geological team at OCP continue to unpack huge value from the historic data that we have secured.
Using modern 3D GIS modelling, we are able to get a better understanding of the geological controls which
assist in identifying high priority targets for drill testing.
“We have already demonstrated that the high-quality data allows us to fast-track the re-estimation of resources
using historic drill data with a Mineral Resource of 11.5Mt @ 1.4% Cu already reported in accordance with JORC
2012 (refer ASX / JSE release 29 March 2021). This Resource was confirmed within three months of securing options
on the mineral rights and the historic data. Resource estimation work is continuing under the guidance of Mr Paul
Matthews, who has joined Orion as Group Mineral Resource Manager.
“I am particularly thrilled to be working with Paul again, as he was a key member of the contracted team that
helped us identify the early potential at Prieska. Paul’s early resource estimates for Prieska, back in 2015, have
proved to be accurate after extensive follow up drilling and resource estimation. Paul is a very experienced
Mineral Resource Manager and has joined us full time.
“Our attention at OCP is now turning to identifying high-quality targets for undiscovered high-grade deposits
such as those historically discovered in the Okiep district including the Okiep Mine (that gave the district its name)
which yielded 907,000 tonnes of sulphide ore at 21% copper, and Nababeeb South which yielded 816,000 tonnes
at 5.5% copper. We are focusing on similar geological settings to that of Okiep and Nababeeb South and have
identified high-priority targets to be tested on the BCC property which is currently under option to Orion.
“These high-grade deposits are usually found in pipes or blows and have very small dimensions of 150m - 250m
diameter and were easily missed by historic wide-spaced drilling.”
Okiep Copper Project
Orion Minerals Limited (ASX/JSE: ORN) (Orion or Company) is pleased to advise that it has identified new high-
priority drill targets on the Carolusberg – Koperberg complex that form part of the Okiep Copper Project (OCP),
located 570km north of Cape Town in the Northern Cape Province of South Africa. The Carolusberg – Koperberg
Complex is situated 20km southeast of the Flat Mine Complex that hosts the current OCP Mineral Resources base
of 11.5Mt at 1.4% Cu for 159,000 tonnes of contained copper (refer ASX / JSE release 29 March 2021) (Figure 1).
The targets were identified during ongoing due diligence investigations being undertaken by Orion on the
extensive database recently secured (refer ASX / JSE release 15 February 2021).
Figure 1: Locality map showing the Carolusberg – Koperberg and Flat Mine Complexes.
The following targets are currently being prioritised for exploration follow-up:
Koperberg – Carolusberg (Bulletrap PR)
• Shallow, potentially open pit targets (1, 2 and 3 on Figures 3 and 4) defined by:
o basic rock type outcrops with visible copper oxide mineralisation (Figure 2); and
o targets above historical mined areas not tested by historic drill holes.
• Deeper underground targets (4, 5 and 6 on Figures 3 and 4) defined by:
o the upper and lower contacts of the favourable Springbok Quartzite / Schist horizon along the
Koperberg – Carolusberg line of mafic intrusions (refer ASX / JSE release 2 February 2021). This is
the same geology as Okiep, Nababeeb South and Carolusberg Deeps;
o a large undrilled area above drill intercepts (Appendix 1, Table 2) located immediately west of
Carolusberg Deep; and
o a large untested area adjacent to drill intercepts (Appendix 1, Table 2) located east of
Carolusberg Deep and below Carolusberg East.
In addition, the line of mafic bodies extending west – southwest and east – northeast from the Koperberg East
Deposit, warrants follow-up drilling. Two preliminary targets, 7 and 8 on Figure 3, have been prioritised.

In addition to the drill targets identified on the Carolusberg – Koperberg line, Orion is currently evaluating the
potential of drill targets described in Table 1 below and shown on Figure 1:

drilling was carried out on the prospect.
Table 1: Potential drill targets (as shown on Figure 1).
The due diligence work completed on OCP in only a few months since securing options to acquire the large
tenement package and an extensive database, has highlighted how prospective the project area is for the
discovery of new high grade and large tonnage copper deposits.
