Core Exploration Ltd (ASX: CXO) (“Core” or the “Company”) is pleased to announce that it has received further high grade lithium assays from its Phase 2 RC regional drilling program at the Company’s 100% owned Finniss Lithium Project near Darwin in the NT (“Finniss”).
In this most recent batch of RC results received, lithium grades have been demonstrated in assays received from drilling at the Ahoy, Ahoy East and Far West prospects, which now brings Core’s known lithium bearing pegmatites to 6, from a total of 7 drilled to date within the Finniss Project area.
Core’s Managing Director, Mr Stephen Biggins commented:
“The high rate of success we are having in this emerging lithium province is a testament to the skills of our exploration team in generating and working up the initial exploration targets, and our early mover advantage in locking up strategic tenements in the Bynoe field early in 2016.
We now have confirmation of spodumene mineralisation on at least 6 prospects within our Finniss Project, and importantly, we have many more pegmatites on our tenure still to test, some of which have very significant scale potential”.
– Regional Phase 2 RC Drilling Results Progress Report
Lithium assay results from Core’s Phase 2 regional drilling targets at the Finniss Lithium Project has demonstrated that most pegmatite prospects drilled by Core to date are mineralised with spodumene, including the Grants, Far West, BP33, Hills, Ahoy and Ahoy East prospects.
The high rate of drilling success on multiple prospects is significant for the potential scale of mineralisation at the Finniss Project, given the geographic spread of the prospects drilled so far (up to 10km distance from Grants) and the large number (likely to be tens if not hundreds) of pegmatite bodies of various size to be fully mapped and tested by Core.
Given the large aerial extent of the Company’s tenements, the high number of pegmatites in the Bynoe area, and the substantial proportion of mineralised pegmatites, Core expects to encounter a number of pegmatites with significant size and grade as it progresses its work programme across multiple targets within the field.
In the weeks ahead Core will report further Phase 2 RC drilling assay results from its Far West and Grants prospects, as well as results from diamond drilling at the Grants which are expected in March.

Ahoy and Ahoy East Prospects
Drilling at the Ahoy (two drill holes) and Ahoy East (three drill holes) prospects confirmed that both these prospects contain pegmatites that are mineralised with spodumene and host lithium grades above 1% Li2O (Figures 1 and 3).
The best results include a 12m spodumene intersection at 1.22% Li2O from 67m including 2m @ 1.94% Li2O at Ahoy in FRC074 (Figure 1 and Table 1).
A broad 39m intersection at Ahoy East comprised predominantly of pegmatite includes a number of narrower mineralised zones with grades up to 1.75% Li2O over 2m (Figure 1 and Table 1).
Far West Prospect
The drill results from the Far West prospect to date suggest that the Far West belt has the potential to deliver a series of smaller interconnected pegmatite bodies of spodumene bearing pegmatite over a distance of 1,000m that when combined, may represent a considerable volume of mineralised pegmatite.
New assays at Far West prospect include occasional higher lithium grades above 1.5% Li2O interspersed inconsistently within lower grade pegmatite intervals.
A significant intersection of high grade spodumene at Far West North was previously reported during the first drilling program at Far West North (45m @ 1.57 Li2O FRC030), however follow up drilling demonstrated that the pegmatite body was drilled oblique to dip and therefore the intersections were significantly larger than true widths. The lower grades intersected in drilling at Far West are interpreted to be due to weathering, and there is also evidence that some of the pegmatites are strongly zoned with quartz rich zones often diluting the overall grade.
The strike extent has not been closed off at Far West and internally this belt retains the potential for a number of high-grade pegmatite pods.
A summary of results to date from the Far West prospect are shown in Figure 2 and Table 1.
Core is still awaiting assays for 8 drillholes at Far West (Figures 2 and 3) which will be reported in due course.

Table 1. Significant Phase 2 RC results received to date from Far West North, Ahoy and Ahoy East prospects, Finniss Lithium Project NT.
Hills and Central Prospects
RC drillholes aimed at following up historic workings and soil sampling anomalies at Hills and Central resulted in narrow weathered pegmatites with minimal residual spodumene, the best intercept having previously been reported from FRC016 – 3m @ 0.55% Li2O. While the assay results for these two prospects were disappointing and no economic grades were encountered, they did demonstrate that the pegmatites are fertile for spodumene. These pegmatites potentially swell in size along strike, allowing a complete magmatic zonation.

Finniss Lithium Project Background
Core’s Finniss Lithium Project covers a large portion of the Bynoe Lithium-Tantalum-Tin Pegmatite field, which is a 20 kilometre wide belt of more than 90 tin and tantalum prospects and mines and lithium rich pegmatites which stretches over a distance of 75 kilometres south from Port Darwin (Figure 4).
Core’s drilling at Finniss has intersected high lithium grades and spodumene mineralisation within a number of pegmatites at Finniss. Core is pursuing a growing resource base at Finniss with aggressive drill programs continuing in 2017 in parallel with assessing early mine development options.
The Finniss Lithium Project has substantial infrastructure advantages being close to grid power, gas, and rail and services infrastructure and within short trucking distance by sealed road to the multi-user port facility at Darwin Port - Australia’s nearest port to Asia.

| Drill sample recovery Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. Sample recoveries are visually estimated and recorded for each metre. To date sample recoveries have averaged >95%. Contamination is monitored regularly. No issues have been encountered in this program. The cyclone and splitter are regularly cleaned, especially in wet intervals. Drill collars are sealed to prevent sample loss and holes are normally drilled dry to prevent poor recoveries and contamination caused by water ingress. Wet intervals are noted in case of unusual results. |

| 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). |

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 generally accepted as being the Two Sisters Granite to the west of the belt, and which probably underlies the entire area at depths of 5-10 km. Lithium mineralisation has been identified as occurring at Grants, BP33, Ahoy, Ahoy East, Hills and Far West |

| Data aggregation methods In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg 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. _ |
Mean grades have been calculated on a 0.4% Li2O lower cut-off grade with no upper cut-off grade applied. A 3m dilution is allowed. |

| Relationship between mineralisation widths and intercept 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. |
The true width is roughly 70% of the intercept width based on hole dip and the sub-vertical nature of the pegmatite body. |

| lengths If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole _length, true width not known’). _ |
|
| 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. All intersections have been reported and are considered representative. Refer table of drill hole collars in report. |
|
| 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 (eg 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. Remaining RC and Diamond drill samples have either been submitted or will soon be submitted to the laboratory for chemical assay. Assay results are expected during February and March 2017 |
