TOP CAMP PROJECT UPDATE ON FIELD PROGRAMME AND GOLD RECOVERY
HIGHLIGHTS
-
Recent field programme collected 1109 soil samples that extend the Top Camp and Martin Prospect grids with some follow-up at other sites of anomalism. Results are expected in approximately 4 weeks.
-
A further 300 nuggets of gold weighing 64 grams of gold has been reported by two prospectors holding 40E permits from the core of the Top Camp area where carbonate-rich rocks are strongly anomalous in gold-pathfinder elements such as arsenic and antinomy. This brings the total amount of gold reported by prospectors to CZR during 2018 and 2019 to 190.7 grams.
-
Photos of the nuggets supplied by the prospectors include examples of gold in veins with quartz, carbonate and iron-oxide that will be the target of an RC drilling programme.
-
Drill-sites for a proposed 2000m RC drill program in the main part of the Top Camp area and 500m of RC drilling targeting the down-dip extension of the gold-copper gossan at Martin Prospect have now been selected. Drilling is planned to commence in late October.
Coziron Resources Limited (ASX:CZR) (“ Coziron ” or Company ”) is pleased to announce an exploration update for the Croydon Top Camp gold project (E47/2150) in the Pilbara (“ CTCP ”). Following the completion of its recent capital-raising, Coziron immediately undertook a field exploration program during the month of September in advance of commencing a drilling program on the CTCP. The Company is focussed on the potential of the preFortescue Group rocks from the basement of the Pilbara to host lode-style and related gold deposits that represent the source of most gold mined in Western Australia.

Top Camp Area - Sampling and Drill-site Selection
Soil sampling and mapping in the Top Camp to Middle Valley areas of the CTCP has focussed on extending the historical soil and auger grid to cover new areas where prospectors are reporting the recovery of gold nuggets by metal detector (Fig 1). Approximately 700 soil-samples sieved in the field at -2mm have been collected and transported to Bureau Veritas Laboratories in Perth. These have been submitted for full-suite analysis including gold by fire-assay with whole-rock XRF and lazer-ablation ICP for major and trace-elements on a fused disk. Results will begin to be received in approximately four weeks.

Top Camp Prospect - Gold Recovered by Prospectors
Coziron has received two notifications during September 2019 that included photographic confirmation of gold being recovered from 40E Prospecting permits that cover the central parts of the CTCP. The permits allow prospectors to undertake small-scale exploration for gold on the surface using hand-tools such as panning, dryblowing or metal-detecting. A condition of the issue of these permits is that the prospectors must report the

amount of gold recovered to WA Department of Industry and Safety, with a copy of the report supplied to the underlying holder of the Exploration License.
The new reports document 216 nuggets weighing 36g and 84 nuggets weighing 28g, with the largest nugget at 2.36g. These results compliment earlier reports where gold nuggets with a total weight of 126.7g were recovered from the Top Camp area (CZR:ASX 20-Sept-2018; 25-July-2019; Fig 2, Fig 3). The weight of gold recovered during 2018 - 2019 now totals 190.7g. Photographic evidence suggests that the recovered gold is being released from a quartz-carbonate rock.
Although the recovery of coarse gold particles by prospectors is not in itself economically significant, the reported distribution has been plotted and integrated with other geological and geochemical data from CTCP and is being used to identify and prioritise targets for further work.

Top Camp Prospect - Next Step Proposed RC Drilling
Drill-sites for approximately 10, -60 inclined 200m RC holes have been selected to cover two sections in the main part of the Top Camp soil and auger grid. The sections cover areas across a valley floor where there is extensive evidence of prospector activity and all the historical soil and auger samples (some of which have been re-assayed to confirm historical results) are anomalous in both gold and pathfinder elements. Geological evidence suggests that the calcareous turbiditic sandstones and siltstones have broad intervals with sulphidic quart-carbonate veins that will be the target of exploration. Drilling is planned to commence in late October.
Martin Prospect Area - Sampling and Drill-site Selection
Soil sampling and mapping in the Martin area of the CTCP has focussed on the generation of a sample grid around a small historical pit on the Martin Prospect A gold and base-metal gossan and a historical drainage sample among published records from the Geological Survey of Western Australia as having gold (Fig 4). Approximately 400 samples of -2mm soil sieved in the field have been collected and submitted to Bureau Veritas Laboratories in Perth for full-suite analysis and results will commence being reported in approximately four weeks. The purpose of the sampling is to determine the extent and tenor of geochemical anomalism surround the gossan and determine whether the occurrence of gold in the historical drainage sample can be confirmed. Soil samples have also been collected across the surface projection of a historical conductive EM-anomaly to determine whether there is any associated geochemical anomalism supporting the presence of gold and base-metals at depth.
Drill sites for approximately 500m of RC drilling have been selected to test the down-dip extension of the goldcopper gossan at Martin Prospect A. The gossan is hosted by a sequence of schists and gneisses that include mafic and felsic rocks that are interpreted as being part of a greenstone sequence that rests on a basement of granodiorite to the West and is unconformably overlain by units of the Mallina Basin to the East. Coziron is exploring the potential of the greenstone sequence as a host for volcanic-hosted massive sulphide and associated gold deposits.

Competent Persons Statement
The information in this report that relates to mineral resources and exploration results is based on information compiled by Rob Ramsay (BScHons, MSc, PhD) who is a Member of the Australian Institute of Geoscientists. Rob Ramsay is a full-time Consultant Geologist for Coziron and has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves”. Rob Ramsay has given his consent to the inclusion in this report of the matters based on the information in the form and context in which it appears.
Cautionary Statements
There are some historical exploration results and more recent reports supplied by prospectors included that have not been collected and reported in accordance with the JORC Code 2012 and the Competent Person has not done sufficient work to disclose the exploration results in accordance with JORC Code 2012. However, there is nothing that has come to the attention of the acquirer that causes it to question the accuracy or reliability of the former owner’s Exploration Results but the acquirer has not independently validated the former owners Exploration Results and therefore is not to be regarded as reporting, adopting or endorsing those results. The announcement is not otherwise misleading.

| Sampling techniques |
Nature and quality of sampling (eg 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. |
The samples reported include soil and rock-chip samples collected in 2018 and 2019 with sample numbers, locality information and descriptions recorded by employees of Coziron Resources. There are also results from pulps stored by Creasy Group from an auger drilling programme that was completed in 2012. The sample numbers on the pulps are the same as was reported for the historical analytical work. A high resolution magnetic and aeromagnetic survey to cover E47/2150 was acquired by CZR in 2018 and the independently processed images provide a framework from which much of the basement geology which is covered by a thin veneer of sand and colluvium but prospective for gold and base-metal mineralisation can be interpreted. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
In 2012, approximately 3kg of auger-spoil was collected and labelled with the hole number. The drilling method terminates the hole at the interface with hard-rock. The recovered material is regarded as a bottom of hole sample and used as the equivalent of a soil or rock-chip result. A total of 328 auger pulps were selected for more comprehensive analysis at Bureau Veritas in 2018. In 2018, Coziron collected 2-3kg of field screened -2mm of colluvial material as a soil sample and 2-3kg of rock- chips from representative outcrops for geochemical analysis. |
|
| 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. |
No sample preparation was required for the re-analysis of the auger pulps. Soil and rock-chip samples are completely pulped. A sub sample was fused and the major oxides and selected trace-element analysis are collected using XRF Spectrometry for a whole-rock silicate suite of oxides followed by a laser ablation digest and ICP finish for a suite of 60 trace-elements. Gold, platinum and palladium are measured using a fire assay on a 40g sample with an ICP finish to 1ppb detection. All preparation and analytical work was undertaken in controlled conditions at Bureau Veritas Laboratories in Perth, Western Australia. |

| Drill hole | 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: |
The tenement appears to have a basement of Archaean-age gneissic rocks that appears to have been first overlain by ultramafic mafic to mafic rocks and then deformed and metamorphosed with the intrusion of granites. The basement is then overlain by sediments of the DeGrey Basin that are turbiditic and folded and metamorphosed to greenschist facies and locally intruded by felsic rocks. Unconformably overlying the entire sequence are essentially flat-lying sediments and mafic volcanics and intrusives of the Fortescue Group. The tenement is prospective for gold and base-metals in the basement metasediments as well as the overlying unconformable sandstone of the Fortescue group and pegmatite related mineralisation in the granites. No new drill holes are reported No weighting or truncation has been applied to the geochemical data and no intercept values are reported. No weighting or truncation has been applied to the geochemical data and no intercept values are reported. |
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 |
||
| Information | 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. |
||
| Data aggregation methods |
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. |
No metal equivalents are presented. | |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
No metal equivalents are presented. Gold mineralization is hosted within bedded sandstone, quartz-carbonate veins and turbiditic basement sediments. Base-metal (Cu-Zn) is also present in ultramafic to mafic rocks of the Millindinna Intrusion. The style and geometry of other styles of mineralization have yet to be determined. No drill-hole intercepts are reported. |
| 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’). |
||
| 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. |
Refer to Figures… in body of text |
| 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. |
