ASX ANNOUNCEMENT

ASX : CXO

23[rd] January 2015

Drill results received for Virginia and Copper Royals

HIGHLIGHTS

  • Results for the Virginia and Copper royals received from Core’s preliminary RC drill program completed in late 2014

  • Core’s drilling has intersected elevated copper related to chargeable IP targets at Virginia

  • Drill results have confirmed presence of inconsistently mineralised structure at depth at Virginia, below surface geochemical anomalism

  • Anomalous copper and zinc levels in drilling, but no zones of significant mineralisation identified

  • Core will now move its immediate focus onto the Jervois Domain Project : final AEM data expected in the next few days

  • Analysis and modelling of the Jervois Domain AEM data will be used to prioritise and refine targets prior to drill testing planned in March 2015

Core Exploration Ltd (ASX:CXO) has received all RC drill results from its recent reverse circulation (RC) drilling at its Virginia Prospect and Copper Royals district in the Northern Territory.

Core completed the Company’s first drilling program at the Virginia Prospect in late 2014 in an area never drilled before. Core’s RC drilling at Virginia was aimed at testing the source of the elevated copper in outcrop and soil geochemistry mapped for over 1.5 km of strike at Virginia.

Twelve RC holes were drilled at the Virginia Prospect and six RC holes at Copper Royals for a total of 1,745 metres to depths up to 120 metres (Figures and Tables 1 & 2).

Drilling at Virginia tested the IP chargeability anomalies from Core’s 2014 IP survey along two traverses and tested the peak of the preliminary Channel 25 conductive anomaly that is coincident with the central section of the Virginia Prospect.

Drill results have confirmed an inconsistently mineralised structure at depth at Virginia below surface geochemical anomalism related to the chargeable zones in Core’s previous IP geophysics. Downhole geology is interpreted as cyclical sequences of variably garnet and silica altered Riddock Amphibolite that dip approximately 10°‐20° to the northwest.

Core’s drilling at Virginia has intersected sulphide mineralisation comprising fracture filling and disseminated pyrite (iron sulphide) which is common throughout and localised chalcopyrite (copper sulphide). Malachite and azurite (copper carbonate) minerals extend from surface to 10‐20m metres depth.

Core also completed a reconnaissance drilling program at Copper Royals to follow on from the Virginia drilling program to test new targets with a single hole to determine potential for future follow‐up. Occasional anomalous levels of copper and zinc were intersected by drilling at the Copper Royals, but no significant mineralised zones were intersected in drilling.

An increase of sulphides around coarse‐grained garnet porphyroblasts was evident in some holes, which accounts for the chargeable IP anomalies, but was variable and therefore challenging to define favourable mineralised stratigraphic layering.

It is suggested that hydromorphic mobilisation of copper from the amphibolite package at Virginia and Copper Royals has brought elevated levels of copper to the surface that outcrops as distinct copper carbonates. This process seems to be in contrast to Core’s previous drill results at Inkheart 40km to the south, where drilling intersected a consistently mineralised sulphide system at depth.

The Company will now focus on the Jervois Project and anticipate receiving final AEM results in the next week. The analysis and modelling of the new AEM data will be utilised to prioritise and refine targets prior to drill testing planned to commence in March 2015.

Virginia Prospect Discussion

The twelve drill holes at Virginia were primarily designed to test a number of chargeable anomalies identified in the Induced Polarisation survey CXO collected in early 2014 which indicated a shallow north westerly dip to a potentially mineralised sequence of Riddock Amphibolite.

Two drilling traverses were completed and in addition two holes were targeted under the central portion of the surface geochemical anomaly where visible malachite and azurite staining is common in outcrop.

Geologically, Virginia comprises cyclical sequences of Riddock Amphibolite with variable coarse‐ grained garnet and silica alteration that overlie biotite‐plagioclase‐quartz gneiss and minor calc‐ silicate units of the Lower Harts Range Group.

Unfortunately the results overall were disappointing with the chargeable features explained by disseminated and fracture coatings of pyrite (iron sulphide). Whilst a few significant copper intersections were encountered on the westerly traverse as reported (ASX 23/12/14) the eastern traverse and central holes did not return any significant intersections and only showed inconsistent broad zones of very weakly elevated copper and zinc.

Copper Royals Discussion

Core planned a six hole reconnaissance drilling program to follow on from the Virginia drilling program to test new targets in the Copper Royals district with a single reconnaissance hole to determine potential for future follow‐up.

Prior to drilling, Core conducted a re‐evaluation of the previous exploration work by Tanami Gold, who drilled 230 RAB holes (6,843m) in 2002. The re‐evaluation highlighted that the majority of the surface geochemical anomalies were adequately tested which included extensive drilling at Copper King and Copper Queen Prospects to depths approaching 100 metres.

Also of note within the Copper Royals district, access can be a constraining factor due to very rugged terrain with extreme relief.

Anomalous levels of copper and zinc were intersected by drilling at the Copper Royals, but no significant mineralised zones were interested in drilling.

In cases where ‘industry standard’ work has been done this would be
relatively simple (egg ‘RC drilling was used to obtain 1 m samples
from which 3 kg was pulverised to produce a 30 g charge for fire
assay’). In other cases more explanation may be required, such as
where there is coarse gold that has inherent sampling problems.
Unusual commodities or mineralisation types (egg submarine
nodules) may warrant disclosure of detailed information.

Drill hole
Information
A summary of all information material to the understanding of the

metres) of the drill hole collar
o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
Drill hole information is recorded within the CXO in-house database
with all collar locations listed in the table accompanying this
document.
No material information is excluded.

10

Criteria JORC Code explanation Commentary
If the exclusion of this information is justified on the basis that the
information is not Material and this exclusion does not detract from
the understanding of the report, the Competent Person should clearly
explain why this is the case.
Data
aggregation
methods
In reporting Exploration Results, weighting averaging techniques,
maximum and/or minimum grade truncations (e.g. cutting of high
grades) and cut-off grades are usually Material and should be stated.
Where aggregate intercepts incorporate short lengths of high grade
results and longer lengths of low grade results, the procedure used
for such aggregation should be stated and some typical examples of
such aggregations should be shown in detail.
The assumptions used for any reporting of metal equivalent values
should be clearly stated.
Aggregated intersections have been calculated for copper and lead
using a 0.1% cut-off. Minimum intersection widths are 3m and up to
3m of internal dilation are included
No metal equivalents are reported.
Relationship
between
mineralisatio
n widths and
intercept
lengths
These relationships are particularly important in the reporting of
Exploration Results.
If the geometry of the mineralisation with respect to the drill hole
angle is known, its nature should be reported.
If it is not known and only the down hole lengths are reported, there
should be a clear statement to this effect (e.g. ‘down hole length, true
width not known’).

Initial reconnaissance drilling only thus geometric relationship of
mineralisation to vertical drill orientation unknown.
Diagrams Appropriate maps and sections (with scales) and tabulations of
intercepts should be included for any significant discovery being
reported These should include, but not be limited to a plan view of
drill hole collar locations and appropriate sectional views.
See attached plans showing drill hole density and sections as well as
the tabulated drill hole information data accompanying this document.
Balanced
reporting
Where comprehensive reporting of all Exploration Results is not
practicable, representative reporting of both low and high grades
and/or widths should be practiced to avoid misleading reporting of
Exploration Results.
See attached table of intersections.
Reported intersections use the criteria detailed in the above section
“data aggregation methods”.
Other
substantive
exploration
data
Other exploration data, if meaningful and material, should be reported
including (but not limited to): geological observations; geophysical
survey results; geochemical survey results; bulk samples – size and
method of treatment; metallurgical test results; bulk density,
groundwater, geotechnical and rock characteristics; potential
deleterious or contaminating substances.
Due to the drilling technique primary textures are hard to distinguish
or are obliterated.
Significant groundwater was present in VGRC002 and VGRC003
below 50m depth.
 Multi-element geochemistry assaying (47 elements) including gold by
fire-assay is routine for all sampling. Some elemental associations
are recognised within certain lithologies within the region and are
