ASX ANNOUNCEMENT

ASX: CXO

13[th] December 2016

AT FAR WEST PROSPECT

HIGHLIGHTS

  • High grade lithium assays and numerous pegmatite intersections from initial results of Phase 2 RC Drilling at the new Far West Prospect within Core’s Finniss Lithium Project

  • Thick intersections of high grade spodumene mineralisation in RC holes drilled at the Far West North Prospect, including:

  • 45m @ 1.57% Li2O from 62m (FRC030) including

    • 7m @ 2.28% Li2O from 66m; and

    • 8m @ 2.48% Li2O from 88m

  • 17m @ 1.12% Li2O from 62m (FRC028)

  • The Far West Prospect is located 500m from Core’s previous high grade spodumene discovery at Grants

  • Potential for considerable volume of mineralised pegmatite bodies at Far West over 1,000m of strike

  • Exploration and follow-up RC drilling are continuing at Finniss

  • Further drill assay results from the Phase 2 RC Program at Finniss are expected into early 2017

Core Exploration Ltd (ASX: CXO) (“Core” or the “Company”) is pleased to announce that high grade lithium assays have now been received from its Phase 2 RC program at the Far West North Prospect within the larger Finniss Lithium Project near Darwin in the NT (“Finniss”).

Far West is a new high grade lithium discovery and follows significant lithium discoveries at the Grants Prospect and BP33 made by Core’s Phase 1 drilling program.

Far West comprises a series of pegmatite bodies that have been intersected by drilling consistently over a 1,000m strike length between Far West North and Far West Central.

Core’s first drilling results indicate that Far West North and Far West Central have the potential to deliver a series of interconnected pegmatite bodies of spodumene bearing pegmatite that combined, may represent a considerable volume of mineralised pegmatite.

A thick zone of high grade spodumene has been intersected during the first drilling program at Far West North (45m @ 1.57 Li2O FRC030). Further drilling is required to better understand the dimensions and orientation of this zone with other intersections at Far West North typically ranging from 5-15m true width (Figures 1-3).

These first significant results from the Phase 2 RC program are set out below:

Table 1. Significant Lithium assay grades in RC drillholes at Far West Prospect, Finniss Lithium Project NT (0.4% Li2O lower cut-off grade with no upper cut-off grade applied, and maximum internal waste of 2.0 metres).

Similarly, several 50-60m thick intersections of pegmatite have also been intersected at Far West Central, assays have not yet been received from this drilling (Figures 1-3).

Assays from the remainder of the initial RC drilling program at Far West North and Far West Central are expected in coming weeks.

Next Steps

RC drill assays from Far West North, Far West Central, Grants and other prospects from Core’s current Phase 2 RC drilling are expected over coming weeks and into early 2017.

Access to the Finniss Project remains good, supported by the high quality sealed road network around the Project area near Darwin. Therefore, Core currently plans to continue drilling, mapping, sampling and other exploration programs at Finniss Lithium Project into early 2017, weather permitting.

Finniss Lithium Project Background

Core’s Finniss Lithium Project covers a large portion of the Bynoe Lithium-Tantalum-Tin Pegmatite field (Figure 4).

Core’s drilling at Finniss has intersected high lithium grades and spodumene mineralisation within a number of pegmatites at Finniss.

The Bynoe Field is a 15-20 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 and is one of the most prospective areas for lithium in the NT.

Core’s Finniss Lithium Project has substantial infrastructure advantages being close to grid power, gas, and rail and services infrastructure and within easy trucking distance by sealed road to the multi-user port facility at Darwin Port - Australia’s nearest port to Asia.

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

entered into a JV named the Bynoe Joint Venture with Barbara

and produced tin and tantalite from its Observation Hill
Treatment Plant between 1986 and 1988.
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.
