-
Approvals and financing discussions continuing and further offtake progressing, with the plan for the project to be development ready as market conditions improve in 2020.
1 Downhole intersections are not true widths owing to oblique nature of drill holes, and true with can only be assessed from sectional views. Refer to figures in announcement.
Advanced Australian lithium developer Core Lithium Ltd ( Core or Company ) (ASX: CXO) is pleased to announce a world-class spodumene pegmatite intersection at the BP33 Prospect within the Finniss Lithium Project, located near Darwin in the Northern Territory.
A world-class 119-metre continuous intersection of pegmatite was drilled by the Company as part of a recent deep RC and diamond drilling program at the BP33 Prospect.
Visual inspection of a 105m interval of the drill core and under UV light suggests that spodumene grades[2] . are in line with or better than the average grade 1.5% Li2O of the BP33 orebody (Figure 1).

Figure 1. Large light-green spodumene crystals in new pegmatite drill core from BP33.
2 Visual estimations of spodumene grade using UV is at best semi-quantitative and only assay results can be used to provide accurate grades.
Of note are the very coarse spodumene crystals of the BP33 pegmatite (Figure 1), which are typical of the spodumene pegmatites within the Finniss Lithium Project. The coarse crystalline nature enables the high recovery of lithium by simple, gravity dense media separation ( DMS ). Effective DMS separation translates into significantly lower capex, lower processing costs and low start-up risk.
The outstanding drill result indicates that the primary pegmatite body at BP33 extends with an ~40m true width for at least a further 100m vertically from previous drilling on that section and remains open at 400m vertical depth (refer Figure 2 and Figure 3).
All the holes completed during the recent RC and diamond drilling program intersected spodumene mineralised pegmatite outside of the current BP33 Mineral Resource and are therefore expected to substantially expand the defined Mineral Resource at BP33.
Assay results from the recently completed RC and diamond core drilling programs at BP33 are expected in January and in combination with previously recently released RC drilling results will be used to upgrade BP33 shortly thereafter.

Mining Studies highlight opportunities for underground mining at BP33 and Carlton
Early mining studies at BP33, and also Carlton, have highlighted important opportunities to increase mining efficiency and to substantially extend mine life and will be applied to the upcoming Mineral Resource expansion updates over coming months.
These opportunities include the potential to substantially increase Ore Reserves and mine life through the addition of cost-efficient underground mining of the wide, near vertical pegmatite orebodies that continue at depth at BP33 and Carlton, subsequent to developing Grants as a simple open-cut mining operation.
The new mining studies and updated feasibility study are expected to be completed in H1 2020 following the updated Mineral Resource estimate.
Approvals process nearly finalised
Core has successfully completed the NTEPA assessment process, which paves the way for Project’s Mining Management Plan ( MMP ) at Grants. Core is currently working with the NT Department of Primary Industry and Resources ( NTDPIR ) to secure final approval to enable mining and construction of the processing facility at Grants.
Core has provided all information requested by the NTDPIR, and although the feedback from NTDPIR has been positive and reasonable, the timeline to complete this final approval step is taking longer than expected. Core is in regular communication at multiple levels within the NTDPIR to ensure approval once due process is complete.
Market commentary
The lithium market has suffered from spodumene over supply during 2019. However, medium- and longer-term lithium demand is expected to exceed supply of lithium for lithium batteries to support global growth in electric vehicle and renewable energy storage.
The Company is progressing with the approvals process and progressing discussions with financiers and lithium customers to enable the project to be Final Investment Decision ready as the market recovers, expected to be during 2020. We are well placed to be Australia’s next lithium producer and the first shovel-ready lithium infrastructure project in the Northern Territory.
Substantial value enhancing continues
The DFS clearly indicated the substantial upside potential for shareholders from increasing the mine life at Finniss.
As such, we have been drilling and undertaking resource and mining studies at Grants, BP33, Carlton, Lees, Booths and Hang Gong, all aimed at potentially increasing Mineral Resources and Ore Reserves.
The outstanding new drill results combined with recent mining studies for Carlton and BP33 indicate that the wide, near vertical pegmatite bodies are potentially amenable to efficient underground mining methods, along with significant potential identified to materially increase the Finniss mine life.
Core’s Managing Director, Stephen Biggins, commented:
“ Core’s latest world-class spodumene pegmatite intersection at BP33 highlights the significant upside potential for the Finniss Lithium Project.
“Core are focused over coming months on increasing value for shareholders by growing Mineral Resources and increasing the mine-life of the Project.
“We are confident in having the Project shovel-ready in early 2020, so that we are wellpositioned to be Australia’s next lithium Producer as market conditions improve.”
About Core
Core is well positioned to be Australia’s next Lithium Producer, developing one of Australia’s most capital efficient and lowest cost spodumene lithium projects located in close proximity to Darwin Port.
Core’s 2019 DFS highlights production of 175,000tpa of high-quality lithium concentrate at a C1 Opex of US$300/t and US$50M Capex through simple and efficient DMS (gravity) processing of some of Australia’s highest-grade lithium resources.
Core is currently working toward increasing resources, reserves and mine-life ahead of project construction and lithium production, subject to financing and regulatory approvals.
The Finniss Lithium Project has arguably the best supporting infrastructure and logistics chain to Asia of any Australian lithium project. The Finniss Lithium Project is within 25km of port, power station, gas, rail and 1 hour by sealed road to workforce accommodated in Darwin and importantly to Darwin Port - Australia’s nearest port to Asia.
Core has established an offtake and prepayment agreement and is also in the process of negotiating further agreements with some of Asia’s largest lithium consumers and producers.

Commentary
-
Sampling • Nature and quality of sampling (e.g. cut channels, random chips, or techniques 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.
-
Reverse circulation (RC) and diamond core (DDH) drill techniques have been employed for the Core Lithium Ltd (“Core” or “CXO”) at BP33, during late October to early December 2019. A list of the hole IDs and positions can be found in the “Drill hole information” section below. Hole NRCD003 consists of a RC precollar to 192m and a DDH tail to EOH.
-
RC drill spoils over all programs were collected into two sub-samples:
o1 metre split sample, homogenized and cone split at the cyclone into 12x18 inch calico bags. Weighing 2-5 kg, or 15% of the original sample. -
20-40 kg primary sample, which for CXO’s drilling was collected in 600x900mm green plastic bags and retained until assays had been returned and deemed reliable for reporting purposes.
-
RC sampling of pegmatite for CXO’s assays was done on a 1 metre basis. 1msampling continued into the barren wall-zone of the pegmatite and then a 3m composite was collected from the immediately surrounding barren phyllite host rock.
-
Drill core was collected directly into trays, marked up by metre marks and secured as the drilling progressed. Geological logging and sample interval selection took place soon after.
-
DDH Core was transported to a local core preparation facility and cut firstly into half longitudinally along a consistent line between 0.3m and 1m in length, ensuring no bias in the cutting plane.
-
DDH sampling of pegmatite for assays is done over the sub-1m intervals described above. 1m-sampling continued into the barren phyllite host rock.
-
• RC Drilling was carried out by Bullion Drilling (Barossa Valley, SA; Schram 685 RC with 5.6-inch (143mm) face-sampling bit).

Drill sample • Method of recording and assessing core and chip sample recoveries recovery 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.
-
RC drill recoveries were visually estimated from volume of sample recovered. The majority of sample recoveries reported were dry and above 90% of expected.
-
RC samples were visually checked for recovery, moisture and contamination and notes made in the logs.
-
The rigs splitter was emptied between 1m samples by hammering the cyclone bin with a mallet. The set-up of the cyclone varied between rigs, but a gate mechanism was used to prevent inter-mingling between metre intervals. The cyclone and splitter were also regularly cleaned by opening the doors, visually checking, and if build-up of material was noted, the equipment cleaned with either compressed air or high-pressure water. This process was in all cases undertaken when the drilling first penetrated the pegmatite mineralization, to ensure no host rock contamination took place.
-
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.
-
DDH core recoveries were measured using conventional procedures utilising the driller’s markers and estimates of core loss, followed by mark up and measuring of recovered core by the geologist or geotechnician.

The history of mining in the Bynoe 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.
-
By 1909 activity was limited to Leviathan and Bells Mona mines in the area with little activity in the period 1907 to 1909.
-
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.

| Geology • Deposit type, geological setting and style of mineralisation. • The tenements listed above cover the northern and central 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 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 historically as occurring at Bilato’s (Picketts) and Saffums 1 (both amblygonite) but more recently LTR and CXO have identified spodumene at numerous other prospects, including Grants, BP33, Booths, Lees, Hang Gong, Ah Hoy, Far West Central and Sandras. |

| Relationship between mineralisation 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’). • All holes have been drilled at angles of between 68 - 73° and “lifted” by up to 10 degrees at target depth. The pegmatite dips steeply to the east and therefore the western-collared drillholes are oblique in a dip sense. • Hole were drilled approximately perpendicular to the strike of the pegmatites as mapped (refer to Table above for azi and dip data). • Some holes deviated in azimuth and therefore are marginally oblique in a strike sense. • Based on rough assessment of drill sections, true width represents about 35-70% of the intercept width,as outlined in the drillhole table. |
