ASX ANNOUNCMENT

Auger sampling outlines Gold Target areas at Barlee Project
BARLEE PROJECT - ELs 77/2606, 57/1135, and ELA 77/2688 (Cullen 100%)
Cullen Resources Limited (“Cullen” or “the Company”) has received the assays for 579 auger samples collected on a 400 x 100m grid over a section of N - S trending stratigraphy within E2606. This ~7 x 4km target area has been interpreted from air magnetics data to include underexplored shear zones and numerous elongate and/or folded sections of greenstone in contact with granites (Figs.1 and 2), which Cullen considers has potential to host quartz gold lodes of the Penny-type.
This is the first systematic field test within the project area, that extends from 10 - 55 km SSE of the Penny Gold (previously “Penny West”) deposit and the Youanmi greenstone belt towards the NW tip of the Marda - Diemals greenstone belt (Fig.1).
Highlights
-
Cullen considers these first-pass auger sampling results to be highly encouraging, with three key target areas outlined for further investigation (Areas 1-3, Figs.3 -4)
-
Cullen is currently negotiating a heritage agreement to allow for access development and required clearances for further exploration which would likely include field mapping, follow-up sampling and first pass air core drilling.
Results Gridded images of all geochemical data, are shown in Fig.5.
-
Target Area 1 : Gold values of 2-10ppb form a coherent zone of interest overlying interpreted greenstone and coincident with an anomaly of Ag (to 110ppb) and elevated pathfinder elements - As, Bi, Mo, Pb, and Te;
-
Target Area 2: Elevated levels of As, Bi, Mo, Pb, and Te over ~2.5km in strike length, overly a zone of greenstones interpreted from air magnetics images;
-
Target Area 3: A single, notable value of 430ppb Ag along the southern boundary of the survey (Ag values are generally below detection, <10ppb), with a gold assay of 11ppb nearby – close to western granite-greenstone contact;

Exploration Update – March 2021
-
The distribution of Cu, Co, Zn and Ni values is similar and interpreted to reflect the trend of greenstones, but elevated pathfinder levels overlie only portions of these trends;
-
Galena is a characteristic sulphide associated with the Penny high-grade gold zone, hence a focus on the Pb assay distribution from this auger program; and,
-
The highest nickel and copper values overlie the most magnetic portions of interpreted greenstones and suggest ultramafics may occur locally.
Conclusions
The coherent anomaly of Au with Ag which is coincident with As, Bi, Au, Mo, Pb, and Te, is interpreted by Cullen to represent an overprint of felsic intrusives and/or hydrothermal alteration on greenstones (Target Area 1)
The second As, Bi, Au, Mo, Pb, and Te zone to the south-east , ~2.5 km in strike length, overlies greenstones cut by a major E-W fault, as interpreted from air magnetics images (Target Area 2)
The western Ag-Au anomaly (Target Area 3) is open to the south and may be partially obscured to the north due to the presence of a channel where auger sampling to ~1m depth may not have been effective.
In Cullen’s opinion, these compiled geochemical, geophysical and regolith data have identified key target areas with gold lode potential for further investigation.

Forward Plans
Cullen is currently negotiating a heritage agreement to allow for the development of access into the area for further exploration. In the first instance, the Company plans to seek clearance for air core drilling traverses as planned along existing fence lines. Such work to be undertaken in conjunction with field mapping and follow-up sampling within the targets areas to prepare for later drill testing.

ATTRIBUTION: Competent Person Statement
The information in this report that relates to exploration activities is based on information compiled by Dr. Chris Ringrose, Managing Director, Cullen Resources Limited who is a Member of the Australasian Institute of Mining and Metallurgy. Dr. Ringrose is a full-time employee of Cullen Resources Limited. He has sufficient experience which is relevant to the style of mineralisation and types of deposits under consideration, and to the activity which has been undertaken, to qualify as a Competent Person as defined by the 2012 edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves”. Dr. Ringrose consents to the report being issued in the form and context in which it appears. Information in this report may also reflect past exploration results, and Cullen’s assessment of exploration completed by past explorers, which has not been updated to comply with the JORC 2012 Code. The Company confirms it is not aware of any new information or data which materially affects the information included in this announcement.
ABOUT CULLEN: Cullen is a Perth-based minerals explorer with a multi-commodity portfolio including projects managed through a number of JVs with key partners (Rox, Fortescue and Liontown), and a number of projects in its own right. The Company’s strategy is to identify and build targets based on data compilation, field reconnaissance and early-stage exploration, and to pursue further testing of targets itself or farm-out opportunities to larger companies. Projects are sought for most commodities mainly in Australia but with selected consideration of overseas opportunities. Cullen has a 1.5% F.O.B. royalty up to 15 Mt of iron ore production from the Wyloo project tenements, part of Fortescue’s Western Hub/Eliwana project, and will receive $900,000 cash if and when a decision is made to commence mining on a commercial basis – E47/1649, 1650, ML 47/1488-1490, and ML 08/502. Cullen has a 1% F.O.B. royalty on any iron ore production from the following tenements – E08/1135, E08/1330, E08/1341, E08/1292, ML08/481, and ML08/482 (former Mt Stuart Iron Ore Joint Venture – Baosteel/Aurizon/Posco/AMCI) and will receive $1M cash upon any Final Investment Decision. The Catho Well Channel Iron Deposit (CID) has a published in situ Mineral Resources estimate of 161Mt @ 54.40% Fe (ML 08/481) as announced by Cullen to the ASX – 10 March 2015.

| Section 1 Sampling techniques and data | Section 1 Sampling techniques and data | |
|---|---|---|
| Criteria | JORC Code explanation | Comments |
| Sampling technique |
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 XRF instruments, etc.). These examples should not be taken as limiting the broad meaningof sampling. |
Sampling was by Toyota-mounted auger drill rig taking samples from 0.5 to 1.5m depth. Drilling was a first pass sampling program targeting areas of interpreted geological and/or geophysical interest for gold mineralisation. 579 samples at 400 x 100m spacing – vertical holes. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used |
The sample positions were located using handheld GPS units with an approximate accuracy of +/- 5 m. |
|
| 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 1m samples from which 3kg 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 (eg submarine nodules) may warrant disclosure of detailed information. |
Notes taken of depth of sample and colour observations. Samples (~500g) were sent to Perth laboratory Minanalytical for analysis. |
|
| Drilling technique |
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.). |

Field duplicate samples were taken each 25m and standards and blanks were submitted with Gyro generated samples. |
