ASX ANNOUNCEMENT
ASX: CXO
23[rd] August 2017
Large-scale Pegmatites Intersected in First RC Drilling at Zola, and Drilling to Re-Commence in Early September
HIGHLIGHTS
-
Broad drill intersections up to 70m wide of pegmatite encountered in first RC drilling at the Zola Prospect in the NT
-
Drilling confirms the central outcropping “core zone” of the pegmatite swarm at Zola is at least 1,000m long and over 400m wide
-
Drilling indicates a series of individual pegmatite bodies up 50m true width and hundreds of metres long
-
Economic lithium grades have not been intersected to date at Zola, however, Core is encouraged by the enrichment of lithium and the scale potential confirmed by first phase of drilling
-
Recent lithium in soils and magnetics have highlighted additional pegmatite targets adjacent to core zone at Zola
-
Second phase of shallow drilling to commence in September to test potential for higher grades in more fractionated pegmatites around the expanded Zola swarm
-
The Company is well funded and will continue to aggressively explore and advance its high-grade lithium discoveries
Core Exploration Ltd (ASX: CXO) (“Core” or the “Company”) is pleased to announce that the Company’s first RC drilling program at Zola has encountered broad intersections of pegmatite anomalous in lithium. Results to date confirm the large-scale of the Zola Pegmatite Swarm within the Finniss Lithium Project near Darwin in the NT (“Finniss”).
Core’s recent drilling has confirmed that the central outcropping “core zone” of the Zola Pegmatite Swarm covers a large area more than 1,000m long and over 400m wide representing a significant volume of pegmatite with elevated lithium contents.

Core is encouraged by the large scale and lithium fertility of the pegmatites intersected in initial drilling at Zola, and the Company’s immediate plan is to RC drill test the additional mapped pegmatites on the fringe of the first-pass drilling area.
The thickness of pegmatite bodies is very attractive, with down-hole intersections of at least 70m ending in pegmatite (Figures 1-3). These cross-sections below typify the interpreted pegmatite geometry at Zola.

Figure 1: Cross section 8591000N of pegmatites intersected in drilling, Zola Prospect.
This first round of RC drilling of the core of the Zola Pegmatite Swarm has shown that the pegmatites intersected are elevated in lithium (up to 0.1% Li2O) and the magmatic system is fertile. However, no economic grades of lithium were intersected in the first RC program.
Recent magnetics and soil data suggest that there are outlying pegmatite bodies to the east and west of Zola under cover of laterite, which if the system is outwardly-zoned, have the potential to be mineralised with lithium.
RAB drilling is expected to recommence at Zola in early September to define the surface expression of these outer pegmatite bodies followed by deeper RC drilling to test the lithium grade of the fresh pegmatite material.

- Zola Prospect Phase 1 RC Drilling
The initial RC program at Zola comprised 9 RC holes (ZRC001 to ZRC009) to test the centre of the Zola pegmatite swarm.
The drill sections within the central part of Zola support a series of pegmatites of substantial width (30m to 50m true thickness), within a 400m wide zone over more than 1,000m long (Table 1).
The pegmatite swarm is interpreted to dip at overall 60-70 degrees to the east and strike roughly north-south (Figures 1 and 2).

Figure 2: Cross section 8590600N of pegmatites intersected in drilling, Zola Prospect
Many of the RC holes drilled at Zola intersected pegmatite that included a range of fluorescent minerals similar to those seen at other pegmatites mineralised with spodumene elsewhere in the Bynoe pegmatite field. However, in the context of recent assays, the proportion of fluorescent minerals being spodumene is low in the pegmatite intersected to date.
Typically producing pegmatite fields are zoned, often with quite dramatically differentiation over short distances, so Core believes that the drilling results to date, which only tested the central core of the swarm represent only a partial test of the Zola pegmatite system

Core’s focus in the Zola area will now move to test the peripheral pegmatite bodies that have the potential for a level of pegmatite fractionation that may host higher lithium grades than the central core zone at Zola (Figure 3).
Recent soil data has added several new pegmatite targets to test, surrounding the core of Zola. These coincident soil and magnetic anomalies are thought to relate to concealed pegmatites peripheral to the main prospect.

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. |

| 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. |
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. |

Whether sample sizes are appropriate to the grain size of the material being sampled. |
RC samples referred to in this report have been composited from the green bags via a spear. Typically, this composite is 5m length, but locally it is narrower where the geology is complicated. The composite weighs approximately 3-5 kg. Any high-grade intervals are resampled on a 1m-basis utilising the cyclone split. This can only be carried out once the assays have returned for the composites. AC samples are collected exclusively via a spear and weight 3-5 kg. No AC assay data is reported here, as it weathered and therefore does not provide any direct indicator of the grade of fresh material at depth. It is useful only for mapping and confirming the presence of pegmatite. Most samples are dry, but wet or damp samples are recorded.

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 GreenbushesTinandTantalite (andlaterspodumene) |

| 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. 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 publishedin 2004(NTGSReport16,Frater 2004). |

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.

| should be clearly stated. | |||
| Relationship between minrliti |
These relationships are particularly important in the reporting of Exploration Results. |
The true width varies significantly with respect to the intercept width due to the varied pegmatite orientation in this regional exploration program. Typically, not a lot is known about the pegmatite geometry prior to drilling. Unless multiple holes are drilled into any given body, estimates of pegmatite dip rely heavily on surface expression and assumptions about drillhole pierce points in 3D space. On average for a sub-vertical pegmatite body, however, Core estimates that the true width is roughly 70% of the intercept width based on hole dip starting at 55 degrees. |
