Cygnus targets resource growth with start of new drilling and geophysics programs

Chibougamau Copper-Gold Project, Canada

HIGHLIGHTS:

• Cygnus sets up value drivers for 2026 with exploration and resource growth a high priority
• At Cedar Bay, Downhole Electromagnetics (‘DHEM’) is in progress to identify follow-up targets from recent intersections¹ such as:
  • 28.9m at 2.5g/t AuEq (1.0g/t Au, 1.0% Cu & 12.0g/t Ag) (CDR-25-16)
  • 10.6m at 4.1g/t AuEq (3.6g/t Au, 0.3% Cu & 2.8g/t Ag) (CDR-25-11W1)
• This is the first time DHEM is being used at Cedar Bay in over 20 years
• Drilling has started at Golden Eye to test extensions below the current resource, which stands at 0.5Mt at 5.6g/t AuEq for 91koz AuEq (Indicated) and 1.2Mt at 4.6g/t AuEq for 182koz AuEq (Inferred)²
• At Joe Mann, a detailed Induced Polarisation (‘IP’) survey is underway to identify walk-up drill targets analogous to IAMGOLD’s Nelligan Complex deposits which contain 4.3Moz Au (M&I) and 7.5Moz Au (Inferred)³ located just 10km west of Joe Mann
• Permits are being submitted for the Gwillim prospect for drilling in the coming quarter; This will co-funded by 50% JV partner Alamos Gold, which has a market capitalisation of ~C$25B. Initial targets will follow up historic intersections⁴ of:
  • 7.6m @ 38.1g/t Au from 314.9m (87-KOD-18);
  • 15.2m @ 9.4g/t Au from 155.1m (87-KOD-1); and
  • 16.4m @ 8.3g/t Au from 168.3m (87-KOD-10).
• Cygnus believes there is significant potential to continue growing the Chibougamau resource, which stands at 6.4Mt at 3% CuEq for 193kt CuEq (M&I) and 8.5Mt at 3.5% CuEq for 295kt CuEq (Inferred)2

Cygnus Metals Limited (ASX: CY5; TSXV: CYG,OTC:CYGGF; OTCQB: CYGGF) (‘Cygnus’ or the ‘Company’) is pleased to announce the start of extensive exploration programs aimed at growing the resources at its Chibougamau Copper-Gold Project in Quebec.

Resource growth and discovery remain a key pillar of Cygnus’ growth strategy as the Company continues to unlock the Chibougamau district. A key focus is brownfields exploration, including extensions to deposits such as Cedar Bay and Golden Eye.

At Cedar Bay, Downhole Electromagnetics (‘DHEM’) is in progress to define follow up drill targets from recent exploration drilling¹ which returned:

• 28.9m at 2.5g/t AuEq (1.0g/t Au, 1.0% Cu & 12.0g/t Ag) (CDR-25-16)
• 10.6m at 4.1g/t AuEq (3.6g/t Au, 0.3% Cu & 2.8g/t Ag) (CDR-25-11W1)

Recent drilling successfully demonstrated extensions to the current resource at Cedar Bay of 0.3Mt at 8.1g/t AuEq for 67koz (M&I) and 0.8Mt at 7.8g/t AuEq for 205koz (Inferred).² DHEM aims to define resource extensions as well as identifying high grade shoots which are typically associated with semi massive sulphides. This will be the first time DHEM is being used at Cedar Bay in over 20 years, presenting a huge opportunity for Cygnus.

At Golden Eye, drilling has commenced with three rigs to grow the Indicated Resource and extend the resource below the currently defined depth of just 450m. Golden Eye was a new resource defined by Cygnus last year of 0.5Mt at 5.6g/t AuEq for 91koz (Indicated) and of 1.2Mt at 4.6g/t AuEq for 182koz (Inferred)² and remains open at depth with one of the deepest intersections⁵ from last year of:

• 2.9m @ 10.2g/t AuEq (8.3g/t Au, 1.4% Cu & 3.3g/t Ag) from 463.8m (LDR-25-08)

The Company also has a strong focus on defining new resources and making discoveries. Two key areas identified as high priority are gold targets Joe Mann and Gwillim.

At Joe Mann, the Company has commenced a detailed Induced Polarisation (‘IP’) survey along major structures to identify walk-up drill targets for Q2 this year. Cygnus is targeting analogous mineralisation to IAMGOLD’s Nelligan Complex, which is located just 10km west of the project and contains 4.3Moz Au (M&I) and 7.5Moz Au (Inferred).³

This survey will help to generate further drill targets in addition to some of the high-grade historic intersections which also require follow up.⁴ These include:

• 0.7m @ 480.2g/t Au from 92.3m (H-118);
• 3.8m @ 20.8g/t Au from 287.2m (H-214); and
• 8.4m @ 6.3g/t Au from 175.6m (H-374).

At Gwillim, permits are underway for drilling to commence in the coming quarter. Drilling at Gwillim will be co-funded by 50% JV partner Alamos Gold, which has a market capitalisation of ~C$25B. Gwillim is just 12km from the Chibougamau processing facility and has high potential for defining new resources. Initial drilling will focus on following up high-grade historic intersections⁴ such as:

• 7.6m @ 38.1g/t Au from 314.9m (87-KOD-18);
• 15.2m @ 9.4g/t Au from 155.1m (87-KOD-1); and
• 16.4m @ 8.3g/t Au from 168.3m (87-KOD-10).

The Chibougamau area has well-established infrastructure, giving the Project a significant headstart as a copper-gold development opportunity. This infrastructure includes a 900,000tpa processing facility, local mining town, sealed highway, airport, regional rail infrastructure and 25kV hydro power to the processing site. Significantly, the Chibougamau processing facility is the only processing facility within a 250km radius.

APPENDIX A – Mineral Resource Estimate for the Chibougamau Project as at 17 September 2025

Notes:

1. Cygnus’ Mineral Resource Estimate for the Chibougamau Copper-Gold project, incorporating the Corner Bay, Devlin, Joe Mann, Cedar Bay, and Golden Eye deposits, is reported in accordance with the JORC Code and the Canadian Institute of Mining, Metallurgy and Petroleum (‘CIM’) (2014) definitions in NI 43-101.
2. Mineral Resources are estimated using a long-term copper price of US$9,370/t, gold price of US$2,400/oz, and silver price of US$30/oz, and a US$/C$ exchange rate of 1:1.35.
3. Mineral Resources are estimated at a CuEq cut-off grade of 1.2% for Corner Bay and 1.5% CuEq for Devlin. A cut-off grade of 1.8 g/t AuEq was used for Cedar Bay and Golden Eye; and 2.0 g/t AuEq for Joe Mann.
4. Corner Bay bulk density varies from 2.85 tonnes per cubic metre (t/m³) to 3.02t/m³ for the estimation domains and 2.0 t/m³ for the overburden. At Devlin, bulk density varies from 2.85 t/m³ to 2.90 t/m³. Cedar Bay, Golden Eye, and Joe Mann use a bulk density of 2.90 t/m³ for the estimation domains.
5. Assumed metallurgical recoveries are as follows: Corner Bay copper is 93%, gold is 78%, and silver is 80%; Devlin copper is 96%, gold is 73%, and silver is 80%; Joe Mann copper is 95%, gold is 84%, and silver is 80%; and Cedar Bay and Golden Eye copper is 91%, gold is 87%, and silver is 80%.
