- High-grade result of 7.3m @ 4.2% Cu, 0.3g/t Au & 16.6g/t Ag from 317.8m
- Including 2.5m @ 9.1% Cu, 0.5g/t Au & 31.4g/t Ag
- The result reveals a potential new lode ~250m from Corner Bay, which is the primary deposit at the Chibougamau Project; Corner Bay has Indicated Mineral Resources of 2.7Mt at 2.7% Cu & 0.3g/t Au and Inferred Mineral Resources of 5.9Mt at 3.4% Cu & 0.3g/t Au 1
- The recent intersection is associated with a significant off hole electromagnetic anomaly (530m x 460m) which has not yet been drilled
- The result highlights the potential for multiple sub-parallel lodes at Corner Bay analogous to other well-known deposits in the region; two diamond rigs are on site across both Corner Bay and other drilling targets with further results anticipated this half
- The Chibougamau district is a world class mineral terrane with high potential for additional discovery, having historically produced over 945,000t of copper and 3.5Moz of gold 2
- The Project has excellent infrastructure with a 900,000tpa processing facility, local mining town, sealed highway, airport, regional rail infrastructure and 25kV hydro power to the processing site
Cygnus Executive Chairman, David Southam said : "We are delighted to hit the ground running with an excellent intersection from a previously undrilled area which is only 250m away from main Corner Bay Deposit.
"This result supports our view that there is much more to find at Chibougamau, both near the existing deposits and in the wider region, and is consistent with our strategy to create shareholder value by growing the resource.
"The downhole geophysics is already proving to be a key tool for the project and will help us unlock other under-explored areas of the project". |
1 The Mineral Resource Estimate at the Chibougamau Project is a foreign estimate prepared in accordance with CIM Standards. A competent person has not done sufficient work to classify the foreign estimate as a mineral resource in accordance with the JORC Code, and it is uncertain whether further evaluation and exploration will result in an estimate reportable under the JORC Code.
Cygnus Metals Limited (ASX: CY5; TSXV: CYG) ("Cygnus" or the "Company") is pleased to announce that it has made an outstanding start to its exploration campaign at the Chibougamau Copper-Gold Project in Quebec, Canada, with the first hole returning assays of up to 2.5m @ 9.1% Copper .
Prior to the merger of Cygnus and Doré Copper Mining Corp. closing, both teams executed a targeted exploration program to test the immediate areas around the Corner Bay deposit, looking for both additional structures and extensions to the current resource.
The first drillhole from this program has returned an intersection of 7.3m @ 4.2% Cu, 0.3g/t Au & 16.6g/t Ag, including 2.5m @ 9.1% Cu, 0.5g/t Au & 31.4g/t Ag from a potential new lode ~250m east of the existing resource in the footwall of the Corner Bay deposit. Follow up downhole electromagnetics has since defined a significant off hole electromagnetic anomaly (530m x 460m) to the north and down dip of the intersection that has yet to be tested by drilling.

About the Drilling and Geophysical Results
The first hole of the program (CB-24-100) targeting the footwall of the Corner Bay deposit has intersected a potential new sub parallel lode with a high-grade drill result of 7.3m @ 4.2% Cu, 0.3g/t Au & 16.6g/t Ag from 317.8m, which includes 2.5m @ 9.1% Cu, 0.5g/t Au & 31.4g/t Ag .
The result highlights the potential for multiple sub-parallel lodes at the Corner Bay deposit analogous to other well-known deposits in the region. This new structure sits 250m to the east of the Main Lode at Corner Bay in an area with very little drilling. This presents an exciting target for follow up drilling and an opportunity to add to the existing resources at Corner Bay.
In addition, follow up electromagnetics (‘EM') completed on the recent drilling has defined a large (530m x 460m) conductive plate offset to the north and down dip of drillhole CB-24-100. EM is known to correspond well with the mineralisation style at the Chibougamau mining camp, being primarily composed of chalcopyrite with minor amounts of pyrite and pyrrhotite. Historically, airborne EM has been used to make some of the discoveries in the region, although ground and downhole EM has been underutilised in more recent times. The large EM plate provides a priority target for follow up exploration along this structure.

Ongoing Drilling
In line with the Company's resource growth strategy, drilling is underway with two diamond drill rigs. This initial program will focus on resource growth opportunities surrounding some of the existing deposits aiming to build upon the existing high-grade resources. The Company looks forward to a high volume of news flow during 2025 with ongoing drilling updates and results.
About the Corner Bay Deposit
Cygnus' flagship Corner Bay deposit within the Chibougamau Project is located 17km (straight line) south of the Chibougamau processing facility. The deposit was discovered in the 1980s and has never been mined although ramp access was established to 115m for the purpose of initial bulk sampling test work.
The deposit is the primary resource in the combined Project resources, making up 79% of the total resource with Indicated Mineral Resources of 2.7Mt @ 2.7% Cu & 0.3g/t Au and Inferred Mineral Resources of 5.9Mt @ 3.4% Cu and 0.3g/t Au. 1
Mineralisation extends from surface and has been defined over 1,000m of strike and to a depth of 1,350m with mineralisation remaining open in all directions. The mineralisation is structurally controlled and hosted as a north-south striking quartz-carbonate vein with semi massive chalcopyrite and minor pyrite mineralisation. The main lode has been crosscut and offset by a large diabase dyke with an upper and lower portion of the lode positioned either side of the dyke.
The Corner Bay deposit sits on the southern flank of the Chibougamau pluton and has seen minimal exploration compared to the north. The northern flank is host to 16 mined deposits and has contributed a significant portion of the regions historic production ~945,000t of copper and 3.5Moz of gold. 2 Corner Bay in the south shares comparable lithological and structural characteristics to the northern deposits, however, as the northern mines developed, multiple sub-parallel lodes were subsequently discovered within the same structural corridor. Due to the relatively early stage of defining the Corner Bay deposit, potential parallel lodes and resource extension have not yet been properly explored and the latest intersection highlights the potential for additional sub-parallel lodes within the immediate vicinity of the current resources.
About the Chibougamau Copper-Gold Project
The Chibougamau copper-gold project ("Chibougamau Project") is located in central Quebec, Canada approximately 480km due north of Montreal. The province of Quebec has been recognised as a top ten global mining investment jurisdiction in the 2023 Fraser Institute Annual Survey of Mining Companies. The project has excellent infrastructure with a local mining town, sealed highway, airport, regional rail infrastructure and access to hydro power via installed powerlines.
The Chibougamau Project is centred on the Chibougamau pluton with a district wide historic production of 53.5Mt @ 1.8% Cu and 2.1g/t Au 2 with periodic mining between the early 1900s and 2008. Over this long mining history, the district has produced over 945,000t of copper and 3.5Moz of gold from 16 former producing mines. 2
The Chibougamau Project has high-grade resources including a Measured and Indicated Mineral Resources of 3.6Mt at 2.5% Cu & 0.6g/t Au and Inferred Mineral Resources of 7.2Mt at 3.0% Cu & 1.1g/t Au with significant potential to grow. 1
The Company has a clear strategy to:
- Rapidly grow the resource through brownfield exploration and investment in drilling; and
- Advance the project towards development through study work and utilising existing infrastructure.
The Company sees a huge opportunity to create shareholder value by an established high-grade resource with opportunity for growth, excellent infrastructure, 900ktpa processing facility and clear pathway to production, all within a quality endowed mineral terrane that has seen minimal modern exploration.

APPENDIX C – 2012 JORC Table 1
Section 1 Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
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. | - All current drilling conducted at the Chibougamau Project was completed under the supervision of a registered professional geologist as a Qualified Person (QP) who is responsible and accountable for the planning, execution, and supervision of all exploration activity as well as the implementation of quality assurance programs and reporting.
- All drilling reported is NQ2 (47.8 mm diameter)
|
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. | - All sample collection, core logging, and specific gravity determinations were completed by Cygnus Metals under the supervision of a professionally qualified registered geologist.
- NQ core was marked for splitting during logging and is sawn using a diamond core saw with a mounted jig to assure the core is cut lengthwise into equal halves.
- Half of the cut core is placed in clean individual plastic bags with the appropriate sample tag.
- QA/QC is done in house by Cygnus Metals geologists with oversight from the Senior Geologist. The check samples (blanks and standards – 4% of total samples with another 2% of core duplicates taken on half split core) that were inserted into the sample batches are verified against their certified values and are deemed a pass if they are within 3 standard deviations of the certified value. The duplicates are evaluated against each other to determine mineralization distribution (nugget). If there are large discrepancies in the check samples, then the entire batch is requested to be re-assayed. The samples are then placed in bags for shipment to the offsite laboratory's facility.
- The remaining half of the core is retained and incorporated into Cygnus's secure, core library located on the property
|
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. | - Industry standard sampling practices were used with sample lengths ranging from 0.3 m to 1.0 m and respected geological contacts. Sample tags were placed at the beginning of each sample interval and the tag numbers were recorded in an MS Excel database.
- Sampling practice is considered to be appropriate to the geology and style of mineralisation
|
| Drilling techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). | - Diamond core was drilled using surface diamond rigs with industry recognised contractors Miikan Drilling. Miikan is a joint venture between Chibougamau Diamond Drilling Ltd., the First Nations community of Ouje-Bougoumou and the First Nations community of Mistissini both located in the Eeyou Istchee territory.
- Drilling was conducted using NQ core size
- Directional surveys have been taken at 50m intervals
|
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed.
Measures taken to maximise sample recovery and ensure representative nature of the samples.
Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. | - Diamond core recovery was measured for each run and calculated as a percentage of the drilled interval.
- Overall, the core recoveries are excellent in the Chibougamau area
|
Logging
| Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. | - All core was geologically and geotechnically logged. Lithology, veining, alteration and mineralisation are recorded in multiple tables of the drillhole database
|
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. | - Geological logging of core is qualitative and descriptive in nature.
|
| The total length and percentage of the relevant intersections logged. | - 100% of the core has been logged
|
| Sub-sampling techniques and sample preparation | If core, whether cut or sawn and whether quarter, half or all core taken.
If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.
For all sample types, the nature, quality and appropriateness of the sample preparation technique.
Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
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.
Whether sample sizes are appropriate to the grain size of the material being sampled. | - The NQ2 diameter the core was sawn in half following a sample cutting line determined by geologists during logging and submitted for analysis on nominal 1m intervals or defined by geological boundaries determined by the logging geologist
- Each core sample is assigned a tag with a unique identifying number. Sample lengths are typically one metre but can be depending on zone mineralogy and boundaries.
- This sampling technique is industry standard and deemed appropriate.
|
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. | - Sample (NQ size half core) preparation and fire assay analysis were done at Bureau Veritas Commodities Canada Ltd ("BV") in Timmins, Ontario, and ICP-ES multi-elements analysis was done at BV in Vancouver, B.C.
- Samples were weighed, dried, crushed to 70% passing 2 mm, split to 250 g, and pulverized to 85% passing 75 µm.
- Samples are fire assayed for gold (Au) (30 g) and multi-acid digestion ICP-ES finish, for 23 elements (including key elements Ag, Cu, Mo).
- Samples assaying >10.0 g/t Au are re-analysed with a gravimetric finish using a 30 g charge. Samples assaying >10% Cu are re-analysed with a sodium peroxide fusion with ICP-ES analysis using a 0.25 g charge.
|
| For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. | |
| Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. | - Laboratory QC procedures involve the use of internal certified reference material as assay standards, along with blanks, duplicates and replicates
|
Verification of sampling and assaying
| The verification of significant intersections by either independent or alternative company personnel. | - Verification of sampling was made by Cygnus Metals and other professional consultant geologists
|
| The use of twinned holes. | |
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. | - All logging data was completed, core marked up, logging and sampling data was entered directly into the database.
- The logged data is stored on the site server directly.
|
| Discuss any adjustment to assay data. | - There was no adjustment to the assay data
|
Location of
data points
| Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. | - The location of the drillholes and the aiming points for the orientation of the drillholes were indicated on the ground using identified stakes. The stakes marking the location of the drillholes were set up and located with a Garmin GPS model "GPSmap 62s" (4m accuracy)
- Surveys are collected using a Reflex EZ-Shot® single-shot electronic instrument with readings collected at intervals of approximately every 30 m downhole plus a reading at the bottom of the hole
|
| Specification of the grid system used. | - The grid system used is UTM NAD83 (Zone 18)
|
| Quality and adequacy of topographic control. | - A Digital Terrane Model (DTM) has been used to accurately plot the vertical position of the holes
|
Data spacing and distribution
| Data spacing for reporting of Exploration Results. | - The spacing is considered appropriate for this type of exploration
|
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. | - No resource estimation is made
|
| Whether sample compositing has been applied. | - No sample compositing has been applied
|
Orientation of data in relation to geological structure
| Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. | - Drilling is orientated approximately at right angles to the currently interpreted strike of the known interpreted mineralisation. Reported intersections appear close to true width
|
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. | - No bias is considered to have been introduced by the existing sampling orientation
|
| Sample security | The measures taken to ensure sample security. | - Core was placed in wooden core boxes close to the drill rig by the drilling contractor. The core was collected daily by the drilling contractor and delivered to the secure core logging facility. Access to the core logging facility is limited to Cygnus employees or designates
|
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. | - No audits have been undertaken, therefore information on audits or reviews is not yet available

| Geology | Deposit type, geological setting and style of mineralisation. | - Corner Bay and Devlin are located at the northeastern extremity of the Abitibi subprovince in the Superior province of the Canadian Shield and are examples of Chibougamau-type copper-gold deposits. The Abitibi subprovince is considered as one of the largest and best-preserved greenstone belts in the world and hosts numerous gold and base metal deposits.
- The Corner Bay deposit is located on the southern flank of the Doré Lake Complex (DLC). It is hosted by a N 15° trending shear zone more or less continuous with a strong 75° to 85° dip towards the west. The host anorthosite rock is sheared and sericitized over widths of 2 m to 25 m. The deposit is cut by a diabase dyke and is limited to the north by a fault structure and to the south by the LaChib deformation zone.
- The Corner Bay deposit consists of three main mineralized lodes (subparallel Main Lode 1 and Main Lode 2 above the dyke, and Main Lode below the dyke that make up the bulk of the deposit. The Corner Bay deposit has been traced over a strike length to over 1,100 m to a depth of 1,350 m and remains open at depth.
- The mineralization is characterized by veins and/or lenses of massive to semi-massive sulphides associated with a brecciated to locally massive quartz-calcite material. The sulphide assemblage is composed of chalcopyrite, pyrite, and pyrrhotite with lesser amounts of molybdenite and sphalerite. Late remobilized quartz-chalcopyrite-pyrite veins occur in a wide halo around the main mineralization zones.
- Devlin is a flat-lying, copper-rich lodes-hosted deposit in a polygenic igneous breccia that is less than 100 m from the surface. The tabular bodies have been modelled as four nearly horizontal lodes: a more continuous lower zone and three smaller lodes comprising the upper zone. Mineralization is reflected as a fracture zone often composed of two or more sulphide-quartz lodes and stringers. Thickness of the mineralized zones range from 0.5 m to 4.4 m. It has been diluted during modelling to reflect a minimum mining height of 1.8 m.
- The Joe Mann deposit is characterized by east-west striking shear hosted lodes that extend beyond 1,000 m vertically with mineralization identified over a 3 km strike length. These shear zones form part of the Opawica-Guercheville deformation zone, a major deformation corridor cutting the mafic volcanic rocks of the Obatogamau Formation in the north part of the Caopatina Segment. The gabbro sill hosts the Main Zone and the West Zone at the mine, while the South Zone is found in the rhyolite. These three subvertical E-W (N275°/85°) ductile-brittle shear zones are sub-parallel to stratigraphy and to one another, with up to 140 m to 170 m of separation between them. These shear zones are hosted within a stratigraphic package composed of iron-magnesium (Fe-Mg) carbonate and sericite altered gabbro sills, sheared basalts, and intermediate to felsic tuffs intruded by various felsic intrusions. The Joe Mann gold mineralization is hosted by decimetre scale quartz-carbonate lodes (Dion and Guha 1988). The lodes are mineralized with pyrite, pyrrhotite, and chalcopyrite disposed in lens and lodelets parallel to schistosity, and occasionally visible gold. There are some other minor, mineralized structures, e.g., North and South-South Zones, with limited vertical and horizontal extensions.

| Drill hole Information | 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:
- easting and northing of the drill hole collar
- elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
- dip and azimuth of the hole
- down hole length and interception depth
- 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. | - All requisite drillhole information is tabulated elsewhere in this release. Refer Appendix A of the body text
|
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. | - All drill hole intersections are reported above a lower cut-off grade of 0.5% copper.
|
| 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. | - A maximum of 1m internal waste was allowed
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. | - No metal equivalents reported
|
| Relationship between mineralisation widths and intercept lengths | These relationships are particularly important in the reporting of Exploration Results.
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'). | - All intersections reported in the body of this release are down hole.
- The majority of the drill holes in the database are drilled as close to orthogonal to the plane of the mineralized lodes as possible.
- Only down hole lengths are reported.
|
| 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. | - Included elsewhere in this release. Refer figures in the body 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. | - All results greater than 0.5% Cu and 0.5g/t Au have been reported at greater than 1m width
|
| 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. | - Appropriate plans are included in the body of this release.
|
| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out 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. | - The Company will be conducting drill testing of additional mineralisation as well as step out drilling of existing lodes to further enhance the resources quoted in this release. More information is presented in the body of this report.
- Diagrams in the main body of this release show areas of possible resource extension on existing lodes. The company continues to identify and assess multiple other target areas within the property boundary for additional resources.
