ASX ANNOUNCEMENT ASX: CXO

27[th] November 2017

Wide High-Grade Lithium Drill Intersections at BP33

HIGHLIGHTS

  • High-Grade Lithium drill assays received from BP33, including:

  • 54m @ 1.42% Li2O from 101m in FRC103

  • 46m @ 1.51%Li2O from 66m in FRC104

  • The high grade lithium intersections represent some of the widest spodumene intersections ever drilled in the Northern Territory

  • Results confirm that BP33 spodumene pegmatite is open along strike both to the north and to the south, and is thicker at depth than anticipated

  • Awaiting assays for the next 25m drill interval in FRC104 (112m-137m) and also FRC105

  • Diamond Drilling has commenced immediately at BP33 to undertake followup drilling and will continue to allow for an initial Resource estimate for BP33

  • Additional drill assays from BP33 expected to be received over coming weeks

  • BP33 located only 5km from the Grants Lithium Deposit

  • Core expects BP33 to be added to the Company’s Lithium Resources at the Finniss Lithium Project

Core Exploration Ltd ( ASX: CXO ) (“ Core ” or the “ Company ”) is pleased to announce that, following its announcement last week of wide pegmatite intersections at Core’s 100% owned high grade BP33 pegmatite, it has now received the assay results which confirm the presence of wide, high grade spodumene at BP33.

BP33 is located on the Company’s newly acquired Bynoe lithium project near Darwin. Core’s new assays reflect the widest pegmatite intervals that have ever been drilled at BP33, and amongst the widest spodumene bearing intersections ever drilled in the Northern Territory.

New assay results from BP33 include an outstanding intersection of 54m @ 1.4% Li2O in spodumene pegmatite from 101m in RC Drillhole FRC103.

At the northern end of BP33, a high grade spodumene intersection of 46m @ 1.51% Li2O was returned from 66m-112m downhole in FRC 104. An additional 25m of assays are awaited from the remainder of FRC104 from 112m to 137m (Figure 1).

A 36m intersection grading 0.74% Li2O from 73m was received for hole FRC102 (0.1% cut-off), including a high-grade intersection 16m @ 1.40% Li2O from 146m. However, poor sample return and contamination was noted during drilling of FRC102m, which is interpreted to have smeared and diluted the lithium assays. Core is planning to re-drill nearby to this hole with diamond core to confirm geology with the assay grade.

The new assays confirm Core’s visual assessment of the mineralogy of the RC drill chips (ASX 16/11/2017) that much of the BP33 pegmatite contains high grades of spodumene pegmatite.

Results from the recent RC drilling also confirm that BP33 spodumene pegmatite is open along strike both to the north and to the south and is thicker at depth than expected (Figure 2).

Figure 2. Drill locations and tenement boundary mid-way through BP33 Pegmatite.

Based on Core’s new drill results, a revised cross section can be drawn (Figure 1) that suggests a down-dip doubling of true thickness of the pegmatite in the north (20m at surface vs 40m at depth). On this basis, the Company believes that an alternate geometrical/structural scenario may exist more broadly to the north and will address this via further drilling.

Most recent RC Drillhole FRC105 targeted the southern extension of BP33 and intersected pegmatite to end of hole (EOH), where 8m of pegmatite was intersected from 116m to the EOH at 124m before drilling problems caused the hole to terminate (Figure 2).

Next Steps at BP33

Follow-up diamond core drilling is now underway at BP33. The diamond drilling is aimed at defining the continuity of grade and scale of the spodumene mineralisation at BP33 and the drill core will also provide valuable information that may be used for metallurgical testwork and resource evaluation at BP33.

Previous drilling by Core at BP33 was hindered by the location of the historic tenement boundary approximately mid-way through the deposit. With Core recently acquiring 100% of the adjoining tenements, it now can fully explore the BP33 deposit without the complications of the previous disjointed ownership.

Remaining drill assays from the recent RC drilling at BP33 are expected over coming weeks and assays from the diamond drilling is expected in early 2018.

Commenting on drilling at BP33, Core’s Managing Director, Stephen Biggins said:

“The acquisition of the Bynoe Lithium Project is delivering immediate results for Core. These high-grade lithium intersections are very significant and demonstrate the potential of BP33 in a similar manner to Grants.

Given the success of this recent drilling, we now intend to undertake additional drilling at BP33 with the aim of determining the full extent of BP33 and adding to Core’s lithium resources in the NT. We will also be testing an alternate geometrical/structural scenario may exist more broadly to the northern end of BP33 which has the potential to significantly increase the potential scale of BP33.”

JORC Code, 2012 Edition – Table 1 Report Template

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections)

Criteria JORC Code Explanation Commentary
Sampling
techniques
Nature and quality of sampling (e.g. cut channels, random chips, or specific
specialised industry standard measurement tools appropriate to the
minerals under investigation, such as down hole gamma sondes, or
handheld XRF instruments, etc.). These examples should not be taken as
limiting the broad meaning of sampling.
Include reference to measures taken to ensure sample representivity and the
appropriate calibration of any measurement tools or systems used.
Aspects of the determination of mineralisation that are Material to the
Public Report.
In cases where ‘industry standard’ work has been done this would be
relatively simple (e.g. ‘reverse circulation 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 (e.g. submarine nodules) may warrant
disclosure of detailed information.
 Drilling geology results reported herein relate to RC drillholes at the BP33
Prospect on ELs 29698 and 30015
 Holes FRC102 to FRC104 were drilled by Core in November 2017, and

 Metallic Lithium percent was multiplied by a conversion factor of
2.15283/10000 to report Li ppm as Li2O%
 No assaydata referred to in relation to historic Greenbushes Ltd drilling.
Location of
data points
Accuracy and quality of surveys used to locate drill holes (collar and down-
hole surveys), trenches, mine workings and other locations used in Mineral
Resource estimation.
Specification of the grid system used.
Quality and adequacy of topographic control.
 Core’s Drilling: All coordinate information was collected using hand held
GPS utilizing GDA 94, Zone 52. RC hole traces were surveyed by north
seeking Champ gyro tool (multishot mode at 5m and 10m intervals)
operated by the drillers and the collar is oriented by a line of sight compass
and a clinometer. Drill hole deviation has been minor to moderate for hole
FRC103-104 and is acceptable for regional exploration and resource drilling.
Hole FRC102 deviated from its planned course significantly but the gyro
down hole survey has accurately recorded its trace and it is acceptable for
regional exploration and resource drilling.
 Greenbushes Drilling: All coordinate information was collected by
Greenbushes Ltd using hand held GPS utilizing AMG66, Zone 52. Core has
subsequently undertaken a datum transformation to convert to MGA94
Zone 52. A number of the drill collars have been located on the ground and
the coordinates verified using more precise modern GPS (accuracy 3-4 m).
Approximately 10-15 m of further correction was required to bring the
entire set of collar coordinates into alignment with the current datum.
Interrogation of the data in GIS space indicates excellent alignment with
position of pegmatite boundaries in the pit and in Core’s drilling.
Data spacing
and
distribution
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to establish the
degree of geological and grade continuity appropriate for the Mineral
Resource and Ore Reserve estimation procedure(s) and classifications
applied.
Whether sample compositing has been applied.
 Drill collars are spaced approximately 50m apart along the northeasterly
trending pegmatite body of BP33.
 This data may be used to support a resource.
 Refer to figures in report.
 Sample compositing reported here are calculated length weighted averages
of the 1 m assays. Length weighted averages are acceptable method
because the densityof the rock(pegmatite)is constant.

Orientation of
data in
relation to
geological
structure
Whether the orientation of sampling achieves unbiased sampling of possible
structures and the extent to which this is known, considering the deposit
type.
If the relationship between the drilling orientation and the orientation of key
mineralised structures is considered to have introduced a sampling bias, this
should be assessed and reported if material.
 Core’s drilling is oriented perpendicular to the interpreted strike of
mineralization (pegmatite body) as mapped or predicted by the geological
model. In some areas the rocks may trend at an angle to the drill traverse.
Because of the dip of the hole, drill intersections are apparent thicknesses
and overall geological context is needed to estimate true thicknesses.
 Greenbushes’ Drill holes are inclined and were drilled from West to East,
and are therefore oblique to the strike of the NE-trending BP33 pegmatite.
None-the-less, modern GIS software is easily able to visualize these in 3
dimensions and integrate the drill traces with more recently surveyed
drilling by Core and Liontown, which were oriented approximately
perpendicular to the interpreted strike of the mineralised trend.
Sample
security
The measures taken to ensure sample security.  Company geologist supervises all sampling and subsequent storage in field
and transport to point of dispatch to assay laboratories.
 No assaydata referred to in relation to Greenbushes Ltd drilling.
Audits or
reviews
The results of any audits or reviews of sampling techniques and data.  Audits or reviews of the sampling techniques were not undertaken

parties
Acknowledgment and appraisal of exploration by other parties.  The history of mining in the Bynoe Harbour – Middle Arm area dates back
to 1886 when tin was discovered by Mr. C Clark.
 By 1890 the Leviathan Mine and the Annie Mine were discovered and
worked discontinuously until 1902.
 In 1903 the Hang Gong Wheel of Fortune was found and 109 tons of tin
concentrates were produced in 1905. In 1906, the mine produced 80 tons
of concentrates, but it was exhausted and closed down the following year
after a total of 189 tons of concentrates had been won.
 By 1909 activity was limited to Leviathan and Bells Mona mines in the area
with little activity in the period 1907 to 1909.
 Renewed activities in 1925 coincided with the granting of exclusive
prospecting licences over an area of 26 square miles in the Bynoe Harbour –
West Arm section but once again nothing eventuated.
 The records of production for many mines are not complete, and in
numerous cases changes have been made to the names of the mines and
prospects which tend to confuse the records still further. In many cases the
published names of mines cannot be linked to field occurrences.

 In the early 1980s the Bynoe Pegmatite field was reactivated during a
period of high tantalum prices by Greenbushes Tin which owned and
operated the Greenbushes Tin and Tantalite (and later spodumene) Mine in
WA. Greenbushes Tin Ltd entered into a JV named the Bynoe Joint Venture
with Barbara Mining Corporation, a subsidiary of Bayer AG of Germany.
 Greenex (the exploration arm of Greenbushes Tin Ltd) explored the Bynoe
pegmatite field between 1980 and 1990 and produced tin and tantalite
from its Observation Hill Treatment Plant between 1986 and 1988. An
abandoned open cut to 10m depth remains at BP33.
 They then tributed the project out to a company named Fieldcorp Pty Ltd
who operated it between 1991 and 1995.
 In 1996, Julia Corp drilled RC holes into representative pegmatites in the
field, but like all of their predecessors, did not assay for Li.
 Since 1996 the field has been defunct until recently when exploration has
begun on ascertaining the lithium prospectivity of the Bynoe pegmatites.
 The NT geological Survey undertook a regional appraisal of the field, which
was published in 2004 (NTGS Report 16, Frater 2004).
Geology Deposit type, geological setting and style of mineralisation.  The tenements cover the northern portion of a swarm of complex zoned
rare element pegmatite field, which comprises the 55km long by 10km wide
West Arm – Mt Finniss pegmatite belt (Bynoe Pegmatite Field; NTGS Report
16). The main pegmatites in this belt include Mt Finniss, Grants, BP33, Hang
Gong and Sandras
 The Finniss pegmatites have intruded early Proterozoic shales, siltstones
and schists of the Burrell Creek Formation which lies on the northwest
margin of the Pine Creek Geosyncline. To the south and west are the
granitoid plutons and pegmatitic granite stocks of the Litchfield Complex.
The source of the fluids that have formed the intruding pegmatites is
generallyaccepted as beingthe Two Sisters Granite to the west of the belt,

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.
 Sample compositing reported here are calculated length weighted averages
of the 1 m assays. Length weighted averages are acceptable method
because the density of the rock (pegmatite) is constant.
 0.4% Li2O was used as lower cut off grades for compositing with allowance
for including up to 5 intervals of below cut-off grade internal dilution. No
lower cut-off was used in interval 73m-179m in FRC102

These relationships are particularly important in the reporting of Exploration
Results.
 There are no references in relation to assay intercepts in the Greenbushes
Ltd drilling.

mineralisation
widths and
intercept
lengths
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’). _
 The oblique nature of drillholes with respect to geology is discussed above.
Because of the dip of the hole, drill intersections are apparent thicknesses
and overall geological context is needed to estimate true thicknesses. Refer
figures in report
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 figures in release
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.
 Exploration results are discussed in the report and shown in figures.
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.
 See release details.
 All meaningful and material data reported.
Further work The nature and scale of planned further work (e.g. tests for lateral
extensions or depth extensions or large-scale step-out drilling).
Diagrams clearly highlighting the areas of possible extensions, including the
main geological interpretations and future drilling areas, provided this
information is not commercially sensitive.
 Core has just commenced a Diamond core drilling program at BP33, as
outlined in this report.
 Further RAB drilling, RC and Diamond core drilling is on-going or planned in
this area to define additional targets at BP33 and extensions to the north
and south.
