Duquesne West
OVERVIEW
The flagship Duquesne West Gold Property is located 32 km northwest of the city of Rouyn-Noranda and 10 km east of the town of Duparquet. The property lies within the historic Duparquet gold mining camp in the southern portion of the Abitibi Greenstone Belt and is a high-grade Archean Lode Gold Deposit.
The project is close to a highway that leads to Rouyn-Noranda International Airport, has access to a local power supply, and has year-round maintained road access.
Duquesne West hosts a historical inferred mineral resource estimate of 727,000 ounces of gold in 4.17 million tonnes of material grading 5.42 g/t gold. The resource is a greenstone-hosted mesothermal vein system, which occurs throughout the Abitibi gold belt.
Maiden Mineral Resource Estimate - July 2025
Highlights of the Initial Open Pit & Underground Mineral Resource Estimate for the Duquesne West Gold Project:
Inferred Mineral Resource of 26.9 million tonnes (Mt) containing 1.460 million ounces (Moz) of gold (Au) at an average grade of 1.69 grams per tonne (g/t) Au.
The deposit hosts multiple high-grade zones within a broader, lower-grade bulk-tonnage gold envelope. Approximately 44% of the 1.460 Moz is amenable to conceptual open-pit extraction, with the remaining 56% potentially mineable via underground methods.
Significant potential for resource expansion exists in both open-pit and underground environments. Several underexplored zones have been identified within the current pit shell, along strike, and at depth beneath the conceptual pit.
Opportunities exist to enhance the conceptual open-pit grade through further discoveries of high-grade gold zones containing visible gold in areas previously classified as low-grade. This potential was demonstrated in 2024 drilling, which intercepted 22.7 metres at 35.2 g/t Au within the open-pit environment (see Emperor Metals press release, February 25, 2025). Infill drilling has also indicated the potential for meaningful grade improvement, supported by the presence of free gold and low sulfide content.
A summer drill program totaling approximately 8,000 to 10,000 metres is scheduled to commence in August. The program aims to expand the current resource and further advance the project.
Previous Drilling
The 2023 drill results were instrumental in refining our A.I. models, significantly improving our ability to identify high-priority targets for the 2024 drill season. Our exploration strategy continues to focus on increasing potential ounces in preparation for a future mineral resource update. In 2024, drilling efforts prioritized the open pit concept, with the goal of expanding its footprint and adding ounces in a cost-effective manner. The 8,166-meter drill program, completed in October 2024, built on the success of the 2023 campaign and targeted resource expansion, stripping ratio optimization, and de-risking a potential mining scenario based on a newly developed conceptual open-pit model, which complements the existing historical underground framework.
Project Location - Abitibi Greenstone Belt
OPTION AGREEMENT
Emperor Metals has the option to acquire 100% ownership of the project from Globex Mining. The earn-in requires $10 million in payments, 15 million shares and $12 million in exploration expenditures over five years.
