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 large-scale Archean gold system with excellent infrastructure, including year-round road access, nearby hydroelectric power and direct highway access to Rouyn-Noranda.

Duquesne West currently hosts an Inferred Mineral Resource of 1.46 million ounces of gold and is being systematically advanced toward a significantly larger resource through aggressive drilling, AI-assisted targeting and a phased development strategy. Recent drilling continues to demonstrate broad zones of near-surface mineralization alongside exceptional high-grade intercepts, supporting the potential for both open-pit and underground mining scenarios.

The Company's current strategy is focused on defining a Phase 1 open-pit operation that could reduce initial capital requirements, simplify permitting and accelerate the project's path toward development while continuing to grow the overall gold system.

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
  • Multiple high-grade zones within a broad bulk-tonnage gold system
  • Approximately:
    • 44% of ounces conceptually open-pit amenable
    • 56% potentially mineable by underground methods
  • Significant upside:
    • Within the current pit shell
    • Along strike, at depth
  • Resource expected to continue evolving through ongoing drilling

2026 Drill Program
The fully funded 15,000 m drill program, together with approximately 8,000 m of historical core resampling, is designed to expand and upgrade the existing resource.

Objectives

  • Expand the conceptual open pit
  • Grow near-surface ounces
  • Test high-priority step-out targets
  • Support future resource updates
  • Advance a phased development strategy

Recent Highlights

  • 15.0 m @ 61.5 g/t Au, including 2.4 m @ 369.6 g/t Au
  • 35.9 m @ 3.1 g/t Au, including 24.7 m @ 4.0 g/t Au
  • Broad zones of near-surface mineralization continue to support both resource growth and potential improvements to future mine economics.

Exploration & AI Targeting
Emperor continues to integrate drilling results into its proprietary AI-assisted geological models to refine targeting and improve drill efficiency. The exploration strategy is focused on outlining broad, lower-grade mineralized halos surrounding established high-grade shoots, with the goal of increasing total ounces while enhancing the economics of a future open-pit operation.

Optiom Agreement 
Emperor Metals has the option to acquire a 100% interest in the project from Globex Mining. The earn-in requires $10 million in cash payments, 15 million common shares, and $12 million in exploration expenditures over a five-year period.
