Highlights:
Robe Mesa Iron-Ore Project
-
Pre-Feasibility Study (PFS) announced to the ASX on 10 December 2020[1] on CZR’s 85%-owned Robe Mesa iron ore Project in WA’s Pilbara
-
The PFS found:
-
Robe Mesa has potential to generate strong financial returns based on the PFS production target[1] of 2Mtpa of Direct Shipping Ore (DSO) over +5 years (64 months).
-
Pre-production capital estimate of A$51.1M and a Life of Mine (LOM) average C1 cash operating cost of A$64.78/t (dry).
-
PFS LOM project cashflow of A$96.4M, based on a 62% Fe Index Price of US$90 per dry metric tonne (dmt) and a US$:A$ exchange rate of US70c.
-
LOM Project cashflow of A$622M, using US$145/dmt as the 62% Fe Index Price and all other revenue drivers as per the PFS.
-
Production is an all-fines DSO product, using crushing and screening, haulage over 450km and export via the Utah Bulk Handling Facility (Utah Point ) in Port Hedland.
-
CZR signed an MOU with Onslow Marine Support Base, which provides an opportunity to study the potential reduction in costs by hauling ore only 180km to a port facility at Onslow.
-
Feasibility Study now underway with the aim of accelerating Robe Mesa development timetable

CZR Resources Ltd (ASX: CZR) (“ CZR ” or “ Company ”) is pleased to report on what was a pivotal quarter for the Company as it completed the Pre-feasibility Study on its highly promising Robe Mesa iron ore project in WA’s Pilbara.
Corporate
CZR Resources Ltd has a controlling joint-venture interest in five exploration projects in Western Australia with Creasy Group. Activities during the quarter were distributed across the Robe Mesa Iron-Ore deposit on the Yarraloola Project, the Croydon Gold Project and the Shepherds Well Project in the Pilbara and the Buddadoo project in the Murchison Province of the Yilgarn.
During the Quarter, CZR underwent a Board re-structure with the appointment of Anna Neuling and Wayne Bramwell as Non-executive Directors and the resignations of Adam Sierakowski and Stephen Lowe (CZR release to ASX: 3 November 2020).
YARRALOOLA IRON ORE (includes Robe Mesa) – WEST PILBARA (CZR 85%)
The Yarraloola iron-ore project (E08/1060, E08/1686, E08/1826 MLA08/519) covering an area of 206 square kilometres, about 100 kilometres southwest of Karratha contains the Robe Mesa, Robe East Extension and P529 direct-shipping channel iron-ore deposits (CID) and magnetite mineralisation in the Ashburton prospect (Fig 1). The CID deposits report over +90Mt @ 53% Fe (calcining to 60% Fe) of indicated and inferred JORC2012 compliant CID and there is a higher grade, upper zone on the Robe Mesa with 24.9Mt @ 56% Fe (calcining to 62.7% Fe) that now contains a JORC2012 probable ore-reserve of 8.2Mt @ 56% Fe ( Appendix A ).
In the previous Quarter, in response to the increased demand and pricing for direct-shipping iron-ore, CZR completed a strategic review on its 85% owned cluster of CID deposits that indicated there were sound technical and commercial reasons to commence a prefeasibility study (PFS; CZR release to ASX; 8 September 2020). The PFS, however, was constrained to a direct shipping ore (DSO) mining operation of 1.5 to 2.5 million tonnes per annum, focussed on the extraction of material from the higher grade 24.9 million tonnes of cap on the Robe Mesa and utilising road-trains to haul ore approximately 450 kilometres to Port Hedland and it was completed during the Quarter.

Robe Mesa Prefeasibility Study Summary
The PFS released to the ASX on 10 December 2020 on the Robe Mesa deposit showed that it is set to be technically robust and is likely to generate strong financial return based on an annual production rate of two million tonnes of DSO and a maiden JORC2012 Probable Ore Reserve for Robe Mesa of 8.2Mt at 56 % Fe ( Appendix A, Table A5 ).
The PFS estimates an average C1 operating cost of A$64.78 per dry metric tonne over the +5 year life of the project. This underpins a payback period of just 19 months using an assumed benchmark iron price of US$90/dmt and an assumed Australian dollar exchange rate of US70c ( Table 2 ).
The strong foundations highlighted for the Robe Mesa project by the PFS include:
-
A saleable product specification with existing product reference points that are well established in the market (Rio Tinto Robe Fines, FMG SSF). This style of product comprises approximately 10% of the present Australian export volume for iron ore.
-
Robe Mesa is close to existing infrastructure and major regional hubs, and therefore well supported for access and the logistics of running an operation ( Figure 1 )
CZR Resources Ltd

==> picture [161 x 30] intentionally omitted <==
-
Whilst the PFS utilises Utah Point in Port Hedland for exports, closer port options (within 100km of Robe Mesa, refer Figure 1 ) along the coast between Onslow and Dampier may present significant opportunity to reduce the haulage distance to port.
-
The terrain is favourable making access to the Mesa for mining and the construction of infrastructure relatively straightforward.
-
A simple, low strip ratio mining operation, with the PFS making use of a single excavator and four dump trucks for the primary mining fleet, operating day shift only.
-
All mining is above water table.

2Cashflow modelling and Project Payback period uses operating cost estimates inflated 1.25% annually over the life of the project.
In Iight of the strong findings, CZR has determined that it will now undertake a Definitive Feasibility Study on Robe Mesa. This will be carried out in parallel with further drilling aimed at upgrading the Inferred Resource.
MOU with Onslow Marine Support Base
In the latter stages of the Robe Mesa PFS study, which was constrained to hauling iron-ore some 450 kilometres by road to the only operating publicly available iron-ore facility in the region, CZR became aware of the development of a closer port option located at Onslow (Figure 1) .
Onslow Marine Support Base (OMSB) is a privately owned multi-user facility, with the Western Australian Department of Transport as the controlling authority. The OMSB Facility has hard-stand areas in excess of 250,000sqm ready for use, an inner and outer harbour, wharf with heavy lift facilities and channel to deeper water ( Figure 2 ). It supports on-shore to off-shore activities for the petroleum industries in the Carnarvon Basin but is planning to expand into the handling of bulk commodities.
CZR Resources Ltd

The channel and the OMSB Facility can currently accommodate a transhipping operation for the loading of iron-ore onto barges or self-propelled barges (up to 100 metres in length), before sailing to a suitable transhipment anchorage.
The channel and the OMSB Facility have the potential to accommodate the berthing of vessels for direct ship loading. The direct loading of Handymax or larger vessels requires further modelling and will require further dredging and channel widening.
The non-binding MOU with OMSB will allow CZR to investigate the potential logistical and financial benefits of utilising a second port that is significantly closer to the Robe Mesa deposit. The OMSB Facility is located approximately 180km by road from Robe Mesa, and as such represents a 60% reduction in haul distance to that which was assumed in the PFS for export through Utah Point ( Figure 1 ).
CZR in conjunction with OMSB will investigate the receival of product and product handling and storage on the landside facility, along with the loading of vessels via transhipping versus direct ship loading of vessels berthed at the facility.
Transhipment of bulk materials has been successfully deployed at numerous ports, both in Australia and overseas. CZR and OMSB will work together to understand the economics, technical, environmental and community considerations such that an optimal solution can be identified for all stakeholders.

CROYDON GOLD PROJECT (CZR 70%)
Background
The 320 square kilometres Croydon project (E47/2150) is located in the Mallina Basin between Karratha and Port Hedland. In the period since the announcement of De Grey Mining Limited’s Hemi gold discovery the area appears to be emerging as a major gold province with the potential to be of world-class scale (DEG releases to ASX; 6 February 2020 and subsequent announcements).
Croydon covers approximately 40 kilometres strike of the key regional structures of the major regional shear zone about 50 kilometres south-east of Hemi with the geology dominated by granitic, mafic and ultramafic rocks in the east and sediments of the Mallina Basin in the west ( Figure 3 ).

Figure 3 Location of the Top Camp and Bottom Camp prospects on a summary of the Geological Survey of Western Australia published 500K-scale regional geological framework of the Croydon Project (E47/2150) in the Pilbara of Western Australia.
CZR has a compilation of historical drainage, rock-chip and gridded soils assays and infilled and extended surface sampling on the project since 2018. The early work determined that the Top Camp area which covers an area of at least 1400 metres by 400 metres and had been the focus of prospector activity represented a priority target for drilling ( Figure 4 ).
The maiden Top Camp RC drill campaign in late 2019 reported 1m samples at greater than 0.5 g/t Au from 9 of the 13 holes drilled to 200 metres on 300 metre spaced sections with the best downhole intercept of 8 metres at 10.2g/t Au in CRC007 from 135 metres and this was supported by broad zones of alteration and mineralisation that included 19 metres at 0.69 g/t Au in CRC013 from 51 metres, and 7 metres at 1.4g/t Au from 58 metres in CRC009, ( Figure 4 ; CZR release to ASX: 6 February 2020).
In the previous Quarter, CZR announced 12 follow-up RC holes for 2400 metres and 3 diamond holes for 600 metres at Top Camp and all reported significant intercepts with at least one metre sample reporting Au greater

than 0.5 g/t within samples above a cut-off grade of Au at 0.3 g/t ( Figure 4 ; CZR releases to ASX; 2 September 2020, 6 October 2020). Higher grade and broader downhole intercepts were reported from the following.
CRC018 with 1 metre at 9.44g/t Au from 66 metres .
CRC021 with 2 metres at 22g/t Au from 7 metres that included 1 metre at 42.2g/t Au from 7 metres . CRC022 with 1 metre at 8.47 g/t Au from 54 metres, and 28 metres at 0.59g/t Au from 147 metres that included 9 metres at 0.95g/t Au from 148 metres .
CRC036 with 2 metres at 6.08g/t Au from 74 metres that included 1 metre at 10.1g/t Au from 74 metres .
CRC032 with 5 metres at 3.21 g/t Au from 132 metres .
CRC022 with 28 metres @ 0.59 g/t from 147 metres .

the structures from Top Camp was identifying favourable alteration with extensive evidence of historical workings that were not sampled and ranked for prospectivity.
Activities and Results
The focus of activity during the Quarter has been the extension of mapping, with the collection of a further 3,837 gridded soil-samples to provide greater coverage of the prospective structures in the Top Camp area and coverage of three independently generated targets on the eastern block of the Croydon tenement ( Figure 5 ).
All the samples have been submitted to Bureau Veritas Laboratories in Perth for gold by fire assay, major oxides by XRF on fused disk and trace-elements by lazer ablation ICPMS on a fused disk. Results will be released when they are complete.

SHEPHERDS WELL PROJECT – WEST PILBARA (CZR 70%)
Shepherd’s Well (E08/2361), with an area of 77 square kilometres, is located 60 kilometres south-west of Karratha and covers 15 kilometres of a regional shear-zone. CZR has completed programmes of soil and rockchip sampling and mapping and along sections of the shear-zone and identified an advanced nickel prospect at Dorper, a base-metals prospect (lead-zinc-silver) at Suffolk and an emerging rare-earth prospect at Awassi

BUDDADOO PROJECT – YILGARN (CZR 85%)
The Buddadoo Project (E59/1350 and E59/2349) with a surface area of 3030 square kilometres covers part of the Gullewa Greenstone Belt about 200 kilometres east of Geraldton Port and 60 kilometres from a rail siding at Morawa and is accessible by bitumen-road. The Gullewa Greenstone belt is located within the Youanmi terrain of the Yilgarn and this is the region that hosts large gold deposits near Mt Magnet, Cue and Meekatharra and the Deflector Gold Mine owned by Silver Lake Resources is approximately 5 kilometres from the western boundary of the tenement ( Figure 8 ).
CZR initially investigated part of a 6 kilometre long and 300 metre wide gabbro within the greenstone belt that contains bands of coarse-grained, massive and disseminated, vanadiferous titanomagnetite as a potential source of iron-ore for vanadium (CZR releases to ASX; 29 July 2013, 17 October 2017 and 21 November 2018). At a P80 grind-size of -45 microns the concentrate report Fe from 66-68%, V2O5 from 0.8 to 1.86%, TiO2 from 1.4 to 5.7%, and SiO2 and Al2O3 are less than 1% and is a potential feedstock for the direct smelting of vanadiferous steel from iron-ore pellets (CZR releases to ASX; 28 February 2018, 21 March 2018, 5 April 2018 and 7 February 2019).

More recently, CZR has focussed on the gold potential of Buddadoo because the tenement covers approximately 25 kilometres of the regional-scale Salt Creek shear zone and up to a 10 kilometre wide area of greenstone belt. Assays from gridded soil samples across the structures and greenstone have generated gold and copper anomalies that require follow-up drilling and the company has obtained DMIRS permission for a drilling programme.

Activities
In the latter part of the Quarter, CZR completed a programme of surface exploration that was focussed on five independently generated targets for gold mineralisation within the Gullewa greenstone belt. During a programme of mapping, the field teams collected an additional 1,688 soil and 176 rock-chip samples from the key prospect areas ( Figure 9 ). All the samples have been submitted to Bureau Veritas for gold by fire assay, major-oxides by XRF on a fused disk and trace-elements by laser ablation ICPMS on fused disk. Results will be released when they become available.

YARRIE PROJECT – NORTH PILBARA (CZR 70%)
The Yarrie Project consists of six granted exploration licences (E45/3725, E45/3728, E45/4065, E45/4433, E45/4604, and E45/4605) that cover a total of 360 square kilometres, about 160 kilometres east of Port Hedland. Yarrie is serviced by bitumen and gravel roads, a natural gas pipeline between Pt Hedland and the Telfer copper-gold mine and a BHP-owned rail connection between Yarrie mining area and Port Hedland. The Yarrie tenements are held for their potential to host high-grade (+62% Fe) iron-ore and have historical highgrade RC drill intercepts in the Cabbage Tree and Kennedy Gap prospects (CZR release to ASX; 6 August 2014).
No fieldwork was undertaken at Yarrie during the Quarter.
