Emperor Metals Mobilizes Drill Rig to Advance Duquesne West Exploration

Oct 28, 2025

Vancouver, British Columbia, October 28, 2025 – Emperor Metals Inc. (“Emperor”) (CSE: AUOZ, OTCQB: EMAUF, FSE: 9NH) is pleased to announce the resumption of its ongoing drilling program, following the release of our Maiden Mineral Resource Estimate (MMRE) update (see press release dated July 9, 2025).

CEO John Florek commented: “We’re excited to resume drilling following the successful closing of our $11.1 million financing. These funds will advance exploration and development at both the Duquesne West and Lac Pelletier Gold Deposits.

At Duquesne West alone, over 120,000 meters of historical drilling has already been completed; yet we believe this represents only 15–20% of the drilling ultimately required to fully delineate the deposit above 1,000 meters vertical depth. This positions us for substantial upside potential in both resource expansion and contained gold ounces.”

The Duquesne West deposit demonstrates multiple high-grade gold zones hosted within a broader, lower-grade bulk-tonnage envelope. Approximately 44% of the current 1.46-million-ounce resource announced in our MMRE is considered amenable to conceptual open-pit extraction, while the remaining 56% is potentially mineable via conceptual underground methods (see press release dated July 9, 2025).

¹As disclosed in the technical report filed on SEDAR+ on August 25, 2025, the Duquesne West Gold Project hosts an Inferred Mineral Resource of 27.3 million tonnes grading 1.69 grams per tonne (g/t) gold (Au), containing 1.460 million troy ounces of gold. The estimate includes both open-pit and underground extraction scenarios and has been prepared in accordance with the CIM Definition Standards (2014) and NI 43-101. Sensitivity tables related to cut-off grades and resource confidence are provided in Table 3 of this document. The mineral resource is constrained by a conceptual pit shell and underground stope shapes to demonstrate reasonable prospects for eventual economic extraction. The mineralized system remains open for potential resource expansion.

This next phase of delineation drilling will be strategically focused, with a planned10,000 to 15,000 meters of drilling. The primary objectives include:

Expanding the open pit footprint;
Adding incremental ounces within host rock surrounding high-grade lenses; and
Twinning select historical drillholes; particularly those either excluded from the MMRE or downgraded to the Inferred category due to the absence of preserved core or collar data required to validate their classification.
Continue assaying unsampled historical core within the conceptual open-pit boundaries.

The 2024 exploration efforts have demonstrated significant potential for resource expansion both within and along strike of the conceptual open pit. This includes the discovery of previously unrecognized low-grade bulk tonnage zones, as well as high-grade gold lenses containing visible gold in our conceptual open pit boundaries (See Figures 1).

The 2025 program will represent a strategic continuation of the highly successful drilling campaigns conducted in 2023, 2024, and in earlier years. Key highlights from the 2023 and 2024 drilling programs are presented in Table 1.

Table 2 presents a summary of notable interceptions from historical drillholes completed by previous operators. These results highlight the significant thicknesses and grades encountered prior to our acquisition of the project. Importantly, the 2023 and 2024 drilling campaigns conducted by Emperor Metal successfully extended these mineralized zones, playing a key role in the subsequent expansion of the deposit’s inferred resource.

Overall Strategic Plan

The 2025 drilling campaign at Emperor’s Duquesne West Gold Project in Quebec will comprise two integrated components. The first is an 8,000-metre historical core sampling program focused on assaying previously unsampled, lower-grade gold zones, with the objective of adding incremental ounces to the near-surface, open-pit resource. This initiative will also enhance geological modelling and increase confidence in existing mineralized zones, contributing to potential future economic optimization. The second component is a 10,000 to 15,000-metre diamond drilling program, scheduled to commence in November 2025, targeting step-out zones and potential resource expansion. Together, these programs are designed to systematically de-risk the project, refine the geological framework, and support future resource growth and economic assessments.

The 2025 season key components:

Expand the Open Pit Footprint: Target additional discoveries within the host rock containing high-grade gold lenses, focusing on the conceptual open-pit model.
Increase the Thickness of the High-Grade Lenses: Incorporate previously unaccounted lower-grade gold from the margins of high-grade lenses and continue to enhance their overall thickness.
Expand Mineralized Zones: Extend the lateral footprint of mineralized zones along strike and dip.
Discover New Zones: Explore potential new zones not yet included in the conceptual open-pit model, with a particular focus on eastward expansion.
Validate Historical Zones: Confirm existing high grade historical zones along plunge to determine extent of mineralization and bring inferred material into measured and indicted categories.

About the Duquesne West Gold Project

The Duquesne West Gold Property is located 32 km northwest of the city of Rouyn-Noranda and 10 km east of the town of Duparquet, Quebec, Canada. The property lies within the historic Duparquet gold mining camp in the southern portion of the Abitibi Greenstone Belt in the Superior Province.

Under an Option Agreement, Emperor agreed to acquire a 100% interest in a mineral claim package comprising 38 claims covering approximately 1,389 ha, located in the Duparquet Township of Quebec (the “Duquesne West Property”) from Duparquet Assets Ltd., a 50% owned subsidiary of Globex Mining Enterprises Inc. (GMX-TSX). For further information on the Duquesne West Property and Option Agreement, see Emperor’s press release dated Oct. 12, 2022, available on SEDAR.

The 2025 Mineral Resource Estimate (MRE) for the Duquesne West Project outlines an Inferred Mineral Resource of 27.3 million tonnes, containing 1.460 million troy ounces of gold at an average grade of 1.69 g/t Au, across both open-pit and underground mining scenarios2. The full technical report was filed on SEDAR+ on August 25, 2025. Sensitivity analyses supporting the estimate are presented in Table 3. Importantly, the gold system remains open along strike and at depth, highlighting strong potential for further resource growth and delineation.

Mineral resources that are not mineral reserves do not have demonstrated economic viability.

A reinterpretation of the existing geological model was created using AI and Machine Learning. This model shows the opportunity for additional discovery of ounces by revealing gold trends unknown to previous workers and the potential to expand the resource along significant gold- endowed structural zones.

Multiple scenarios exist to expand additional resources which include:

Underground High-Grade Gold.
Open Pit Bulk Tonnage Gold.
Underground Bulk Tonnage Gold.
