• Golden Eye has never been mined and was last drilled in the early 1990s when gold was less than US$350/oz. The entire drilling target sits outside the current Mineral Resource¹
• Importantly Golden Eye remains open at depth with 2.9m @ 10.2g/t AuEq in deepest hole from recent campaign³
• The Golden Eye prospect sits 3km from Cygnus’ central processing plant and has existing dual ramp access within 150m of the mineralisation
• Gold was a significant part of the historic production within the Chibougamau District, with over 3.5Moz of gold produced alongside 945,000t of copper.⁴

Cygnus Metals Limited (ASX: CY5) (TSX-V: CYG) (OTCQB: CYGGF) is pleased to announce further high-grade assays from the Golden Eye prospect within the Chibougamau Copper-Gold Project in Quebec.

Recent results from two diamond holes have revealed the presence of multiple parallel mineralised zones with gold-copper-silver mineralisation. The results from the latest assays include:

• 3.3m @ 3.8g/t AuEq from 174.2m (3.2g/t Au, 0.4% Cu & 3.5g/t Ag) (LDR-25-09);
• 3.3m @ 12.7g/t AuEq from 209.6m (8.4g/t Au, 3.1% Cu & 30.2g/t Ag) (LDR-25-09);
  • Including 1.9m @ 21.1g/t AuEq (14.2g/t Au, 4.9% Cu & 47.5g/t Ag);
• 2.5m @ 7.3g/t AuEq from 226.5m (5.9g/t Au, 0.9% Cu & 14.9g/t Ag) (LDR-25-09);
• 2.7m @ 3.5g/t AuEq from 147.7m (1.5g/t Au, 1.3% Cu & 23.0g/t Ag) (LDR-25-10); and
• 4.3m @ 9.8g/t AuEq from 157.8m (7.5g/t Au, 1.6% Cu & 23.9g/t Ag) (LDR-25-10);
  • Including 2.0m @ 18.8g/t AuEq (14.6g/t Au, 2.8% Cu & 43.5g/t Ag).

These results are in addition to previously released results^2,3 from Golden Eye:

• 3.3m @ 6.6g/t Au from 131.7m (LDR-25-05);
  • Including 2.3m @ 9.1g/t Au;
• 7.4m @ 5.7g/t AuEq (4.6g/t Au, 0.9% Cu & 5.6g/t Ag) from 405.6m (LDR-25-08); and
  • Including 3.1m @ 9.6g/t AuEq (7.4 g/t Au, 1.6% Cu & 10.0g/t Ag);
• 2.9m @ 10.2g/t AuEq (8.3g/t Au, 1.4% Cu & 3.3g/t Ag) from 463.8m (LDR-25-08);
  • Including 0.4m @ 60.8g/t AuEq (51.3g/t Au, 7.2% Cu & 18.0g/t Au).

With the drilling at Golden Eye completed and the majority of assays returned (assays are pending for one hole), the focus has shifted towards establishing an initial resource for Golden Eye. This will include the six holes for 1,954m completed this year as well as the compiled historic data which includes 77 holes for 21,371m. Significant historic drill intercepts² dating back to the 1990s returned:

• 5.9m @ 34.1g/t AuEq (32.2g/t Au, 1.2% Cu & 27.3g/t Ag) (RD-11);
• 4.5m @ 21.6g/t AuEq (14.9g/t Au, 4.7% Cu & 54g/t Ag) (RD-28);
• 8.4m @ 12.7g/t AuEq (11.0g/t Au, 1.3% Cu & 15.8g/t Ag) (RD-20);
• 7.5m @ 22.1g/t AuEq (16.0g/t Au & 4.7% Cu) (S1-87-1); and
• 10.4m @ 12.2 g/t AuEq (7.3g/t Au, 3.5% Cu & 31.8g/t Ag) (S3-86-4).

Defining a new resource at Golden Eye, with its existing double ramp access as well as being located within 3km of the 100%-owned 900,000tpa central processing facility, is a significant head start down the development pathway of the project. With this infrastructure already in place alongside the near surface high-grade mineralisation with significant gold as well as copper and silver, there is significant scope to enhance future mining studies. Importantly, Golden Eye remains open at depth and has only been drilled to 400m below surface with deepest drilling from the current campaign returning 2.9m @ 10.2g/t AuEq from 463.8m in LDR-25-08. Exploration drilling is being planned at depth to extend mineralisation and further enhance the pending resource.

Cygnus will continue to focus on resource growth and build upon the current high-grade copper-gold resources through low-risk brownfield exploration across the camp. This work includes ongoing compilation of historic data, with Golden Eye an excellent example of the value generated through this work which is helping to unlock this historic district.

Ongoing Work

Cygnus is continuing to compile the data across the camp and deliver additional drill targets as the Company looks to execute its strategy of value creation through resource growth and conversion drilling. This low-cost, low-risk approach includes both surface and downhole electromagnetics to generate brownfield targets around known high quality mineralisation.
