Li3 | Warriedar Exploration Update - Large gold anomaly identified
Lithium Consolidated Ltd (Li3) is pleased to announce that anomalous gold and indicator elements
have been detected over large areas at the highly prospective Warriedar West Zone which forms part of
the Company’s 100% owned Warriedar Project in the Murchison region of Western Australia. Initial
analysis of these results confirm the company’s view that it is prospective for large scale mineralised
systems.
Summary

-
Large 5km x 2km gold and gold pathfinder element anomaly identified
Adjacent to gold mineralisation and artisanal workings
Assays received for 232 samples from reconnaissance program
Further sampling planned to establish drill targets and extend identified zones
Activities
In February 2020 Li3 conducted a reconnaissance geochemical and geological mapping program at the
company’s Warriedar West Prospect within the Murchison region of Western Australia. The program was
undertaken by multiple teams with sample spacing for the initial work on a 500m offset grid pattern.
Sampling was done in conjunction with geological mapping utilising sophisticated digital mapping
systems. Parts of the planned program were not completed due to logistical challenges associated with
the outbreak of the COVID-19 virus. Also, areas of deeper than expected transported cover were
encountered, which will require alternative sampling techniques such as Rotary Air Blast (RAB) drilling.

Project Geology
The Warriedar West prospect is a zone of porphyritic monzonite1 with a number of known sources of gold
mineralization including in-situ primary quartz veins, laterites and alluvials. These have been exploited
in modern times by artisanal means.
The aim of the recent surface sampling program at the Warriedar West prospect was to obtain further
insight into the geology and source of the mineralization through multi-element geochemistry. Some
highlights of this work are shown below:
Figure 2: Sample points - Gold (ppb)
The geological model indicated by the evidence compiled by the Li3 technical team places the
mineralization in that of an Intrusion Related Gold System (IRGS). Due to the relatively new classification
IRGS are not widely explored for, though this is changing. Many contemporary examples of this kind of
deposit include the Timbarra4 deposit in northern New South Wales (0.5Moz Au), Kidston5 in northern
Queensland (5.3Moz Au) and the high profile Northern Star Resources Pogo Mine6 (10Moz Au) in Alaska.
These types of deposits are often hosted within small plutons like the host rock at Warriedar (the
Walganna Suite) and are typified by an array of sheeted quartz veins with associated argillic and sericitic
alteration halos 2.
Another definitive feature of many IRG systems is the affinity to certain trace elements such as Arsenic,
Antimony and Tungsten3. Several multi-square-kilometer anomalous areas are visible at Warriedar for a
number of these indicator elements as shown in Figures 3 and 4.

The results above are in addition to similar work conducted at the Meleya Prospect (refer ASX release
dated 24 March 2020) which identified base metal and gold anomalism within a newly identified geological
zone highly prospective for VMS and Archaean Gold.

As announced on 06 April 2020, in response to the COVID-19 outbreak, field work at the company’s
projects are temporarily suspended and cost mitigation actions have been implemented.
The Company is monitoring the situation closely and is cooperating with the relevant regulatory authorities
with a view to restarting work onsite at the earliest possible opportunity.
The Board of the Company has authorised the release of this announcement to the market.

Further work
● In reporting Exploration Results, weighting averaging techniques,
maximum and/or minimum grade truncations (eg 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.
●
Not applicable.
● 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 (eg ‘down hole length, true
width not known’).
●
Not applicable.
● 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.
● 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.
● 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.
● The nature and scale of planned further work (eg tests for lateral
extensions or depth extensions or large-scale step-out drilling).

including the main geological interpretations and future drilling areas,
