ASX: CXO Announcement
15 August 2022
Core provides exploration activities update
Highlights
-
+40,000m RC drilling program underway
-
Pipeline of existing and new targets at Finniss to be tested
-
Two successful grants awarded under the Resourcing the NT Initiative
-
High grade lithium rock chip results received from AnningieBarrow Creek Project
Australia's next lithium producer, Core Lithium Ltd ( Core or Company ) (ASX: CXO ), is pleased to provide an update on its exploration activities in the Northern Territory.
Finniss Lithium Project
Diamond Drilling
As previously announced, diamond drilling is well underway at BP33, with a focus on exploring the depth and strike extensions of the main pegmatite intrusions.
Diamond drilling at BP33 will be followed up with extensional exploration and resource definition programs at Carlton, Hang Gong, Lees and Sandras. These programs are designed to further build on the Mineral Resource Estimates (CXO ASX Announcement 12 July 2022).
RC Drilling
Core has commenced a +40,000m RC drill program, which will be split between greenfields and brownfields target areas. A large RC rig has been mobilised to test some of the deeper targets.
The program will be focused on following up prospects where excellent exploration results were reported from 2021 drilling, including Bilatos, Penfolds, Centurion and Talmina West, as well as many new conceptual targets.
Results of both RC and diamond drilling programs will provide a continuous flow of new results during the year, with the possibility of new prospects and new mineral resources being defined.

NT Co-Funding Grants
The Company is pleased to advise that Grants NT has approved two separate applications for co-funding in Round 15 of the Northern Territory Geophysics and Drilling Collaborations program.
The approved programs are:
-
Ambient Noise Tomography survey, which is now planned at the Shoobridge Lithium Project, EL31407, near Pine Creek NT. Seismic velocity data will be acquired to identify pegmatite drill targets. This work is planned to commence in September 2022 and the grant amounts to $100,000.
-
A single deep diamond drill hole targeting the down plunge extension to the currently defined Mineral Resource at the Sandras Lithium Deposit. The current total Mineral Resource at Sandras is 1.44Mt @ 1.01% Li2O (refer ASX Announcement 12 July 2022). Sandras has been modelled to a vertical depth of approximately 250m below surface. The planned hole has been designed to intersect the projected down plunge extension to the mineralisation at approximately 450m below surface, approximately 200m deeper than existing RC drilling. This grant also amounts to $100,000.
Anningie-Barrow Creek (ABC) Project
Since 2018, Core has assembled a strong lease position covering approximately 2,805km[2] in the Barrow Creek Pegmatite Field in the NT. The ABC Project is considered an early-stage lookalike to the Company’s high-grade discoveries at the Finniss Lithium Project, with a long history of tin and tantalum production around Barrow Creek and Anningie. The ABC Project is favourably situated alongside the railway that links to the Darwin Port.
Company geologists undertook a short familiarisation trip to the Bismark Prospect, located within the Anningie Tin Field, and assayed 13 rock samples. Six of these returned greater than 1% Li2O, with a maximum of 4.78% Li2O (Figures 2 and 3). Unlike the Finniss Lithium Project, spodumene occurs at the surface. These results confirm the results of previous explorers and highlight the latent potential of this project.
The Company is planning to recommence work on the ABC Project later this year.

Finniss Gold Project Update
While Core is firmly focused on delivering Australia’s next lithium project, the Company has also undertaken exploration of existing gold mineralisation within the Finniss Lithium Project.
Gold-focused activities completed since the start of 2021 have included increasing the number of samples in the Finniss Project’s geochemical database by over 25,600 through the sampling of new sites together with assaying retained analytical pulps from historical lithium-focussed surface samples for gold.
Interpretation of the results suggest that the gold mineralisation at Finniss is of a style closely comparable with that seen at gold deposits in the Pine Creek Orogen (“PCO”), a gold district with past production and current reserves totalling in excess of 18 million ounces. The deposits in the PCO and at Finniss are turbidite-hosted epigenetic, fold-controlled deposits, with gold hosted in quartz lode structures and having associated arsenopyrite, pyrite, and bismuth-bearing minerals.
Core’s exploration has delineated more than 40 surficial gold geochemical anomalies on the Project tenements. Significant regions of the tenements remain to be geochemically sampled and the discovery of anomalies additional to those already delineated is a possibility.
Drilling programs have targeted five of the anomalies, with 429 RAB holes (7,703m), 21 RC (2,353m) holes and 3 diamond holes (722.7m) drilled. Strongly anomalous gold is present at shallow depths in all five of the targets drill tested, including at Golden Boulder where an auriferous, steeply east dipping quartz lode has been defined in drilling (Figure 4). A listing of drill intersections over 1g/t Au is shown in Table 1. Gold anomalous zones exhibit quartz veins and sulphides or their weathered equivalent, with arsenopyrite particularly prevalent.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
Criteria JORC Code Explanation Commentary

Criteria JORC Code Explanation
-
Sampling • Nature and quality of sampling (e.g. cut channels, random chips, techniques 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.
-
Rotary Air Blast (RAB), Reverse circulation (RC) and diamond core (DDH) drill techniques have been employed for the Core Lithium Ltd (“Core” or “CXO”) drilling.
-
RC drill spoils over all programs were collected into two sub-samples:
- 1 metre split sample, homogenized and cone split at the cyclone into calico bags. Weighing 2-5 kg.
-
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
- A primary sample, was collected in green plastic bags and retained until assays had been returned and deemed reliable for reporting purposes.
-
RC sampling was done on a 1 metre basis.
-
Aspects of the determination of mineralisation that are Material to the Public Report.
-
Drill core was collected directly into trays, marked up by metre marks and secured as the drilling progressed.
-
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.
-
DDH Core was transported to a local core preparation facility where geological logging and sample interval selection took place. Core was cut into half longitudinally along a consistent line generally between 0.3m and 1m in length, ensuring no bias in the cutting plane.
-
RAB drill spoils over the program were collected in green plastic bag for each metre and retained until assays had been returned and deemed reliable for reporting purposes.
-
RAB spoils were typically speared to collect a ub-sample into a calico bag for intervals ranging from single metre to 6m composites.
-
Where composite RAB samples returned anomalous results, 1m splits of the same size and in the same manner were collected for assay.
-
Rock chips samples were collected from in-situ outcrops using a hammer to
collect approximately 1kg of sample.

Measures taken to maximise sample recovery and ensure representative nature of the samples.
-
RC and RAB samples were visually checked for recovery, moisture and contamination and notes made in the logs.
-
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.
-
The RC rigs splitter was emptied between 1m samples. A gate mechanism on the cyclone 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.
-
The RAB rigs cyclone was emptied between 1m samples by hammering the cyclone bin with a mallet. The cyclone was 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.
-
RC 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.
-
DDH core recovery is >95% in the quartz vein zones and in fresh host-rock.

-
RC and RAB chips are stored in plastic chip trays.
-
DDH core is stored in plastic core trays.
-
• All holes were logged in full.
-
RC chip trays and DDH core trays are photographed and stored on the CXO server.
-
The majority of the mineralised samples were collected dry, as noted in the drill logs and database.
-
RC field sample preparation involved collection of samples from the cone splitter on the drill rig into a calico bag for dispatch to the laboratory.
-
The sample sizes are considered more than adequate to ensure that there are no particle size effects relating to the grain size of the mineralisation.
-
A field duplicate sample regime is used to monitor sampling methodology and homogeneity of RC and RAB drilling at Finniss. The typical procedure was to collect Duplicates via a spear of the green RC bag, having collected the Original in a calico bag.
-
The duplicates cover a wide range of values.
-
Results of duplicate analysis show an acceptable degree of correlation.
-
Sample preparation for RC samples occured at North Australian Laboratories (“NAL”), Pine Creek, NT.
-
A 1-2 kg riffle-split of RC Samples are prepared by pulverising to 95% passing - 100 um. RC samples do not require any crushing, as they are largely pulp already.
-
Half Drill Core sample intervals were constrained by geology, alteration or structural boundaries, intervals varied between a minimum of 0.3 metres to a maximum of 1 m. The core is cut along a regular Ori line to ensure no sampling bias.
-
Field and lab standards together with blanks were used routinely.
-
The purpose of the RAB sampling is to act only as an exploration guide or vector towards mineralisation, and as an open hole technique has lower sample integrity than the RC and diamond drilling. Nevertheless, the large
sample size is considered adequate to minimise particle size effects relating to the grain size of the mineralisation. Duplicates were collected into a calico bag via a spear of the primary green bag, having first collected the original from the same primary bag. No splitters were used for RAB.
-
Quality of assay • The nature, quality and appropriateness of the assaying and data and laboratory procedures used and whether the technique is laboratory tests considered partial or total.
-
For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.
-
Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.
-
Sample analysis for RAB, RC and routine DDH samples occurred at North Australian Laboratories, Pine Creek, NT.
-
Samples were dried then pulverised to 85% passing 75 microns or better using a Keegormill. This is believed to be the most appropriate method for nuggety gold samples
-
For the multi-element analysis, A sub-sample of the pulp is digested in a standard 4 acid mixture and analysed via ICP-MS and ICP-OES methods for the following elements: Li, Fe, K, P, S, Cu, Pb, Zn, Ag, Co, Ni, Mn, As, Mo, Se, Te, Sb, Bi, Sn, Ta, Nb, U, W and Th.
-
A 3000 ppm Li trigger was set to process that sample via a fusion method. The fusion method was - a 0.3 g sub-sample is fused with 1g of Sodium Peroxide Fusion flux and then digested in 10% hydrochloric acid. ICP-OES is used for the following elements: Li, P and Fe. The lower and upper detection range for Li by this method are 10 ppm and 20,000 ppm respectively.
-
Gold analysis has largely been carried out via Fire Assay AAS-finish for a 40-50g aliquot of the bulk RAB samples processed via the Keegormill route. This “ore grade” methodology has a detection limit of 10 ppb.
-
A barren flush is inserted between samples at the laboratory.
-
NAL has a regime of 1 in 8 control subsamples.
-
NAL utilise standard internal quality control measures including the use of Certified Lithium and Gold Standards and duplicates/repeats.
-
Approximate CXO-implemented quality control procedures include:
oOne in 20 certified Lithium or gold ore standards-
One in 20 duplicates were used for the RC drilling program.
-
oOne in 20 blanks were inserted for this drilling.
-
-
The duplicate analysis for gold shows that there is considerable variability between the gold grade of samples which likely relates to the nuggety nature of gold in some samples. No screen-fire assaying has been undertaken, but is
recommended for further work on gold targets.

FINNISS GOLD - • The history of gold mining in the broader Pine Creek Orogen dates back as far as the 1880s. It has had a varied history since. In respect to the Finniss area, there has been very minimal gold exploration or mining – it has been almost exclusively a tin-tantalum province. The only exception appears to be Golden Boulder, which was mined via shallow shafts and pits in the early 1990s producing 18-22 kg of gold. No other historic production or exploration is known. The earliest documented “modern” gold exploration within the Finniss Project was in the mid-1990s by Greenbushes Ltd (drilling at Golden Boulder). This was followed by surface exploration by Haddington Resources Ltd (mid 2000s), then Liontown Resources Ltd (2016-2017) and lastly Core Lithium Ltd (2016 to present). BARROW CREEK – ANNINGIE |
• There have been multiple, sporadic but intensive periods of prospecting, exploration and small scale mining within the Barrow Creek -Anningie Project area since the 1940s. All known previous work has focused on tungsten, tin and tantalum with no systematic assaying for lithium. • All previous work has focussed on either alluvial/eluvial material or the upper, weathered portion of the bedrock which would be suitable for free digging. • The geological map provided in this report at Anningie was originally done by Todd River Resources, who reported on the Bismark prospect (ASX: TRT 21[st] December 2017) and confirmed the presence of spodumene as the main lithium bearing phase FINNISS -

| Data 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 clearlystated. |
||
| 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’). |
||
| 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. |
||
| 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 reportingof Exploration Results. |
||
| 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. |
||
| 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). |
