“Importantly, it comes at a time of rising demand for copper initiatives in engaging jurisdictions with actual scale and a transparent pathway to manufacturing and cashflow. With this elevated useful resource base, and the continued development outlook, Cygnus is now clearly in that league.
“Having the ability to ship a brand-new useful resource at Golden Eye in such a brief area of time speaks volumes. It shouldn’t be misplaced that our complete gold sources have elevated considerably in a gold value surroundings in extra of US$3,500/oz.
“Given the possibly important advantages of the elevated useful resource on a manufacturing profile and the sharp rises in our commodity costs for the reason that earlier research performed three years in the past, the sights of the Chibougamau Undertaking at the moment are very clear to us.”
TORONTO and PERTH, Australia, Sept. 16, 2025 (GLOBE NEWSWIRE) — Cygnus Metals Restricted (ASX: CY5; TSXV: CYG; OTCQB: CYGGF) (“Cygnus” or the “Firm”) is happy to announce a MRE replace for the Chibougamau Copper-Gold Undertaking in Quebec (Desk 1).
This up to date MRE is comprised of:
- 6.4 Mt at 3.0% CuEq (2.3% Cu, 0.8 g/t Au, 7.6 g/t Ag) for 193 kt CuEq (149 kt Cu, 167 koz Au, and 1.6 Moz Ag) or 4.3 g/t AuEq for 884 koz AuEq within the Measured and Indicated classes; and
- 8.5 Mt at 3.5% CuEq (2.1% Cu, 1.7 g/t Au, 7.9 g/t Ag) for 295 kt CuEq (182 kt Cu, 454 koz Au, 2.2 Moz Ag) or 4.8 g/t AuEq for 1.3 Moz AuEq within the Inferred class.
Total, this ends in a major improve within the complete useful resource base for the Chibougamau Hub and Spoke Undertaking.
The MRE replace for the Chibougamau Undertaking contains the Nook Bay, Cedar Bay, Joe Mann, and Devlin deposits and the brand new Golden Eye deposit, all positioned inside a 60 km radius from Cygnus’ 100%-owned current processing facility. The rise within the MRE is the results of drilling applications accomplished by Doré Copper in 2022 & 2024 at Nook Bay and Cygnus in 2025 at Nook Bay and Golden Eye. Within the 9 months since Cygnus acquired Doré Copper on 1 January 2025, Cygnus has accomplished 17,183 m of drilling.
A significant a part of the elevated MRE is because of a profitable exploration drilling marketing campaign at Golden Eye which was a spotlight of early goal technology and exploration work by the Cygnus exploration crew. The preliminary useful resource at Golden Eye contains Indicated Mineral Sources of 91 koz at 5.6 g/t AuEq and Inferred Mineral Sources of 182 koz at 4.6 g/t AuEq. The Firm sees additional alternative to develop this useful resource, which stays open at depth beneath 400 m and in a number of instructions.
The rise within the world MRE (see Determine 1) in a brief timeframe proves that important development alternatives exist on the Chibougamau Undertaking. Diamond drill rigs are persevering with to show whereas the Firm continues to execute its in-house AI pushed resolution for the compilation of historic drill logs and maps, a few of which have by no means been seen in fashionable 3D software program. This background work has efficiently assisted Cygnus in focusing on Golden Eye and resulted within the supply of an preliminary MRE, in addition to figuring out new drill targets at Cedar Bay (presently being drilled), and shall be basic to producing extra drill targets throughout the camp.

SUMMARY OF THE RESOURCE PARAMETERS
In accordance with ASX Itemizing Rule 5.8.1, a good and balanced illustration of the data contained in JORC Desk 1 (refer Appendix B), together with a abstract of all data materials to understanding the reported MRE is offered beneath.
Undertaking Geology and Geological Interpretation
Regional and Native Geology
The Undertaking is positioned on the northeastern extremity of the Abitibi Sub province within the Superior province of the Canadian Protect. The Abitibi Sub-province is taken into account to be one of many largest and best-preserved greenstone belts on the earth and hosts quite a few gold and base metallic deposits.
The Chibougamau area is positioned within the northeastern a part of the Abitibi Greenstone Belt of the Superior Province. The Archean rocks of the Chibougamau area had been deformed and metamorphosed from greenschist to amphibolite facies through the Kenoran orogeny.
The Chapais-Chibougamau space recorded main intrusive actions of varied nature, genetically linked to the volcanism and tectonism durations of the geological historical past of the area. The three necessary intrusive our bodies of the area are: 1) the Doré Lake Advanced (“DLC”); 2) the Chibougamau Pluton; and three) the differentiated mafic to ultramafic sills of the Cumming Advanced that shaped within the second volcanic cycle.
The DLC hosts the Nook Bay, Cedar Bay and Golden Eye deposits in addition to a number of different regional copper-gold deposits. It dates to 2,728.3 ± 1.2 Ma (Mortensen, 1993) and is a synvolcanic layered intrusion emplaced through the first volcanic cycle within the area between the Obatogamau and Waconichi Formations. DLC is an anorthositic complicated with mafic to ultramafic intrusions with a tholeiitic to calc-alkaline magmatic affinity (Allard, 1976; Daigneault and al., 1990; Ahmadou and al., 2019).
The Chibougamau Pluton hosts the Devlin deposit. The pluton was emplaced within the DLC and a part of the Waconichi Formation; nonetheless, it’s coeval with the second volcanic cycle of the Roy Group. The Chibougamau Pluton consists of an abundance of tonalite and diorite dikes, pegmatites, feldspar-phyric models, in addition to hydrothermal and magmatic breccia; all of which level to a shallow emplacement depth (Mathieu and Racicot, 2019). The pluton occupies the core of the Chibougamau anticline, which is a part of the foremost folding buildings of the area.
The Joe Mann deposit is a structurally managed deposit hosted by the Opawica-Guercheville deformation zone. This main east-west trending deformation hall is roughly 2km large and extends for over 200km (Tait, 1992a; Pilote 1998; Leclerc et al. 2012). The construction cuts the mafic volcanic rocks of the Obatogamau Formation within the north a part of the Caopatina Phase.
Mineralization
The Nook Bay, Cedar Bay and Golden Eye deposits are positioned on the flanks of the DLC. These deposits are typical shear hosted copper-gold veins located throughout the host anorthosite which is sheared and sericitized over widths of two m to 25 m. The mineralization is characterised by veins and/or lenses of large to semi-massive sulphides related to a brecciated to regionally large quartz-calcite materials. The sulphides assemblage consists of chalcopyrite, pyrite, and pyrrhotite, with lesser quantities of molybdenite and sphalerite. Late remobilized quartz-chalcopyrite-pyrite veins happen in a standard large halo round the principle mineralization zones.
The Devlin deposit is hosted within the Chibougamau Pluton and is characterised by flat-lying undulating magmatic large sulphide veins occurring at a depth of lower than 100 m from floor. The deposit is hosted by a hydrothermal breccia, consisting of large chalcopyrite-pyrite-quartz +/- carbonate vein, which pinches and swells. Minor hematite and magnetite are current regionally; each being erratically distributed.
The gold mineralization on the Joe Mann mine is hosted by decimetre scale quartz-carbonate veins. The veins are mineralized with pyrite, pyrrhotite, and chalcopyrite disposed in lens and veinlets parallel to schistosity, and sometimes seen gold. The veins are dominated by vitreous white quartz with minor plagioclase and iron carbonate. They’re intensely brecciated and sometimes boudinaged and folded. Moreover, these veins are characterised by their laminated or banded construction, consisting of alternating ribbons of quartz and mineralized wall rock. The vast majority of the vein sulphide mineralization is contained in these wall-rock fragments.
Drilling and Sampling Strategies
Drilling on the Chibougamau Undertaking has been carried out solely by diamond drilling. A complete of 768 drill holes for a complete of 308,314 m have been included for the needs of the MRE. The distribution of drilling by deposit is summarised beneath.
| Deposit | Holes | Metres |
| Nook Bay | 403 | 207,920 |
| Cedar Bay | 37 | 33,360 |
| Joe Mann | 51 | 17,622 |
| Devlin | 176 | 19,112 |
| Golden Eye | 101 | 30,300 |
| Complete | 768 | 308,314 |
All 35 holes for 17,183 m of diamond drilling accomplished by Cygnus had been NQ2 (50.6 mm diameter) and surveyed utilizing DeviGyro OX NQsupplied by IMDEX out of Val-d’Or, Québec.
Cygnus established a sampling protocol whereby core is often sampled to a most size of 1 metre and a minimal of 0.3 m to accommodate geological boundaries or modifications in mineralization. Whereas this protocol was adopted for present drilling, some historic drill holes embrace intervals shorter than 0.3 m or longer than 1 m.. All Cygnus core was lower in half, with the non-assayed portion saved for future reference if required.
For additional element relating to drilling and sampling, please check with Appendix B (Desk 1 – Part 1).
Pattern Evaluation Technique
All assays accomplished by Cygnus had been carried out by Bureau Veritas Commodities Canada Ltd (“BV”). Pattern preparation and hearth assay evaluation had been performed at BV in Timmins, Ontario, and ICP-ES multi-elements evaluation was performed at BV in Vancouver, B.C.
Samples had been weighed, dried, crushed to 70% passing 2 mm, break up to 250 g, and pulverized to 85% passing 75 µm. Samples are hearth assayed for gold (Au) (50 g and 30 g) and multi-acid digestion ICP-ES end, for 23 components (together with key components Ag, Cu, Mo). Samples with seen gold or more likely to have gold grains are analysed with metallic display hearth assay. Samples assaying >10.0 g/t Au are re-analysed with a gravimetric end utilizing a 50 g and 30 g cost. Samples assaying >10% Cu are re-analysed with a sodium peroxide fusion with ICP-ES evaluation utilizing a 0.25 g cost.
QA/QC is completed in-house by Cygnus’ geologists with oversight from the Senior Geologist. The examine samples (blanks and requirements – 4% of complete samples with one other 2% of core duplicates taken on half break up core) that had been inserted into the pattern batches are verified in opposition to their licensed values and are deemed a move if they’re inside 3 normal deviations of the licensed worth. The duplicates are evaluated in opposition to one another to find out mineralization distribution (nugget). If there are massive discrepancies within the examine samples, then your complete batch is requested to be re-assayed.
For additional particulars relating to drilling and sampling, please check with Appendix B (Desk 1 – Part 1).
Estimation Methodology
Geological and mineralisation constraints had been generated in Leapfrog by Cygnus employees, reviewed by the Competent Individual, and utilized to geostatistics, variography, block modelling, and grade interpolation. Tasks usually are not operational, and outcomes haven’t been validated in opposition to reconciliation information. Submit-mineralisation dykes and overburden had been assigned zero grade. Guardian block sizes had been sub-celled and, the place acceptable, rotated. Block mannequin validation used normal business strategies, together with visible inspection, statistical comparability (ID, NN, OK), swath plots, and wireframe-to-block quantity checks. No assumptions had been made about correlations between variables.
Grade interpolation adopted inverse distance strategies (ID² or ID³) with progressively bigger search passes. Search ellipses had been anisotropic or isotropic relying on the deposit, oriented utilizing dynamic anisotropy or the default coordinate system. Assay capping was utilized utilizing primary statistics, histograms, log likelihood plots, and decile evaluation, with composites typically shaped at both 2 m or full-width intercepts.
Nook Bay contains 9 domains (CBAD1 to CBAD4, CBAD3a, CBUD, WV, WV2, WV3) constructed utilizing a 1% CuEq cut-off and a 2 m minimal thickness. Guardian blocks are 5×5×5 m, sub-celled to 1.25×0.625×1.25 m, and rotated 5°. Capping ranges are 16% for Cu, 5 g/t for Au, and 80 g/t for Ag. The composites are 2 m lengths, besides full width for CBUD.
Cedar Bay has 4 domains primarily based on a 1% CuEq cut-off and roughly a 1.5 m minimal thickness. Guardian blocks are 5×5×5m, sub-celled to 1.25 m. Capping ranges are 40 g/t for Au, 12% for Cu, and 60 g/t for Ag. Composites are full width.
Joe Mann has three domains with a 2 g/t Au cut-off and 1.2 m minimal thickness. Capping ranges are 45 g/t for Au, and a pair of.5% for Cu, with high-grade restrictions of 20 g/t Au over 18.75 m within the x-axis and 75 m within the y-axis of the second interpolation move. Guardian blocks are 5×1×5 m, sub-celled to 1.25×0.25×1.25 m in two block fashions with completely different rotations. Composites are full width.
Devlin has 4 domains (three higher, one decrease) primarily based on a 1% Cu cut-off and a 1.8 m minimal thickness. Capping ranges are 2.5 g/t for Au and 15% for Cu within the Decrease Zone and 1.5 g/t for Au and 10% for Cu within the Higher Zone. Guardian blocks are 10×10×2.5 m, sub-celled to five×5×1.25 m. Composites are full width.
Golden Eye has ten domains primarily based on a 1% CuEq cut-off and a 1.5 m minimal thickness. Guardian blocks are 5×5×5 m, sub-celled to 1.25 m. Capping ranges are 40 g/t for Au, 12% for Cu, and 60 g/t for Ag. Composites are full width.
Bulk Density
At Nook Bay, 1,667 water immersion density measurements had been collected. Mineralisation domains ranged from 2.85 g/cm³ to three.02 g/cm³, whereas overburden was assigned 2.0 g/cm³.
| Nook Bay Density Domains | Density (g/cm³) | Domains | Density (g/cm³) |
| Overburden | 2.00 | WV | 2.86 |
| CBAD1 | 3.02 | WV2 | 2.85 |
| CBAD2 | 3.02 | WV3 | 2.93 |
| CBAD3 | 3.00 | CBAD4 | 2.95 |
| CBUD | 2.97 | CBAD3a | 2.90 |
| Adjoining Materials | 2.90 |
At Cedar Bay, 23 density measurements from two drill holes gave a mean of two.90 g/cm³, utilized to all mineralised blocks.
At Joe Mann, 603 density measurements (2020–2021) ranged from 2.78 g/cm³ to three.07 g/cm³ in mineralization and 1.28 g/cm³ to three.24 g/cm³ in adjoining materials; 2.90 g/cm³ was assigned to mineralization.
At Devlin, 52 samples (2013–2014) averaged 2.87 g/cm³; densities had been set at 2.90 g/cm³ (Decrease Zone), 2.85 g/cm³ (Higher Zone), and a pair of.77 g/cm³ (background).
At Golden Eye, just like Cedar Bay, 2.90 t/m³ was assigned to mineralised blocks, in line with host rock and restricted density information.
It’s the Competent Individual’s opinion that except a small variety of outliers, these are affordable densities for these kind of mineralization and host rocks.

Boundaries had been adjusted for geological understanding, copper grade continuity, and cohesion, with some lower-grade materials included.
At Joe Mann, solely Inferred Mineral Sources are outlined as a consequence of wider drill spacing (20 m to 100 m) and in consideration of noticed grade continuity and variability primarily based on historic mining. Decrease-grade materials was included within the Main01 wireframe design to protect continuity.
Mining Components
The anticipated mining methodology for sub-vertical dipping deposits: Nook Bay, Cedar Bay, Golden Eye and Joe Man is longitudinal lengthy gap with pillar (“LHP”). This mining methodology has been used to establish smart SMU models when figuring out block sizes within the mannequin.
The anticipated mining methodology for Devlin is both 1) drift and fill with slash; and a pair of) room and pillar with partial pillar restoration.
SLR ready underground reporting shapes from indicator shells constructed on the respective deposit breakeven cut-off grade for Mineral Useful resource reporting. Some incremental materials throughout the shapes was included to protect continuity. Minimal thickness was thought-about and utilized on the wireframing stage.
Sources are calculated as in-situ sources. Conservative elements used to calculate the underground reporting cut-off are primarily based on earlier working price foundation for the mill, recoveries and common and administration (G&A) prices and metallic costs beneath:
- Alternate Price US$1.00 = C$1.35
- Metallic Value Copper: US$9,370/t
- Metallic Value Gold: US$2,400/oz

- Nook Bay
- CuEq(%) = Cu(%) + (Au(g/t) x 0.68919) + (Ag(g/t) x 0.00884)
- AuEq (g/t) = Au(g/t) + (Cu(%) x 1.45097) + (Ag(g/t) x 0.01282)
- Cedar Bay
- CuEq(%) = Cu(%) + (Au(g/t) x 0.78730) + (Ag(g/t) x 0.00905)
- AuEq (g/t) = Au(g/t) + (Cu(%) x 1.27016) + (Ag(g/t) x 0.01149)
- Devlin
- CuEq(%) = Cu(%) + (Au(g/t) x 0.62517) + (Ag(g/t) x 0.00862)
- AuEq (g/t) = Au(g/t) + (Cu(%) x 1.59957) + (Ag(g/t) x 0.01379)
- Golden Eye
- CuEq(%) = Cu(%) + (Au(g/t) x 0.78730) + (Ag(g/t) x 0.00905)
- AuEq (g/t) = Au(g/t) + (Cu(%) x 1.27016) + (Ag(g/t) x 0.01149)
- Joe Mann
- CuEq(%) = Cu(%) + (Au(g/t) x 0.72774)
- AuEq (g/t) = Au(g/t) + (Cu(%) x 1.37411)
It’s the Firm’s view that every one components within the metallic equal calculations have an affordable potential to be recovered and bought.
Reporting Reduce-Off Values
The next copper equal (CuEq) and gold equal (AuEq) cut-off values have been utilized for reporting:
- 1.2% CuEq for Nook Bay
- 1.5% CuEq for Devlin
- 1.8 g/t AuEq for Cedar Bay and Golden Eye
- 2.0 g/t Au Eq for Joe Mann
