DRILLING CONTINUES TO HIT THICK ZONES OF SPODUMENEBEARING PEGMATITE AT SEYMOUR LAKE, CANADA

Latest drilling continues to expand the scale and potential of the Seymour Lake Lithium Project

HIGHLIGHTS:

• Phase 2 resource drilling program progressing well with a further five diamond holes now completed.

• Multiple shallow and deeper spodumene-bearing pegmatites intersected in latest holes, including thick mineralised zones with a combined down-hole width of up to 21m.

• Drilling is confirming the interpreted mineralised extensions, providing a greater level of geological understanding and confidence while also steadily increasing the overall scale of the project.

• Drilling continues to confirm the presence of multiple pegmatite zones at the North Aubry prospect – with the mineralisation remaining open to the east, west and down-dip.

• Phase 2 results to underpin a maiden JORC 2012 Mineral Resource.

Diversified minerals explorer and developer Ardiden Limited (ASX: ADV) is pleased to advise that it continues to make excellent progress with the ongoing Phase 2 resource delineation diamond drilling program at its Seymour Lake Lithium Project in Ontario, Canada, with the latest drill-holes intersecting multiple spodumene-bearing pegmatites from close to surface.

NORTH AUBRY PROSPECT DRILLING

The latest five drill-holes (SL-17-10 to SL-17-13, SL-17-24) have now been completed and logged by the geological team. This batch of drill holes has again intersected multiple spodumene-bearing pegmatites both close to surface and at depth over various widths, confirming the presence of multiple pegmatite layers, including:

• Hole SL-17-13, which intersected a total of 21.04m (including 16.1m zone from 95m down-hole) of spodumene-bearing sills over a total down-hole width of 121m; and

• Hole SL-17-12, which intersected a total of 11.95m of spodumene bearing sills over a total down-hole width of approximately 110m (refer to Table 1 below).

The drilling has continued to validate the known primary mineralised zones, further defining the boundaries of the main outcropping area and extensions of the secondary spodumene-bearing pegmatites at the project. Once the drill core has been logged, cut and prepared, the drill samples will be sent to Activation Laboratories in Thunder Bay for assay.

Ardiden notes although the pegmatites at Seymour Lake can be somewhat difficult to model and predict due to the erratic nature of the formation paths, confirmation of the interpreted extensions of the spodumene-bearing pegmatites and the verification of multiple pegmatite layers in the latest drilling provides the Company with a greater level of understanding and confidence in the project, while also steadily expanding the overall scale of the project and its future resource potential.

The first part of the current drilling program was designed with close-spaced drilling to ensure a high level of confidence in the data to support initial maiden JORC 2012 Mineral Resource.

Once a sufficient number of drill results and geological data have been obtained during this drill program, it will provide the Company a solid basis of understanding about the multiple spodumene-bearing mineralisation zones contained in the central portion of the North Aubry prospect – underpinning an initial JORC 2012 Mineral Resource for Seymour Lake.

Once it has established the basis for an initial JORC 2012 Mineral Resource in the central mineralised zone at North Aubry, Ardiden will conduct wider-spaced drilling in order to confirm the extensions of the spodumene mineralised zones which can be incorporated in future resource estimates.

As previously advised, the current diamond drilling program is designed to target the immediate project area around the North Aubry prospect, which is located within an extensive 5km long pegmatite zone identified during the mapping and sampling campaign completed in 2016.

Figure 1. Overview showing the current drill hole locations (Blue) and the pegmatite exposures at North Aubry prospect, with interpreted extensions.

These drill holes have continued to verify the western and northern extension of the multiple pegmatite mineralised sills. The continued intersection of multiple high quality spodumene-bearing pegmatite reinforces the potential to establish a maiden JORC 2012 Mineral Resource estimate for the Seymour Lake Project.

The identification of pegmatites either at or close to surface represents a strategic advantage for the project, potentially allowing easier access to high-quality mineralisation in a future mining scenario.

The proximity of the pegmatites to surface is likely to reduce the required pre-strip, resulting in lower extraction costs and therefore improved project economics.

About Ardiden Ltd

Ardiden Limited (ASX: ADV) is an emerging international strategic metals company which is focused on the exploration, evaluation and development of multiple projects located in the established mining jurisdiction of Ontario, Canada.

The Seymour Lake Lithium Project comprises 7,019 Ha of mining claims and has over 4,000m of historic drilling. Mineralisation is hosted in extensive outcropping spodumene-bearing pegmatite structures with widths up to 26.13m and grades of up to 6.0% Li2O. These high-grade pegmatite structures have been defined over a 5km strike length.

The 100%-owned Root Lake Lithium Project is located in Ontario, Canada. The project comprises 1,013 Ha of mining claims and has over 10,000m of historic drilling. Mineralisation is hosted in extensive outcropping spodumene-bearing pegmatite structures with widths up to 19m and grades of up to 5.10% Li2O. In addition, tantalum grades of up to 380 ppm were intersected.

The 100%-owned Root Bay lithium project is strategically located approximately 5km to the east of the recently acquired Root Lake Lithium Project and consists of three claim areas, totalling 720 hectares. The project was staked by Ardiden as part of its regional exploration focus in and around the Root Bay spodumene-bearing pegmatite.

Initial observations of the exposed pegmatite are characterized by coarse white albite, grey quartz and pale grey-green spodumene crystals up to 10cm long.

The 100%-owned Manitouwadge Flake Graphite Project covers an area 5,300 Ha and has a 20km strike length of EM anomalies with graphite prospectivity. Previous preliminary metallurgical testwork indicated that up to 80% of the graphite at Manitouwadge is high value jumbo or large flake graphite. Testwork also indicated that simple, gravity and flotation beneficiation can produce graphite purity levels of up to 96.8% for jumbo flake and 96.8% for large flake. With the proven caustic bake process, ultra-high purity (>99.95%) graphite can be produced. The graphite can also be processed into high value expandable graphite, high quality graphene and graphene oxide.

All projects located in an established mining province, with good access to infrastructure (road, rail, power, phone and port facilitates) and local contractors and suppliers.

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

Criteria	JORC Code explanation		Commentary
Sampling techniques	• Nature and quality of sampling (e.g. cut channels, random chips, 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. • 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 30g 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.	• Diamond Drill Core was cut in half split using a core saw. along a plane perpendicular to the foliation within the host rock gneiss. • Bagging of the half core samples was supervised by a geologist to ensure there are no numbering mix-ups. • One tag from a triple tag book was inserted in the core tray in the position of the sample interval. • Standard sample intervals averaged 1 m. • Sampling continued through intervening barren rock (if less than 10m width) where multiple Spodumene Pegmatite zones were intersected • The sample preparation and assaying techniques are industry standard and appropriate for this type of mineralisation.
Drilling techniques	• Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).	• Diamond wireline core drilling. • The drill core size is CHD 76, core diameter is 43.5 millimetres • Drill holes were orientated using the Reflex ACT II RD core orientation tool
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.	• The sample interval of core was measured and recorded along with a description and incorporated in the completed drill logs. • Core within the mineralised zone tended to be uniform and competent so loss was minimal and samples represent the true nature of the mineralisation • No relationship between sample recovery and grade is evident.

Criteria	JORC Code explanation		Commentary
Logging	• Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length andpercentage of the relevant intersections logged.	• Samples represent half the core width, and are logged in detail to support appropriate Mineral Resource estimation at a later stage of exploration.
Sub-sampling techniques and sample preparation	• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second- half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled.	• Core is split in half using a core saw with the remaining half retained in the core tray. • Mineralisation is massive and relatively uniform so assay samples closely represent the in-situ material. • Samples were taken on an average of 1 meter intervals and were determined to be appropriate for the mineralised material being sampled
Quality of assay data and laboratory tests	• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is 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) andprecision have been established.	• All samples will be analysed by Actlabs in Thunder Bay, Ontario Canada a SCC (Standards Council of Canada) accredited laboratory. • The assay technique will be FUS-Na202 • Quality control procedures included the insertion of certified standards and blanks into the sample stream. • Results of the Heavy Liquid Separation tests are outlined in Table 3.
verification of sampling and assaying	• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data.	• Drill logs and sample information is documented and stored digitally in field laptop units and backed up on the Ardiden server.

Criteria	JORC Code explanation		Commentary
	• Quality and adequacy of topographic control.
Data spacing and distribution	• Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied.	• Core samples of the mineralised zone were taken at approximately 1 meter intervals and deemed appropriate to represent the in situ nature of the mineralization. • Further drilling and sampling will be required to adequately establish the geologic and grade continuity for any Mineral Resource and Ore Reserve estimationprocedure.
Orientation of data in relation to geological structure	• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.	Drill hole locations were designed to intercept the mineralised zone as close to true width as possible to avoid sampling bias.
Sample security	• The measures taken to ensure sample security.	• Samples were secured and delivered to the assay lab under chain of custody controls by the Caracle Creek Consulting group
Audits or reviews	• The results of any audits or reviews of sampling techniques and data.	• No audits or reviews of sampling techniques have been conducted

Criteria	JORC Code explanation	Commentary
Exploration done by other parties	• Acknowledgment and appraisal of exploration by other parties.	• Other parties have not appraised the exploration carried out to date
Geology	• Deposit type, geological setting and style of mineralisation.	• Seymour Lake area pegmatites have been classified as belonging to the Complex-type, Spodumene-subtype. Mineralization is dominated by spodumene (Li), with lesser tantalite(Ta) hosted in a series of variably steeplydipping pegmatite dykes and and sills.
Drill hole Information	• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.	• See Tables 1 and 2 and Figures 2 and 3 for the location of the drill collars and other dill hole information.
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 clearly stated.	• With the homogeneity of the mineralised material, sample intervals for the most part were kept at one metre intervals
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’).	• Mineralised zones were determined to be shallow dipping and drill holes were drilled at -60 degrees so that drilling orientation bias was minimised

Criteria JORC Code explanation	Criteria JORC Code explanation	Commentary
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 2 and 3 for the location of the drill hole collars
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.		• No comprehensive report has been completed to date to include the latest Ardiden 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.	• All meaningful and material data is reported
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). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.		• Refer to text within the report.
