OVERVIEW
OF THE FOX COMPLEX

The Fox Complex benefits from its location in an established mining district with excellent infrastructure, access to skilled labor, and a long history of gold production. Since 1915, the properties have produced approximately 3.5 million ounces of gold, underscoring the scale and endowment of the district.

The operation currently produces from the Froome Mine while advancing additional deposits toward production. The properties span approximately 30 kilometers of structural controls along the Destor-Porcupine Fault—known as the “Golden Highway”—a prolific regional structure hosting many of the richest gold mines in Ontario and Quebec. This setting provides significant exploration and development potential.

With several deposits at different stages of development, the Fox Complex provides operational flexibility and the ability to sequence mining activities over time. This integrated approach supports production growth, cost optimization, and extended mine life, positioning the Fox Complex as a scalable platform for long-term growth in the Timmins district.

In 2025, the Fox Complex produced approximately 23,000 gold equivalent ounces (GEOs). In 2026, production is expected to be 20,000 to 23,000 GEOs (without including production from Stock), as development advances at Froome West and the Stock Mine moves toward initial production.

The Grey Fox Pre-Feasibility Study (PFS), announced in June 2026, transforms the Fox Complex from a collection of development-stage assets into a long-life, multi-deposit production platform extending to 2041. With Grey Fox entering production, the Fox Complex is projected to reach approximately 100,000 gold ounces production in 2029 and average approximately 87,000 gold ounces per year from 2028 through 2041.

This production growth will also contribute to the Company's near-term objective of increasing consolidated annual production to 250,000–300,000 GEOs by 2030.

FOX COMPLEX INFRASTRUCTURE

The Fox Complex is supported by the Stock Mill, a centralized processing hub that enables multiple deposits to be developed and integrated efficiently. The Stock Mill is a conventional processing facility supporting ore from underground and future open pit sources. Additional infrastructure, including underground development, haulage routes and site services, supports the processing of material and the advancement of new mining areas.

The Grey Fox development benefits significantly from existing infrastructure, including the Stock Mill, permitted tailings facilities, and an established operating workforce, reducing development capital requirements and supporting attractive project economics.

PRODUCTION & DEVELOPMENT

Production at the Fox Complex is currently sourced from the Froome Mine through underground mining, which continues to provide a reliable and consistent feed to the Stock Mill. Recent drilling at Froome West has extended mineralization both along strike and at depth, supporting continued production and potential mine life extensions.

The Stock Mine represents the next step of production growth, with development advancing on time and within the initial budget. Mineralized material encountered during ramp development has been sent to the mill and mining is expected to begin in Q4 2026, with commercial production in 2027. As Froome matures and Grey Fox advances, Stock is expected to enhance operational flexibility and support the phased ramp-up of production across the complex. Its proximity to the mill, lower royalties, and softer mineralized material are expected to position Stock Mine as a source of lower-cost production. Based on the current Mineral Resource Estimate and the results of additional engineering and mine planning during Q2 2026, the team at the Stock Mine believes the mine life can be extended to 8.5 years from the previously disclosed 6 years. Additional underground drilling has the potential to further extend the mine life.

Grey Fox is the primary long-term growth driver and largest gold deposit within the Fox Complex. The 2026 Pre-Feasibility Study outlines an underground mining operation accessed from two independent portals that is expected to become the foundation of future production at the Fox Complex. Grey Fox ore will be crushed on site and hauled to the Stock Mill for processing. At the Stock Mill, the ore will undergo grinding and processing through a Carbon-In-Leach (CIL) circuit before being refined into doré. Mining at Grey Fox will support a significant increase in the annual gold output for Fox, extending the mine life of the complex into 2041. Next steps for the project include 1) Completing detailed engineering and initiating long-lead purchases, 2) Submitting water permit and closure plan, 3) H1 2027 construction, and 4) 2029 commercial production.

Exploration is a key component of the Fox Complex, which is located within the Abitibi Greenstone Belt—one of the world’s most prolific gold districts. Gold mineralization across the property occurs in multiple styles, including quartz veins, stockworks, and sulphide-hosted systems associated with strong alteration zones, reflecting the geological complexity and potential of the district.

Despite a long history of exploration and production, the Fox Complex remains relatively underexplored, with multiple prospective structural trends and targets identified across the property.

Recent results at Froome West have extended high-grade mineralization along strike and at depth, supporting potential mine life extensions and additional resource growth.

Exploration is closely integrated with development activities, including planned parallel drilling at Stock and other deposits to support future resource growth and production as mining advances.

At Grey Fox, active drilling has demonstrated strong continuity and expansion potential across multiple zones. Its 2026 exploration program is continuing with five drills operating and a $5.0 million budget.

In Q2 2026, exploration drilling focused on Whiskey Jack, Gibson and Grey Fox South, returning multiple high-grade intersections with the potential to expand the current Mineral Resource Estimate and extend the planned mine life beyond 2041. Highlight results include 97.7 gpt gold over 4.4 meters, 64.8 gpt gold over 3.3 meters and 32.5 gpt gold over 5.2 meters (true widths). At Grey Fox South, drilling also discovered a new mineralized zone approximately 850 meters southeast of the current Mineral Resource Estimate, highlighting the continued exploration potential across the project.

Continued exploration investment supports resource growth and conversion, reinforcing Grey Fox’s role as the primary long-term growth driver for the Fox Complex.
