SIGNIFICANT HISTORICAL EXPLORATION RESULTS AT CTCP REVEALS CONGLOMERATE AND ADVANCED STRUCTURAL GOLD TARGETS
HIGHLIGHTS
-
Croydon Top Camp Project (CTCP) has extensive areas of historical alluvial and eluvial gold recovery that commenced in the 1880’s.
-
The western block of CTCP is prospective for gold from both Witwatersrand-style conglomerate at the base of the Fortescue Group and turbidite-hosted mineralisation in the underlying basement of the De Grey Superbasin.
-
The base of the Fortescue Group requires mapping to delineate intervals of conglomerate beneath the Mt Roe Basalt, but available drainage and soil sample results indicate prospectivity for gold over some 25 km of strike length
-
CZR has outlined 3 advanced approaching drill-ready structural gold prospects using historical gold results with supporting pathfinder element anomalism in arsenic and antinomy in a basement of carbonate-silica altered turbidites within CTCP where:
-
Top-Camp prospect with auger bottom samples to 8.5g/t and historical rock-chips from veins and intercepts in an RC-hole reporting anomalous gold.
-
Middle Valley prospect with soils to 0.5g/t and historical rock-chips of veins reporting anomalous gold.
-
Golden Valley prospect with a breccia showing extensive prospector activity and a historical RAB-hole reporting anomalous gold.
-
The eastern block of CTCP where granitic and gabbroic rocks intrude sediments of the De Grey Superbasin represents a target for massive sulphide and intrusionrelated gold and base-metals.

The Company’s Chairman Adam Sierakowski commented as follows: “Years of exploration by the Creasy Group on the CTCP has enabled CZR to assess significant amounts of historical data and prioritise areas and work programmes that will generate basement targets for drilling and intervals of conglomerate at the base of the Fortescue Group for larger scale sampling.”
Background
This announcement provides further details of historical exploration activities and results on E45/2150 - known as the Croydon Top-Camp project (CTCP). CZR has signed a binding conditional Term Sheet for the purchase of a 70% interest in CTCP from the Creasy Group (Fig 1). Details of the historical exploration activities are presented in Appendix 1 and publically available material is referenced in the text. Reported results being used by CZR to outline and prioritise exploration prospects for follow-up work that will confirm their prospectivity. (Comment: Throughout the history of exploration that is documented in the publically available reports to the WA DMIRS that pre-date JORC-2102 compliance and the more recent activities documented in Appendix 1, location recorded are plotted onto and sampling methods are reported and all the assay data has been acquired from independent laboratories using standards and duplicates)
Witwatersrand-style Conglomerate Opportunity
Based on aerial imagery, the western portion of CTCP has extensive areas of disturbance along the streams and valley floors that have been produced by small-scale alluvial and eluvial mining, which commenced in the late 1800’s and has been ongoing. All these workings are proximal to and downslope of the approximately 25km long, low-angle, unconformable contact between the Fortescue Group and the underlying basement of deformed turbiditic metasediments (Fig 2). The conglomerates at the base of the Fortescue Group have become the preferred target for the source of detrital gold in a Witwatersrand-style deposit ( As documented in recent announcements by Novo Resources Corp TSX.V:NOV; De Grey Minerals Ltd ASX:DEG; DGO Mining Ltd ASX:DGO Venturex Resources Ltd ASX:VGR and Kairos Minerals Ltd ASX:KAI) .
The c. 2.77 to 2.63Ga Fortescue Group that retains a relatively flat-lying attitude, has an irregular valley-fill conglomerate at the base. These features provide an opportunity to preserve outlies of conglomerate for perhaps several kilometres across the tenement. Evidence that the basal portion of the Fortescue Group is prospective is shown by anomalous gold results that range from 5 and 2000 ppb in historical drainage samples collected in proximity to the mapped contact (Fig 2; CZR:ASX announcement on 22-11-2017 ).
Structural Gold Opportunities
In addition to the prospectivity for Witwatersrand-style detrital gold mineralisation, CTCP also contains three more advanced prospects known as Top-Camp, Middle Valley and Golden Valley where historical results indicate potential for gold mineralisation within the basement of the De Grey Superbasin (Fig 2).
First Advanced Prospect - Top-Camp
This prospect covers a structurally complex area of carbonate-silica altered turbiditic silts and sands within a broad NE-trending shear-zone (Fig 2; Smithies, 1998). On the available aerial imagery ( Bing and Google ), the valley floors and drainages are extensively disturbed by historical small-scale mining activities and a historical vein sample results were the first encouragement for further work ( WAMEX Reports: A49997 ). The first drilling in 1994 consisted of 15 shallow RC-holes that
Coziron Resources Ltd
Page 2
intersected bedrock beneath some areas of surface workings with the best intercept reported in TC7 of 4 m @ 10.6 g/t (Table 2; Fig 3; WAMEX Report A40741 ). The drilling was followed by the completion of 11 trenches to 132m long that crossed some areas of historical disturbance and the bedrock was sampled at 2m interval with anomalism reported ( WAMEX Report: A47365 ). After the drilling and costeaning, a 40 by 40m gridded soil-sampling programme produced a coherent gold and arsenic anomaly some 1.5km in length and 500m wide that covered and extended from the historical workings (WAMEX Report: A44169 ).
In 2012, a 20m by 20m gridded auger programme was used to further determine whether the metasedimentary basement in the Top Camp area was generating the anomalism in gold and arsenic reported in the work from the 1990’s ( Full details presented in Appendix 1 ). Geochemical results from the end-of-hole samples reported gold to 8.5 g/t gold (Fig 3), arsenic from 50 to 300ppm and antinomy from 3 to 33 ppm, confirming that the area is anomalous in both gold and gold-pathfinder elements. This prospect thus represents a high priority for follow-up work.
Table 1. Summary of historical exploration activities at the Top-Camp prospect.
| Year | Activity |
|---|---|
| 1994 | Rock-chips from veins at the entrance of a historical adit reportedgold to 12.7g/t |
| Feb 1994 | RC drilling of 15 holes for 706m, sampled on 4m intervals returned a best result of [email protected]/t from 16 to 20 meters(WAMEX Report: A40741). |
| 1996 | Costeans through colluvium into bedrock and sampled on 2m intervals detected gold anomalism,with a best result of [email protected]/t(WAMEX Report: A47365) |
| 1997 | Soil Sampling on 40 by 40 m grid outline a 1.5km long and 500m wide zone of gold and arsenic anomalism(WAMEX Report: A44169) |
| 2012 | Auger sampling on 20 by 20m grid over the core of the historic soil grid reports a maximum gold of 8.5g/t, arsenic to 300ppm and antimony to 33ppm. (Full details available and reported in Appendix 1) |
Second Advanced Prospect - Middle Valley
This prospect covers an interval of about 500m by 500m in carbonate and silica altered metasediments along the crest of a regional anticline with an axial-plane that is overturned slightly to the east and disrupted by NE-trending faults (Fig 2; Smithies, 1998 ). The prospectivity was identified by following up a cluster of stream-sediment samples (Fig 2, 4; WAMEX reports: A60212 and A65099 ). In this area, rock-chip sampling during mapping in 1999 and 2000 reported mineralisation in steeply dipping quartz veins ( WAMEX Report: A60212 ). These results were followed up more recently in 2016 with a 40m gridded soil-sampling program, with results showing that the area with anomalous gold is supported by arsenic up to 100 ppm and antinomy to 5 ppm, suggesting a bed-rock source. ( See Details in Appendix 1 )

2016 Gridded 40, by 40m soil sampling covering 1km[2] that reported gold to 0.5g/t ( Full details are available and are reported in Appendix 1 ).
Third Advanced Prospect - Golden Valley
This area covers faults and splays with carbonate and silica alteration in turbiditic sediments that are located near a major NE-trending structure (Fig 2, Smithies, 1998 ). In the early 1980’s, Golden Valley Mines NL undertook a programme of bulk-sampling to determine the grade of alluvial and eluvial prospects in the area and this work provides documented evidence of gold anomalism ( WAMEX Report: A44997 ). The Company also noted a spatial association between alluvial gold distribution, prospector pitting and an outcrop of a gossanous breccia. The breccia ranged in thickness from 0.5 to 5m and extended for over 2km. Follow-up work included the drilling of 15 vertical RAB holes to a depth of 30m and one RAB/RC hole to 56 m located near the breccia and selectively sampled where sulphide was observed and anomalism in gold and arsenic was reported ( WAMEX Report: A49977 ). Further work is required.

| Pre-1980 | Evidence of historical alluvial mining was mapped along the drainage systems by Golden ValleyNL(WAMEX Report: A44997). |
| 1983 | Detailed structural and stratigraphic mapping of the turbidite sequence that interpreted carbonate as a primary sedimentological feature rather than as evidence ofpotential metasomatic activity (WAMEX Report: A44997). |
| 1984 | Completion of 15 vertical RAB to 30m and one RAB/RC to 56m with gold from intervals with sulphide reporting a maximum of 2 m at 2.5g/t and arsenic to 2000 ppm(WAMEX Report: A44997). |
| 1999 | Programme of wide-spaced drainage sampling as reported with results in Mehri, 2000(WAMEX Report: A60212)and Mehri 2001(WAMEX Report: A62100). |
Comments and Future Work
The Croydon Top-Camp (E47/2150) acquisition contains prospectivity for at least two styles of gold mineralisation. The western boundary of the tenement has exposure of the low-angle basal contact of the Fortescue Group and opportunities to preserve outliers across the tenement that are prospective for melon-seed detrital gold in Witwatersrand-style conglomerate. In addition, there are three advanced gold exploration targets with an extensive history of prospector activity that potentially reflect mineralisation in carbonate and silica altered turbidites from the De Grey Superbasin.
Future work will include detailed mapping and sampling along the lower contact of the Fortescue Group. An airborne magnetic survey will also be completed to delineate any structural features that potentially act as controls for mineralisation within the De Grey Superbasin sequence. Follow-up sampling of the advanced prospects will be undertaken to locate and orient the first round of drilling.

A review of the tenor and setting of gold and base-metal anomalism on the eastern portion of E47/2150 is also progressing. In contrast to the folded turbidites in the west, the east has a largescale NE-trending shear zone with granitic and mafic rocks intruding the sedimentary rocks.
Any significant results will be reported when they are available.

| 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. |
At Top Camp in 2012 truck-mounted auger sampling was completed over areas with extensive disturbance by prospectors to recover material from the uppermost part of the bedrock on a nominal 20x20 metre grid pattern with a total of 1595 shallow holes drilled either to 1m depth or through the soil and colluvium to bedrock. A 2 to3 kg grab sample was collected by Colchis Pty Ltd at the bottom of the hole. In 2016 a soil sampling programme was completed by Colchis Pty Ltd over the Middle Valley area collecting 250g of -250micron screened material on a 40m grid over the prospective area. 2-3kg of rock-chip samples have also been collected from veins and any other rocks that potentially offerprospectivityforgoldmineralisation. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
The auger programme included 10 duplicate samples that were collected for QAQC purposes. Samples were despatched to Intertek Laboratories for multi-element analyses. |
|
| 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. |
A 2-3 Kg sample from the bottom of an auger hole was collected as an alternative to a soil sample from the areas of soil and transported cover that are extensively disturbed by prospector activity. The 250g of -250micron material from areas that have not been disturbed by prospector activity is regarded as a representative sample to reflect soil geochemistry. All samples were transported to Perth and submitted to Intertek Laboratories, pulverised and then analysed by aqua-regia digest with gold (AR25) and multi-element ICP. |

| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
Soil and rock-chip sampling is a method of providing representative surface samples to outline areas that are prospective for mineralization to high-light lithologies which require future drill assessment. Soil samples are 250gm of -250microns that are field screened material that was collected 5 to 10 cm beneath the surface. Rock-chips are 2-3kg of representative material. |
|
|---|---|---|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. |
Multiple samples are collected from each lithology | |
| 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. |
In early stage exploration, a number of 2-3kg rock-chip samples are collected at different outcrops to provide an indication of compositional variations associated with each lithology. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
In finer grained rocks, 2-3kg is sufficient to provide an indication of lithological composition. |
|
| 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. |
All analyses are from Intertek Laboratories in Perth using an aqua-regia digest on a pulverised 25gm sample with ICP finish to a detection limit of 1ppb and suite of trace- elements are reported the ICP suite. |

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. |
No weighting or truncation has been applied to the geochemical data and no intercept values are reported. No metal equivalents are presented. Gold mineralization is hosted within bedded sandstone, quartz-carbonate veins and turbiditic basement sediments. The style and geometry of other styles of mineralization have yet to be determined. No drill-hole intercepts are reported. |
| 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. |

| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
Gold mineralization is hosted within bedded sandstone, quartz-carbonate veins and turbiditic basement sediments. The style and geometry of other styles of mineralization have yet to be determined. No drill-hole intercepts are reported. Refer to Figures… in body of text All relevant samples on the maps and in the text 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. |
Relevant geological information is reported on the maps and analysis tables in the 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. |
Mapping, soil and rock-chip sampling of the gold targets and an airborne magnetic survey is proposed. |
| 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. |
Relevant geological information is reported on the maps and analysis tables in the text. |
| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). |
Mapping, soil and rock-chip sampling, 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. |
