Duquesne West

OVERVIEW

The flagship Duquesne West Gold Project is located in Quebec’s prolific Abitibi Greenstone Belt, approximately 32 km northwest of Rouyn-Noranda and 10 km east of Duparquet, within the historic Duparquet Gold Camp. The project is a high-grade Archean lode gold system with excellent infrastructure, including year-round road access, nearby power, and direct highway access to Rouyn-Noranda International Airport.

Duquesne West hosts a large-scale gold system with both open-pit and underground development potential.

Maiden Mineral Resource Estimate - July 2025

Resource Highlights

  • Inferred Mineral Resource:
    26.9 Mt containing 1.460 Moz Au grading 1.69 g/t Au
  • Deposit characterized by multiple high-grade zones within a broader bulk-tonnage gold envelope
  • Approximately:
    • 44% of ounces considered conceptually open-pit amenable
    • 56% potentially mineable via underground methods
  • Significant upside remains:
    • Within the current pit shell
    • Along strike
    • At depth below the conceptual pit
  • 2024 drilling demonstrated strong high-grade potential, including:
    • 22.7 m @ 35.2 g/t Au
      (see Emperor Metals news release dated February 25, 2025)
  • Ongoing infill drilling continues to support potential grade enhancement and resource growth

2026 Drill Program

A fully funded ~10,000 metre drill program is currently underway and focused on:

  • Expanding the existing resource
  • Testing high-priority growth targets
  • Advancing both open-pit and underground development concepts
  • Supporting future resource updates

Exploration & AI Targeting

Results from the 2023 drilling campaign were integrated into Emperor’s proprietary A.I.-assisted targeting models, helping refine and prioritize targets for subsequent drilling.

The 2024 campaign totaled 8,166 metres and focused on:

  • Expanding the conceptual open pit footprint
  • Increasing potential ounces in a cost-effective manner
  • Optimizing stripping ratios
  • De-risking future mining scenarios
  • Advancing a new conceptual open-pit model alongside the historical underground framework

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.
