Chibougamau Copper-Gold Project, Canada

Two diamond drill rigs about to arrive on site as part of strategy to grow the resource and test brownfield exploration targets

HIGHLIGHTS:

• Cygnus has secured additional ground next to its Chibougamau Copper-Gold Project, increasing its total land holding to 282km2

• The newly staked areas add to a highly prospective land position which has seen limited modern exploration in the past 20 years
• Chibougamau Copper-Gold Project has a Measured and Indicated Mineral Resource of 3.6Mt at 3.0% CuEq and an Inferred Mineral Resource of 7.2Mt at 3.8% CuEq1
• The Chibougamau district is a world-class mineral terrane with strong potential for additional discovery; Historical production totals more than 945,000t of copper and 3.5Moz of gold across 16 former producing mines2
• Two diamond drill rigs are set to start this week, targeting both resource growth and priority brownfield exploration targets, underpinning strong news flow
• Drilling results are expected imminently from a targeted exploration program completed prior to Cygnus' merger with Doré Copper Mining Corp. (see ASX release dated 2 January 2025)
• The Chibougamau Copper-Gold Project includes a 900,000tpa processing facility – the only milling infrastructure within a 250km radius
• The district also has excellent infrastructure with a local mining town, a modern mining workforce training centre, sealed highway, airport, regional rail infrastructure and 25kV hydro power to the processing site

Cygnus Executive Chairman, David Southam said: "Our immediate strategy is to create value through exploration at Chibougamau and we are wasting no time executing this aspect of our plan.

"Expanding our ground position increases the upside at the project and reflects our strong belief in the immense exploration and resource growth potential.

"All of this newly staked land is adjacent to the high-grade Chibougamau mining camp which has an incredible production record dating back over 65 years, producing almost 1 million tonnes of copper and 3.5 million ounces of gold".

TORONTO, Jan. 08, 2025 (GLOBE NEWSWIRE) -- Cygnus Metals Limited (ASX: CY5; TSXV: CYG) ("Cygnus" or the "Company") is pleased to announce that it has expanded its land holding by 50 per cent at the Chibougamau Copper-Gold Project in Quebec, Canada and is about to start drilling.

Cygnus recently completed its transformative merger with Doré Copper Mining Corporation, creating a new leading player in the critical minerals sector with a strategic focus on high-grade copper and lithium assets in Quebec, Canada. A key motivation behind the merger was to advance the Chibougamau Copper-Gold Project which has established high-grade mineral resources of:

Measured and Indicated Mineral Resources of 3.6Mt at 3.0% CuEq and Inferred Mineral Resources of 7.2Mt at 3.8% CuEq (refer to Appendix A)1

The multi-pronged value creation strategy has a strong focus on resource growth and brownfield exploration with significant potential for additional discovery in the region. Part of that strategy was to bolster the ground position and provide additional exploration opportunity in a world-class mineral terrane that has historically produced nearly 1Mt of copper and 3.5Moz of gold over a 65 year history.2 This large and well-endowed mineral system is driven by the central Chibougamau Pluton with the recently acquired ground adding more of this highly prospective geology to the combined project.

The new claims have been acquired at minimal cost to Cygnus, being newly staked and open ground immediately surrounding the existing project, and are principally in the anorthosite band that surrounds the Chibougamau Pluton, which typically host mineral deposits in the Chibougamau mining camp. In total, 174 claims have been staked for 97km2 taking the combined Chibougamau Copper-Gold Project to 282km2. This provides an excellent platform to drive growth through exploration in a highly prospective district.

In line with the Company's resource growth strategy, drilling is about to start 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 Chibougamau Copper-Gold Project

The 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 Project is centred on the Chibougamau Pluton with historic production in the Chibougamau mining district of 53.5Mt @ 3.4% CuEq2 from periodic mining between the early 1900s and 2008. Over this long mining history, the district has produced nearly 1Mt of copper and 3.5Moz of gold from 16 former producing mines.2

The Project has high-grade resources including Measured and Indicated Mineral Resources of 3.6Mt at 3.0% CuEq and Inferred Mineral Resources of 7.2Mt at 3.8% CuEq with significant potential to grow (refer to Appendix A).1

The Company has a clear strategy to:

• Grow the current resource through brownfield exploration and investment in drilling, modern geophysics and other exploration activities
• Advance the project towards development through study work and utilising existing infrastructure

The Company sees substantial 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 A – Chibougamau Copper-Gold Project – Foreign Estimate Disclosures as at 30 March 2022

Notes:

1. Cygnus Metals Ltd cautions that Mineral Resources for the Chibougamau Copper Project, incorporating Corner Bay, Devlin, Cedar Bay and Joe Mann, are reported in accordance with the requirements applying to foreign estimates in the ASX Listing Rules and, as such, are not reported in accordance with the JORC Code (2012 Edition). A Competent Person has not yet completed sufficient work to classify the resources as Mineral Resources that satisfy the guidelines provided in the JORC Code (2012 Edition). It is uncertain that following evaluation and/or further exploration work that the Mineral Resources will be able to be reported as Mineral Resources in accordance with the JORC Code (2012 Edition).
2. All resources have been prepared in accordance with CIM Standards. Please refer to Cygnus' announcement on 15 October 2024 for additional technical information relating to the foreign estimate.
3. The Mineral Resource estimates include Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorised as Mineral Reserves. There is also no certainty that Inferred Mineral Resources will be converted to Measured and Indicated categories through further drilling, or into Mineral Reserves once economic considerations are applied.
4. Numbers may not reconcile precisely due to rounding.
5. Mineral resources have been reported at a cut-off grades of 2.6 g/t Au at Joe Mann, 1.3% Cu at Corner Bay, 2.9 g/t Au at Cedar Bay and 1.2% Cu at Devlin. Mineral Resources at Joe Mann are estimated using a long-term gold price of US$1,800/oz Au, and a metallurgical gold recovery of 83%. Mineral Resources at Corner Bay and Devlin are estimated using a long-term copper price of US$3.75 per pound, and a metallurgical copper recovery of 95%. Mineral Resources at Cedar Bay are estimated using a long-term gold price of US$1,400/oz Au, and a metallurgical gold recovery of 90%.
6. Metal equivalents for the foreign estimate have been calculated at a copper price of US$8,300/t, gold price of US$2,000/oz, silver price of US$25/oz and zinc price of $2,500/t. Copper equivalent was calculated based on the formula CuEq (%) = Cu(%) + (Au (g/t) x 0.77472) + (Ag (g/t) x 0.00968) + (Zn (%) x 0.3012). Metallurgical recovery factors have not been applied at this time to copper equivalents calculation due to variance of geology within the camp and lack of available data. It is the Company's view that all elements in the copper equivalent calculations have a reasonable potential to be recovered and sold.
   

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.
