Helix Resources Limited ( ASX: HLX ) is pleased to provide a quarterly activities and cashflow report for the period ending 30 September 2021. The quarter saw the Company materially advance its Canbelego joint venture copper project (Helix: 70%, Aeris Resources (ASX:AIS): 30%) and its wholly owned CZ copper deposit[2] , both located in the Cobar region of central NSW (see Figure 1).
Commenting on the September quarter, Helix’s Managing Director Mike Rosenstreich said:
“We are hitting copper in just about every hole we drill at Canbelego and at CZ. With a new, highly experienced exploration team we are confident of piecing together the geological controls on the high-grade copper zones. As well as our own recent drill data, there are many historical drill holes not logged or fully sampled, so there is a huge opportunity to advance our geological understanding to make new discoveries.”
“The CZ deposit has been of particular focus for the Company this quarter as we seek to unlock its potential. CZ sits in a major regional copper bearing structure, and we believe strongly in the prospectivity for deposits like Aeris’ long-lived Tritton operations which includes the new high-grade Constellation and Kurrajong discoveries.
“Not only have we improved our presence in the Collerina trend via the drill bit, but Helix was also able to execute an agreement with Alpha HPA to expand the tenure held. I am excited by our increasing foothold and our upcoming results. The Company will continue to keep shareholders informed as these results are received.”

1.1. Canbelego Joint Venture Project (Helix 70% and Aeris Resources Ltd ASX.AIS 30%)
The Canbelego Project is a joint venture (JV) with Aeris Resources Limited (ASX: AIS). Helix holds 70% and is Manager and Aeris holds 30% and is contributing to the planning and the expenditure. There is a historical 2004 JORC Inferred Mineral Resource at Canbelego of 1.5Mt at 1.2% Cu[3] . This prospect was last drilled in 2013 at which time downhole electromagnetic (DHEM) surveys generated conductive models potentially representing copper mineralisation, which were never tested. This 2013 DHEM data was recently re-processed and interpreted by Southern Geoscience with updated geology and evolved EM modelling algorithms to refine prospective drill targets for the 2021 program which commenced in April.
During the quarter the Company completed the preliminary five-hole diamond drilling campaign for nearly 2,000 metres drilled and received assay results from all holes. Not only was the campaign highly successful in identifying massive copper sulphides in CANDD002, returning 14 metres at 4.2% copper[4] , but assays received during the period for CANDD003 - CANDD005 have confirmed the presence of additional copper mineralisation (see Figure 2).
A list of significant drill intercepts at a range of copper cut-off grades is presented in Table 1 and the drillhole collar details are presented in Table 2.
Additional mineralised intervals from CANDD003 and CANDD004 have also been submitted for assay, with anomalous copper results, important for geological interpretation.

Notably, a DHEM survey for CANDD005 identified a modelled conductor plate that aligns with the down-dip position of the CANDD002 intersection, suggesting continuation of the mineralised zone, which remains open at depth.
Work is ongoing to update the geological model based on the recent drill and geophysical data. A review is also underway considering historical data with the aim of better resolving the geological controls on the higher-grade copper zones. The JV plans to workshop these updated concepts ahead of a further round of drilling.

1.2 Central Zone (CZ) Project - Collerina Copper Trend (Helix 100%)
The CZ deposit is owned 100% by Helix and comprises an Inferred and Indicated Mineral Resource of 2.0Mt at 2.02% Cu and 0.1g/t Au[6] . The Project lies along the regional scale Collerina Copper Trend which continues north and hosts high-grade copper deposits such as Tritton, Murrawombie, Constellation and Kurrajong discovered and owned by Aeris Resources. Similar, to these deposits, at CZ, high-grade copper mineralisation appears to be developed in late-stage structures, possibly related to regional scale folding.
The Company is using the opportunity to diamond drill for metallurgical samples to also gain valuable geological and structural data from the large-diameter diamond drill core, which the historical reverse-circulation (RC) drill holes in the area don’t provide. The drilling is also designed to test for potential resources extensions of the shallow oxide-copper mineralisation and down plunge of the defined ‘central’ copper-sulphide shoot, as well as to the north and south.(Refer Figure 2 & 3).

The following section includes descriptions of visual estimates of copper and zinc mineralisation intersected in the new drilling. Various RC and diamond core samples are being prepared for assay with results expected sometime in November 2021. Please refer Cautionary Note below on page 9 .
Metallurgical and Resource Extension Drilling
The September quarter saw Helix Resources make considerable strides at the CZ deposit[7] , commencing a 3,500-metre drilling campaign utilising both RC and diamond core drilling. The CZ drilling comprises diamond core to provide samples for metallurgical test work and a mixture of RC and diamond core tails for copper resource extension and definition.
Four PQ (large 85mm diameter) and HQ (standard 64mm diameter) diamond core holes have been drilled for 663.3 metres. Each of the four holes intersected copper mineralisation, as summarised below:
-
CODD0132 intersected 10m of copper oxide mineralisation from 32m down hole.
-
CODD0133 intersected 18m of copper oxide mineralisation from 39m down hole
-
CODD0134 intersected two massive sulphide intervals, with an upper interval 3.3m from 84.7m down hole, and a lower 3.2m interval from 102.3m down hole (Figure 4).
-
CODD0135 intersected a 2.4m massive sulphide interval from 156.6m down hole.
All assays are pending.

Figure 4: CODD0134 101.5m to 106.2m showing massive sulphide from 102.3m to 105.5m comprising stratiform fine-grained pyrite and chalcopyrite
No metallurgical testing has previously been undertaken on the CZ mineralisation and the larger diameter drill core maximises the amount of sample available.
It is important to commence the commercial assessment of this mineralisation by understanding how the different mineralisation styles, oxide, transitional and sulphide respond to ‘standard’ processing flow sheets. Helix has engaged IMO Metallurgical in Perth to advise and undertake the initial characterisation testwork.
In addition, shallow CZ Resource extension exploration has also reached completion with seven RC holes drilled for a total of 599 metres. The RC holes tested up dip and along strike from existing mineralisation (Figure 5).

Visible copper was encountered in four of these holes, identifying a significant thickness of previously undiscovered mineralisation. It is anticipated that the copper oxide component of the Mineral Resource[8] at CZ will increase after assay results are received and processed.
A summary of the visual results for the oxide holes is provided in Table 3.

Finally, Helix has also completed seven RC pre-collars for 721 metres with an additional 1,400 metres of diamond core tails to be drilled at these pre-collar locations. This phase of the drilling program will target deeper extensions to the primary mineralised zone of the CZ deposit. The diamond drilling was in progress at the end of the quarter and will continue into the December quarter.
Two further holes remain ‘undesignated’ in the State approved 20-drill hole program, and these holes (likely pre-collared diamond holes) will be designed after further review of ongoing results.
CAUTIONARY STATEMENT ON VISUAL ESTIMATES OF MINERALISATION
References in this announcement to visual results are from diamond core drilling and RC drilling. Visible oxide mineralisation in PQ core drilling (CODD0132 and CODD0133) consisted of gossan (hematite and goethite) with trace chalcocite, trace copper hydroxides and minor native copper for the intervals listed on page 6. Fresh sulphide mineralisation in PQ core drilling (CODD0134 and CODD0135) consisted of 10% to 90% massive stratiform pyrite with up 5% chalcopyrite and trace sphalerite. Visible oxide mineralisation in RC drilling comprised the copper hydroxide minerals azurite and malachite in variable abundance ranging from 0.5% to 3% in one metre samples for the intervals listed in Table 3.
Visual estimates of percentages are based on sieved RC chips and therefore may not be representative of the entire sample as gangue minerals may be washed through the sieve. Laboratory assays are required for representative estimates of copper abundance. All RC holes have been sampled in one metre intervals and submitted to the laboratory for analysis. Results are expected in November 2021. The PQ diamond core holes are currently being cut into one metre half PQ core samples and will be submitted to the laboratory in midOctober 2021 with results expected in late-November 2021. Refer to ASX report “CZ Copper Drilling Update – Positive Progress” 14 October 2021 for further details.
1.3 Regional Copper Exploration
Approval has been received from the NSW Resources Regulator for a regional exploratory auger drilling campaign comprising approximately 1,000 shallow holes in the northern section of the Collerina Trend within EL74385. This work is expected to commence in November subject to finalising an appropriate drilling contractor and cropping cycle.
The program is designed to follow-up on several high-priority VTEM targets identified in March 2021 in the Hermidale/Qanda prospect area at the north of the tenement. As well, the Company filed an application for an additional exploration licence (ELA6339) to ensure coverage of high-priority VTEM targets identified in the south of the Collerina Trend, on the western boundary of the existing tenement, near Five Ways. Surface EM surveys are also planned for these prospects as soon as cropping activity is complete. (Figure 6)

2. Business Development
Helix is actively assessing and generating opportunities to support its copper business strategy to add to its copper inventory by regional consolidation, joint venture and acquisitions in addition to its planned growth through exploration success. As well, it is working on extracting value on its noncore assets such as its Chile copper projects and its iron ore royalty interests.
2.1 Cobar Region Tenement Expansion (& Nickel Cobalt Opportunity)
During the period, Helix Resources entered into a binding agreement with Alpha HPA Ltd (ASX: A4N) to further consolidate its ground position in the Cobar region of New South Wales via the acquisition of prospective copper tenure, removal of pre-existing JV restraints and acquisition of
Page 10
==> picture [18 x 51] intentionally omitted <==
a nickel-cobalt Mineral Resource[10] for issue of 20 million Helix shares Settlement of the transaction is subject to approval by Helix shareholders at the Company’s Annual General Meeting on 23 November 2021.
Under the terms of the binding Offer Letter, Helix will acquire EL8703 from Alpha HPA’s 100%owned subsidiary Solindo Pty Ltd (“Solindo”). The Company considers the tenement prospective for ‘Collerina type’ copper/base metal deposits as well as nickel-cobalt mineralisation (see Figure 7).
The transaction also extinguishes all ‘deemed’ joint venture rights as well as reduces and standardises the Royalty impost with Alpha HPA to retain a 1.0% NSR Royalty on all metals from the tenements reduced from a 1.5% NSR.
Helix views the acquisition as a strategic opportunity with EL8703 neighbouring EL8768 (former JV tenement) which holds Helix’s CZ Deposit[11] among other advanced targets. Under the transaction with Alpha HPA, the tenement title for EL8768 (currently in the name of Solindo) will be transferred to Helix.
The final element of the transaction is the acquisition by Helix of 100% of the nickel-cobalt Mineral Resource at Homeville and all nickel-cobalt rights previously held by Alpha HPA which applied to Helix’s existing tenements and EL8703. Homeville has an Indicated and Inferred Mineral Resource of 17.9Mt grading at 0.89% nickel (Ni) and 0.06% cobalt (Co)[12] .
To the northeast of Homeville deposit, the Company has intersected high-grade nickel and cobalt in drilling completed in 2018[13] , which returned significant intercepts of:
-
12m at 0.12% Co within 21m at 0.6% Ni, 0.10% Co to EOH in HCOAC018
-
8m at 0.18% Co within 18m at 0.9% Ni, 0.10% Co to EOH in HCOAC019
-
4m at 0.12% Co and 5m at 1.0% Ni, 0.05% Co to EOH within 21m at 0.7% Ni, 0.07% Co to EOH in HCOAC022
-
4m at 0.20% Co in HCOAC028
-
32m at 1.0% Ni within 64m at 0.7% Ni, 0.04% Co to EOH in HCOAC015.
-
12m at 1.2% Ni, 0.07% Co within 24m at 1.0% Ni to EOH in HCOAC016
This mineralisation occurs in thick zones of laterite from near surface, with numerous holes ending in mineralisation. There appears ample scope to extend mineralisation in multiple directions.
The Company envisages transferring the nickel-cobalt assets and rights into a 100% owned subsidiary to provide flexibility on future funding options such as attracting external investment. After preliminary exploration work and a metallurgical and development review, a broader investment strategy regarding these assets will be finalised.
2.2 Chile Divestment
The Company currently owns 100% of three highly prospective early-stage copper (and gold) projects in an accessible, low elevation area in Chile. Progress to divest or farm-out these projects has been impeded by the need to remedy various legacy financial matters and update the exploration concessions. This is now almost complete – but has caused the Company to

spend approximately $82k this quarter (approximately $322K to date this calendar year), which was not planned. Working with specialist advisors in Santiago, the divestment process has restarted, and several parties have signed Confidentiality Agreements and are currently reviewing the data. The company now hopes to close a transaction on its Chile assets in early 2022. Work has been completed during the quarter to review existing contracts and a plan to reduce commitments is being implemented to minimise monthly holding costs during the divestment process.
3. Corporate
3.1 Financial Position

3.3 Incident Report - Environmental Regulations, NSW
The Group is subject to environmental regulations under laws of the Commonwealth and State. The Group has a policy of complying with its environmental performance obligations. However, on and from the 6 September 2021 the Company became aware of potential breaches of the NSW Mines Act including several aircore holes, hydraulic auger holes and one RC hole undertaken without the requisite statutory approval. These were drilled at various time in 2018 and between 2016 and 2020.
Helix ‘self-reported’ the suspected breaches to the NSW Resources Regulator. The Company is committed to co-operating fully with the Regulator and any investigation deemed necessary by
Page 12
==> picture [18 x 51] intentionally omitted <==
the Regulator. As of 30 June 2021, no provision has been recognised and no contingent liability disclosed in relation to the suspected breaches in the Company’s accounts as the matter is still under investigation with the NSW Resources Regulator and the outcome as yet cannot reasonably be determined by management.
A preliminary risk assessment completed by the Company indicates there are no other regulatory breaches associated with its operations.
Pending the outcome of an investigation by the Regulator, Helix has taken active steps to verify that rehabilitation was completed for the unpermitted drillholes, recompense the Landholders in respect of long-term outstanding amounts and has commenced rehabilitation of the identified historical drill area.
These non-compliance events occurred prior to the appointment of the majority of the current Directors and prior to the new management and exploration team that was appointed through 2021. The Board has now satisfied themselves that appropriate compliance measures and a suitably experienced team are in place to ensure that these types of events cannot occur in the future.

APPENDIX 1: MINERAL RESOURCES – OVERVIEW
Introduction
Helix holds ~1,500km² of tenure in the highly mineralised Cobar Basin, within central NSW, Australia (refer Figure 1). The Company has recently divided the prospective copper ground into 3 regional trends referred to as Collerina, Rochford and Meryula as shown in the figure below. The Company has two copper Mineral Resources; Central Zone (CZ) and Canbelego located on the Collerina and Rochford Trends respectively (Refer Tables 1 & 2 below).
Central Zone (CZ) Copper Deposit - Context
The CZ Mineral Resource is a high-grade copper discovery made by Helix in late 2016 along the Collerina Trend.
In June 2019, Helix announced a maiden resource estimate for the CZ deposit of 2.02 Mt at 2.03% Cu and 0.1g/t Au for 40kt copper and 9.4koz gold (Indicated and Inferred) (refer Table 1). Almost 60% of that resource tonnage sits in the Indicated categorisation, with the remainder classified as Inferred (by contained copper).
Other than results contained in this ASX release, Helix confirms that it is not aware of any new information or data that materially affects the Mineral Resource information included in Helix ASX release dated 11 June 2019, Interim Maiden Resource at Collerina Copper Project . All material assumptions and technical parameters underpinning the estimates in that release continue to apply and have not materially changed.

| Total | Combined | 2.02 | 2.0 | 0.1 | 40,400 | 9,400 |
Canbelego Copper Deposit - Context
A Mineral Resource compliant with the 2004 JORC Code was reported 7 October 2010 as presented in Table 2 below. This Mineral Resource estimate is based on a total of 39 drill holes for 8,080 metres of RC and diamond core drilling.
Since this estimate the JV has undertaken additional exploration work including drilling and geophysics which is currently being compiled and interpreted.
Table 2: Canbelego* (October 2010) (0.5% Cu cut-off)
| Classification | Type | Tonnes | Copper | Gold | Contained Copper | Contained Gold |
|---|---|---|---|---|---|---|
| Mt | % | g/t | t | Oz | ||

Historic production from the Canbelego Copper mine was reported (1920) to be ~10,000t of hand-picked ore grading 5% Cu with mining stopped at the water table at a depth of approximately 80 metres.
Canbelego is located on EL6105 which is a joint venture with local copper producer Aeris Resources (ASX: AIS). Helix holds 70% and is the Manager and AIS is a contributing, 30% partner.
Other than results contained in this ASX release, Helix confirms that it is not aware of any new information or data that materially affects the Mineral Resource information included in Helix ASX release dated 1 October 2010 Initial Copper Resources for Canbelego and Exploration Update . All material assumptions and technical parameters underpinning the estimates in that release continue to apply and have not materially changed.
