Corazon Mining Limited (ASX: CZN) (Corazon or Company) is pleased to announce that drilling has intersected nickel-copper-cobalt sulphide at the Fraser Lake Complex (FLC), within the Lynn Lake Nickel-Copper-Cobalt Sulphide Project (Lynn Lake or Project) in the province of Manitoba, Canada.
The results come from a recently completed two-hole drilling program at the FLC, approximately five kilometres south of the historical Lynn Lake Mining Centre (Figure 6), which successfully targeted a geophysical anomaly defined by new geophysical techniques (ASX announcement 13 June 2023).
Drilling identified a small ultramafic (pyroxenitic) pipe-like intrusion, with visible nickel sulphide (pentlandite) and copper sulphide (chalcopyrite) at its centre (Figure 1). The assays reflect typical low-to-medium grade Lynn Lake mineralisation and reaffirms Corazon’s interpretation that this intrusion was a single pulse of metal rich magma, and part of a more substantial, previously unrecognised, intrusive centre within the FLC.
The drilling program successfully confirmed that the innovative 3D induced polarisation (IP) and magnetotelluric (MT) geophysical survey deployed by Corazon at the FLC has been successful in directly detecting a mineralised ultramafic intrusive of only 30 metres in diameter, in an area where no other geophysical techniques have been effective.
Drilling of this target, along with a reassessment and reprocessing of all geophysical datasets, has shown that this pipe is part of a much larger pipe-like body, some 500 metres wide with a core of about 300 metres in diameter. This larger target has only

been partially tested by the new geophysical techniques (Figure 3) and has developed into a priority target of a size capable of hosting multiple mineralised pipes.
Additional high priority targets were defined by the 3D IP+MT geophysical survey, which are yet to be drilled (Figure 2). These represent a core focus for the next phase of drilling at the FLC. Further, it is noted that the geophysical survey covers only approximately 20% of the FLC (refer to Figure 5 and 6), and Corazon plans to expand the successful survey technique across the FLC.
Drilling Identifies Lynn Lake-Style Nickel-Copper-Cobalt Sulphides
The FLC is a key exploration focus for the discovery of additional nickel sulphide deposits at Lynn Lake (Figure 6). The exploration area hosts a large magmatic sulphide system, approximately six kilometres by three kilometres, which has been subject to wide-spaced drilling over a small portion of the system, of approximately 1.5 by 1.5 kilometres.
Drill holes FLC-2023-057 and -058 targeted a ground MT conductive anomaly (MTC-3 in Figure 2), approximately 80 metres in diameter, that is pipe-like in form and extends from near surface to more than 700 metres below surface (Figure 4).
Drilling intersected a pyroxenite of approximately 30 metres in diameter, with a two to three-metre sulphide rich zone at the centre (core) of the intrusion. Both holes intersected this central mineralisation at about 170 metres apart down-dip (Figure 4), and returned –

==> picture [10 x 10] intentionally omitted <==
FLC-2023-058 : 0.88m @ 0.40% Ni and 0.09% Cu from 24.80m
The peak result was about 0.8% nickel. These grades are consistent with low to medium grade Lynn Lake mineralisation.
Drill hole FLC-2023-057 into anomaly MTC-3 also intersected 55.4 metres of complex sulphide mineralisation (the Sulphide Zone in Figure 4), including metre scale intervals of massive sulphide, intermixed with semi-massive to disseminated style sulphide mineralisation. Geochemistry supports this sulphide zone being a mixture of barren sedimentary sulphide and mineralised magmatic sulphide.

Significantly, this large (predominantly barren) massive sulphide body does not form part of the MT conductivity anomaly targeted by the drilling.
The best magmatic (nickel and copper bearing) sulphide incept was low-grade and fine-grained in characteristic, possibly suggesting a rapid precipitation of the sulphides, which would prevent the time required for nickel and copper enrichment.

Within the Mining Centre, this tenor of mineralisation (with a 1:1 Ni/Cu ratio) would be categorised as “marginal gabbroic mineralisation” - an early mineralising event, which surrounds the orebodies.
Table 1 provides a summary description of this mineralisation.

Image plan of VTEM conductivity at surface. Hot colours depict high conductivity.
Target MTC-3 appears within a much larger VTEM conductive geophysical anomaly – the majority of which has yet to be tested by the definitive 3D IP+MT geophysical survey methods.
The VTEM conductor is annular in shape, with target MTC-3 located on the western inside edge of the “contact halo”. Very little historical drilling has targeted the marginal zone of this VTEM anomaly (where the MTC3 MT metalliferous conductive pipe is located).
Given the nickel and copper anomalism within drill holes FLC-2023-057 and -058, the central area of the VTEM anomaly is a priority exploration target for nickel sulphide deposits.

Bigger and Better Targets Identified
Target MTC-3 is a conductive geophysical anomaly defined by a 3D ground MT survey. Although it is the first anomaly to be drill tested from the recently completed innovative 3D IP+MT geophysical survey (ASX announcement 13 June 2023), it is not the highest priority target generated from the survey. Seasonally wet ground conditions have prevented access to the other significant targets and as such Target MTC-3 was the only opportunity for a quick, initial test of these new geophysical exploration techniques.
In the Lynn Lake area, the nickel sulphide deposits occur in clusters and are hosted by mafic to ultramafic gabbroic intrusive bodies impacting each other, with the later phases being more mineralised and more ultramafic in composition. The orebodies within the Mining Centre have a spatial and timing association with late pyroxenites/peridotites (ultramafics that typically have dense geophysical characteristics). This relationship suggests there is good potential for exploration at the FLC, which hosts multiple dense, pipe-like bodies, as defined by Corazon’s recent Air Gravity geophysical survey (Figure 5).
The cause of the MTC-3 anomaly is interpreted as a metalliferous pyroxenitic pipe-like intrusion of only approximately 30 metres in width (where drilled), extending to a depth of more than 700 metres (the effective depth extent of the geophysical survey). Interpretations are that it is a single pulse of an early mineralising event that intruded a larger pipe-like body that has previously intruded the large, barren FLC gabbro (Figure 3).
As can be seen in Figure 3, the drilled pyroxenite is a small part of a much larger pipe, defined as a conductive body by a VTEM (versatile time domain electromagnetic) aerial geophysical survey. This VTEM feature has previously been dismissed as being caused by a large country rock xenolith, which hosts barren, geophysically conductive, volcanogenic massive sulphide (VMS) material, caught up in the FLC gabbro.
The MTC-3 pipe, where drilled by hole FLC-2023-057, has intruded a near surface, barren sedimentary sulphide (possibly a volcanogenic massive sulphide within country rock material). These barren sedimentary sulphides are very conductive, but typically small, flat-lying bodies, which could not be the source of the deep-rooted (+700 metres below surface) MT anomaly. These sulphides are marginal to, and do not seem to form part of, the targeted MTC-3 MT conductive anomaly.
The initial logging of drill hole FLC-2023-057 identified a significant amount of “basalt” (xenolith material) in the upper parts of the hole. Assay results also identified very fine-grained gabbro, interpreted to be the finer-grained contact halo of the annular intrusion shown in Figure 3. This material has subsequently been intruded by later sulphide bearing gabbro-norite and the pyroxenite of MTC-3.
The drilled pyroxenite intrusion causing the MT conducive anomaly MTC-3 is internal to this annular feature. This annular anomaly has geochemical and geophysical characteristics very similar to the EL Pipe within the Lynn Lake Mining Centre. The EL Pipe hosts the highest-grade nickel-copper-cobalt sulphide deposit at Lynn Lake.
Background to Geophysical Targets
Corazon’s recently completed innovative3D IP+MT geophysical survey utilised Quantec Geoscience’s powerful Orion 3D DCIP and MT Deep Imaging system. This survey was a test of the methods, designed to map the sulphide dispersion in 3D to a depth of at least 700 metres. The ground-based geophysical survey was completed on a small test area (Figure 6), approximately 2.3 by 1.2 kilometers covering only 20% of the total interpreted extent of the FLC intrusive body, where past drilling has defined good levels of magmatic nickel-copper-cobalt sulphide mineralisation.
Initial interpretation of the 3D IP and MT survey data has defined three MT conductive (low resistivity) anomalies, which represent new priority drill targets; MTC-1, MTC-2 and MTC-3 (Figure 2) (ASX announcement 13[th] June 2023).
MTC-1 is adjacent (200 metres to the southeast) and sub-parallel to the Matrix Trend (a mineralised IP chargeability high) and on-trend with pipe-like gravity high bodies identified by a recent Air Gravity survey (ASX announcements 17[th] January 2022, 11[th] April 2022, 23[rd] August 2022), suggesting a strong structural control. Broad intercepts of disseminated and matrix to net-textured sulphide mineralisation intersected by Corazon’s drilling (to date) at the FLC are geophysically coincident with chargeability-high anomalies that appear connected to MTC-1. This is the highest priority target defined.

==> picture [125 x 29] intentionally omitted <==
MTC-2 is located at the intersection of the Matrix Trend induced polarisation (IP) high anomaly (indicating disseminated sulphides) with a northwest trending deep crustal gravity structure, and adjacent to an Air Gravity-high, pipe-like body.
MTC-3 is not coincident with any interpreted controlling structures, is distal to the Air Gravity pipe-like bodies and hence has been considered a lower priority compared to the other two targets. A higher tenor of MT conductance for MTC-3 is also a point of difference to the other conductors identified.
MTC-1 and MTC-2 appear structurally controlled and are on-trend with dense pipe-like features. Both are marginal to IP chargeability highs (likely representing disseminated sulphide). MTC-3 is located beneath an area of very strong surface geophysical conductance, caused by sulphidic country rock xenoliths caught up in the gabbroic intrusion, which has geophysically limited the effectiveness of electrical geophysical methods (IP or EM) at depth.
The cross-section in Figure 4 shows the MTC-3 conductive feature, with a core of approximately 80 metres in diameter, extending to at least 700 metres below surface.

Next Steps at Fraser Lake
The MTC-3 anomaly was the first to be tested, due to being the most easily accessed. Drilling of targets MTC-1 and MTC-2 is planned to be conducted in the next phase of drilling, subject to ground conditions. Typically, the best time for regional exploration drilling at Lynn Lake is during winter. However, access to priority targets within the FLC will continue to be monitored, such that drilling can occur at the earliest possible time.
The 3D IP+MT geophysical method has proven to be a very effective in defining mineralising intrusive events. Plans are being developed to extend the test survey area to include other prospective targets within the FLC.
Other Project Activities
Corazon Mining Limited (ASX: CZN) is an Australian mineral resources company with a portfolio of battery minerals projects in Australia and Canada. The Company’s core commodities focus – nickel sulphide, copper and cobalt – positions it to take advantage of the massive demand for these metals which are critical inputs for the booming global rechargeable battery sector.
Corazon’s core asset is the Lynn Lake Nickel-Copper-Cobalt-Project (Lynn Lake) in Manitoba Province, Canada. Corazon has consolidated the entire historical mining centre and surrounding tenure under its sole ownership – the first company to do so in this major nickel producing district, since mine closure in 1976 (Figure 3). Lynn Lake hosts a large JORC compliant nickel-copper-cobalt resource and presents Corazon with a major development opportunity that is becoming increasingly prospective due to increases in metal prices, and their strong demand outlooks as core components in the emerging global rechargeable battery industry.
New mining and processing studies are underway for the Lynn Lake Mining Centre. Metallurgical test work, including innovative ore-upgrade processing, is currently being completed. Mining studies are focused on defining costs to be included in the future mine design, and, in particular, options for shaft refurbishment and function. The resource estimates for Lynn Lake are also being updated to include new knowledge acquired from recent orebody analysis. Mining studies will be completed on a deposit-by-deposit basis, as these resources are progressively upgraded.
In Australia, Corazon is exploring the Miriam Nickel-Copper Sulphide and Lithium Project (Miriam) in Western Australia and the Mt Gilmore Cobalt-Copper-Gold Sulphide Project (Mt Gilmore) in New South Wales.
Miriam is a highly prospective nickel sulphide exploration project and represents a strategic addition to Corazon’s nickel sulphide asset portfolio. Recent exploration by Corazon has also identified the potential for lithium (spodumene) bearing pegmatites at the Miriam Project (ASX announcement 29 March 2023). Corazon is currently securing drilling permits for a first-phase drilling program at priority nickel sulphide and lithium targets.
Mt Gilmore is centered on a regionally substantive hydrothermal system with extensive copper, cobalt, silver and gold anomalism, including high-grade rock chip samples over a strike of more than 20 kilometres. Mt Gilmore also hosts the Cobalt Ridge Deposit - a unique high-grade cobalt-dominant sulphide deposit. The University of Tasmania has been engaged to undertake “mineral geochemistry vectoring analysis”, which utilises proprietary science designed to identify the location of the heat source of “large porphyry copper deposit(s)”, that the University expert geologists believe are the cause of the surface mineralisation/alteration at Mt Gilmore.

==> picture [125 x 29] intentionally omitted <==
Competent Persons Statement :
The information in this report that relates to Exploration Results and Targets is based on information compiled by Mr. Brett Smith, B.Sc Hons (Geol), Member AusIMM, Member AIG and an employee of Corazon Mining Limited. Mr. Smith has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity that 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”. Mr. Smith consents to the inclusion in the report of the matters based on this information in the form and context in which it appears.
Canadian geologist Dr Larry Hulbert has been engaged by Corazon as an expert in magmatic nickel suphide deposits. Dr Hulbert has extensive knowledge of the Lynn Lake district and over 40 years’ experience in Ni-Cu-PGM exploration and research. Dr Hulbert is one of North America's foremost experts on magmatic sulphide deposits and would 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”.
Dr. Hulbert has authored numerous professional papers, was the recipient of the Barlow Medal from CIM in 1993, a Robinson Distinguished Lecturer for the Geological and Mineralogical Association of Canada for 2001-2002, and in 2003 received the Earth Sciences Sector Merit Award from Natural Resources Canada.
This announcement presents results of an “Orion 3D DCIP and MT Deep Imaging geophysical technique”, work undertaken by Quantec Geoscience. Quantec Geoscience is an accredited geophysical consultancy who have developed the Orion geophysical method for targeting large sulphide systems.
The results of the 3D DCIP and MT survey have been audited, processed and interpreted by the Company’s consultant geophysicist and ‘expert’, Martin St-Pierre (P. Geophysicist) from St-Pierre Geoconsultant Inc., based in British Colombia, Canada. He has consulted for numerous mining companies including majors and has extensive experience in magmatic nickel sulphide exploration. He was part of the team that received an excellence in exploration award from BHP for the Ekati diamond mine discovery. Mr St-Pierre consents to the release of this geophysical interpretation as it appears within this announcement.
Forward Looking Statements
This announcement contains certain statements that may constitute “forward looking statement”. Such statements are only predictions and are subject to inherent risks and uncertainties, which could cause actual values, results, performance achievements to differ materially from those expressed, implied or projected in any forward looking statements.
Forward-looking statements are statements that are not historical facts. Words such as “expect(s)”, “feel(s)”, “believe(s)”, “will”, “may”, “anticipate(s)” and similar expressions are intended to identify forward-looking statements. These statements include, but are not limited to statements regarding future production, resources or reserves and exploration results. All such statements are subject to certain risks and uncertainties, many of which are difficult to predict and generally beyond the control of the Company, that could cause actual results to differ materially from those expressed in, or implied or projected by, the forwardlooking information and statements. These risks and uncertainties include, but are not limited to: (i) those relating to the interpretation of drill results, the geology, grade and continuity of mineral deposits and conclusions of economic evaluations, (ii) risks relating to possible variations in reserves, grade, planned mining dilution and ore loss, or recovery rates and changes in project parameters as plans continue to be refined, (iii) the potential for delays in exploration or development activities or the completion of feasibility studies, (iv) risks related to commodity price and foreign exchange rate fluctuations, (v) risks related to failure to obtain adequate financing on a timely basis and on acceptable terms or delays in obtaining governmental approvals or in the completion of development or construction activities, and (vi) other risks and uncertainties related to the Company’s prospects, properties and business strategy. Our audience is cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof, and we do not undertake any obligation to revise and disseminate forwardlooking statements to reflect events or circumstances after the date hereof, or to reflect the occurrence of or non-occurrence of any events.
The Company believes that it has a reasonable basis for making the forward-looking Statements in the announcement based on the information contained in this and previous ASX announcements.
The Company is not aware of any new information or data that materially affects the information included in this ASX release, and the Company confirms that, to the best of its knowledge, all material assumptions and technical parameters underpinning the exploration results in this release continue to apply and have not materially changed.

Where exploration has been completed by other parties, those parties have been referenced in this document or within previous ASX announcements by the Company. In particular refer to CZN ASX announcement dated 11 April 2016. Lynn Lake is an historical mining centre, discovered in the late 1940’s, explored and operated as a mine by the company Sherritt Gordon up until 1976. Subsequent to mine closure, the tenure has been in part owned by multiple parties. Corazon has consolidated the mining centre and all prospective exploration ground, for the first time since mine closure in 1976. |

reporting of Exploration Results. | Known nickel-copper-cobalt magmatic sulphide deposits in the Lynn Lake Mining Centre are typically “pipe-like” in form, averaging between 80m and 120m in strike, 30m to 60m in width and with vertical extents of 100’s of metres. The historically mined deposits in the Lynn Lake area have been developed to a maximum depth of approximately 1,100 metres. |
| Multiple sulphide pipe-like deposits have been identified and mined in the Lynn | ||
| Lake area. The core of these bodies can be massive sulphide bodies or | ||
| sulphide breccia bodies, grading out in sulphide intensity to weakly | ||
| disseminated at the margins. | ||
| The ‘form’ of the mineralised bodies within the Fraser Lake Complex is less | ||
| defined. Drilling to date supports concentrations of sulphide proximal to | ||
| sedimentary xenoliths and interpreted structures. Gravitational accumulation | ||
| of sulphide minerals is also widely observed. |
