Stakeholder Gold Advances 3D Geophysical Modelling and Launches 1,250-Sample Soil Survey at Yukon’s Loki Copper Corridor

Completion of 3D Geophysical Inversions to Enhance Copper Targeting

Stakeholder Gold is finalizing advanced three-dimensional inversion modelling of geophysical datasets to improve understanding of the Loki copper system. This includes 3D inversion of historical helicopter-borne VTEM (versatile time-domain electromagnetic) data acquired in 2017 by Geotech Ltd. over the Loki Copper Zone, along with 3D inversion of UAV magnetic data collected in 2024 by Overhead Intelligence Inc. covering the Loki and Loki West targets. GroundTruth Exploration Ltd. is completing data processing.

The resulting 3D resistivity and magnetic susceptibility models are anticipated to significantly enhance copper drill targeting along the Loki structural corridor by resolving conductive, potentially sulphide-associated features and related structures at depth. According to the July 28, 2026 announcement, this modelling is nearing completion and will provide valuable insights into the mineralized intrusions targeted for drilling.

Extensive Soil Geochemical Survey Planned for Loki West and Loki East

Following the geophysical inversion work, Stakeholder Gold plans a comprehensive 1,250-sample soil geochemical survey across the Loki West and newly staked Loki East targets. This program aims to delineate and expand copper-in-soil anomalies identified along the Loki structural corridor. Concurrent prospecting will systematically assess the newly staked Loki East target at the corridor’s southeastern extension for the first time.

Fieldwork is scheduled to begin as soon as crews can be deployed, though no specific start date has been provided. Integration of soil geochemical results with the completed 3D VTEM and magnetic inversion models will guide prioritization and refinement of copper drill targets ahead of future drilling campaigns.

Prime Location Adjacent to Coffee Gold Mine Project

The Ballarat Gold-Copper Project occupies a highly strategic position in Yukon’s rapidly developing White Gold District. The property lies immediately northeast and adjacent to Talamore Mining’s Coffee Gold Mine Project, one of Canada’s newest gold mines currently under development.

The Northern Access Route (NAR), under construction to serve the Coffee Gold Mine Project, crosses the center of the Ballarat property, delivering 20 km of new mine-grade road infrastructure directly across Stakeholder’s claims. This infrastructure significantly improves access for exploration and development activities on Stakeholder’s land, positioning the company advantageously amid district-wide advancement.

Expansion of Loki Structural Corridor Coverage

Stakeholder Gold recently staked the Loki East target, extending its coverage of the prospective Loki structural corridor to the southeast. This ground expansion enables systematic evaluation of a larger portion of what management considers one of the district’s most prospective copper corridors. The Loki structural corridor traverses the heart of the Ballarat property and benefits from direct access via the Coffee Mine’s Northern Access Route.

The newly staked Loki East claims will be included as a priority in the 2026 soil geochemical and prospecting programs. The announcement does not specify the exact size or number of claims associated with the Loki East staking.

Ballarat Project Holdings and Dual Exploration Focus

Stakeholder Gold holds 100% ownership of 1,140 contiguous mineral claims covering 22,700 hectares and spanning 20 km of the Coffee Mine Project’s Northern Access Route through the White Gold District’s geographic center. Additionally, the company holds 10 claims within the adjacent Coffee Mine Project area owned by Talamore Mining Corp. Collectively, these claims constitute the Ballarat Gold-Copper Project.

Within these holdings, Stakeholder is advancing exploration on two primary targets: the Skye Gold Zone and the Loki Copper Zone. Separated by approximately 8 km, these targets offer potential for new gold and copper discoveries respectively, located on either side of the Northern Access Route in the core of the White Gold District.

White Gold District Overview and Industry Developments

The White Gold District in Yukon has emerged as one of Canada’s most active new mine development regions, with Talamore Mining’s Coffee Gold Mine Project progressing toward production. The district attracts significant mineral exploration investment and development activity nationwide. Stakeholder’s strategic positioning adjacent to the Coffee Mine Project provides exploration and future development advantages.

The Northern Access Route’s construction through Stakeholder’s Ballarat property offers unique infrastructure benefits, supporting exploration efficiency and potential future development. The company highlights the timing advantage of its current programs amid ongoing district-wide development.

Management Insights on 2026 Field Season Priorities

Christopher Berlet, CEO and Director of Stakeholder Gold, emphasized that refining the understanding of the Loki copper system is a top priority for the 2026 field season. He noted that 3D VTEM and magnetic inversions are delivering an increasingly detailed three-dimensional view of the Loki structural corridor, with upcoming soil and prospecting programs expanding this understanding across the Loki West and newly staked Loki East targets.

Berlet highlighted the company’s approach of combining advanced 3D geophysical modelling with systematic soil geochemistry and prospecting to develop a strong pipeline of high-quality copper and critical mineral exploration targets. He underscored the significant exploration potential of the Loki structural corridor, centrally located on the Ballarat property with direct access via the Coffee Mine’s Northern Access Route, within one of Canada’s most active new mine development districts.

Complementary Cash Flow from Brazilian Operations

Alongside its Yukon exploration, Stakeholder Gold generates cash flow through its wholly owned Brazilian subsidiary Mineração VMC Ltda. (VMC). The subsidiary operates four independent stone quarries and is exploring opportunities to expand sales and exports of exotic stone building materials from Brazil. This diversified revenue stream supports the company’s operational cash generation independent of exploration activities.

These parallel operations in Brazil help fund ongoing exploration expenditures, though the announcement does not disclose current production figures, revenue, or expansion timelines for VMC.
