Encouraging Drilling Results Received from the IGO-ORN Joint Venture Tenements – Fraser Range, Australia
Mafic–ultramafic intrusive rocks intersected in highly prospective settings in all five diamond holes drilled at
the North West Passage and Pike Nickel-Copper prospects.
Injected sulphide veins characteristic of magmatic sulphide nickel-copper systems observed in drill core from
the North West Passage.
Mafic–ultramafic bodies intersected at Hook 1, located 16km north-east of Legend Mining’s recently
announced massive sulphide nickel-copper discovery.
Strong untested off-hole conductor at Hook 1 offers a compelling drill target.
Additional drilling planned for the 2020 field season.
Orion’s Managing Director and CEO, Errol Smart, commented:
"We are very encouraged by the progress being made by IGO in their ongoing exploration of our Fraser Range
joint venture tenements in WA. The results from the drilling completed towards the end of last year provide further
strong indications that we are in the right place to discover a large magmatic nickel-copper sulphide system –
with all five diamond holes intersecting mafic-ultramafic intrusive bodies.
“We have long held the view that the Fraser Range would yield further significant discoveries outside of the Nova-
Bollinger deposit – a belief that first led us to secure these tenements several years ago. With exploration attention
once again focusing on the belt following the recently reported massive sulphide discovery by Legend Mining,
just 16km from our Hook 1 prospect, we are looking forward to the next phase of drilling planned by IGO this field
season.”
Orion Minerals Limited (ASX/JSE: ORN) (Orion or the Company) is pleased to announce encouraging diamond drill
results received from the IGO Limited (IGO) IGO-ORN joint venture (JV) on the North West Passage, Hook 1 and 2
and Pike prospects, located within the Fraser Range Belt (Figure 1) (refer ASX release 10 March 2017).
Drilling completed towards the end of 2019 tested several moving-loop electromagnetic (MLEM) conductors,
anomalous basement geochemical anomalies and magnetic features on magmatic nickel-copper targets, as
well as a Volcanogenic Massive Sulphide (VMS) copper-zinc target at Pike (refer ASX release 31 October 2019).
Orion is very encouraged by the results received from this drilling, with all five diamond holes completed
intersecting mafic-ultramafic intrusive bodies.
Orion considers the presence of anastomosing sulphide veins, sulphide-bearing graphite-rich horizons and meta-
carbonates as intersected in the host rocks to the mafic-ultramafic bodies to be the ideal setting for the discovery
of magmatic massive nickel-copper sulphide deposits.
Further information on the prospects tested, and the drilling results received to date, is provided below.
Figure 1: IGO-ORN Fraser Range Joint Venture Tenements showing Prospects and drill holes.
North West Passage
The North West Passage target was initially identified by Orion in a 2014 versatile time domain electromagnetic
(VTEM) survey and was interpreted further by IGO using additional geophysical data, including aeromagnetics
and ground gravity.
Two diamond drill-holes, 19AFDD1001 and 19AFDD1002, tested a steeply dipping 600m x 200m plate of 2,000
siemens, detected by a MLEM survey in 2017 (Figure 2).
The specifications of the survey are shown in Table 1 and details of the holes are summarised in Table 2, both
below.
Hole 19AFDD1001 intersected mafic-ultramafic intrusive rocks intercalated with carbonate and graphitic meta-
sediments.

Multi-phase ultramafic assemblages intrusive into carbonatitic and graphitic sub-units are considered to be highly
prospective for magmatic nickel-copper mineralisation within the Fraser Range.

Hole 19AFDD1001
Geological logging and interpretation of assay results from 131 quarter core samples show three intervals of mafic-
ultramafic intrusions.
Interval A, from 160m to 215m down-hole, returned maximum values of 2,350ppm Ni, 2,350ppm Cr and 28% MgO
and consists of serpentinized mafic-ultramafic units intermingled with carbonate and graphitic sub-units. The
interval contains visible sulphides with massive and semi-massive pyrrhotite-pyrite stringers injected into both
serpentinized ultramafic rock and its host rocks. A semi-massive mineralised vein from 169.4m-169.8m down-hole,
composed of pyrrhotite and pyrite with trace chalcopyrite blebs, is shown in Figure 3.
Interval B, developed between 240m and 253m down-hole is composed of mafic to ultramafic rocks with vein-
hosted pyrite and pyrrhotite.
Interval C, from 267m to 278m down-hole, consists of peridotite and is devoid of sulphide. Maximum values include
2,130ppm Ni, 2,380 ppm Cr and 34% MgO.
Further assessment of the geochemical results is underway.

Hole 19AFDD1002
The hole intersected three mafic-ultramafic intrusive bodies between 99.75m down-hole and the end of the hole
at 409m. 139 core samples were submitted for analysis. Interpretation of the geochemical results is in progress.
Pike Prospect – E28/2367
Three diamond drill holes were completed on the prospect with a total of 1,038m drilled (Table 2). Drilling was
aimed at explaining MLEM conductors, magnetic anomalies and Cu and Zn bedrock anomalies (Figure 4).

Drill Hole 19AFDD1008 – Hook1
Hook 1 lies 16km north-east of Legend Mining’s new massive sulphide nickel-copper discovery at the Area D
Prospect (Figure 5).
Hole 19AFDD1008 targeted a 7000 siemens conductor. The hole intersected amphibole-rich gabbronorite and
meta-gabbronorite zones intercalated with meta-sediment that is locally graphitic. Stringers and 10cm thick veins
of semi-massive pyrrhotite – pyrite with minor occurrences of chalcopyrite occur with the graphitic horizons (Figure
6).
Rare occurrences of native copper were noted in the amphibole rich gabbronorite. The intersections of
gabbronorite zones vary from 6m to 57.5m
The presence of stringer sulphides within graphite-bearing meta-sediments and mafic-ultramafic intrusives
warrants follow-up. The intrusives hosting nickel mineralisation at Legend Mining’s Area D discovery occur within a
bedded meta-sediment package containing graphitic units.
A DHEM survey of 19AFDD1008 was completed in November 2019. Modelling of the data highlighted several off-
hole responses, of which a strongly conductive response beneath the end of the hole offers a compelling target.
Deepening of the current hole by approximately 180m is required to test the strongly conductive plate model
located directly beneath the drill-hole.

Drill Hole 19AFDD1009 – Pike 4
Diamond drill hole 19AFDD1009 targeted a strike extensive 7000 siemens conductor loosely coinciding with an
11km long linear magnetic high on the Pike 1 prospect.
Bedrock lithologies below the 150m cover sequence and saprolite consisted of an intercalated package of
metamorphosed gabbronorite and meta-sediment. Gabbronorites displayed minor pyrrhotite and chalcopyrite.
DHEM surveys confirm that semi-massive graphite intersected between 307.5m to 330.8m down-hole explains the
electromagnetic (EM) conductor.
Drill Hole 19AFDD1010 – Hook 2
Located 1km north of the Hook 1 prospect, this drill hole aimed to test a basement copper and zinc geochemical
anomaly. The hole intersected basement lithologies consisting of banded graphite and pyrite bearing meta-
sediment and meta-gabbronorite. The hole terminated in meta-gabbronorite.
Proposed Drilling
IGO plans to drill a further 2,560m in six holes, including extending hole 19AFDD1008 to test a strong off-hole
conductor detected below the current end-of-hole depth.
Holes are also planned to test further EM targets at the North West Passage, Hook, Pike Eye and Pike (Figure 7). At
Garfish, a gravity anomaly will be drilled to test for a mafic – ultramafic intrusive.
