AURYN Mining Corporation Shareholder Update

AURYN Mining Corporation (OTC: AUMC) is committed to keeping our shareholders informed with the most current updates on our progress and strategic initiatives. As we enter the second quarter of 2025, we share the following updates and forward-looking approach to our mining and exploration activities.

ACCOMPLISHMENTS

Operations and Plan Development

During this quarter, we significantly advanced activities at our Fortuna site:

  • Antonino Tunnel Operations: We retained a specialized contractor who is managing Antonino Tunnel operations as part of the La Fortuna Sub-Level Stoping Project. Current efforts include enhancing tunnel access, improving grade, and ensuring continuous, efficient operations with minimal disruptions.
  • We are advancing two additional exploitation projects targeting the Merlin IV vein, both in its northern and southern extensions. Each project targets an extraction rate of 1,000 tons of ore monthly, bringing our total authorized production capacity to 3,000 tons per month by the third quarter of 2025.
  • Site preparation, including clearing and leveling for our Mineral Flotation Plant and supporting infrastructure, is progressing smoothly.
  • Construction of the Flotation Plant and associated facilities begins this month, April 2025. We anticipate initial plant operations in early Q3 2025, allowing us to conduct thorough testing and optimization of the mill using ore extracted from our ongoing operations. This period of operational testing and fine-tuning will generate measurable economic value and ensure the plant is fully optimized ahead of obtaining complete operational permitting, expected later in the third quarter of 2025.
  • Major repair and maintenance activities on the mining district access road have commenced, providing reliable safe access essential for our project’s successful execution.
