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 third quarter of 2025, we share the following updates and forward-looking approach to our mining and exploration activities.
ACCOMPLISHMENTS
Operations and Plan Development
Antonino Tunnel – Fortuna Project
During this quarter, we made substantial progress at our Fortuna site. Our contractor successfully completed structural upgrades to the Antonino Tunnel, including improvements to the portal, the access slope, and the necessary conditions to initiate mineral production.
We remain focused on beginning mineral extraction from Fortuna within the current quarter and reaching a regular production level of 1,000 tons per month in the following quarter.

In parallel, our Geology team has completed a technical plan to expand production capacity at Fortuna from 1,000 to 3,000 tons per month. This will be achieved through horizontal extensions of the existing tunnel network, accessing nearby vein systems and ore from the upper level historically referred to as Fortuna 1913. It is important to clarify that these extensions do not involve vertical mining or structural changes to the historic mining layout.
To execute this expansion, we will apply for a new exploitation permit in addition to the current one already in place for Fortuna. We anticipate submitting the permit application in the coming weeks and expect approval by the end of 2025. Until then, operations at Fortuna will continue under the existing authorization at 1,000 tons per month.
Caren Project
We have submitted the required application for an exploitation permit at the Caren project with an initial production capacity of 1,000 tons per month. Once this permit is granted and operations commence, we will evaluate the feasibility of scaling Caren’s capacity based on operational data and performance. We anticipate receiving the permit in the coming weeks.
Mineral Flotation Plant & Supporting Infrastructure
Site preparation activities for our Mineral Flotation Plant are progressing on schedule. Clearing and grading are complete, and our contractor is currently placing foundational material — including concrete and boulders — for the construction of the plant.
Additional infrastructure is also advancing. Notably, construction of the Main Warehouse is well underway. Meanwhile, tailings dam construction is planned to begin in September 2025, following the completion of foundational groundwork.

We have submitted all required permit applications for both the Flotation Plant and the Tailings Dam. These are proceeding through the appropriate regulatory channels, and we expect to receive the necessary approvals in the coming months.

FORWARD-LOOKING STATEMENTS
This news release contains certain forward-looking statements within the meaning of the United States Securities Exchange Act of 1934, as amended. This forward-looking information includes, or may be based upon estimates, forecasts and statements of management’s expectations with respect to, among other things, the completion of transactions, the issuance of permits, the size and quality of mineral resources, future trends for the company, progress in development of mineral properties, future production and sales volumes, capital costs, mine production costs, demand and market outlook for metals, future metal prices and treatment and refining or milling charges, the outcome of legal proceedings, the timing of exploration, development and mining activities, acquisition of shares in other companies and the financial results of the company. There can be no assurances that such statements will prove to be accurate and actual results and future events could differ materially and substantially from those anticipated in such statements. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that mineral resources will be converted into mineral reserves.
