Orion reports maiden JORC Mineral Resource for the
Okiep Copper Complex, Flat Mines
Orion’s due diligence investigation verifies maiden Resource estimate and confirms outstanding potential for growth,
with exciting potential for extensions and high-priority EM targets located below the deposit.
- Maiden JORC Mineral Resource, classified and reported in accordance with the JORC Code (2012),
completed for three deposits (the Flat Mines) which form part of the Okiep Copper Complex, subject to
the recently announced option agreement (refer ASX release 2 February 2021).
- The Mineral Resource comprises 8.9Mt at 1.37% Cu, containing 122,000 tonnes copper; consisting of a
Measured Resource of 3,505,000 tonnes at 1.41% Cu, an Indicated Resource of 5,001,000 tonnes at 1.38%
Cu and an Inferred Resource of 401,000 tonnes at 0.84% Cu.
- The Mineral Resource has been verified by Orion’s due diligence investigations.
- The Mineral Resource is located on the South African Tantalum Mining (Pty) Ltd’s Mining Right
Application, over which Orion recently secured an option to acquire a 56.25% interest.
- The copper mineralisation has excellent potential for both strike and dip extensions.
- Potential for high-grade blows down-dip, where the intrusive host cuts favourable country rock
lithologies.
- High-priority drill targets identified below the Mineral Resource using the first-ever Drone Time Domain
Electromagnetic survey flown over the district, providing an outstanding exploration target.
Orion’s Managing Director and CEO, Errol Smart, commented on the results:
“This maiden JORC complaint Mineral Resource for our recently announced SAFTA transaction demonstrates the
enormous value locked up in the high-quality data contained in the O’okiep Copper Company archives. We
intend to unlock this value in the months ahead through a combination of further due diligence work on the
historical database, combined with modern exploration aimed at making new discoveries – bearing in mind that
this district has seen virtually no exploration in decades, with no modern high powered airborne geophysics
applied.
“The shallow depth of this initial Mineral Resource and, the fact that it is already accessed by decline
development and has stopes prepared for extraction is very positive and bodes well for early mine development
potential. The 2018 laborotory metallurgical testwork, undertaken by the project vendors, supports 2003 plant
records indicating the potential to recover >96% of copper to a high-quality sulphide concentrate.
“While we are now able to validate and state a maiden JORC Mineral Resource at Flat Mines, several additional
mineralised bodies have been drilled in close proximity and will require further evaluation before mineral resource
estimation can be undertaken.
“We have identified exciting potential to deliniate higher-grade mineralisation down-dip, where the mineralised
intrusive crosses key meta-sedimentary units, particularly in areas where this is supported by significant EM targets
located down-dip and along trend in the intrusive. We anticipate that these EM plates will have a much higher
sulphide content with likely higher copper grades compared with the Mineral Resource which has a moderate
to weak EM response in the drone survey.”

“Orion will now re-evaluate the positive feasibility studies completed by SAFTA in 2018 that were used to support
a mining works program and a Mining Right Application. Orion will also assist SAFTA to progress additional
Prospecting Right Applications that have been lodged to allow drill testing of compelling EM targets, while the
grant of the Mining Right is awaited.”
Further to its announcement of 2 February 2021, Orion Minerals Limited (ASX/JSE: ORN) (Orion or Company) is
pleased to report a maiden Mineral Resource estimate for three deposits that form part of the Okiep Copper
Project (Okiep Project). As announced last week, Orion has secured an option to acquire and consolidate
dominant ownership of this historic copper mining district.
The Mineral Resource, as stated in Table 1 below, is contained in three deposits referred to as Flat Mine North
(FMN), Flat Mine East (FME), and Flat Mine South (FMS). Verified historical drilling data was used in the Mineral
Resource estimation and the Mineral Resources are classified and reported in accordance with the 2012 Edition
of the Australian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC 2012) with
supporting information in Appendices 1 and 2.

Figure 1: SAFTA Prospecting and mining rights showing known mines/prospects and plethora of historical drill holes (green dots).
A total of 235 surface and 17 underground drill-holes totalling 43,413m of drilling at FMN, 80 surface holes
(32,750m) at FMS and 151 surface holes (51,414m) at FME were captured in the drilling database and were used
to model the maiden Mineral Resource (Figure 1, Table 2, a comprehensive set of sections and plans are
presented in Appendix 1 to provide further illustration).
Historical drilling was carried out by the O’okiep Copper Company (Pty) Ltd and Gold Fields of South Africa (Pty)
Ltd, two reputable South African mining companies during the 1980’s. Southern African Tantalum Mining (Pty)
Ltd’s (SAFTA) twin-drilling validation program in 2018 consisted of 13 surface holes (2,370m) (Table 3),
implementing modern QAQC measures which verified, confirmed and allowed the historical drill data to be used
for Mineral Resource estimation. Confidence in the geological and mineralisation models and continuity allowed
the incorporation and use of the entire drilling database. Additional drilling will be required to increase the
confidence and upgrade the Inferred Resources.
The Mineral Resource is located within the SAFTA mining right application and consists of three separate
mineralised deposits in close proximity to each other. Mineralisation is hosted by shallow, sub-surface bodies.
FMN consists of three continuous bodies with the Central Portion being flat-lying and striking north-south for
approximately 242m. The Southern Portion of FMN is 280m long and has no discernible dip and the Northern
Portion is 325m long. Mineralisation at FME has a strike of 1,740m and generally dips at 53° to the north-west. FMS
has an east-west strike of approximately 575m and dips steeply (75°) to the north.
At FMN, an existing decline runs into the Mineral Resource. The decline is in extremely good condition indicating
strong geotechnical conditions.
The Maiden Mineral Resource for the FMN, FME and FMS deposits were estimated utilising the following
parameters:
• The declared Mineral Resource is primarily based on the historical drill data as available at September
2018. The data consists of 252 (43,413m) holes for FMN, 80 (32,750m) holes for FMS and 151 (51,414m) holes
for FME. An additional 13 twin holes were drilled in 2018 and also used in the estimation.
• Historical diamond AX or BQ whole core were used for analysis of grades. Where AX core was drilled,
whole core were sampled and in the case of BQ core, core were split. Twin holes drilled by SAFTA were
NQ size and core were split in half.
• Historical samples were prepared and analysed at the on-mine laboratory in Nababeep. SAFTA twin drill
core samples were analysed at ALS Chemex Pty Ltd (ALS) in Johannesburg, South Africa.
• No QAQC records are available for the historical samples analysed. CRMs, blanks and duplicates were
inserted and analysed for all the SAFTA twin drill holes samples. CRMs, blanks and duplicates comprised
15% of all field samples, i.e. approximately 5% of each. ALS has their own internal QAQC protocols which
include 5% CRMs, 2.5% blanks and 2.5% duplicates.
• All historical collars were surveyed using a total station theodolite by a qualified surveyor. The SAFTA twin
hole collars were surveyed by a qualified surveyor using a differential GSP.
• The 2018 twin down-hole surveys were surveyed using a “Peewee” instrument and later holes using the
non-magnetic “Devico” survey instrument. Surveys were done by an independent survey company.
Down hole surveys of the historic holes were done using and Eastman survey tool.
• Mineralised zones for all three deposits (FMN, FME & FMS) were delineated by using a 0.7% Cu cut-off
grade.
• Samples were composited to 1m, with only two Cu outliers capped for FME (15% Cu upper cap) and
eight outliers for FMS (7% Cu upper cap).
• Interpolation of the composite data was used to calculate block Cu grades using omni-directional
variograms and Inverse Distance Squared estimation.
• Block model cells of 2m x 2m x 2m were used for FMN and FMS whereas 4m x 2m x 2m for FME. No sub-
celling and rotations were applied.
• Relative densities (t/m3) were determined using the Archimedes method by weighing the core in air and
water respectively. Average densities were applied and were not estimated.
• These shallow sulphide resources are classified as Measured, Indicated and Inferred. Cognisance was
taken of the potential uncertainties related to mineralised envelope delineation and therefore the
associated volume estimation, as well as that most of this resource estimation is based on historical data.
There is excellent potential to define additional resources along strike and down-dip and strong potential for
additional sulphide deposits within SAFTA’s prospecting and mining rights (Figure 1). A Drone Time Domain
Electromagnetic (Drone TDEM) survey carried out in 2018 identified high priority drill targets along strike and below
the current resource at Flat Mine North (Figure 2). Orion’s exploration team is evaluating and prioritising such drill
targets for follow up drill programs.
The Cu-bearing resource at Flat Mine North (FMN) was surveyed simultaneously as a Time Domain
Electromagnetic (TDEM) and magnetic target with the cutting-edge Geometrics Cs-Vapour MagArrow
instrument, flown by a DJI 600 PRO hexacopter. At the time in 2018, this was a world first survey of its kind, with
TDEM and magnetic surveying undertaken simultaneously using a drone flight platform. The flight line spacing at
FMN was 50m, the flight height was ~15m and the drone copter velocity was ~3m/s.
